摘要

This document provides information about installing OpenShift Container Platform and details about some configuration processes.

第 1 章 Mirroring images for a disconnected installation

Before you install a cluster on infrastructure that you provision in a restricted network, you must mirror the required container images into that environment. You can also use this procedure in unrestricted networks to ensure your clusters only use container images that have satisfied your organizational controls on external content.

重要

You must have access to the internet to obtain the necessary container images. In this procedure, you place the mirror registry on a mirror host that has access to both your network and the Internet. If you do not have access to a mirror host, use the disconnected procedure to copy images to a device you can move across network boundaries with.

1.1. Prerequisites

You must have a container image registry that supports Docker v2-2 in the location that will host the OpenShift Container Platform cluster, such as one of the following registries:
If you have an entitlement to Red Hat Quay, see the documentation on deploying Red Hat Quay for proof-of-concept purposes or by using the Quay Operator. If you need additional assistance selecting and installing a registry, contact your sales representative or Red Hat support.

1.2. About the mirror registry

You can mirror the images that are required for OpenShift Container Platform installation and subsequent product updates to a mirror registry. These actions use the same process. The release image, which contains the description of the content, and the images it references are all mirrored. In addition, the Operator catalog source image and the images that it references must be mirrored for each Operator that you use. After you mirror the content, you configure each cluster to retrieve this content from your mirror registry.

The mirror registry can be any container registry that supports Docker v2-2. All major cloud provider registries, as well as Red Hat Quay, Artifactory, and others, have the necessary support. Using one of these registries ensures that OpenShift Container Platform can verify the integrity of each image in disconnected environments.

The mirror registry must be reachable by every machine in the clusters that you provision. If the registry is unreachable installation, updating, or normal operations such as workload relocation might fail. For that reason, you must run mirror registries in a highly available way, and the mirror registries must at least match the production availability of your OpenShift Container Platform clusters.

When you populate a mirror registry with OpenShift Container Platform images, you can follow two scenarios. If you have a host that can access both the internet and your mirror registry, but not your cluster nodes, you can directly mirror the content from that machine. This process is referred to as connected mirroring. If you have no such host, you must mirror the images to a file system and then bring that host or removable media into your restricted environment. This process is referred to as disconnected mirroring.

1.3. Preparing your mirror host

Before you perform the mirror procedure, you must prepare the host to retrieve content and push it to the remote location.

1.3.1. Installing the CLI by downloading the binary

You can install the OpenShift CLI (oc) in order to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS.

重要

If you installed an earlier version of oc, you cannot use it to complete all of the commands in OpenShift Container Platform 4.5. Download and install the new version of oc.

1.3.1.1. Installing the CLI on Linux

You can install the OpenShift CLI (oc) binary on Linux by using the following procedure.

Procedure

Navigate to the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site.
Select your infrastructure provider, and, if applicable, your installation type.
In the Command line interface section, select Linux from the drop-down menu and click Download command-line tools.
Unpack the archive:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvzf <file>
```
```
$ tar xvzf <file>
```
Place the oc binary in a directory that is on your PATH.
To check your PATH, execute the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
echo $PATH
```
```
$ echo $PATH
```

After you install the CLI, it is available using the oc command:

Copy to Clipboard Toggle word wrap

oc <command>

$ oc <command>

1.3.1.2. Installing the CLI on Windows

You can install the OpenShift CLI (oc) binary on Windows by using the following procedure.

Procedure

Navigate to the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site.
Select your infrastructure provider, and, if applicable, your installation type.
In the Command line interface section, select Windows from the drop-down menu and click Download command-line tools.
Unzip the archive with a ZIP program.
Move the oc binary to a directory that is on your PATH.
To check your PATH, open the command prompt and execute the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
path
```
```
C:\> path
```

After you install the CLI, it is available using the oc command:

Copy to Clipboard Toggle word wrap

oc <command>

C:\> oc <command>

1.3.1.3. Installing the CLI on macOS

You can install the OpenShift CLI (oc) binary on macOS by using the following procedure.

Procedure

Navigate to the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site.
Select your infrastructure provider, and, if applicable, your installation type.
In the Command line interface section, select MacOS from the drop-down menu and click Download command-line tools.
Unpack and unzip the archive.
Move the oc binary to a directory on your PATH.
To check your PATH, open a terminal and execute the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
echo $PATH
```
```
$ echo $PATH
```

After you install the CLI, it is available using the oc command:

Copy to Clipboard Toggle word wrap

oc <command>

$ oc <command>

1.4. Configuring credentials that allow images to be mirrored

Create a container image registry credentials file that allows mirroring images from Red Hat to your mirror.

警告

Do not use this image registry credentials file as the pull secret when you install a cluster. If you provide this file when you install cluster, all of the machines in the cluster will have write access to your mirror registry.

警告

This process requires that you have write access to a container image registry on the mirror registry and adds the credentials to a registry pull secret.

Prerequisites

You configured a mirror registry to use in your restricted network.
You identified an image repository location on your mirror registry to mirror images into.
You provisioned a mirror registry account that allows images to be uploaded to that image repository.

Procedure

Complete the following steps on the installation host:

Download your registry.redhat.io pull secret from the Pull Secret page on the Red Hat OpenShift Cluster Manager site and save it to a .json file.
Generate the base64-encoded user name and password or token for your mirror registry:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
echo -n '<user_name>:<password>' | base64 -w0
```
```
$ echo -n '<user_name>:<password>' | base64 -w0 
```
1
```
BGVtbYk3ZHAtqXs=
```
1
For <user_name> and <password>, specify the user name and password that you configured for your registry.

Make a copy of your pull secret in JSON format:

Copy to Clipboard Toggle word wrap

cat ./pull-secret.text | jq .  > <path>/<pull-secret-file>

$ cat ./pull-secret.text | jq .  > <path>/<pull-secret-file>

1: Specify the path to the folder to store the pull secret in and a name for the JSON file that you create.

The contents of the file resemble the following example:

Copy to Clipboard Toggle word wrap

{
  "auths": {
    "cloud.openshift.com": {
      "auth": "b3BlbnNo...",
      "email": "you@example.com"
    },
    "quay.io": {
      "auth": "b3BlbnNo...",
      "email": "you@example.com"
    },
    "registry.connect.redhat.com": {
      "auth": "NTE3Njg5Nj...",
      "email": "you@example.com"
    },
    "registry.redhat.io": {
      "auth": "NTE3Njg5Nj...",
      "email": "you@example.com"
    }
  }
}

{
  "auths": {
    "cloud.openshift.com": {
      "auth": "b3BlbnNo...",
      "email": "you@example.com"
    },
    "quay.io": {
      "auth": "b3BlbnNo...",
      "email": "you@example.com"
    },
    "registry.connect.redhat.com": {
      "auth": "NTE3Njg5Nj...",
      "email": "you@example.com"
    },
    "registry.redhat.io": {
      "auth": "NTE3Njg5Nj...",
      "email": "you@example.com"
    }
  }
}

Edit the new file and add a section that describes your registry to it:

Copy to Clipboard Toggle word wrap

  "auths": {
    "<mirror_registry>": { 
      "auth": "<credentials>", 
      "email": "you@example.com"
  },

  "auths": {
    "<mirror_registry>": {


      "auth": "<credentials>",


      "email": "you@example.com"
  },

1: For <mirror_registry>, specify the registry domain name, and optionally the port, that your mirror registry uses to serve content. For example, registry.example.com or registry.example.com:5000
2: For <credentials>, specify the base64-encoded user name and password for the mirror registry.

The file resembles the following example:

Copy to Clipboard Toggle word wrap

{
  "auths": {
    "<mirror_registry>": {
      "auth": "<credentials>",
      "email": "you@example.com"
    },
    "cloud.openshift.com": {
      "auth": "b3BlbnNo...",
      "email": "you@example.com"
    },
    "quay.io": {
      "auth": "b3BlbnNo...",
      "email": "you@example.com"
    },
    "registry.connect.redhat.com": {
      "auth": "NTE3Njg5Nj...",
      "email": "you@example.com"
    },
    "registry.redhat.io": {
      "auth": "NTE3Njg5Nj...",
      "email": "you@example.com"
    }
  }
}

{
  "auths": {
    "<mirror_registry>": {
      "auth": "<credentials>",
      "email": "you@example.com"
    },
    "cloud.openshift.com": {
      "auth": "b3BlbnNo...",
      "email": "you@example.com"
    },
    "quay.io": {
      "auth": "b3BlbnNo...",
      "email": "you@example.com"
    },
    "registry.connect.redhat.com": {
      "auth": "NTE3Njg5Nj...",
      "email": "you@example.com"
    },
    "registry.redhat.io": {
      "auth": "NTE3Njg5Nj...",
      "email": "you@example.com"
    }
  }
}

1.5. Mirroring the OpenShift Container Platform image repository

Mirror the OpenShift Container Platform image repository to your registry to use during cluster installation or upgrade.

Prerequisites

Your mirror host has access to the Internet.
You configured a mirror registry to use in your restricted network and can access the certificate and credentials that you configured.
You downloaded the pull secret from the Pull Secret page on the Red Hat OpenShift Cluster Manager site and modified it to include authentication to your mirror repository.
If you use self-signed certificates that do not set a Subject Alternative Name, you must precede the oc commands in this procedure with GODEBUG=x509ignoreCN=0. If you do not set this variable, the oc commands will fail with the following error:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
x509: certificate relies on legacy Common Name field, use SANs or temporarily enable Common Name matching with GODEBUG=x509ignoreCN=0
```
```
x509: certificate relies on legacy Common Name field, use SANs or temporarily enable Common Name matching with GODEBUG=x509ignoreCN=0
```

Procedure

Complete the following steps on the mirror host:

Review the OpenShift Container Platform downloads page to determine the version of OpenShift Container Platform that you want to install and determine the corresponding tag on the Repository Tags page.
Set the required environment variables:
1. Export the release version:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
OCP_RELEASE=<release_version>
```
```
$ OCP_RELEASE=<release_version>
```
  For <release_version>, specify the tag that corresponds to the version of OpenShift Container Platform to install, such as 4.5.4.
2. Export the local registry name and host port:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
LOCAL_REGISTRY='<local_registry_host_name>:<local_registry_host_port>'
```
```
$ LOCAL_REGISTRY='<local_registry_host_name>:<local_registry_host_port>'
```
  For <local_registry_host_name>, specify the registry domain name for your mirror repository, and for <local_registry_host_port>, specify the port that it serves content on.
3. Export the local repository name:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
LOCAL_REPOSITORY='<local_repository_name>'
```
```
$ LOCAL_REPOSITORY='<local_repository_name>'
```
  For <local_repository_name>, specify the name of the repository to create in your registry, such as ocp4/openshift4.
4. Export the name of the repository to mirror:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
PRODUCT_REPO='openshift-release-dev'
```
```
$ PRODUCT_REPO='openshift-release-dev'
```
  For a production release, you must specify openshift-release-dev.
5. Export the path to your registry pull secret:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
LOCAL_SECRET_JSON='<path_to_pull_secret>'
```
```
$ LOCAL_SECRET_JSON='<path_to_pull_secret>'
```
  For <path_to_pull_secret>, specify the absolute path to and file name of the pull secret for your mirror registry that you created.
6. Export the release mirror:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
RELEASE_NAME="ocp-release"
```
```
$ RELEASE_NAME="ocp-release"
```
  For a production release, you must specify ocp-release.
7. Export the type of architecture for your server, such as x86_64.:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ARCHITECTURE=<server_architecture>
```
```
$ ARCHITECTURE=<server_architecture>
```
8. Export the path to the directory to host the mirrored images:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
REMOVABLE_MEDIA_PATH=<path>
```
```
$ REMOVABLE_MEDIA_PATH=<path> 
```
  1
  1
  Specify the full path, including the initial forward slash (/) character.

Mirror the version images to the internal container registry:

If your mirror host does not have Internet access, take the following actions:

Connect the removable media to a system that is connected to the Internet.

Review the images and configuration manifests to mirror:

Copy to Clipboard Toggle word wrap

oc adm release mirror -a ${LOCAL_SECRET_JSON}  \
     --from=quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-${ARCHITECTURE} \
     --to=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY} \
     --to-release-image=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE}-${ARCHITECTURE} --dry-run

$ oc adm release mirror -a ${LOCAL_SECRET_JSON}  \
     --from=quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-${ARCHITECTURE} \
     --to=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY} \
     --to-release-image=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE}-${ARCHITECTURE} --dry-run

Record the entire imageContentSources section from the output of the previous command. The information about your mirrors is unique to your mirrored repository, and you must add the imageContentSources section to the install-config.yaml file during installation.

Mirror the images to a directory on the removable media:

Copy to Clipboard Toggle word wrap

oc adm release mirror -a ${LOCAL_SECRET_JSON} --to-dir=${REMOVABLE_MEDIA_PATH}/mirror quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-${ARCHITECTURE}

$ oc adm release mirror -a ${LOCAL_SECRET_JSON} --to-dir=${REMOVABLE_MEDIA_PATH}/mirror quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-${ARCHITECTURE}

Take the media to the restricted network environment and upload the images to the local container registry.

Copy to Clipboard Toggle word wrap

oc image mirror -a ${LOCAL_SECRET_JSON} --from-dir=${REMOVABLE_MEDIA_PATH}/mirror "file://openshift/release:${OCP_RELEASE}*" ${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}

$ oc image mirror -a ${LOCAL_SECRET_JSON} --from-dir=${REMOVABLE_MEDIA_PATH}/mirror "file://openshift/release:${OCP_RELEASE}*" ${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}

1: For REMOVABLE_MEDIA_PATH, you must use the same path that you specified when you mirrored the images.

If the local container registry is connected to the mirror host, take the following actions:
1. Directly push the release images to the local registry by using following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm release mirror -a ${LOCAL_SECRET_JSON}  \
     --from=quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-${ARCHITECTURE} \
     --to=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY} \
     --to-release-image=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE}-${ARCHITECTURE}
```
```
$ oc adm release mirror -a ${LOCAL_SECRET_JSON}  \
     --from=quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-${ARCHITECTURE} \
     --to=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY} \
     --to-release-image=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE}-${ARCHITECTURE}
```
  This command pulls the release information as a digest, and its output includes the imageContentSources data that you require when you install your cluster.
2. Record the entire imageContentSources section from the output of the previous command. The information about your mirrors is unique to your mirrored repository, and you must add the imageContentSources section to the install-config.yaml file during installation.
  注意
  The image name gets patched to Quay.io during the mirroring process, and the podman images will show Quay.io in the registry on the bootstrap virtual machine.

To create the installation program that is based on the content that you mirrored, extract it and pin it to the release:

If your mirror host does not have Internet access, run the following command:

Copy to Clipboard Toggle word wrap

oc adm release extract -a ${LOCAL_SECRET_JSON} --command=openshift-install "${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE}"

$ oc adm release extract -a ${LOCAL_SECRET_JSON} --command=openshift-install "${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE}"

If the local container registry is connected to the mirror host, run the following command:

Copy to Clipboard Toggle word wrap

oc adm release extract -a ${LOCAL_SECRET_JSON} --command=openshift-install "${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE}-${ARCHITECTURE}"

$ oc adm release extract -a ${LOCAL_SECRET_JSON} --command=openshift-install "${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE}-${ARCHITECTURE}"

重要

To ensure that you use the correct images for the version of OpenShift Container Platform that you selected, you must extract the installation program from the mirrored content.

You must perform this step on a machine with an active Internet connection.

If you are in a disconnected environment, use the --image flag as part of must-gather and point to the payload image.

1.6. The Cluster Samples Operator in a disconnected environment

In a disconnected environment, you must take additional steps after you install a cluster to configure the Cluster Samples Operator. == Next steps

Mirror the OperatorHub images for the Operators that you want to install in your cluster.
Install a cluster on infrastructure that you provision in your restricted network, such as on VMware vSphere, bare metal, or Amazon Web Services.

1.7. Additional resources

See Gathering data about specific features for more information about using must-gather.

第 2 章 Installing on AWS

2.1. Configuring an AWS account

Before you can install OpenShift Container Platform, you must configure an Amazon Web Services (AWS) account.

2.1.1. Configuring Route 53

To install OpenShift Container Platform, the Amazon Web Services (AWS) account you use must have a dedicated public hosted zone in your Route 53 service. This zone must be authoritative for the domain. The Route 53 service provides cluster DNS resolution and name lookup for external connections to the cluster.

Procedure

Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through AWS or another source.
注意
If you purchase a new domain through AWS, it takes time for the relevant DNS changes to propagate. For more information about purchasing domains through AWS, see Registering Domain Names Using Amazon Route 53 in the AWS documentation.
If you are using an existing domain and registrar, migrate its DNS to AWS. See Making Amazon Route 53 the DNS Service for an Existing Domain in the AWS documentation.
Create a public hosted zone for your domain or subdomain. See Creating a Public Hosted Zone in the AWS documentation.
Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.
Extract the new authoritative name servers from the hosted zone records. See Getting the Name Servers for a Public Hosted Zone in the AWS documentation.
Update the registrar records for the AWS Route 53 name servers that your domain uses. For example, if you registered your domain to a Route 53 service in a different accounts, see the following topic in the AWS documentation: Adding or Changing Name Servers or Glue Records.
If you are using a subdomain, add its delegation records to the parent domain. This gives Amazon Route 53 responsibility for the subdomain. Follow the delegation procedure outlined by the DNS provider of the parent domain. See Creating a subdomain that uses Amazon Route 53 as the DNS service without migrating the parent domain in the AWS documentation for an example high level procedure.

2.1.2. AWS account limits

The OpenShift Container Platform cluster uses a number of Amazon Web Services (AWS) components, and the default Service Limits affect your ability to install OpenShift Container Platform clusters. If you use certain cluster configurations, deploy your cluster in certain AWS regions, or run multiple clusters from your account, you might need to request additional resources for your AWS account.

The following table summarizes the AWS components whose limits can impact your ability to install and run OpenShift Container Platform clusters.

Component	Number of clusters available by default	Default AWS limit	Description
Instance Limits	Varies	Varies	By default, each cluster creates the following instances: One bootstrap machine, which is removed after installation Three master nodes Three worker nodes These instance type counts are within a new account’s default limit. To deploy more worker nodes, enable autoscaling, deploy large workloads, or use a different instance type, review your account limits to ensure that your cluster can deploy the machines that you need. In most regions, the bootstrap and worker machines uses an `m4.large` machines and the master machines use `m4.xlarge` instances. In some regions, including all regions that do not support these instance types, `m5.large` and `m5.xlarge` instances are used instead.
Elastic IPs (EIPs)	0 to 1	5 EIPs per account	To provision the cluster in a highly available configuration, the installation program creates a public and private subnet for each availability zone within a region. Each private subnet requires a NAT Gateway, and each NAT gateway requires a separate elastic IP. Review the AWS region map to determine how many availability zones are in each region. To take advantage of the default high availability, install the cluster in a region with at least three availability zones. To install a cluster in a region with more than five availability zones, you must increase the EIP limit. 重要 To use the `us-east-1` region, you must increase the EIP limit for your account.
Virtual Private Clouds (VPCs)	5	5 VPCs per region	Each cluster creates its own VPC.
Elastic Load Balancing (ELB/NLB)	3	20 per region	By default, each cluster creates internal and external network load balancers for the master API server and a single classic elastic load balancer for the router. Deploying more Kubernetes `Service` objects with type `LoadBalancer` will create additional load balancers.
NAT Gateways	5	5 per availability zone	The cluster deploys one NAT gateway in each availability zone.
Elastic Network Interfaces (ENIs)	At least 12	350 per region	The default installation creates 21 ENIs and an ENI for each availability zone in your region. For example, the `us-east-1` region contains six availability zones, so a cluster that is deployed in that zone uses 27 ENIs. Review the AWS region map to determine how many availability zones are in each region. Additional ENIs are created for additional machines and elastic load balancers that are created by cluster usage and deployed workloads.
VPC Gateway	20	20 per account	Each cluster creates a single VPC Gateway for S3 access.
S3 buckets	99	100 buckets per account	Because the installation process creates a temporary bucket and the registry component in each cluster creates a bucket, you can create only 99 OpenShift Container Platform clusters per AWS account.
Security Groups	250	2,500 per account	Each cluster creates 10 distinct security groups.

2.1.3. Required AWS permissions

When you attach the AdministratorAccess policy to the IAM user that you create in Amazon Web Services (AWS), you grant that user all of the required permissions. To deploy all components of an OpenShift Container Platform cluster, the IAM user requires the following permissions:

2.1.4. Creating an IAM user

Each Amazon Web Services (AWS) account contains a root user account that is based on the email address you used to create the account. This is a highly-privileged account, and it is recommended to use it for only initial account and billing configuration, creating an initial set of users, and securing the account.

Before you install OpenShift Container Platform, create a secondary IAM administrative user. As you complete the Creating an IAM User in Your AWS Account procedure in the AWS documentation, set the following options:

Procedure

Specify the IAM user name and select Programmatic access.
Attach the AdministratorAccess policy to ensure that the account has sufficient permission to create the cluster. This policy provides the cluster with the ability to grant credentials to each OpenShift Container Platform component. The cluster grants the components only the credentials that they require.
注意
While it is possible to create a policy that grants the all of the required AWS permissions and attach it to the user, this is not the preferred option. The cluster will not have the ability to grant additional credentials to individual components, so the same credentials are used by all components.
Optional: Add metadata to the user by attaching tags.
Confirm that the user name that you specified is granted the AdministratorAccess policy.
Record the access key ID and secret access key values. You must use these values when you configure your local machine to run the installation program.
重要
You cannot use a temporary session token that you generated while using a multi-factor authentication device to authenticate to AWS when you deploy a cluster. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use key-based, long-lived credentials.

2.1.5. Supported AWS regions

You can deploy an OpenShift Container Platform cluster to the following regions:

ap-northeast-1 (Tokyo)
ap-northeast-2 (Seoul)
ap-south-1 (Mumbai)
ap-southeast-1 (Singapore)
ap-southeast-2 (Sydney)
ca-central-1 (Central)
eu-central-1 (Frankfurt)

2.1.6. Next steps

Install an OpenShift Container Platform cluster:
- Quickly install a cluster with default options on installer-provisioned infrastructure
- Install a cluster with cloud customizations on installer-provisioned infrastructure
- Install a cluster with network customizations on installer-provisioned infrastructure
- Installing a cluster on user-provisioned infrastructure in AWS by using CloudFormation templates

2.2. Manually creating IAM for AWS

2.2.1. Manually create IAM

The Cloud Credential Operator can be put into manual mode prior to installation in environments where the cloud identity and access management (IAM) APIs are not reachable, or the administrator prefers not to store an administrator-level credential secret in the cluster kube-system namespace.

Procedure

Run the OpenShift Container Platform installer to generate manifests:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
openshift-install create manifests --dir=mycluster
```
```
$ openshift-install create manifests --dir=mycluster
```

Insert a config map into the manifests directory so that the Cloud Credential Operator is placed in manual mode:

Copy to Clipboard Toggle word wrap

cat <<EOF > mycluster/manifests/cco-configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: cloud-credential-operator-config
  namespace: openshift-cloud-credential-operator
  annotations:
    release.openshift.io/create-only: "true"
data:
  disabled: "true"
EOF

$ cat <<EOF > mycluster/manifests/cco-configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: cloud-credential-operator-config
  namespace: openshift-cloud-credential-operator
  annotations:
    release.openshift.io/create-only: "true"
data:
  disabled: "true"
EOF

Remove the admin credential secret created using your local cloud credentials. This removal prevents your admin credential from being stored in the cluster:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm mycluster/openshift/99_cloud-creds-secret.yaml
```
```
$ rm mycluster/openshift/99_cloud-creds-secret.yaml
```
Obtain the OpenShift Container Platform release image your openshift-install binary is built to use:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
bin/openshift-install version
```
```
$ bin/openshift-install version
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
release image quay.io/openshift-release-dev/ocp-release:4.z.z-x86_64
```
```
release image quay.io/openshift-release-dev/ocp-release:4.z.z-x86_64
```

Locate all CredentialsRequest objects in this release image that target the cloud you are deploying on:

Copy to Clipboard Toggle word wrap

oc adm release extract quay.io/openshift-release-dev/ocp-release:4.z.z-x86_64 --to ./release-image

$ oc adm release extract quay.io/openshift-release-dev/ocp-release:4.z.z-x86_64 --to ./release-image

Locate the CredentialsRequests in the extracted file:

Copy to Clipboard Toggle word wrap

grep -l "apiVersion: cloudcredential.openshift.io" * | xargs cat

$ grep -l "apiVersion: cloudcredential.openshift.io" * | xargs cat

注意

In a future OpenShift Container Platform release, there will be a new oc adm release command to scan for the CredentialsRequests and display them.

This displays the details for each request. Remember to ignore any CredentialsRequests where the spec.providerSpec.kind does not match the cloud provider you are installing to.

Sample CredentialsRequest object

Copy to Clipboard Toggle word wrap

apiVersion: cloudcredential.openshift.io/v1
kind: CredentialsRequest
metadata:
  name: cloud-credential-operator-iam-ro
  namespace: openshift-cloud-credential-operator
spec:

    name: cloud-credential-operator-iam-ro-creds
    namespace: openshift-cloud-credential-operator
  providerSpec:
    apiVersion: cloudcredential.openshift.io/v1
    kind: AWSProviderSpec
    statementEntries:
    - effect: Allow
      action:
      - iam:GetUser
      - iam:GetUserPolicy
      - iam:ListAccessKeys
      resource: "*"

apiVersion: cloudcredential.openshift.io/v1
kind: CredentialsRequest
metadata:
  name: cloud-credential-operator-iam-ro
  namespace: openshift-cloud-credential-operator
spec:
  secretRef:
    name: cloud-credential-operator-iam-ro-creds
    namespace: openshift-cloud-credential-operator
  providerSpec:
    apiVersion: cloudcredential.openshift.io/v1
    kind: AWSProviderSpec
    statementEntries:
    - effect: Allow
      action:
      - iam:GetUser
      - iam:GetUserPolicy
      - iam:ListAccessKeys
      resource: "*"

Create YAML files for secrets in the openshift-install manifests directory that you generated previously. The secrets must be stored using the namespace and secret name defined in each request.spec.secretRef. The format for the secret data varies for each cloud provider.
Proceed with cluster creation:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
openshift-install create cluster --dir=mycluster
```
```
$ openshift-install create cluster --dir=mycluster
```
重要
Before performing an upgrade, you might need to adjust your credentials if permissions have changed in the next release. In the future, the Cloud Credential Operator might prevent you from upgrading until you have indicated that you have addressed updated permissions.

2.2.2. Admin credentials root secret format

Each cloud provider uses a credentials root secret in the kube-system namespace by convention, which is then used to satisfy all credentials requests and create their respective secrets. This is done either by minting new credentials, Mint Mode, or by copying the credentials root secret, Passthrough Mode.

The format for the secret varies by cloud, and is also used for each CredentialsRequest secret.

Amazon Web Services (AWS) secret format

Copy to Clipboard Toggle word wrap

apiVersion: v1
kind: Secret
metadata:
  namespace: kube-system
  name: aws-creds
stringData:
  aws_access_key_id: <AccessKeyID>
  aws_secret_access_key: <SecretAccessKey>

apiVersion: v1
kind: Secret
metadata:
  namespace: kube-system
  name: aws-creds
stringData:
  aws_access_key_id: <AccessKeyID>
  aws_secret_access_key: <SecretAccessKey>

2.2.2.1. Upgrades

In a future release, improvements to the Cloud Credential Operator will prevent situations where a user might enter an upgrade that will fail because their manually maintained credentials have not been updated to match the CredentialsRequest objects in the upcoming release image.

2.2.3. Mint Mode

Mint Mode is supported for AWS, GCP, and Azure.

The default and recommended best practice for running OpenShift Container Platform is to run the installer with an administrator-level cloud credential. The admin credential is stored in the kube-system namespace, and then used by the Cloud Credential Operator to process the CredentialsRequest objects in the cluster and create new users for each with specific permissions.

The benefits of Mint Mode include:

Each cluster component only has the permissions it requires.
Automatic, on-going reconciliation for cloud credentials including upgrades, which might require additional credentials or permissions.

One drawback is that Mint Mode requires admin credential storage in a cluster kube-system secret.

2.2.4. Mint Mode with removal or rotation of the admin credential

Currently, this mode is only supported on AWS.

In this mode, a user installs OpenShift Container Platform with an admin credential just like the normal mint mode. However, this mode removes the admin credential secret from the cluster post-installation.

The administrator can have the Cloud Credential Operator make its own request for a read-only credential that allows it to verify if all CredentialsRequest objects have their required permissions, thus the admin credential is not required unless something needs to be changed. After the associated credential is removed, it can be destroyed on the underlying cloud, if desired.

Prior to upgrade, the admin credential should be restored. In the future, upgrade might be blocked if the credential is not present.

The admin credential is not stored in the cluster permanently.

This mode still requires the admin credential in the cluster for brief periods of time. It also requires manually re-instating the secret with admin credentials for each upgrade.

2.3. Installing a cluster quickly on AWS

In OpenShift Container Platform version 4.5, you can install a cluster on Amazon Web Services (AWS) that uses the default configuration options.

2.3.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an AWS account to host the cluster.
重要
If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use key-based, long-lived credentials. To generate appropriate keys, see Managing Access Keys for IAM Users in the AWS documentation. You can supply the keys when you run the installation program.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

2.3.2. Internet and Telemetry access for OpenShift Container Platform

In OpenShift Container Platform 4.5, you require access to the Internet to install your cluster. The Telemetry service, which runs by default to provide metrics about cluster health and the success of updates, also requires Internet access. If your cluster is connected to the Internet, Telemetry runs automatically, and your cluster is registered to the Red Hat OpenShift Cluster Manager (OCM).

Once you confirm that your Red Hat OpenShift Cluster Manager inventory is correct, either maintained automatically by Telemetry or manually using OCM, use subscription watch to track your OpenShift Container Platform subscriptions at the account or multi-cluster level.

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

If your cluster cannot have direct Internet access, you can perform a restricted network installation on some types of infrastructure that you provision. During that process, you download the content that is required and use it to populate a mirror registry with the packages that you need to install a cluster and generate the installation program. With some installation types, the environment that you install your cluster in will not require Internet access. Before you update the cluster, you update the content of the mirror registry.

2.3.3. Generating an SSH private key and adding it to the agent

If you want to perform installation debugging or disaster recovery on your cluster, you must provide an SSH key to both your ssh-agent and the installation program. You can use this key to access the bootstrap machine in a public cluster to troubleshoot installation issues.

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

2.3.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

2.3.5. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the directory name to store the files that the installation program creates.
2
To view different installation details, specify warn, debug, or error instead of info.
重要
Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
Provide values at the prompts:
1. Optional: Select an SSH key to use to access your cluster machines.
  注意
  For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
2. Select aws as the platform to target.
3. If you do not have an Amazon Web Services (AWS) profile stored on your computer, enter the AWS access key ID and secret access key for the user that you configured to run the installation program.
4. Select the AWS region to deploy the cluster to.
5. Select the base domain for the Route 53 service that you configured for your cluster.
6. Enter a descriptive name for your cluster.
7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.
Optional: Remove or disable the AdministratorAccess policy from the IAM account that you used to install the cluster.

2.3.6. Installing the CLI by downloading the binary

You can install the OpenShift CLI (oc) in order to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS.

重要

If you installed an earlier version of oc, you cannot use it to complete all of the commands in OpenShift Container Platform 4.5. Download and install the new version of oc.

$ oc <command>

2.3.7. Logging in to the cluster

You can log in to your cluster as a default system user by exporting the cluster kubeconfig file. The kubeconfig file contains information about the cluster that is used by the CLI to connect a client to the correct cluster and API server. The file is specific to a cluster and is created during OpenShift Container Platform installation.

Prerequisites

Deploy an OpenShift Container Platform cluster.
Install the oc CLI.

Procedure

Export the kubeadmin credentials:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
export KUBECONFIG=<installation_directory>/auth/kubeconfig
```
```
$ export KUBECONFIG=<installation_directory>/auth/kubeconfig 
```

```
```
system:admin
```

2.3.8. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.
If necessary, you can remove cloud provider credentials.

2.4. Installing a cluster on AWS with customizations

In OpenShift Container Platform version 4.5, you can install a customized cluster on infrastructure that the installation program provisions on Amazon Web Services (AWS). To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

2.4.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an AWS account to host the cluster.
重要
If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use long-lived credentials. To generate appropriate keys, see Managing Access Keys for IAM Users in the AWS documentation. You can supply the keys when you run the installation program.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

2.4.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

2.4.3. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.

2.4.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

2.4.5. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Amazon Web Services (AWS).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select AWS as the platform to target.
  3. If you do not have an Amazon Web Services (AWS) profile stored on your computer, enter the AWS access key ID and secret access key for the user that you configured to run the installation program.
  4. Select the AWS region to deploy the cluster to.
  5. Select the base domain for the Route 53 service that you configured for your cluster.
  6. Enter a descriptive name for your cluster.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

2.4.5.1. Installation configuration parameters

Before you deploy an OpenShift Container Platform cluster, you provide parameter values to describe your account on the cloud platform that hosts your cluster and optionally customize your cluster’s platform. When you create the install-config.yaml installation configuration file, you provide values for the required parameters through the command line. If you customize your cluster, you can modify the install-config.yaml file to provide more details about the platform.

注意

After installation, you cannot modify these parameters in the install-config.yaml file.

重要

The openshift-install command does not validate field names for parameters. If an incorrect name is specified, the related file or object is not created, and no error is reported. Ensure that the field names for any parameters that are specified are correct.

2.4.5.1.1. Required configuration parameters

Required installation configuration parameters are described in the following table:

1 9 10 13: Required. The installation program prompts you for this value.
2 6: If you do not provide these parameters and values, the installation program provides the default value.
3 7: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4 5: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.

注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.

2.4.6. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.
Optional: Remove or disable the AdministratorAccess policy from the IAM account that you used to install the cluster.

2.4.7. Installing the CLI by downloading the binary

You can install the OpenShift CLI (oc) in order to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS.

```

2.4.9. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.
If necessary, you can remove cloud provider credentials.

2.5. Installing a cluster on AWS with network customizations

In OpenShift Container Platform version 4.5, you can install a cluster on Amazon Web Services (AWS) with customized network configuration options. By customizing your network configuration, your cluster can coexist with existing IP address allocations in your environment and integrate with existing MTU and VXLAN configurations.

You must set most of the network configuration parameters during installation, and you can modify only kubeProxy configuration parameters in a running cluster.

2.5.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an AWS account to host the cluster.
重要
If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use key-based, long-lived credentials. To generate appropriate keys, see Managing Access Keys for IAM Users in the AWS documentation. You can supply the keys when you run the installation program.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

2.5.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

2.5.3. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

2.5.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

2.5.5. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Amazon Web Services (AWS).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select AWS as the platform to target.
  3. If you do not have an Amazon Web Services (AWS) profile stored on your computer, enter the AWS access key ID and secret access key for the user that you configured to run the installation program.
  4. Select the AWS region to deploy the cluster to.
  5. Select the base domain for the Route 53 service that you configured for your cluster.
  6. Enter a descriptive name for your cluster.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

2.5.6. Modifying advanced network configuration parameters

You can modify the advanced network configuration parameters only before you install the cluster. Advanced configuration customization lets you integrate your cluster into your existing network environment by specifying an MTU or VXLAN port, by allowing customization of kube-proxy settings, and by specifying a different mode for the openshiftSDNConfig parameter.

重要

Modifying the OpenShift Container Platform manifest files created by the installation program is not supported. Applying a manifest file that you create, as in the following procedure, is supported.

Prerequisites

Create the install-config.yaml file and complete any modifications to it.

Procedure

Use the following command to create manifests:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create manifests --dir=<installation_directory>
```
```
$ ./openshift-install create manifests --dir=<installation_directory> 
```

If the auto-detected value is not what you expected it to be, confirm that the MTU on the primary network interface on your nodes is correct. You cannot use this option to change the MTU value of the primary network interface on the nodes.

If your cluster requires different MTU values for different nodes, you must set this value to 50 less than the lowest MTU value in your cluster. For example, if some nodes in your cluster have an MTU of 9001, and some have an MTU of 1500, you must set this value to 1450.

5

The port to use for all VXLAN packets. The default value is 4789. If you are running in a virtualized environment with existing nodes that are part of another VXLAN network, then you might be required to change this. For example, when running an OpenShift SDN overlay on top of VMware NSX-T, you must select an alternate port for VXLAN, since both SDNs use the same default VXLAN port number.

On Amazon Web Services (AWS), you can select an alternate port for the VXLAN between port 9000 and port 9999.

2.5.8. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.
Optional: Remove or disable the AdministratorAccess policy from the IAM account that you used to install the cluster.

2.5.9. Installing the CLI by downloading the binary

You can install the OpenShift CLI (oc) in order to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS.

If necessary, you can opt out of remote health reporting.
If necessary, you can remove cloud provider credentials.

2.6. Installing a cluster on AWS in a restricted network

In OpenShift Container Platform version 4.5, you can install a cluster on Amazon Web Services (AWS) in a restricted network by creating an internal mirror of the installation release content on an existing Amazon Virtual Private Cloud (VPC).

2.6.1. Prerequisites

You mirrored the images for a disconnected installation to your registry and obtained the imageContentSources data for your version of OpenShift Container Platform.
重要
Because the installation media is on the mirror host, you can use that computer to complete all installation steps.
You have an existing VPC in AWS. When installing to a restricted network using installer-provisioned infrastructure, you cannot use the installer-provisioned VPC. You must use a user-provisioned VPC that satisfies one of the following requirements:
- Contains the mirror registry.
- Has firewall rules or a peering connection to access the mirror registry hosted elsewhere.
You reviewed details about the OpenShift Container Platform installation and update processes.
You configured an AWS account to host the cluster.
重要
If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use key-based, long-lived credentials. To generate appropriate keys, see Managing Access Keys for IAM Users in the AWS documentation. You can supply the keys when you run the installation program.
You downloaded the AWS CLI and installed it on your computer. See Install the AWS CLI Using the Bundled Installer (Linux, macOS, or Unix) in the AWS documentation.
If you use a firewall and plan to use the Telemetry service, you configured the firewall to allow the sites that your cluster requires access to.
注意
If you are configuring a proxy, be sure to also review this site list.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

2.6.2. About installations in restricted networks

In OpenShift Container Platform 4.5, you can perform an installation that does not require an active connection to the Internet to obtain software components. Restricted network installations can be completed using installer-provisioned infrastructure or user-provisioned infrastructure, depending on the cloud platform to which you are installing the cluster.

If you choose to perform a restricted network installation on a cloud platform, you still require access to its cloud APIs. Some cloud functions, like Amazon Web Service’s IAM service, require Internet access, so you might still require Internet access. Depending on your network, you might require less Internet access for an installation on bare metal hardware or on VMware vSphere.

To complete a restricted network installation, you must create a registry that mirrors the contents of the OpenShift Container Platform registry and contains the installation media. You can create this registry on a mirror host, which can access both the Internet and your closed network, or by using other methods that meet your restrictions.

2.6.2.1. Additional limits

Clusters in restricted networks have the following additional limitations and restrictions:

The ClusterVersion status includes an Unable to retrieve available updates error.
By default, you cannot use the contents of the Developer Catalog because you cannot access the required image stream tags.

2.6.3. About using a custom VPC

In OpenShift Container Platform 4.5, you can deploy a cluster into existing subnets in an existing Amazon Virtual Private Cloud (VPC) in Amazon Web Services (AWS). By deploying OpenShift Container Platform into an existing AWS VPC, you might be able to avoid limit constraints in new accounts or more easily abide by the operational constraints that your company’s guidelines set. If you cannot obtain the infrastructure creation permissions that are required to create the VPC yourself, use this installation option.

Because the installation program cannot know what other components are also in your existing subnets, it cannot choose subnet CIDRs and so forth on your behalf. You must configure networking for the subnets that you install your cluster to yourself.

2.6.3.1. Requirements for using your VPC

The installation program no longer creates the following components:

Internet gateways
NAT gateways
Subnets
Route tables
VPCs
VPC DHCP options
VPC endpoints

If you use a custom VPC, you must correctly configure it and its subnets for the installation program and the cluster to use. The installation program cannot subdivide network ranges for the cluster to use, set route tables for the subnets, or set VPC options like DHCP, so you must do so before you install the cluster.

Your VPC must meet the following characteristics:

The VPC’s CIDR block must contain the Networking.MachineCIDR range, which is the IP address pool for cluster machines.
The VPC must not use the kubernetes.io/cluster/.*: owned tag.
You must enable the enableDnsSupport and enableDnsHostnames attributes in your VPC so that the cluster can use the Route 53 zones that are attached to the VPC to resolve cluster’s internal DNS records. See DNS Support in Your VPC in the AWS documentation.

If you use a cluster with public access, you must create a public and a private subnet for each availability zone that your cluster uses.

The installation program modifies your subnets to add the kubernetes.io/cluster/.*: shared tag, so your subnets must have at least one free tag slot available for it. Review the current Tag Restrictions in the AWS documentation to ensure that the installation program can add a tag to each subnet that you specify.

If you are working in a disconnected environment, you are unable to reach the public IP addresses for EC2 and ELB endpoints. To resolve this, you must create a VPC endpoint and attach it to the subnet that the clusters are using. The endpoints should be named as follows:

ec2.<region>.amazonaws.com
elasticloadbalancing.<region>.amazonaws.com
s3.<region>.amazonaws.com

Required VPC components

You must provide a suitable VPC and subnets that allow communication to your machines.

Component	AWS type	Description
VPC	`AWS::EC2::VPC` `AWS::EC2::VPCEndpoint`	You must provide a public VPC for the cluster to use. The VPC uses an endpoint that references the route tables for each subnet to improve communication with the registry that is hosted in S3.
Public subnets	`AWS::EC2::Subnet` `AWS::EC2::SubnetNetworkAclAssociation`	Your VPC must have public subnets for between 1 and 3 availability zones and associate them with appropriate Ingress rules.
Internet gateway	`AWS::EC2::InternetGateway` `AWS::EC2::VPCGatewayAttachment` `AWS::EC2::RouteTable` `AWS::EC2::Route` `AWS::EC2::SubnetRouteTableAssociation` `AWS::EC2::NatGateway` `AWS::EC2::EIP`	You must have a public Internet gateway, with public routes, attached to the VPC. In the provided templates, each public subnet has a NAT gateway with an EIP address. These NAT gateways allow cluster resources, like private subnet instances, to reach the Internet and are not required for some restricted network or proxy scenarios.
Network access control	`AWS::EC2::NetworkAcl` `AWS::EC2::NetworkAclEntry`	You must allow the VPC to access the following ports:
		Port	Reason
		`80`	Inbound HTTP traffic
		`443`	Inbound HTTPS traffic
		`22`	Inbound SSH traffic
		`1024` - `65535`	Inbound ephemeral traffic
		`0` - `65535`	Outbound ephemeral traffic
Private subnets	`AWS::EC2::Subnet` `AWS::EC2::RouteTable` `AWS::EC2::SubnetRouteTableAssociation`	Your VPC can have private subnets. The provided CloudFormation templates can create private subnets for between 1 and 3 availability zones. If you use private subnets, you must provide appropriate routes and tables for them.

2.6.3.2. VPC validation

To ensure that the subnets that you provide are suitable, the installation program confirms the following data:

All the subnets that you specify exist.
You provide private subnets.
The subnet CIDRs belong to the machine CIDR that you specified.
You provide subnets for each availability zone. Each availability zone contains no more than one public and one private subnet. If you use a private cluster, provide only a private subnet for each availability zone. Otherwise, provide exactly one public and private subnet for each availability zone.
You provide a public subnet for each private subnet availability zone. Machines are not provisioned in availability zones that you do not provide private subnets for.

If you destroy a cluster that uses an existing VPC, the VPC is not deleted. When you remove the OpenShift Container Platform cluster from a VPC, the kubernetes.io/cluster/.*: shared tag is removed from the subnets that it used.

2.6.3.3. Division of permissions

Starting with OpenShift Container Platform 4.3, you do not need all of the permissions that are required for an installation program-provisioned infrastructure cluster to deploy a cluster. This change mimics the division of permissions that you might have at your company: some individuals can create different resource in your clouds than others. For example, you might be able to create application-specific items, like instances, buckets, and load balancers, but not networking-related components such as VPCs, subnets, or ingress rules.

The AWS credentials that you use when you create your cluster do not need the networking permissions that are required to make VPCs and core networking components within the VPC, such as subnets, routing tables, Internet gateways, NAT, and VPN. You still need permission to make the application resources that the machines within the cluster require, such as ELBs, security groups, S3 buckets, and nodes.

2.6.3.4. Isolation between clusters

If you deploy OpenShift Container Platform to an existing network, the isolation of cluster services is reduced in the following ways:

You can install multiple OpenShift Container Platform clusters in the same VPC.
ICMP ingress is allowed from the entire network.
TCP 22 ingress (SSH) is allowed to the entire network.
Control plane TCP 6443 ingress (Kubernetes API) is allowed to the entire network.
Control plane TCP 22623 ingress (MCS) is allowed to the entire network.

2.6.4. Internet and Telemetry access for OpenShift Container Platform

In OpenShift Container Platform 4.5, you require access to the Internet to obtain the images that are necessary to install your cluster. The Telemetry service, which runs by default to provide metrics about cluster health and the success of updates, also requires Internet access. If your cluster is connected to the Internet, Telemetry runs automatically, and your cluster is registered to the Red Hat OpenShift Cluster Manager (OCM).

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

Additional resources

See About remote health monitoring for more information about the Telemetry service

2.6.5. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output

```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

2.6.6. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Amazon Web Services (AWS).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster. For a restricted network installation, these files are on your bastion host.
Have the imageContentSources values that were generated during mirror registry creation.
Obtain the contents of the certificate for your mirror registry.
Retrieve a Red Hat Enterprise Linux CoreOS (RHCOS) image and upload it to an accessible location.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select AWS as the platform to target.
  3. If you do not have an Amazon Web Services (AWS) profile stored on your computer, enter the AWS access key ID and secret access key for the user that you configured to run the installation program.
  4. Select the AWS region to deploy the cluster to.
  5. Select the base domain for the Route 53 service that you configured for your cluster.
  6. Enter a descriptive name for your cluster.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Edit the install-config.yaml file to provide the additional information that is required for an installation in a restricted network.
1. Update the pullSecret value to contain the authentication information for your registry:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
pullSecret: '{"auths":{"<bastion_host_name>:5000": {"auth": "<credentials>","email": "you@example.com"}}}'
```
```
pullSecret: '{"auths":{"<bastion_host_name>:5000": {"auth": "<credentials>","email": "you@example.com"}}}'
```
  For <bastion_host_name>, specify the registry domain name that you specified in the certificate for your mirror registry, and for <credentials>, specify the base64-encoded user name and password for your mirror registry.
2. Add the additionalTrustBundle parameter and value.
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
additionalTrustBundle: |
  -----BEGIN CERTIFICATE-----
  ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
  -----END CERTIFICATE-----
```
```
additionalTrustBundle: |
  -----BEGIN CERTIFICATE-----
  ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
  -----END CERTIFICATE-----
```
  The value must be the contents of the certificate file that you used for your mirror registry, which can be an existing, trusted certificate authority or the self-signed certificate that you generated for the mirror registry.
3. Define the subnets for the VPC to install the cluster in:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
subnets:
- subnet-1
- subnet-2
- subnet-3
```
```
subnets:
- subnet-1
- subnet-2
- subnet-3
```
4. Add the image content resources, which look like this excerpt:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
imageContentSources:
- mirrors:
  - <bastion_host_name>:5000/<repo_name>/release
  source: quay.example.com/openshift-release-dev/ocp-release
- mirrors:
  - <bastion_host_name>:5000/<repo_name>/release
  source: registry.example.com/ocp/release
```
```
imageContentSources:
- mirrors:
  - <bastion_host_name>:5000/<repo_name>/release
  source: quay.example.com/openshift-release-dev/ocp-release
- mirrors:
  - <bastion_host_name>:5000/<repo_name>/release
  source: registry.example.com/ocp/release
```
  To complete these values, use the imageContentSources that you recorded during mirror registry creation.
Make any other modifications to the install-config.yaml file that you require. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

2.6.6.1. Installation configuration parameters

注意

After installation, you cannot modify these parameters in the install-config.yaml file.

重要

2.6.6.1.1. Required configuration parameters

For example, if `hostPrefix` is set to `23` then each node is assigned a `/23` subnet out of the given `cidr`. A `hostPrefix` value of `23` provides 510 (2^(32 - 23) - 2) pod IP addresses.	A subnet prefix. The default value is `23`.
`networking.serviceNetwork`	The IP address block for services. The default value is `172.30.0.0/16`. The OpenShift SDN and OVN-Kubernetes network providers support only a single IP address block for the service network.	An array with an IP address block in CIDR format. For example: Copy to Clipboard Toggle word wrap `networking: serviceNetwork: - 172.30.0.0/16`
`networking.machineNetwork`	The IP address blocks for machines. If you specify multiple IP address blocks, the blocks must not overlap.	An array of objects. For example: Copy to Clipboard Toggle word wrap `networking: machineNetwork: - cidr: 10.0.0.0/16`
`networking.machineNetwork.cidr`	Required if you use `networking.machineNetwork`. An IP address block. The default value is `10.0.0.0/16` for all platforms other than libvirt. For libvirt, the default value is `192.168.126.0/24`.	An IP network block in CIDR notation. For example, `10.0.0.0/16`. 注意 Set the `networking.machineNetwork` to match the CIDR that the preferred NIC resides in.

1 9 10: Required. The installation program prompts you for this value.
2 6: If you do not provide these parameters and values, the installation program provides the default value.
3 7: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4 5: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.
重要
If you disable simultaneous multithreading, ensure that your capacity planning accounts for the dramatically decreased machine performance. Use larger instance types, such as m4.2xlarge or m5.2xlarge, for your machines if you disable simultaneous multithreading.
8: To configure faster storage for etcd, especially for larger clusters, set the storage type as io1 and set iops to 2000.
11 14: If you provide your own VPC, specify subnets for each availability zone that your cluster uses.
12 15: Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
13: You can optionally provide the sshKey value that you use to access the machines in your cluster.
16: Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
17: You can optionally provide the sshKey value that you use to access the machines in your cluster.
18: You can optionally provide the sshKey value that you use to access the machines in your cluster.
注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
: For <local_registry>, specify the registry domain name, and optionally the port, that your mirror registry uses to serve content. For example registry.example.com or registry.example.com:5000. For <credentials>, specify the base64-encoded user name and password for your mirror registry.
: Provide the contents of the certificate file that you used for your mirror registry.
: Provide the imageContentSources section from the output of the command to mirror the repository.

2.6.6.3. Configuring the cluster-wide proxy during installation

Production environments can deny direct access to the Internet and instead have an HTTP or HTTPS proxy available. You can configure a new OpenShift Container Platform cluster to use a proxy by configuring the proxy settings in the install-config.yaml file.

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:

```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port>

```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

The installation program creates a cluster-wide proxy that is named cluster that uses the proxy settings in the provided install-config.yaml file. If no proxy settings are provided, a cluster Proxy object is still created, but it will have a nil spec.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

2.6.7. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.
Optional: Remove or disable the AdministratorAccess policy from the IAM account that you used to install the cluster.

If the mirror registry that you used to install your cluster has a trusted CA, add it to the cluster by configuring additional trust stores.
If necessary, you can opt out of remote health reporting.

2.7. Installing a cluster on AWS into an existing VPC

In OpenShift Container Platform version 4.5, you can install a cluster into an existing Amazon Virtual Private Cloud (VPC) on Amazon Web Services (AWS). The installation program provisions the rest of the required infrastructure, which you can further customize. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

2.7.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an AWS account to host the cluster.
重要
If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use long-lived credentials. To generate appropriate keys, see Managing Access Keys for IAM Users in the AWS documentation. You can supply the keys when you run the installation program.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

2.7.2. About using a custom VPC

2.7.2.1. Requirements for using your VPC

The installation program no longer creates the following components:

Internet gateways
NAT gateways
Subnets
Route tables
VPCs
VPC DHCP options
VPC endpoints

Your VPC must meet the following characteristics:

The VPC’s CIDR block must contain the Networking.MachineCIDR range, which is the IP address pool for cluster machines.
The VPC must not use the kubernetes.io/cluster/.*: owned tag.
You must enable the enableDnsSupport and enableDnsHostnames attributes in your VPC so that the cluster can use the Route 53 zones that are attached to the VPC to resolve cluster’s internal DNS records. See DNS Support in Your VPC in the AWS documentation.

If you use a cluster with public access, you must create a public and a private subnet for each availability zone that your cluster uses.

ec2.<region>.amazonaws.com
elasticloadbalancing.<region>.amazonaws.com
s3.<region>.amazonaws.com

Required VPC components

You must provide a suitable VPC and subnets that allow communication to your machines.

Component	AWS type	Description
VPC	`AWS::EC2::VPC` `AWS::EC2::VPCEndpoint`	You must provide a public VPC for the cluster to use. The VPC uses an endpoint that references the route tables for each subnet to improve communication with the registry that is hosted in S3.
Public subnets	`AWS::EC2::Subnet` `AWS::EC2::SubnetNetworkAclAssociation`	Your VPC must have public subnets for between 1 and 3 availability zones and associate them with appropriate Ingress rules.
Internet gateway	`AWS::EC2::InternetGateway` `AWS::EC2::VPCGatewayAttachment` `AWS::EC2::RouteTable` `AWS::EC2::Route` `AWS::EC2::SubnetRouteTableAssociation` `AWS::EC2::NatGateway` `AWS::EC2::EIP`	You must have a public Internet gateway, with public routes, attached to the VPC. In the provided templates, each public subnet has a NAT gateway with an EIP address. These NAT gateways allow cluster resources, like private subnet instances, to reach the Internet and are not required for some restricted network or proxy scenarios.
Network access control	`AWS::EC2::NetworkAcl` `AWS::EC2::NetworkAclEntry`	You must allow the VPC to access the following ports:
		Port	Reason
		`80`	Inbound HTTP traffic
		`443`	Inbound HTTPS traffic
		`22`	Inbound SSH traffic
		`1024` - `65535`	Inbound ephemeral traffic
		`0` - `65535`	Outbound ephemeral traffic
Private subnets	`AWS::EC2::Subnet` `AWS::EC2::RouteTable` `AWS::EC2::SubnetRouteTableAssociation`	Your VPC can have private subnets. The provided CloudFormation templates can create private subnets for between 1 and 3 availability zones. If you use private subnets, you must provide appropriate routes and tables for them.

2.7.2.2. VPC validation

To ensure that the subnets that you provide are suitable, the installation program confirms the following data:

All the subnets that you specify exist.
You provide private subnets.
The subnet CIDRs belong to the machine CIDR that you specified.
You provide subnets for each availability zone. Each availability zone contains no more than one public and one private subnet. If you use a private cluster, provide only a private subnet for each availability zone. Otherwise, provide exactly one public and private subnet for each availability zone.
You provide a public subnet for each private subnet availability zone. Machines are not provisioned in availability zones that you do not provide private subnets for.

2.7.2.3. Division of permissions

2.7.2.4. Isolation between clusters

If you deploy OpenShift Container Platform to an existing network, the isolation of cluster services is reduced in the following ways:

You can install multiple OpenShift Container Platform clusters in the same VPC.
ICMP ingress is allowed from the entire network.
TCP 22 ingress (SSH) is allowed to the entire network.
Control plane TCP 6443 ingress (Kubernetes API) is allowed to the entire network.
Control plane TCP 22623 ingress (MCS) is allowed to the entire network.

2.7.3. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

2.7.4. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

2.7.5. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

2.7.6. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Amazon Web Services (AWS).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select AWS as the platform to target.
  3. If you do not have an Amazon Web Services (AWS) profile stored on your computer, enter the AWS access key ID and secret access key for the user that you configured to run the installation program.
  4. Select the AWS region to deploy the cluster to.
  5. Select the base domain for the Route 53 service that you configured for your cluster.
  6. Enter a descriptive name for your cluster.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

1 9 10 16: Required. The installation program prompts you for this value.
2 6: If you do not provide these parameters and values, the installation program provides the default value.
3 7: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4 5: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.
重要

注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.

2.7.6.3. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```
1
```
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
```
2
```
  noProxy: example.com 
```
3
```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

2.7.7. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.
Optional: Remove or disable the AdministratorAccess policy from the IAM account that you used to install the cluster.

2.7.10. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.
If necessary, you can remove cloud provider credentials.

2.8. Installing a private cluster on AWS

In OpenShift Container Platform version 4.5, you can install a private cluster into an existing VPC on Amazon Web Services (AWS). The installation program provisions the rest of the required infrastructure, which you can further customize. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

2.8.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an AWS account to host the cluster.
重要
If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use long-lived credentials. To generate appropriate keys, see Managing Access Keys for IAM Users in the AWS documentation. You can supply the keys when you run the installation program.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

2.8.2. Private clusters

If your environment does not require an external Internet connection, you can deploy a private OpenShift Container Platform cluster that does not expose external endpoints. Private clusters are accessible from only an internal network and are not visible to the Internet.

By default, OpenShift Container Platform is provisioned to use publicly-accessible DNS and endpoints. A private cluster sets the DNS, Ingress Controller, and API server to private when you deploy your cluster. This means that the cluster resources are only accessible from your internal network and are not visible to the internet.

To deploy a private cluster, you must use existing networking that meets your requirements. Your cluster resources might be shared between other clusters on the network.

Additionally, you must deploy a private cluster from a machine that has access the API services for the cloud you provision to, the hosts on the network that you provision, and to the internet to obtain installation media. You can use any machine that meets these access requirements and follows your company’s guidelines. For example, this machine can be a bastion host on your cloud network or a machine that has access to the network through a VPN.

2.8.2.1. Private clusters in AWS

To create a private cluster on Amazon Web Services (AWS), you must provide an existing private VPC and subnets to host the cluster. The installation program must also be able to resolve the DNS records that the cluster requires. The installation program configures the Ingress Operator and API server for access from only the private network.

The cluster still requires access to Internet to access the AWS APIs.

The following items are not required or created when you install a private cluster:

Public subnets
Public load balancers, which support public ingress
A public Route 53 zone that matches the baseDomain for the cluster

The installation program does use the baseDomain that you specify to create a private Route 53 zone and the required records for the cluster. The cluster is configured so that the Operators do not create public records for the cluster and all cluster machines are placed in the private subnets that you specify.

2.8.2.1.1. Limitations

The ability to add public functionality to a private cluster is limited.

You cannot make the Kubernetes API endpoints public after installation without taking additional actions, including creating public subnets in the VPC for each availability zone in use, creating a public load balancer, and configuring the control plane security groups to allow traffic from Internet on 6443 (Kubernetes API port).
If you use a public Service type load balancer, you must tag a public subnet in each availability zone with kubernetes.io/cluster/<cluster-infra-id>: shared so that AWS can use them to create public load balancers.

2.8.3. About using a custom VPC

2.8.3.1. Requirements for using your VPC

The installation program no longer creates the following components:

Internet gateways
NAT gateways
Subnets
Route tables
VPCs
VPC DHCP options
VPC endpoints

Your VPC must meet the following characteristics:

The VPC’s CIDR block must contain the Networking.MachineCIDR range, which is the IP address pool for cluster machines.
The VPC must not use the kubernetes.io/cluster/.*: owned tag.
You must enable the enableDnsSupport and enableDnsHostnames attributes in your VPC so that the cluster can use the Route 53 zones that are attached to the VPC to resolve cluster’s internal DNS records. See DNS Support in Your VPC in the AWS documentation.

If you use a cluster with public access, you must create a public and a private subnet for each availability zone that your cluster uses.

ec2.<region>.amazonaws.com
elasticloadbalancing.<region>.amazonaws.com
s3.<region>.amazonaws.com

Required VPC components

You must provide a suitable VPC and subnets that allow communication to your machines.

Component	AWS type	Description
VPC	`AWS::EC2::VPC` `AWS::EC2::VPCEndpoint`	You must provide a public VPC for the cluster to use. The VPC uses an endpoint that references the route tables for each subnet to improve communication with the registry that is hosted in S3.
Public subnets	`AWS::EC2::Subnet` `AWS::EC2::SubnetNetworkAclAssociation`	Your VPC must have public subnets for between 1 and 3 availability zones and associate them with appropriate Ingress rules.
Internet gateway	`AWS::EC2::InternetGateway` `AWS::EC2::VPCGatewayAttachment` `AWS::EC2::RouteTable` `AWS::EC2::Route` `AWS::EC2::SubnetRouteTableAssociation` `AWS::EC2::NatGateway` `AWS::EC2::EIP`	You must have a public Internet gateway, with public routes, attached to the VPC. In the provided templates, each public subnet has a NAT gateway with an EIP address. These NAT gateways allow cluster resources, like private subnet instances, to reach the Internet and are not required for some restricted network or proxy scenarios.
Network access control	`AWS::EC2::NetworkAcl` `AWS::EC2::NetworkAclEntry`	You must allow the VPC to access the following ports:
		Port	Reason
		`80`	Inbound HTTP traffic
		`443`	Inbound HTTPS traffic
		`22`	Inbound SSH traffic
		`1024` - `65535`	Inbound ephemeral traffic
		`0` - `65535`	Outbound ephemeral traffic
Private subnets	`AWS::EC2::Subnet` `AWS::EC2::RouteTable` `AWS::EC2::SubnetRouteTableAssociation`	Your VPC can have private subnets. The provided CloudFormation templates can create private subnets for between 1 and 3 availability zones. If you use private subnets, you must provide appropriate routes and tables for them.

2.8.3.2. VPC validation

To ensure that the subnets that you provide are suitable, the installation program confirms the following data:

All the subnets that you specify exist.
You provide private subnets.
The subnet CIDRs belong to the machine CIDR that you specified.
You provide subnets for each availability zone. Each availability zone contains no more than one public and one private subnet. If you use a private cluster, provide only a private subnet for each availability zone. Otherwise, provide exactly one public and private subnet for each availability zone.
You provide a public subnet for each private subnet availability zone. Machines are not provisioned in availability zones that you do not provide private subnets for.

2.8.3.3. Division of permissions

2.8.3.4. Isolation between clusters

If you deploy OpenShift Container Platform to an existing network, the isolation of cluster services is reduced in the following ways:

You can install multiple OpenShift Container Platform clusters in the same VPC.
ICMP ingress is allowed from the entire network.
TCP 22 ingress (SSH) is allowed to the entire network.
Control plane TCP 6443 ingress (Kubernetes API) is allowed to the entire network.
Control plane TCP 22623 ingress (MCS) is allowed to the entire network.

2.8.4. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

2.8.5. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

2.8.6. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

2.8.7. Manually creating the installation configuration file

For installations of OpenShift Container Platform that use user-provisioned infrastructure, you manually generate your installation configuration file. For installations of a private OpenShift Container Platform cluster that are only accessible from an internal network and are not visible to the Internet, you must manually generate your installation configuration file.

Prerequisites

Obtain the OpenShift Container Platform installation program and the access token for your cluster.

Procedure

Create an installation directory to store your required installation assets in:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
mkdir <installation_directory>
```
```
$ mkdir <installation_directory>
```
重要
You must create a directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
Customize the following install-config.yaml file template and save it in the <installation_directory>.
注意
You must name this configuration file install-config.yaml.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the next step of the installation process. You must back it up now.

2.8.7.1. Installation configuration parameters

1 9 10 17: Required. The installation program prompts you for this value.
2 6: If you do not provide these parameters and values, the installation program provides the default value.
3 7: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4 5: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.
重要
If you disable simultaneous multithreading, ensure that your capacity planning accounts for the dramatically decreased machine performance. Use larger instance types, such as m4.2xlarge or m5.2xlarge, for your machines if you disable simultaneous multithreading.
8: To configure faster storage for etcd, especially for larger clusters, set the storage type as io1 and set iops to 2000.
11 14: If you provide your own VPC, specify subnets for each availability zone that your cluster uses.
12 15: Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
13: You can optionally provide the sshKey value that you use to access the machines in your cluster.
16: Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
: You can optionally provide the sshKey value that you use to access the machines in your cluster.
: You can optionally provide the sshKey value that you use to access the machines in your cluster.
注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
: How to publish the user-facing endpoints of your cluster. Set publish to Internal to deploy a private cluster, which cannot be accessed from the Internet. The default value is External.

2.8.7.3. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```
1
```
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
```
2
```
  noProxy: example.com 
```
3
```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

2.8.8. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.

2.8.9. Installing the CLI by downloading the binary

You can install the OpenShift CLI (oc) in order to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS.

重要

2.8.11. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.
If necessary, you can remove cloud provider credentials.

2.9. Installing a cluster on user-provisioned infrastructure in AWS by using CloudFormation templates

In OpenShift Container Platform version 4.5, you can install a cluster on Amazon Web Services (AWS) that uses infrastructure that you provide.

One way to create this infrastructure is to use the provided CloudFormation templates. You can modify the templates to customize your infrastructure or use the information that they contain to create AWS objects according to your company’s policies.

重要

The steps for performing a user-provisioned infrastructure installation are provided as an example only. Installing a cluster with infrastructure you provide requires knowledge of the cloud provider and the installation process of OpenShift Container Platform. Several CloudFormation templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods; the templates are just an example.

2.9.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an AWS account to host the cluster.
重要
If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use key-based, long-lived credentials. To generate appropriate keys, see Managing Access Keys for IAM Users in the AWS documentation. You can supply the keys when you run the installation program.
Download the AWS CLI and install it on your computer. See Install the AWS CLI Using the Bundled Installer (Linux, macOS, or Unix) in the AWS documentation.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
注意
Be sure to also review this site list if you are configuring a proxy.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

2.9.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

2.9.3. Required AWS infrastructure components

To install OpenShift Container Platform on user-provisioned infrastructure in Amazon Web Services (AWS), you must manually create both the machines and their supporting infrastructure.

For more information about the integration testing for different platforms, see the OpenShift Container Platform 4.x Tested Integrations page.

You can use the provided Cloud Formation templates to create this infrastructure, you can manually create the components, or you can reuse existing infrastructure that meets the cluster requirements. Review the Cloud Formation templates for more details about how the components interrelate.

2.9.3.1. Cluster machines

You need AWS::EC2::Instance objects for the following machines:

A bootstrap machine. This machine is required during installation, but you can remove it after your cluster deploys.
Three control plane machines. The control plane machines are not governed by a machine set.
Compute machines. You must create at least two compute machines, which are also known as worker machines, during installation. These machines are not governed by a machine set.

You can use the following instance types for the cluster machines with the provided Cloud Formation templates.

重要

If m4 instance types are not available in your region, such as with eu-west-3, use m5 types instead.

表 2.22. Instance types for machines
Instance type	Bootstrap	Control plane	Compute
`i3.large`	x
`m4.large` or `m5.large`			x
`m4.xlarge` or `m5.xlarge`		x	x
`m4.2xlarge`		x	x
`m4.4xlarge`		x	x
`m4.8xlarge`		x	x
`m4.10xlarge`		x	x
`m4.16xlarge`		x	x
`c4.large`			x
`c4.xlarge`			x
`c4.2xlarge`		x	x
`c4.4xlarge`		x	x
`c4.8xlarge`		x	x
`r4.large`			x
`r4.xlarge`		x	x
`r4.2xlarge`		x	x
`r4.4xlarge`		x	x
`r4.8xlarge`		x	x
`r4.16xlarge`		x	x

You might be able to use other instance types that meet the specifications of these instance types.

2.9.3.2. Certificate signing requests management

Because your cluster has limited access to automatic machine management when you use infrastructure that you provision, you must provide a mechanism for approving cluster certificate signing requests (CSRs) after installation. The kube-controller-manager only approves the kubelet client CSRs. The machine-approver cannot guarantee the validity of a serving certificate that is requested by using kubelet credentials because it cannot confirm that the correct machine issued the request. You must determine and implement a method of verifying the validity of the kubelet serving certificate requests and approving them.

2.9.3.3. Other infrastructure components

A VPC
DNS entries
Load balancers (classic or network) and listeners
A public and a private Route 53 zone
Security groups
IAM roles
S3 buckets

ec2.<region>.amazonaws.com
elasticloadbalancing.<region>.amazonaws.com
s3.<region>.amazonaws.com

Required VPC components

You must provide a suitable VPC and subnets that allow communication to your machines.

Component	AWS type	Description
VPC	`AWS::EC2::VPC` `AWS::EC2::VPCEndpoint`	You must provide a public VPC for the cluster to use. The VPC uses an endpoint that references the route tables for each subnet to improve communication with the registry that is hosted in S3.
Public subnets	`AWS::EC2::Subnet` `AWS::EC2::SubnetNetworkAclAssociation`	Your VPC must have public subnets for between 1 and 3 availability zones and associate them with appropriate Ingress rules.
Internet gateway	`AWS::EC2::InternetGateway` `AWS::EC2::VPCGatewayAttachment` `AWS::EC2::RouteTable` `AWS::EC2::Route` `AWS::EC2::SubnetRouteTableAssociation` `AWS::EC2::NatGateway` `AWS::EC2::EIP`	You must have a public Internet gateway, with public routes, attached to the VPC. In the provided templates, each public subnet has a NAT gateway with an EIP address. These NAT gateways allow cluster resources, like private subnet instances, to reach the Internet and are not required for some restricted network or proxy scenarios.
Network access control	`AWS::EC2::NetworkAcl` `AWS::EC2::NetworkAclEntry`	You must allow the VPC to access the following ports:
		Port	Reason
		`80`	Inbound HTTP traffic
		`443`	Inbound HTTPS traffic
		`22`	Inbound SSH traffic
		`1024` - `65535`	Inbound ephemeral traffic
		`0` - `65535`	Outbound ephemeral traffic
Private subnets	`AWS::EC2::Subnet` `AWS::EC2::RouteTable` `AWS::EC2::SubnetRouteTableAssociation`	Your VPC can have private subnets. The provided CloudFormation templates can create private subnets for between 1 and 3 availability zones. If you use private subnets, you must provide appropriate routes and tables for them.

Required DNS and load balancing components

Your DNS and load balancer configuration needs to use a public hosted zone and can use a private hosted zone similar to the one that the installation program uses if it provisions the cluster’s infrastructure. You must create a DNS entry that resolves to your load balancer. An entry for api.<cluster_name>.<domain> must point to the external load balancer, and an entry for api-int.<cluster_name>.<domain> must point to the internal load balancer.

The cluster also requires load balancers and listeners for port 6443, which are required for the Kubernetes API and its extensions, and port 22623, which are required for the Ignition config files for new machines. The targets will be the master nodes. Port 6443 must be accessible to both clients external to the cluster and nodes within the cluster. Port 22623 must be accessible to nodes within the cluster.

Component	AWS type	Description
DNS	`AWS::Route53::HostedZone`	The hosted zone for your internal DNS.
etcd record sets	`AWS::Route53::RecordSet`	The registration records for etcd for your control plane machines.
Public load balancer	`AWS::ElasticLoadBalancingV2::LoadBalancer`	The load balancer for your public subnets.
External API server record	`AWS::Route53::RecordSetGroup`	Alias records for the external API server.
External listener	`AWS::ElasticLoadBalancingV2::Listener`	A listener on port 6443 for the external load balancer.
External target group	`AWS::ElasticLoadBalancingV2::TargetGroup`	The target group for the external load balancer.
Private load balancer	`AWS::ElasticLoadBalancingV2::LoadBalancer`	The load balancer for your private subnets.
Internal API server record	`AWS::Route53::RecordSetGroup`	Alias records for the internal API server.
Internal listener	`AWS::ElasticLoadBalancingV2::Listener`	A listener on port 22623 for the internal load balancer.
Internal target group	`AWS::ElasticLoadBalancingV2::TargetGroup`	The target group for the internal load balancer.
Internal listener	`AWS::ElasticLoadBalancingV2::Listener`	A listener on port 6443 for the internal load balancer.
Internal target group	`AWS::ElasticLoadBalancingV2::TargetGroup`	The target group for the internal load balancer.

Security groups

The control plane and worker machines require access to the following ports:

Group	Type	IP Protocol	Port range
`MasterSecurityGroup`	`AWS::EC2::SecurityGroup`	`icmp`	`0`
		`tcp`	`22`
		`tcp`	`6443`
		`tcp`	`22623`
`WorkerSecurityGroup`	`AWS::EC2::SecurityGroup`	`icmp`	`0`
`WorkerSecurityGroup`	`AWS::EC2::SecurityGroup`	`tcp`	`22`
`BootstrapSecurityGroup`	`AWS::EC2::SecurityGroup`	`tcp`	`22`
`BootstrapSecurityGroup`	`AWS::EC2::SecurityGroup`	`tcp`	`19531`

Control plane Ingress

The control plane machines require the following Ingress groups. Each Ingress group is a AWS::EC2::SecurityGroupIngress resource.

Ingress group	Description	IP protocol	Port range
`MasterIngressEtcd`	etcd	`tcp`	`2379`- `2380`
`MasterIngressVxlan`	Vxlan packets	`udp`	`4789`

`WorkerIngressWorkerIngressServices`	Kubernetes Ingress services	`tcp`	`30000` - `32767`

Roles and instance profiles

You must grant the machines permissions in AWS. The provided CloudFormation templates grant the machines permission the following AWS::IAM::Role objects and provide a AWS::IAM::InstanceProfile for each set of roles. If you do not use the templates, you can grant the machines the following broad permissions or the following individual permissions.

Role	Effect	Action	Resource
Master	`Allow`	`ec2:*`	`*`
	`Allow`	`elasticloadbalancing:*`	`*`
	`Allow`	`iam:PassRole`	`*`

2.9.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

2.9.5. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program. If you install a cluster on infrastructure that you provision, you must provide this key to your cluster’s machines.

2.9.6. Creating the installation files for AWS

To install OpenShift Container Platform on Amazon Web Services (AWS) using user-provisioned infrastructure, you must generate the files that the installation program needs to deploy your cluster and modify them so that the cluster creates only the machines that it will use. You generate and customize the install-config.yaml file, Kubernetes manifests, and Ignition config files.

2.9.6.1. Creating the installation configuration file

Generate and customize the installation configuration file that the installation program needs to deploy your cluster.

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Obtain the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select aws as the platform to target.
  3. If you do not have an AWS profile stored on your computer, enter the AWS access key ID and secret access key for the user that you configured to run the installation program.
  4. Select the AWS region to deploy the cluster to.
  5. Select the base domain for the Route 53 service that you configured for your cluster.
  6. Enter a descriptive name for your cluster.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Edit the install-config.yaml file to set the number of compute replicas, which are also known as worker replicas, to 0, as shown in the following compute stanza:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
compute:
- hyperthreading: Enabled
  name: worker
  platform: {}
  replicas: 0
```
```
compute:
- hyperthreading: Enabled
  name: worker
  platform: {}
  replicas: 0
```
Optional: Back up the install-config.yaml file.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

2.9.6.2. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```
1
```
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
```
2
```
  noProxy: example.com 
```
3
```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

2.9.6.3. Creating the Kubernetes manifest and Ignition config files

Because you must modify some cluster definition files and manually start the cluster machines, you must generate the Kubernetes manifest and Ignition config files that the cluster needs to make its machines.

重要

The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.

Prerequisites

Obtain the OpenShift Container Platform installation program.
Create the install-config.yaml installation configuration file.

Procedure

Generate the Kubernetes manifests for the cluster:

Copy to Clipboard Toggle word wrap

./openshift-install create manifests --dir=<installation_directory>

$ ./openshift-install create manifests --dir=<installation_directory>

Example output

Copy to Clipboard Toggle word wrap

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

1: For <installation_directory>, specify the installation directory that contains the install-config.yaml file you created.

Because you create your own compute machines later in the installation process, you can safely ignore this warning.

Remove the Kubernetes manifest files that define the control plane machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
By removing these files, you prevent the cluster from automatically generating control plane machines.
Remove the Kubernetes manifest files that define the worker machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
Because you create and manage the worker machines yourself, you do not need to initialize these machines.
Modify the <installation_directory>/manifests/cluster-scheduler-02-config.yml Kubernetes manifest file to prevent pods from being scheduled on the control plane machines:
1. Open the <installation_directory>/manifests/cluster-scheduler-02-config.yml file.
2. Locate the mastersSchedulable parameter and set its value to False.
3. Save and exit the file.

Optional: If you do not want the Ingress Operator to create DNS records on your behalf, remove the privateZone and publicZone sections from the <installation_directory>/manifests/cluster-dns-02-config.yml DNS configuration file:

Copy to Clipboard Toggle word wrap

apiVersion: config.openshift.io/v1
kind: DNS
metadata:
  creationTimestamp: null
  name: cluster
spec:
  baseDomain: example.openshift.com
  privateZone: 
    id: mycluster-100419-private-zone
  publicZone: 
    id: example.openshift.com
status: {}

apiVersion: config.openshift.io/v1
kind: DNS
metadata:
  creationTimestamp: null
  name: cluster
spec:
  baseDomain: example.openshift.com
  privateZone:


    id: mycluster-100419-private-zone
  publicZone:


    id: example.openshift.com
status: {}

1 2: Remove this section completely.

If you do so, you must add ingress DNS records manually in a later step.

Obtain the Ignition config files:

Copy to Clipboard Toggle word wrap

./openshift-install create ignition-configs --dir=<installation_directory>

$ ./openshift-install create ignition-configs --dir=<installation_directory>

1: For <installation_directory>, specify the same installation directory.

The following files are generated in the directory:

Copy to Clipboard Toggle word wrap

.
├── auth
│   ├── kubeadmin-password
│   └── kubeconfig
├── bootstrap.ign
├── master.ign
├── metadata.json
└── worker.ign

.
├── auth
│   ├── kubeadmin-password
│   └── kubeconfig
├── bootstrap.ign
├── master.ign
├── metadata.json
└── worker.ign

2.9.7. Extracting the infrastructure name

The Ignition config files contain a unique cluster identifier that you can use to uniquely identify your cluster in Amazon Web Services (AWS). The provided CloudFormation templates contain references to this infrastructure name, so you must extract it.

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.
Generate the Ignition config files for your cluster.
Install the jq package.

Procedure

To extract and view the infrastructure name from the Ignition config file metadata, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
jq -r .infraID <installation_directory>/metadata.json
```
```
$ jq -r .infraID <installation_directory>/metadata.json 
```
1
1
For <installation_directory>, specify the path to the directory that you stored the installation files in.
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
openshift-vw9j6 
```
```
openshift-vw9j6 
```
1
1
The output of this command is your cluster name and a random string.

2.9.8. Creating a VPC in AWS

You must create a VPC in Amazon Web Services (AWS) for your OpenShift Container Platform cluster to use. You can customize the VPC to meet your requirements, including VPN and route tables. The easiest way to create the VPC is to modify the provided CloudFormation template.

注意

If you do not use the provided CloudFormation template to create your AWS infrastructure, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure an AWS account.
Generate the Ignition config files for your cluster.

Procedure

Create a JSON file that contains the parameter values that the template requires:

Copy to Clipboard Toggle word wrap

[
  {
    "ParameterKey": "VpcCidr", 
    "ParameterValue": "10.0.0.0/16" 
  },
  {
    "ParameterKey": "AvailabilityZoneCount", 
    "ParameterValue": "1" 
  },
  {
    "ParameterKey": "SubnetBits", 
    "ParameterValue": "12" 
  }
]

[
  {
    "ParameterKey": "VpcCidr",


    "ParameterValue": "10.0.0.0/16"


  },
  {
    "ParameterKey": "AvailabilityZoneCount",


    "ParameterValue": "1"


  },
  {
    "ParameterKey": "SubnetBits",


    "ParameterValue": "12"

}
]

1: The CIDR block for the VPC.
2: Specify a CIDR block in the format x.x.x.x/16-24.
3: The number of availability zones to deploy the VPC in.
4: Specify an integer between 1 and 3.
5: The size of each subnet in each availability zone.
6: Specify an integer between 5 and 13, where 5 is /27 and 13 is /19.

Copy the template from the CloudFormation template for the VPC section of this topic and save it as a YAML file on your computer. This template describes the VPC that your cluster requires.
Launch the template:
重要
You must enter the command on a single line.
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
aws cloudformation create-stack --stack-name <name>
```
```
$ aws cloudformation create-stack --stack-name <name> 
```
1
```
     --template-body file://<template>.yaml 
```
2
```
     --parameters file://<parameters>.json 
```
3
1
<name> is the name for the CloudFormation stack, such as cluster-vpc. You need the name of this stack if you remove the cluster.
2
<template> is the relative path to and name of the CloudFormation template YAML file that you saved.
3
<parameters> is the relative path to and name of the CloudFormation parameters JSON file.

Confirm that the template components exist:

Copy to Clipboard Toggle word wrap

aws cloudformation describe-stacks --stack-name <name>

$ aws cloudformation describe-stacks --stack-name <name>

After the StackStatus displays CREATE_COMPLETE, the output displays values for the following parameters. You must provide these parameter values to the other CloudFormation templates that you run to create your cluster:

`VpcId`	The ID of your VPC.
`PublicSubnetIds`	The IDs of the new public subnets.
`PrivateSubnetIds`	The IDs of the new private subnets.

2.9.8.1. CloudFormation template for the VPC

You can use the following CloudFormation template to deploy the VPC that you need for your OpenShift Container Platform cluster.

2.9.9. Creating networking and load balancing components in AWS

You must configure networking and load balancing (classic or network) in Amazon Web Services (AWS) for your OpenShift Container Platform cluster to use. The easiest way to create these components is to modify the provided CloudFormation template, which also creates a hosted zone and subnet tags.

You can run the template multiple times within a single VPC.

注意

Prerequisites

Configure an AWS account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in AWS.

Procedure

Obtain the Hosted Zone ID for the Route 53 zone that you specified in the install-config.yaml file for your cluster. You can obtain this ID from the AWS console or by running the following command:
重要
You must enter the command on a single line.

     jq --arg name "<route53_domain>." \ 
```
1
```
     -r '.HostedZones | .[] | select(.Name=="\($name)") | .Id'
```

For the <route53_domain>, specify the Route 53 base domain that you used when you generated the install-config.yaml file for the cluster.
Create a JSON file that contains the parameter values that the template requires:

2.9.12. Creating the bootstrap node in AWS

You must create the bootstrap node in Amazon Web Services (AWS) to use during OpenShift Container Platform cluster initialization. The easiest way to create this node is to modify the provided CloudFormation template.

注意

If you do not use the provided CloudFormation template to create your bootstrap node, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure an AWS account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in AWS.
Create and configure DNS, load balancers, and listeners in AWS.
Create control plane and compute roles.

Procedure

Provide a location to serve the bootstrap.ign Ignition config file to your cluster. This file is located in your installation directory. One way to do this is to create an S3 bucket in your cluster’s region and upload the Ignition config file to it.
重要
The provided CloudFormation Template assumes that the Ignition config files for your cluster are served from an S3 bucket. If you choose to serve the files from another location, you must modify the templates.
注意
The bootstrap Ignition config file does contain secrets, like X.509 keys. The following steps provide basic security for the S3 bucket. To provide additional security, you can enable an S3 bucket policy to allow only certain users, such as the OpenShift IAM user, to access objects that the bucket contains. You can avoid S3 entirely and serve your bootstrap Ignition config file from any address that the bootstrap machine can reach.
1. Create the bucket:

```
```
$ aws s3 mb s3://<cluster-name>-infra 
```

  <cluster-name>-infra is the bucket name.
2. Upload the bootstrap.ign Ignition config file to the bucket:

```
aws s3 cp bootstrap.ign s3://<cluster-name>-infra/bootstrap.ign
```
```
$ aws s3 cp bootstrap.ign s3://<cluster-name>-infra/bootstrap.ign
```
3. Verify that the file uploaded:

2.9.13. Creating the control plane machines in AWS

You must create the control plane machines in Amazon Web Services (AWS) for your cluster to use. The easiest way to create these nodes is to modify the provided CloudFormation template.

注意

If you do not use the provided CloudFormation template to create your control plane nodes, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure an AWS account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in AWS.
Create and configure DNS, load balancers, and listeners in AWS.
Create control plane and compute roles.
Create the bootstrap machine.

Procedure

Create a JSON file that contains the parameter values that the template requires:

2.9.14. Initializing the bootstrap node on AWS with user-provisioned infrastructure

After you create all of the required infrastructure in Amazon Web Services (AWS), you can install the cluster.

Prerequisites

Configure an AWS account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in AWS.
Create and configure DNS, load balancers, and listeners in AWS.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.
If you plan to manually manage the worker machines, create the worker machines.

Procedure

Change to the directory that contains the installation program and run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install wait-for bootstrap-complete --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install wait-for bootstrap-complete --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the path to the directory that you stored the installation files in.
2
To view different installation details, specify warn, debug, or error instead of info.
If the command exits without a FATAL warning, your production control plane has initialized.

2.9.14.1. Creating the worker nodes in AWS

You can create worker nodes in Amazon Web Services (AWS) for your cluster to use. The easiest way to manually create these nodes is to modify the provided CloudFormation template.

重要

The CloudFormation template creates a stack that represents one worker machine. You must create a stack for each worker machine.

注意

If you do not use the provided CloudFormation template to create your worker nodes, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure an AWS account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in AWS.
Create and configure DNS, load balancers, and listeners in AWS.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.

Procedure

Create a JSON file that contains the parameter values that the CloudFormation template requires:

Continue to create worker stacks until you have created enough worker machines for your cluster.
重要
You must create at least two worker machines, so you must create at least two stacks that use this CloudFormation template.

2.9.17. Approving the certificate signing requests for your machines

When you add machines to a cluster, two pending certificate signing requests (CSRs) are generated for each machine that you added. You must confirm that these CSRs are approved or, if necessary, approve them yourself. The client requests must be approved first, followed by the server requests.

Prerequisites

You added machines to your cluster.

Procedure

Confirm that the cluster recognizes the machines:

Copy to Clipboard Toggle word wrap

oc get nodes

$ oc get nodes

Example output

Copy to Clipboard Toggle word wrap

NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  63m  v1.18.3
master-1  Ready     master  63m  v1.18.3
master-2  Ready     master  64m  v1.18.3
worker-0  NotReady  worker  76s  v1.18.3
worker-1  NotReady  worker  70s  v1.18.3

NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  63m  v1.18.3
master-1  Ready     master  63m  v1.18.3
master-2  Ready     master  64m  v1.18.3
worker-0  NotReady  worker  76s  v1.18.3
worker-1  NotReady  worker  70s  v1.18.3

The output lists all of the machines that you created.

Review the pending CSRs and ensure that you see the client requests with the Pending or Approved status for each machine that you added to the cluster:

Copy to Clipboard Toggle word wrap

oc get csr

$ oc get csr

Example output

Copy to Clipboard Toggle word wrap

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-8b2br   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-8b2br   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

In this example, two machines are joining the cluster. You might see more approved CSRs in the list.

If the CSRs were not approved, after all of the pending CSRs for the machines you added are in Pending status, approve the CSRs for your cluster machines:
注意
Because the CSRs rotate automatically, approve your CSRs within an hour of adding the machines to the cluster. If you do not approve them within an hour, the certificates will rotate, and more than two certificates will be present for each node. You must approve all of these certificates. Once the client CSR is approved, the Kubelet creates a secondary CSR for the serving certificate, which requires manual approval. Then, subsequent serving certificate renewal requests are automatically approved by the machine-approver if the Kubelet requests a new certificate with identical parameters.
- To approve them individually, run the following command for each valid CSR:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm certificate approve <csr_name>
```
```
$ oc adm certificate approve <csr_name> 
```
  1
  1
  <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```
```
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```

Now that your client requests are approved, you must review the server requests for each machine that you added to the cluster:

Copy to Clipboard Toggle word wrap

oc get csr

$ oc get csr

Example output

Copy to Clipboard Toggle word wrap

NAME        AGE     REQUESTOR                                                                   CONDITION

csr-c57lv   5m26s   system:node:ip-10-0-95-157.us-east-2.compute.internal                       Pending
...

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-bfd72   5m26s   system:node:ip-10-0-50-126.us-east-2.compute.internal                       Pending

...

If the remaining CSRs are not approved, and are in the Pending status, approve the CSRs for your cluster machines:
- To approve them individually, run the following command for each valid CSR:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm certificate approve <csr_name>
```
```
$ oc adm certificate approve <csr_name> 
```
  1
  1
  <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve
```
```
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve
```

After all client and server CSRs have been approved, the machines have the Ready status. Verify this by running the following command:

Copy to Clipboard Toggle word wrap

oc get nodes

$ oc get nodes

Example output

Copy to Clipboard Toggle word wrap

NAME      STATUS    ROLES   AGE  VERSION

worker-0  Ready     worker  11m  v1.20.0
worker-1  Ready     worker  11m  v1.20.0

注意

It can take a few minutes after approval of the server CSRs for the machines to transition to the Ready status.

Configure the Operators that are not available.

2.9.18.1. Image registry storage configuration

Amazon Web Services provides default storage, which means the Image Registry Operator is available after installation. However, if the Registry Operator cannot create an S3 bucket and automatically configure storage, you must manually configure registry storage.

Instructions are shown for configuring a persistent volume, which is required for production clusters. Where applicable, instructions are shown for configuring an empty directory as the storage location, which is available for only non-production clusters.

Additional instructions are provided for allowing the image registry to use block storage types by using the Recreate rollout strategy during upgrades.

You can configure registry storage for user-provisioned infrastructure in AWS to deploy OpenShift Container Platform to hidden regions. See Configuring the registry for AWS user-provisioned infrastructure for more information.

2.9.18.1.1. Configuring registry storage for AWS with user-provisioned infrastructure

During installation, your cloud credentials are sufficient to create an Amazon S3 bucket and the Registry Operator will automatically configure storage.

If the Registry Operator cannot create an S3 bucket and automatically configure storage, you can create an S3 bucket and configure storage with the following procedure.

Prerequisites

A cluster on AWS with user-provisioned infrastructure.
For Amazon S3 storage, the secret is expected to contain two keys:
- REGISTRY_STORAGE_S3_ACCESSKEY
- REGISTRY_STORAGE_S3_SECRETKEY

Procedure

Use the following procedure if the Registry Operator cannot create an S3 bucket and automatically configure storage.

Set up a Bucket Lifecycle Policy to abort incomplete multipart uploads that are one day old.

Fill in the storage configuration in configs.imageregistry.operator.openshift.io/cluster:

Copy to Clipboard Toggle word wrap

oc edit configs.imageregistry.operator.openshift.io/cluster

$ oc edit configs.imageregistry.operator.openshift.io/cluster

Example configuration

Copy to Clipboard Toggle word wrap

storage:
  s3:
    bucket: <bucket-name>
    region: <region-name>

storage:
  s3:
    bucket: <bucket-name>
    region: <region-name>

警告

To secure your registry images in AWS, block public access to the S3 bucket.

2.9.18.1.2. Configuring storage for the image registry in non-production clusters

You must configure storage for the Image Registry Operator. For non-production clusters, you can set the image registry to an empty directory. If you do so, all images are lost if you restart the registry.

Procedure

To set the image registry storage to an empty directory:

Copy to Clipboard Toggle word wrap

oc patch configs.imageregistry.operator.openshift.io cluster --type merge --patch '{"spec":{"storage":{"emptyDir":{}}}}'

$ oc patch configs.imageregistry.operator.openshift.io cluster --type merge --patch '{"spec":{"storage":{"emptyDir":{}}}}'

警告

Configure this option for only non-production clusters.

If you run this command before the Image Registry Operator initializes its components, the oc patch command fails with the following error:

Copy to Clipboard Toggle word wrap

Error from server (NotFound): configs.imageregistry.operator.openshift.io "cluster" not found

Error from server (NotFound): configs.imageregistry.operator.openshift.io "cluster" not found

Wait a few minutes and run the command again.

Ensure that your registry is set to managed to enable building and pushing of images.
- Run:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc edit configs.imageregistry/cluster
```
```
$ oc edit configs.imageregistry/cluster
```
  Then, change the line
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow

managementState: Removed
```
```
managementState: Removed
```
  to
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
managementState: Managed
```
```
managementState: Managed
```

2.9.19. Deleting the bootstrap resources

After you complete the initial Operator configuration for the cluster, remove the bootstrap resources from Amazon Web Services (AWS).

Prerequisites

You completed the initial Operator configuration for your cluster.

Procedure

Delete the bootstrap resources. If you used the CloudFormation template, delete its stack:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
aws cloudformation delete-stack --stack-name <name>
```
```
$ aws cloudformation delete-stack --stack-name <name> 
```
1
1
<name> is the name of your bootstrap stack.

2.9.20. Creating the Ingress DNS Records

If you removed the DNS Zone configuration, manually create DNS records that point to the Ingress load balancer. You can create either a wildcard record or specific records. While the following procedure uses A records, you can use other record types that you require, such as CNAME or alias.

Prerequisites

You deployed an OpenShift Container Platform cluster on Amazon Web Services (AWS) that uses infrastructure that you provisioned.
Install the OpenShift CLI (oc).
Install the jq package.
Download the AWS CLI and install it on your computer. See Install the AWS CLI Using the Bundled Installer (Linux, macOS, or Unix).

Procedure

Determine the routes to create.

To create a wildcard record, use *.apps.<cluster_name>.<domain_name>, where <cluster_name> is your cluster name, and <domain_name> is the Route 53 base domain for your OpenShift Container Platform cluster.

To create specific records, you must create a record for each route that your cluster uses, as shown in the output of the following command:

Copy to Clipboard Toggle word wrap

oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

$ oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

Example output

2: For <cluster_domain>, specify the domain or subdomain that you use with your OpenShift Container Platform cluster.
3: For <hosted_zone_id>, specify the public hosted zone ID for the load balancer that you obtained.
4: For <external_ip>, specify the value of the external IP address of the Ingress Operator load balancer. Ensure that you include the trailing period (.) in this parameter value.

2.9.21. Completing an AWS installation on user-provisioned infrastructure

After you start the OpenShift Container Platform installation on Amazon Web Service (AWS) user-provisioned infrastructure, monitor the deployment to completion.

Prerequisites

Removed the bootstrap node for an OpenShift Container Platform cluster on user-provisioned AWS infrastructure.
Install the oc CLI and log in.

Procedure

Complete the cluster installation:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install --dir=<installation_directory> wait-for install-complete
```
```
$ ./openshift-install --dir=<installation_directory> wait-for install-complete 
```
1
1
For <installation_directory>, specify the path to the directory that you stored the installation files in.
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
INFO Waiting up to 30m0s for the cluster to initialize...
```
```
INFO Waiting up to 30m0s for the cluster to initialize...
```
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.

2.9.22. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.
If necessary, you can remove cloud provider credentials.

2.10. Installing a cluster on AWS in a restricted network with user-provisioned infrastructure

In OpenShift Container Platform version 4.5, you can install a cluster on Amazon Web Services (AWS) using infrastructure that you provide and an internal mirror of the installation release content.

重要

While you can install an OpenShift Container Platform cluster by using mirrored installation release content, your cluster still requires Internet access to use the AWS APIs.

重要

2.10.1. Prerequisites

You created a mirror registry on your mirror host and obtained the imageContentSources data for your version of OpenShift Container Platform.
重要
Because the installation media is on the mirror host, you can use that computer to complete all installation steps.
Review details about the OpenShift Container Platform installation and update processes.
Configure an AWS account to host the cluster.
重要
If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use key-based, long-lived credentials. To generate appropriate keys, see Managing Access Keys for IAM Users in the AWS documentation. You can supply the keys when you run the installation program.
Download the AWS CLI and install it on your computer. See Install the AWS CLI Using the Bundled Installer (Linux, macOS, or Unix) in the AWS documentation.
If you use a firewall and plan to use telemetry, you must configure the firewall to allow the sites that your cluster requires access to.
注意
Be sure to also review this site list if you are configuring a proxy.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

2.10.2. About installations in restricted networks

重要

Because of the complexity of the configuration for user-provisioned installations, consider completing a standard user-provisioned infrastructure installation before you attempt a restricted network installation using user-provisioned infrastructure. Completing this test installation might make it easier to isolate and troubleshoot any issues that might arise during your installation in a restricted network.

2.10.2.1. Additional limits

Clusters in restricted networks have the following additional limitations and restrictions:

The ClusterVersion status includes an Unable to retrieve available updates error.
By default, you cannot use the contents of the Developer Catalog because you cannot access the required image stream tags.

2.10.3. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

2.10.4. Required AWS infrastructure components

To install OpenShift Container Platform on user-provisioned infrastructure in Amazon Web Services (AWS), you must manually create both the machines and their supporting infrastructure.

For more information about the integration testing for different platforms, see the OpenShift Container Platform 4.x Tested Integrations page.

2.10.4.1. Cluster machines

You need AWS::EC2::Instance objects for the following machines:

A bootstrap machine. This machine is required during installation, but you can remove it after your cluster deploys.
Three control plane machines. The control plane machines are not governed by a machine set.
Compute machines. You must create at least two compute machines, which are also known as worker machines, during installation. These machines are not governed by a machine set.

You can use the following instance types for the cluster machines with the provided Cloud Formation templates.

重要

If m4 instance types are not available in your region, such as with eu-west-3, use m5 types instead.

表 2.24. Instance types for machines
Instance type	Bootstrap	Control plane	Compute
`i3.large`	x
`m4.large` or `m5.large`			x
`m4.xlarge` or `m5.xlarge`		x	x
`m4.2xlarge`		x	x
`m4.4xlarge`		x	x

You might be able to use other instance types that meet the specifications of these instance types.

2.10.4.2. Certificate signing requests management

2.10.4.3. Other infrastructure components

A VPC
DNS entries
Load balancers (classic or network) and listeners
A public and a private Route 53 zone
Security groups
IAM roles
S3 buckets

ec2.<region>.amazonaws.com
elasticloadbalancing.<region>.amazonaws.com
s3.<region>.amazonaws.com

Required VPC components

You must provide a suitable VPC and subnets that allow communication to your machines.

Component	AWS type	Description
VPC	`AWS::EC2::VPC` `AWS::EC2::VPCEndpoint`	You must provide a public VPC for the cluster to use. The VPC uses an endpoint that references the route tables for each subnet to improve communication with the registry that is hosted in S3.
Public subnets	`AWS::EC2::Subnet` `AWS::EC2::SubnetNetworkAclAssociation`	Your VPC must have public subnets for between 1 and 3 availability zones and associate them with appropriate Ingress rules.

In the provided templates, each public subnet has a NAT gateway with an EIP address. These NAT gateways allow cluster resources, like private subnet instances, to reach the Internet and are not required for some restricted network or proxy scenarios.
Network access control	`AWS::EC2::NetworkAcl` `AWS::EC2::NetworkAclEntry`	You must allow the VPC to access the following ports:
		Port	Reason
		`80`	Inbound HTTP traffic
		`443`	Inbound HTTPS traffic
		`22`	Inbound SSH traffic
		`1024` - `65535`	Inbound ephemeral traffic
		`0` - `65535`	Outbound ephemeral traffic
Private subnets	`AWS::EC2::Subnet` `AWS::EC2::RouteTable` `AWS::EC2::SubnetRouteTableAssociation`	Your VPC can have private subnets. The provided CloudFormation templates can create private subnets for between 1 and 3 availability zones. If you use private subnets, you must provide appropriate routes and tables for them.

2.10.5. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program. If you install a cluster on infrastructure that you provision, you must provide this key to your cluster’s machines.

2.10.6. Creating the installation files for AWS

2.10.6.1. Creating the installation configuration file

Generate and customize the installation configuration file that the installation program needs to deploy your cluster.

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster. For a restricted network installation, these files are on your mirror host.

Procedure

Obtain the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select aws as the platform to target.
  3. If you do not have an AWS profile stored on your computer, enter the AWS access key ID and secret access key for the user that you configured to run the installation program.
  4. Select the AWS region to deploy the cluster to.
  5. Select the base domain for the Route 53 service that you configured for your cluster.
  6. Enter a descriptive name for your cluster.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Edit the install-config.yaml file to set the number of compute replicas, which are also known as worker replicas, to 0, as shown in the following compute stanza:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
compute:
- hyperthreading: Enabled
  name: worker
  platform: {}
  replicas: 0
```
```
compute:
- hyperthreading: Enabled
  name: worker
  platform: {}
  replicas: 0
```
Edit the install-config.yaml file to provide the additional information that is required for an installation in a restricted network.
1. Update the pullSecret value to contain the authentication information for your registry:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
pullSecret: '{"auths":{"<local_registry>": {"auth": "<credentials>","email": "you@example.com"}}}'
```
```
pullSecret: '{"auths":{"<local_registry>": {"auth": "<credentials>","email": "you@example.com"}}}'
```
  For <local_registry>, specify the registry domain name, and optionally the port, that your mirror registry uses to serve content. For example registry.example.com or registry.example.com:5000. For <credentials>, specify the base64-encoded user name and password for your mirror registry.
2. Add the additionalTrustBundle parameter and value. The value must be the contents of the certificate file that you used for your mirror registry, which can be an exiting, trusted certificate authority or the self-signed certificate that you generated for the mirror registry.
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
additionalTrustBundle: |
  -----BEGIN CERTIFICATE-----
  ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
  -----END CERTIFICATE-----
```
```
additionalTrustBundle: |
  -----BEGIN CERTIFICATE-----
  ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
  -----END CERTIFICATE-----
```
3. Add the image content resources:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
imageContentSources:
- mirrors:
  - <local_registry>/<local_repository_name>/release
  source: quay.io/openshift-release-dev/ocp-release
- mirrors:
  - <local_registry>/<local_repository_name>/release
  source: quay.io/openshift-release-dev/ocp-v4.0-art-dev
```
```
imageContentSources:
- mirrors:
  - <local_registry>/<local_repository_name>/release
  source: quay.io/openshift-release-dev/ocp-release
- mirrors:
  - <local_registry>/<local_repository_name>/release
  source: quay.io/openshift-release-dev/ocp-v4.0-art-dev
```
  Use the imageContentSources section from the output of the command to mirror the repository or the values that you used when you mirrored the content from the media that you brought into your restricted network.
4. Optional: Set the publishing strategy to Internal:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
publish: Internal
```
```
publish: Internal
```
  By setting this option, you create an internal Ingress Controller and a private load balancer.
Optional: Back up the install-config.yaml file.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

2.10.6.2. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```
1
```
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
```
2
```
  noProxy: example.com 
```
3
```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

2.10.6.3. Creating the Kubernetes manifest and Ignition config files

重要

Prerequisites

Obtain the OpenShift Container Platform installation program. For a restricted network installation, these files are on your mirror host.
Create the install-config.yaml installation configuration file.

Procedure

Generate the Kubernetes manifests for the cluster:

Copy to Clipboard Toggle word wrap

./openshift-install create manifests --dir=<installation_directory>

$ ./openshift-install create manifests --dir=<installation_directory>

Example output

Copy to Clipboard Toggle word wrap

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

1: For <installation_directory>, specify the installation directory that contains the install-config.yaml file you created.

Because you create your own compute machines later in the installation process, you can safely ignore this warning.

Remove the Kubernetes manifest files that define the control plane machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
By removing these files, you prevent the cluster from automatically generating control plane machines.
Remove the Kubernetes manifest files that define the worker machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
Because you create and manage the worker machines yourself, you do not need to initialize these machines.
Modify the <installation_directory>/manifests/cluster-scheduler-02-config.yml Kubernetes manifest file to prevent pods from being scheduled on the control plane machines:
1. Open the <installation_directory>/manifests/cluster-scheduler-02-config.yml file.
2. Locate the mastersSchedulable parameter and set its value to False.
3. Save and exit the file.

2.10.12. Creating the bootstrap node in AWS

注意

Prerequisites

Configure an AWS account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in AWS.
Create and configure DNS, load balancers, and listeners in AWS.
Create control plane and compute roles.

Procedure

Provide a location to serve the bootstrap.ign Ignition config file to your cluster. This file is located in your installation directory. One way to do this is to create an S3 bucket in your cluster’s region and upload the Ignition config file to it.
重要
The provided CloudFormation Template assumes that the Ignition config files for your cluster are served from an S3 bucket. If you choose to serve the files from another location, you must modify the templates.
注意
The bootstrap Ignition config file does contain secrets, like X.509 keys. The following steps provide basic security for the S3 bucket. To provide additional security, you can enable an S3 bucket policy to allow only certain users, such as the OpenShift IAM user, to access objects that the bucket contains. You can avoid S3 entirely and serve your bootstrap Ignition config file from any address that the bootstrap machine can reach.
1. Create the bucket:

```
aws s3 mb s3://<cluster-name>-infra
```
```
$ aws s3 mb s3://<cluster-name>-infra 
```

  <cluster-name>-infra is the bucket name.
2. Upload the bootstrap.ign Ignition config file to the bucket:

```
aws s3 cp bootstrap.ign s3://<cluster-name>-infra/bootstrap.ign
```
```
$ aws s3 cp bootstrap.ign s3://<cluster-name>-infra/bootstrap.ign
```
3. Verify that the file uploaded:

```
$ aws s3 ls s3://<cluster-name>-infra/
```

2.10.14. Initializing the bootstrap node on AWS with user-provisioned infrastructure

After you create all of the required infrastructure in Amazon Web Services (AWS), you can install the cluster.

Prerequisites

Configure an AWS account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in AWS.
Create and configure DNS, load balancers, and listeners in AWS.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.
If you plan to manually manage the worker machines, create the worker machines.

Procedure

Change to the directory that contains the installation program and run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install wait-for bootstrap-complete --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install wait-for bootstrap-complete --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the path to the directory that you stored the installation files in.
2
To view different installation details, specify warn, debug, or error instead of info.
If the command exits without a FATAL warning, your production control plane has initialized.

2.10.14.1. Creating the worker nodes in AWS

You can create worker nodes in Amazon Web Services (AWS) for your cluster to use. The easiest way to manually create these nodes is to modify the provided CloudFormation template.

重要

The CloudFormation template creates a stack that represents one worker machine. You must create a stack for each worker machine.

注意

Prerequisites

Configure an AWS account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in AWS.
Create and configure DNS, load balancers, and listeners in AWS.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.

Procedure

Create a JSON file that contains the parameter values that the CloudFormation template requires:

重要
If m4 instance types are not available in your region, such as with eu-west-3, use m5 types instead.
Copy the template from the CloudFormation template for worker machines section of this topic and save it as a YAML file on your computer. This template describes the networking objects and load balancers that your cluster requires.
If you specified an m5 instance type as the value for WorkerInstanceType, add that instance type to the WorkerInstanceType.AllowedValues parameter in the CloudFormation template.
Create a worker stack.
1. Launch the template:
  重要
  You must enter the command on a single line.

csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

In this example, two machines are joining the cluster. You might see more approved CSRs in the list.

If the CSRs were not approved, after all of the pending CSRs for the machines you added are in Pending status, approve the CSRs for your cluster machines:
注意
Because the CSRs rotate automatically, approve your CSRs within an hour of adding the machines to the cluster. If you do not approve them within an hour, the certificates will rotate, and more than two certificates will be present for each node. You must approve all of these certificates. Once the client CSR is approved, the Kubelet creates a secondary CSR for the serving certificate, which requires manual approval. Then, subsequent serving certificate renewal requests are automatically approved by the machine-approver if the Kubelet requests a new certificate with identical parameters.
- To approve them individually, run the following command for each valid CSR:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm certificate approve <csr_name>
```
```
$ oc adm certificate approve <csr_name> 
```
  1
  1
  <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```
```
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```

Now that your client requests are approved, you must review the server requests for each machine that you added to the cluster:

2.10.17.1. Image registry storage configuration

Additional instructions are provided for allowing the image registry to use block storage types by using the Recreate rollout strategy during upgrades.

2.10.17.1.1. Configuring registry storage for AWS with user-provisioned infrastructure

During installation, your cloud credentials are sufficient to create an Amazon S3 bucket and the Registry Operator will automatically configure storage.

If the Registry Operator cannot create an S3 bucket and automatically configure storage, you can create an S3 bucket and configure storage with the following procedure.

Prerequisites

A cluster on AWS with user-provisioned infrastructure.
For Amazon S3 storage, the secret is expected to contain two keys:
- REGISTRY_STORAGE_S3_ACCESSKEY
- REGISTRY_STORAGE_S3_SECRETKEY

Procedure

Use the following procedure if the Registry Operator cannot create an S3 bucket and automatically configure storage.

Set up a Bucket Lifecycle Policy to abort incomplete multipart uploads that are one day old.

Fill in the storage configuration in configs.imageregistry.operator.openshift.io/cluster:

Copy to Clipboard Toggle word wrap

oc edit configs.imageregistry.operator.openshift.io/cluster

$ oc edit configs.imageregistry.operator.openshift.io/cluster

Example configuration

Copy to Clipboard Toggle word wrap

storage:
  s3:
    bucket: <bucket-name>
    region: <region-name>

storage:
  s3:
    bucket: <bucket-name>
    region: <region-name>

警告

To secure your registry images in AWS, block public access to the S3 bucket.

2.10.17.1.2. Configuring storage for the image registry in non-production clusters

Procedure

To set the image registry storage to an empty directory:

Copy to Clipboard Toggle word wrap

oc patch configs.imageregistry.operator.openshift.io cluster --type merge --patch '{"spec":{"storage":{"emptyDir":{}}}}'

$ oc patch configs.imageregistry.operator.openshift.io cluster --type merge --patch '{"spec":{"storage":{"emptyDir":{}}}}'

警告

Configure this option for only non-production clusters.

If you run this command before the Image Registry Operator initializes its components, the oc patch command fails with the following error:

Copy to Clipboard Toggle word wrap

Error from server (NotFound): configs.imageregistry.operator.openshift.io "cluster" not found

Error from server (NotFound): configs.imageregistry.operator.openshift.io "cluster" not found

Wait a few minutes and run the command again.

Ensure that your registry is set to managed to enable building and pushing of images.
- Run:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc edit configs.imageregistry/cluster
```
```
$ oc edit configs.imageregistry/cluster
```
  Then, change the line
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow

```

2.10.18. Deleting the bootstrap resources

After you complete the initial Operator configuration for the cluster, remove the bootstrap resources from Amazon Web Services (AWS).

Prerequisites

You completed the initial Operator configuration for your cluster.

Procedure

Delete the bootstrap resources. If you used the CloudFormation template, delete its stack:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
aws cloudformation delete-stack --stack-name <name>
```
```
$ aws cloudformation delete-stack --stack-name <name> 
```

<name> is the name of your bootstrap stack.

2.10.19. Creating the Ingress DNS Records

Prerequisites

You deployed an OpenShift Container Platform cluster on Amazon Web Services (AWS) that uses infrastructure that you provisioned.
Install the OpenShift CLI (oc).
Install the jq package.
Download the AWS CLI and install it on your computer. See Install the AWS CLI Using the Bundled Installer (Linux, macOS, or Unix).

Procedure

Determine the routes to create.

To create a wildcard record, use *.apps.<cluster_name>.<domain_name>, where <cluster_name> is your cluster name, and <domain_name> is the Route 53 base domain for your OpenShift Container Platform cluster.

To create specific records, you must create a record for each route that your cluster uses, as shown in the output of the following command:

Copy to Clipboard Toggle word wrap

oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

$ oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

2.10.20. Completing an AWS installation on user-provisioned infrastructure

After you start the OpenShift Container Platform installation on Amazon Web Service (AWS) user-provisioned infrastructure, monitor the deployment to completion.

Prerequisites

Removed the bootstrap node for an OpenShift Container Platform cluster on user-provisioned AWS infrastructure.
Install the oc CLI and log in.

Procedure

Complete the cluster installation:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install --dir=<installation_directory> wait-for install-complete
```
```
$ ./openshift-install --dir=<installation_directory> wait-for install-complete 
```

For <installation_directory>, specify the path to the directory that you stored the installation files in.
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
INFO Waiting up to 30m0s for the cluster to initialize...
```
```
INFO Waiting up to 30m0s for the cluster to initialize...
```
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
Register your cluster on the Cluster registration page.

2.10.21. Next steps

Customize your cluster.
Configure image streams for the Cluster Samples Operator and the must-gather tool.
Learn how to use Operator Lifecycle Manager (OLM) on restricted networks.
If the mirror registry that you used to install your cluster has a trusted CA, add it to the cluster by configuring additional trust stores.
If necessary, you can opt out of remote health reporting.
If necessary, you can remove cloud provider credentials.

2.11. Uninstalling a cluster on AWS

You can remove a cluster that you deployed to Amazon Web Services (AWS).

2.11.1. Removing a cluster that uses installer-provisioned infrastructure

You can remove a cluster that uses installer-provisioned infrastructure from your cloud.

After uninstallation, check your cloud provider for any resources not removed properly, especially with User Provisioned Infrastructure (UPI) clusters. There might be resources that the installer did not create or that the installer is unable to access.

Prerequisites

Have a copy of the installation program that you used to deploy the cluster.
Have the files that the installation program generated when you created your cluster.

Procedure

From the computer that you used to install the cluster, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install destroy cluster \
--dir=<installation_directory> --log-level=info
```
```
$ ./openshift-install destroy cluster \
--dir=<installation_directory> --log-level=info 
```
1
```
 
```

1
For <installation_directory>, specify the path to the directory that you stored the installation files in.
2
To view different details, specify warn, debug, or error instead of info.
注意
You must specify the directory that contains the cluster definition files for your cluster. The installation program requires the metadata.json file in this directory to delete the cluster.
Optional: Delete the <installation_directory> directory and the OpenShift Container Platform installation program.

第 3 章 Installing on Azure

3.1. Configuring an Azure account

Before you can install OpenShift Container Platform, you must configure a Microsoft Azure account.

重要

All Azure resources that are available through public endpoints are subject to resource name restrictions, and you cannot create resources that use certain terms. For a list of terms that Azure restricts, see Resolve reserved resource name errors in the Azure documentation.

3.1.1. Azure account limits

The OpenShift Container Platform cluster uses a number of Microsoft Azure components, and the default Azure subscription and service limits, quotas, and constraints affect your ability to install OpenShift Container Platform clusters.

重要

Default limits vary by offer category types, such as Free Trial and Pay-As-You-Go, and by series, such as Dv2, F, and G. For example, the default for Enterprise Agreement subscriptions is 350 cores.

Check the limits for your subscription type and if necessary, increase quota limits for your account before you install a default cluster on Azure.

The following table summarizes the Azure components whose limits can impact your ability to install and run OpenShift Container Platform clusters.

Component Number of components required by default Default Azure limit Description

vCPU

20 per region

A default cluster requires 40 vCPUs, so you must increase the account limit.

By default, each cluster creates the following instances:

One bootstrap machine, which is removed after installation
Three control plane machines
Three compute machines

Because the bootstrap machine uses Standard_D4s_v3 machines, which use 4 vCPUs, the control plane machines use Standard_D8s_v3 virtual machines, which use 8 vCPUs, and the worker machines use Standard_D4s_v3 virtual machines, which use 4 vCPUs, a default cluster requires 40 vCPUs. The bootstrap node VM, which uses 4 vCPUs, is used only during installation.

To deploy more worker nodes, enable autoscaling, deploy large workloads, or use a different instance type, you must further increase the vCPU limit for your account to ensure that your cluster can deploy the machines that you require.

By default, the installation program distributes control plane and compute machines across all availability zones within a region. To ensure high availability for your cluster, select a region with at least three availability zones. If your region contains fewer than three availability zones, the installation program places more than one control plane machine in the available zones.

VNet

1000 per region

Each default cluster requires one Virtual Network (VNet), which contains two subnets.

Network interfaces

65,536 per region

Each default cluster requires six network interfaces. If you create more machines or your deployed workloads create load balancers, your cluster uses more network interfaces.

Network security groups

5000

Each default cluster Each cluster creates network security groups for each subnet in the VNet. The default cluster creates network security groups for the control plane and for the compute node subnets:

`controlplane`	Allows the control plane machines to be reached on port 6443 from anywhere
`node`	Allows worker nodes to be reached from the Internet on ports 80 and 443

Network load balancers

1000 per region

Each cluster creates the following load balancers:

`default`	Public IP address that load balances requests to ports 80 and 443 across worker machines
`internal`	Private IP address that load balances requests to ports 6443 and 22623 across control plane machines
`external`	Public IP address that load balances requests to port 6443 across control plane machines

If your applications create more Kubernetes LoadBalancer service objects, your cluster uses more load balancers.

Public IP addresses

Each of the two public load balancers uses a public IP address. The bootstrap machine also uses a public IP address so that you can SSH into the machine to troubleshoot issues during installation. The IP address for the bootstrap node is used only during installation.

Private IP addresses

The internal load balancer, each of the three control plane machines, and each of the three worker machines each use a private IP address.

3.1.2. Configuring a public DNS zone in Azure

To install OpenShift Container Platform, the Microsoft Azure account you use must have a dedicated public hosted DNS zone in your account. This zone must be authoritative for the domain. This service provides cluster DNS resolution and name lookup for external connections to the cluster.

Procedure

Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through Azure or another source.
注意
For more information about purchasing domains through Azure, see Buy a custom domain name for Azure App Service in the Azure documentation.
If you are using an existing domain and registrar, migrate its DNS to Azure. See Migrate an active DNS name to Azure App Service in the Azure documentation.
Configure DNS for your domain. Follow the steps in the Tutorial: Host your domain in Azure DNS in the Azure documentation to create a public hosted zone for your domain or subdomain, extract the new authoritative name servers, and update the registrar records for the name servers that your domain uses.
Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.
If you use a subdomain, follow your company’s procedures to add its delegation records to the parent domain.

3.1.3. Increasing Azure account limits

To increase an account limit, file a support request on the Azure portal.

注意

You can increase only one type of quota per support request.

Procedure

From the Azure portal, click Help + support in the lower left corner.
Click New support request and then select the required values:
1. From the Issue type list, select Service and subscription limits (quotas).
2. From the Subscription list, select the subscription to modify.
3. From the Quota type list, select the quota to increase. For example, select Compute-VM (cores-vCPUs) subscription limit increases to increase the number of vCPUs, which is required to install a cluster.
4. Click Next: Solutions.
On the Problem Details page, provide the required information for your quota increase:
1. Click Provide details and provide the required details in the Quota details window.
2. In the SUPPORT METHOD and CONTACT INFO sections, provide the issue severity and your contact details.
Click Next: Review + create and then click Create.

3.1.4. Required Azure roles

Your Microsoft Azure account must have the following roles for the subscription that you use:

User Access Administrator

To set roles on the Azure portal, see the Manage access to Azure resources using RBAC and the Azure portal in the Azure documentation.

3.1.5. Creating a service principal

Because OpenShift Container Platform and its installation program must create Microsoft Azure resources through Azure Resource Manager, you must create a service principal to represent it.

Prerequisites

Install or update the Azure CLI.
Install the jq package.
Your Azure account has the required roles for the subscription that you use.

Procedure

Log in to the Azure CLI:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
az login
```
```
$ az login
```
Log in to Azure in the web console by using your credentials.

If your Azure account uses subscriptions, ensure that you are using the right subscription.

View the list of available accounts and record the tenantId value for the subscription you want to use for your cluster:

Record the values of the appId and password parameters from the previous output. You need these values during OpenShift Container Platform installation.
Grant additional permissions to the service principal. The service principal requires the legacy Azure Active Directory Graph → Application.ReadWrite.OwnedBy permission and the User Access Administrator role for the cluster to assign credentials for its components.
1. To assign the User Access Administrator role, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```

3.1.7. Next steps

Install an OpenShift Container Platform cluster on Azure. You can install a customized cluster or quickly install a cluster with default options.

3.2. Manually creating IAM for Azure

3.2.1. Manually create IAM

Procedure

Run the OpenShift Container Platform installer to generate manifests:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
openshift-install create manifests --dir=mycluster
```
```
$ openshift-install create manifests --dir=mycluster
```

Insert a config map into the manifests directory so that the Cloud Credential Operator is placed in manual mode:

Copy to Clipboard Toggle word wrap

cat <<EOF > mycluster/manifests/cco-configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: cloud-credential-operator-config
  namespace: openshift-cloud-credential-operator

    release.openshift.io/create-only: "true"
data:
  disabled: "true"
EOF

$ cat <<EOF > mycluster/manifests/cco-configmap.yaml

  name: cloud-credential-operator-config
  namespace: openshift-cloud-credential-operator
  annotations:
    release.openshift.io/create-only: "true"
data:
  disabled: "true"
EOF

Remove the admin credential secret created using your local cloud credentials. This removal prevents your admin credential from being stored in the cluster:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm mycluster/openshift/99_cloud-creds-secret.yaml
```
```
$ rm mycluster/openshift/99_cloud-creds-secret.yaml

Obtain the OpenShift Container Platform release image your openshift-install binary is built to use:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
bin/openshift-install version
```
```
$ bin/openshift-install version
```
Example output

```
```
release image quay.io/openshift-release-dev/ocp-release:4.z.z-x86_64
```

Locate all CredentialsRequest objects in this release image that target the cloud you are deploying on:

Copy to Clipboard Toggle word wrap

oc adm release extract quay.io/openshift-release-dev/ocp-release:4.z.z-x86_64 --to ./release-image

$ oc adm release extract quay.io/openshift-release-dev/ocp-release:4.z.z-x86_64 --to ./release-image

Locate the CredentialsRequests in the extracted file:

Copy to Clipboard Toggle word wrap

grep -l "apiVersion: cloudcredential.openshift.io" * | xargs cat

$ grep -l "apiVersion: cloudcredential.openshift.io" * | xargs cat

注意

In a future OpenShift Container Platform release, there will be a new oc adm release command to scan for the CredentialsRequests and display them.

This displays the details for each request. Remember to ignore any CredentialsRequests where the spec.providerSpec.kind does not match the cloud provider you are installing to.

Sample CredentialsRequest object

Copy to Clipboard Toggle word wrap

apiVersion: cloudcredential.openshift.io/v1

    roleBindings:
    - role: Contributor

Create YAML files for secrets in the openshift-install manifests directory that you generated previously. The secrets must be stored using the namespace and secret name defined in each request.spec.secretRef. The format for the secret data varies for each cloud provider.
Proceed with cluster creation:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
openshift-install create cluster --dir=mycluster
```
```
$ openshift-install create cluster --dir=mycluster
```
重要
Before performing an upgrade, you might need to adjust your credentials if permissions have changed in the next release. In the future, the Cloud Credential Operator might prevent you from upgrading until you have indicated that you have addressed updated permissions.

3.2.2. Admin credentials root secret format

The format for the secret varies by cloud, and is also used for each CredentialsRequest secret.

Microsoft Azure secret format

Copy to Clipboard Toggle word wrap

apiVersion: v1
kind: Secret
metadata:
  namespace: kube-system
  name: azure-credentials
stringData:
  azure_subscription_id: <SubscriptionID>
  azure_client_id: <ClientID>
  azure_client_secret: <ClientSecret>
  azure_tenant_id: <TenantID>
  azure_resource_prefix: <ResourcePrefix>
  azure_resourcegroup: <ResourceGroup>
  azure_region: <Region>

apiVersion: v1
kind: Secret
metadata:
  namespace: kube-system
  name: azure-credentials
stringData:
  azure_subscription_id: <SubscriptionID>

  azure_client_secret: <ClientSecret>
  azure_tenant_id: <TenantID>
  azure_resource_prefix: <ResourcePrefix>
  azure_resourcegroup: <ResourceGroup>
  azure_region: <Region>

On Microsoft Azure, the credentials secret format includes two properties that must contain the cluster’s infrastructure ID, generated randomly for each cluster installation. This value can be found after running create manifests:

Copy to Clipboard Toggle word wrap

cat .openshift_install_state.json | jq '."*installconfig.ClusterID".InfraID' -r

$ cat .openshift_install_state.json | jq '."*installconfig.ClusterID".InfraID' -r

Example output

Copy to Clipboard Toggle word wrap

mycluster-2mpcn

mycluster-2mpcn

This value would be used in the secret data as follows:

Copy to Clipboard Toggle word wrap

azure_resource_prefix: mycluster-2mpcn
azure_resourcegroup: mycluster-2mpcn-rg

azure_resource_prefix: mycluster-2mpcn
azure_resourcegroup: mycluster-2mpcn-rg

3.2.2.1. Upgrades

3.2.3. Mint Mode

Mint Mode is supported for AWS, GCP, and Azure.

The benefits of Mint Mode include:

Each cluster component only has the permissions it requires.
Automatic, on-going reconciliation for cloud credentials including upgrades, which might require additional credentials or permissions.

One drawback is that Mint Mode requires admin credential storage in a cluster kube-system secret.

3.3. Installing a cluster quickly on Azure

In OpenShift Container Platform version 4.5, you can install a cluster on Microsoft Azure that uses the default configuration options.

3.3.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an Azure account to host the cluster and determine the tested and validated region to deploy the cluster to.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

3.3.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

3.3.3. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

3.3.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

3.3.5. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the directory name to store the files that the installation program creates.
2
To view different installation details, specify warn, debug, or error instead of info.
重要
Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
Provide values at the prompts:
1. Optional: Select an SSH key to use to access your cluster machines.
  注意
  For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
2. Select azure as the platform to target.
3. If you do not have a Microsoft Azure profile stored on your computer, specify the following Azure parameter values for your subscription and service principal:
  - azure subscription id: The subscription ID to use for the cluster. Specify the id value in your account output.
  - azure tenant id: The tenant ID. Specify the tenantId value in your account output.
  - azure service principal client id: The value of the appId parameter for the service principal.
  - azure service principal client secret: The value of the password parameter for the service principal.
4. Select the region to deploy the cluster to.
5. Select the base domain to deploy the cluster to. The base domain corresponds to the Azure DNS Zone that you created for your cluster.
6. Enter a descriptive name for your cluster.
  重要
  All Azure resources that are available through public endpoints are subject to resource name restrictions, and you cannot create resources that use certain terms. For a list of terms that Azure restricts, see Resolve reserved resource name errors in the Azure documentation.
7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.

3.3.8. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

3.4. Installing a cluster on Azure with customizations

In OpenShift Container Platform version 4.5, you can install a customized cluster on infrastructure that the installation program provisions on Microsoft Azure. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

3.4.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an Azure account to host the cluster and determine the tested and validated region to deploy the cluster to.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

3.4.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

3.4.3. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

3.4.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz

If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select azure as the platform to target.
  3. If you do not have a Microsoft Azure profile stored on your computer, specify the following Azure parameter values for your subscription and service principal:
    azure subscription id: The subscription ID to use for the cluster. Specify the id value in your account output.
    azure tenant id: The tenant ID. Specify the tenantId value in your account output.
    azure service principal client id: The value of the appId parameter for the service principal.
    azure service principal client secret: The value of the password parameter for the service principal.
  4. Select the region to deploy the cluster to.
  5. Select the base domain to deploy the cluster to. The base domain corresponds to the Azure DNS Zone that you created for your cluster.
  6. Enter a descriptive name for your cluster.
    重要
    All Azure resources that are available through public endpoints are subject to resource name restrictions, and you cannot create resources that use certain terms. For a list of terms that Azure restricts, see Resolve reserved resource name errors in the Azure documentation.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.
重要
If you disable simultaneous multithreading, ensure that your capacity planning accounts for the dramatically decreased machine performance. Use larger virtual machine types, such as Standard_D8s_v3, for your machines if you disable simultaneous multithreading.
5 8: You can specify the size of the disk to use in GB. Minimum recommendation for master nodes is 1024 GB.
9: Specify a list of zones to deploy your machines to. For high availability, specify at least two zones.
12: Specify the name of the resource group that contains the DNS zone for your base domain.
14 16: Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
15: You can optionally provide the sshKey value that you use to access the machines in your cluster.
注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.

3.4.6. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.

3.4.7. Installing the CLI by downloading the binary

You can install the OpenShift CLI (oc) in order to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS.

```

3.4.9. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

3.5. Installing a cluster on Azure with network customizations

In OpenShift Container Platform version 4.5, you can install a cluster with a customized network configuration on infrastructure that the installation program provisions on Microsoft Azure. By customizing your network configuration, your cluster can coexist with existing IP address allocations in your environment and integrate with existing MTU and VXLAN configurations.

You must set most of the network configuration parameters during installation, and you can modify only kubeProxy configuration parameters in a running cluster.

3.5.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an Azure account to host the cluster and determine the tested and validated region to deploy the cluster to.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

3.5.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

3.5.3. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

3.5.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

3.5.5. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Microsoft Azure.

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select azure as the platform to target.
  3. If you do not have a Microsoft Azure profile stored on your computer, specify the following Azure parameter values for your subscription and service principal:
    azure subscription id: The subscription ID to use for the cluster. Specify the id value in your account output.
    azure tenant id: The tenant ID. Specify the tenantId value in your account output.
    azure service principal client id: The value of the appId parameter for the service principal.
    azure service principal client secret: The value of the password parameter for the service principal.
  4. Select the region to deploy the cluster to.
  5. Select the base domain to deploy the cluster to. The base domain corresponds to the Azure DNS Zone that you created for your cluster.
  6. Enter a descriptive name for your cluster.
    重要
    All Azure resources that are available through public endpoints are subject to resource name restrictions, and you cannot create resources that use certain terms. For a list of terms that Azure restricts, see Resolve reserved resource name errors in the Azure documentation.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

1 10 12 14: Required. The installation program prompts you for this value.
2 6 11: If you do not provide these parameters and values, the installation program provides the default value.
3 7: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.
重要
If you disable simultaneous multithreading, ensure that your capacity planning accounts for the dramatically decreased machine performance. Use larger virtual machine types, such as Standard_D8s_v3, for your machines if you disable simultaneous multithreading.
5 8: You can specify the size of the disk to use in GB. Minimum recommendation for master nodes is 1024 GB.
9: Specify a list of zones to deploy your machines to. For high availability, specify at least two zones.
13: Specify the name of the resource group that contains the DNS zone for your base domain.
15 17: Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
16: You can optionally provide the sshKey value that you use to access the machines in your cluster.
注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.

3.5.6. Modifying advanced network configuration parameters

重要

Modifying the OpenShift Container Platform manifest files created by the installation program is not supported. Applying a manifest file that you create, as in the following procedure, is supported.

Prerequisites

Create the install-config.yaml file and complete any modifications to it.

Procedure

Use the following command to create manifests:

3.5.8. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.

3.5.9. Installing the CLI by downloading the binary

You can install the OpenShift CLI (oc) in order to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS.

3.5.11. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

3.6. Installing a cluster on Azure into an existing VNet

In OpenShift Container Platform version 4.5, you can install a cluster into an existing Azure Virtual Network (VNet) on Microsoft Azure. The installation program provisions the rest of the required infrastructure, which you can further customize. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

3.6.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an Azure account to host the cluster and determine the tested and validated region to deploy the cluster to.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

3.6.2. About reusing a VNet for your OpenShift Container Platform cluster

In OpenShift Container Platform 4.5, you can deploy a cluster into an existing Azure Virtual Network (VNet) in Microsoft Azure. If you do, you must also use existing subnets within the VNet and routing rules.

By deploying OpenShift Container Platform into an existing Azure VNet, you might be able to avoid service limit constraints in new accounts or more easily abide by the operational constraints that your company’s guidelines set. This is a good option to use if you cannot obtain the infrastructure creation permissions that are required to create the VNet.

重要

The use of an existing VNet requires the use of the updated Azure Private DNS (preview) feature. See Announcing Preview Refresh for Azure DNS Private Zones for more information about the limitations of this feature.

3.6.2.1. Requirements for using your VNet

When you deploy a cluster by using an existing VNet, you must perform additional network configuration before you install the cluster. In installer-provisioned infrastructure clusters, the installer usually creates the following components, but it does not create them when you install into an existing VNet:

Subnets
Route tables
VNets
Network Security Groups

If you use a custom VNet, you must correctly configure it and its subnets for the installation program and the cluster to use. The installation program cannot subdivide network ranges for the cluster to use, set route tables for the subnets, or set VNet options like DHCP, so you must do so before you install the cluster.

The cluster must be able to access the resource group that contains the existing VNet and subnets. While all of the resources that the cluster creates are placed in a separate resource group that it creates, some network resources are used from a separate group. Some cluster Operators must be able to access resources in both resource groups. For example, the Machine API controller attaches NICS for the virtual machines that it creates to subnets from the networking resource group.

Your VNet must meet the following characteristics:

The VNet’s CIDR block must contain the Networking.MachineCIDR range, which is the IP address pool for cluster machines.
The VNet and its subnets must belong to the same resource group, and the subnets must be configured to use Azure-assigned DHCP IP addresses instead of static IP addresses.

You must provide two subnets within your VNet, one for the control plane machines and one for the compute machines. Because Azure distributes machines in different availability zones within the region that you specify, your cluster will have high availability by default.

To ensure that the subnets that you provide are suitable, the installation program confirms the following data:

All the subnets that you specify exist.
You provide two private subnets, one for the control plane machines and one for the compute machines.
The subnet CIDRs belong to the machine CIDR that you specified. Machines are not provisioned in availability zones that you do not provide private subnets for. If required, the installation program creates public load balancers that manage the control plane and worker nodes, and Azure allocates a public IP address to them.

If you destroy a cluster that uses an existing VNet, the VNet is not deleted.

3.6.2.1.1. Network security group requirements

The network security groups for the subnets that host the compute and control plane machines require specific access to ensure that the cluster communication is correct. You must create rules to allow access to the required cluster communication ports.

重要

The network security group rules must be in place before you install the cluster. If you attempt to install a cluster without the required access, the installation program cannot reach the Azure APIs, and installation fails.

表 3.10. Required ports
Port	Description	Control plane	Compute
`80`	Allows HTTP traffic		x
`443`	Allows HTTPS traffic		x
`6443`	Allows communication to the control plane machines	x
`22623`	Allows communication to the machine config server	x

注意

Since cluster components do not modify the user-provided network security groups, which the Kubernetes controllers update, a pseudo-network security group is created for the Kubernetes controller to modify without impacting the rest of the environment.

3.6.2.2. Division of permissions

Starting with OpenShift Container Platform 4.3, you do not need all of the permissions that are required for an installation program-provisioned infrastructure cluster to deploy a cluster. This change mimics the division of permissions that you might have at your company: some individuals can create different resources in your clouds than others. For example, you might be able to create application-specific items, like instances, storage, and load balancers, but not networking-related components such as VNets, subnet, or ingress rules.

The Azure credentials that you use when you create your cluster do not need the networking permissions that are required to make VNets and core networking components within the VNet, such as subnets, routing tables, internet gateways, NAT, and VPN. You still need permission to make the application resources that the machines within the cluster require, such as load balancers, security groups, storage accounts, and nodes.

3.6.2.3. Isolation between clusters

Because the cluster is unable to modify network security groups in an existing subnet, there is no way to isolate clusters from each other on the VNet.

3.6.3. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

3.6.4. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```
1
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

3.6.5. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

3.6.6. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Microsoft Azure.

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select azure as the platform to target.
  3. If you do not have a Microsoft Azure profile stored on your computer, specify the following Azure parameter values for your subscription and service principal:
    azure subscription id: The subscription ID to use for the cluster. Specify the id value in your account output.
    azure tenant id: The tenant ID. Specify the tenantId value in your account output.
    azure service principal client id: The value of the appId parameter for the service principal.
    azure service principal client secret: The value of the password parameter for the service principal.
  4. Select the region to deploy the cluster to.
  5. Select the base domain to deploy the cluster to. The base domain corresponds to the Azure DNS Zone that you created for your cluster.
  6. Enter a descriptive name for your cluster.
    重要
    All Azure resources that are available through public endpoints are subject to resource name restrictions, and you cannot create resources that use certain terms. For a list of terms that Azure restricts, see Resolve reserved resource name errors in the Azure documentation.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

3.6.6.1. Installation configuration parameters

注意

After installation, you cannot modify these parameters in the install-config.yaml file.

重要

3.6.6.1.1. Required configuration parameters

Required installation configuration parameters are described in the following table:

1 10 11 17: Required. The installation program prompts you for this value.
2 6: If you do not provide these parameters and values, the installation program provides the default value.
3 7: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.

19: You can optionally provide the sshKey value that you use to access the machines in your cluster.
注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.

3.6.6.3. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```

```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

3.6.7. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.

3.6.10. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

3.7. Installing a private cluster on Azure

In OpenShift Container Platform version 4.5, you can install a private cluster into an existing Azure Virtual Network (VNet) on Microsoft Azure. The installation program provisions the rest of the required infrastructure, which you can further customize. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

3.7.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure an Azure account to host the cluster and determine the tested and validated region to deploy the cluster to.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

3.7.2. Private clusters

To deploy a private cluster, you must use existing networking that meets your requirements. Your cluster resources might be shared between other clusters on the network.

3.7.2.1. Private clusters in Azure

To create a private cluster on Microsoft Azure, you must provide an existing private VNet and subnets to host the cluster. The installation program must also be able to resolve the DNS records that the cluster requires. The installation program configures the Ingress Operator and API server for only internal traffic.

Depending how your network connects to the private VNET, you might need to use a DNS forwarder in order to resolve the cluster’s private DNS records. The cluster’s machines use 168.63.129.16 internally for DNS resolution. For more information, see What is Azure Private DNS? and What is IP address 168.63.129.16? in the Azure documentation.

The cluster still requires access to Internet to access the Azure APIs.

The following items are not required or created when you install a private cluster:

A BaseDomainResourceGroup, since the cluster does not create public records
Public IP addresses
Public DNS records

Public endpoints

Copy to Clipboard Toggle word wrap

The cluster is configured so that the Operators do not create public records for the cluster and all cluster machines are placed in the private subnets that you specify.

The cluster is configured so that the Operators do not create public records for the cluster and all cluster machines are placed in the private subnets that you specify.

3.7.2.1.1. Limitations

Private clusters on Azure are subject to only the limitations that are associated with the use of an existing VNet.

3.7.3. About reusing a VNet for your OpenShift Container Platform cluster

重要

3.7.3.1. Requirements for using your VNet

Subnets
Route tables
VNets
Network Security Groups

Your VNet must meet the following characteristics:

The VNet’s CIDR block must contain the Networking.MachineCIDR range, which is the IP address pool for cluster machines.
The VNet and its subnets must belong to the same resource group, and the subnets must be configured to use Azure-assigned DHCP IP addresses instead of static IP addresses.

To ensure that the subnets that you provide are suitable, the installation program confirms the following data:

All the subnets that you specify exist.
You provide two private subnets, one for the control plane machines and one for the compute machines.
The subnet CIDRs belong to the machine CIDR that you specified. Machines are not provisioned in availability zones that you do not provide private subnets for. If required, the installation program creates public load balancers that manage the control plane and worker nodes, and Azure allocates a public IP address to them.

If you destroy a cluster that uses an existing VNet, the VNet is not deleted.

3.7.3.1.1. Network security group requirements

重要

表 3.15. Required ports
Port	Description	Control plane	Compute
`80`	Allows HTTP traffic		x
`443`	Allows HTTPS traffic		x
`6443`	Allows communication to the control plane machines	x
`22623`	Allows communication to the machine config server	x

注意

3.7.3.2. Division of permissions

Starting with OpenShift Container Platform 4.3, you do not need all of the permissions that are required for an installation program-provisioned infrastructure cluster to deploy a cluster. This change mimics the division of permissions that you might have at your company: some individuals can create different resources in your clouds than others. For example, you might be able to create application-specific items, like instances, storage, and load balancers, but not networking-related components such as VNets, subnet, or ingress rules.

3.7.3.3. Isolation between clusters

Because the cluster is unable to modify network security groups in an existing subnet, there is no way to isolate clusters from each other on the VNet.

3.7.4. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

3.7.5. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

3.7.6. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

3.7.7. Manually creating the installation configuration file

Prerequisites

Obtain the OpenShift Container Platform installation program and the access token for your cluster.

Procedure

Create an installation directory to store your required installation assets in:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
mkdir <installation_directory>
```
```
$ mkdir <installation_directory>
```
重要
You must create a directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
Customize the following install-config.yaml file template and save it in the <installation_directory>.
注意
You must name this configuration file install-config.yaml.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the next step of the installation process. You must back it up now.

3.7.7.1. Installation configuration parameters

注意

After installation, you cannot modify these parameters in the install-config.yaml file.

重要

3.7.7.1.1. Required configuration parameters

20: How to publish the user-facing endpoints of your cluster. Set publish to Internal to deploy a private cluster, which cannot be accessed from the Internet. The default value is External.

3.7.7.3. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```

```
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
```
2
```
  noProxy: example.com 
```
3
```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

3.7.8. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.

Review details about the OpenShift Container Platform installation and update processes.
Configure an Azure account to host the cluster.
Download the Azure CLI and install it on your computer. See Install the Azure CLI in the Azure documentation. The documentation below was last tested using version 2.2.0 of the Azure CLI. Azure CLI commands might perform differently based on the version you use.
If you use a firewall and plan to use telemetry, you must configure the firewall to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.
注意
Be sure to also review this site list if you are configuring a proxy.

3.8.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

3.8.3. Configuring your Azure project

Before you can install OpenShift Container Platform, you must configure an Azure project to host it.

重要

3.8.3.1. Azure account limits

重要

Default limits vary by offer category types, such as Free Trial and Pay-As-You-Go, and by series, such as Dv2, F, and G. For example, the default for Enterprise Agreement subscriptions is 350 cores.

Check the limits for your subscription type and if necessary, increase quota limits for your account before you install a default cluster on Azure.

The following table summarizes the Azure components whose limits can impact your ability to install and run OpenShift Container Platform clusters.

Component Number of components required by default Default Azure limit Description

vCPU

20 per region

A default cluster requires 40 vCPUs, so you must increase the account limit.

By default, each cluster creates the following instances:

One bootstrap machine, which is removed after installation
Three control plane machines
Three compute machines

VNet

1000 per region

Each default cluster requires one Virtual Network (VNet), which contains two subnets.

Network interfaces

65,536 per region

Each default cluster requires six network interfaces. If you create more machines or your deployed workloads create load balancers, your cluster uses more network interfaces.

Network security groups

5000

`controlplane`	Allows the control plane machines to be reached on port 6443 from anywhere
`node`	Allows worker nodes to be reached from the Internet on ports 80 and 443

Network load balancers

1000 per region

Each cluster creates the following load balancers:

`default`	Public IP address that load balances requests to ports 80 and 443 across worker machines
`internal`	Private IP address that load balances requests to ports 6443 and 22623 across control plane machines
`external`	Public IP address that load balances requests to port 6443 across control plane machines

If your applications create more Kubernetes LoadBalancer service objects, your cluster uses more load balancers.

Public IP addresses

Private IP addresses

The internal load balancer, each of the three control plane machines, and each of the three worker machines each use a private IP address.

3.8.3.2. Configuring a public DNS zone in Azure

Procedure

Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through Azure or another source.
注意
For more information about purchasing domains through Azure, see Buy a custom domain name for Azure App Service in the Azure documentation.
If you are using an existing domain and registrar, migrate its DNS to Azure. See Migrate an active DNS name to Azure App Service in the Azure documentation.
Configure DNS for your domain. Follow the steps in the Tutorial: Host your domain in Azure DNS in the Azure documentation to create a public hosted zone for your domain or subdomain, extract the new authoritative name servers, and update the registrar records for the name servers that your domain uses.
Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.
If you use a subdomain, follow your company’s procedures to add its delegation records to the parent domain.

You can view Azure’s DNS solution by visiting this example for creating DNS zones.

3.8.3.3. Increasing Azure account limits

To increase an account limit, file a support request on the Azure portal.

注意

You can increase only one type of quota per support request.

Procedure

From the Azure portal, click Help + support in the lower left corner.
Click New support request and then select the required values:
1. From the Issue type list, select Service and subscription limits (quotas).
2. From the Subscription list, select the subscription to modify.
3. From the Quota type list, select the quota to increase. For example, select Compute-VM (cores-vCPUs) subscription limit increases to increase the number of vCPUs, which is required to install a cluster.
4. Click Next: Solutions.
On the Problem Details page, provide the required information for your quota increase:
1. Click Provide details and provide the required details in the Quota details window.
2. In the SUPPORT METHOD and CONTACT INFO sections, provide the issue severity and your contact details.
Click Next: Review + create and then click Create.

3.8.3.4. Certificate signing requests management

3.8.3.5. Required Azure roles

Your Microsoft Azure account must have the following roles for the subscription that you use:

User Access Administrator

To set roles on the Azure portal, see the Manage access to Azure resources using RBAC and the Azure portal in the Azure documentation.

3.8.3.6. Creating a service principal

Because OpenShift Container Platform and its installation program must create Microsoft Azure resources through Azure Resource Manager, you must create a service principal to represent it.

Prerequisites

Install or update the Azure CLI.
Install the jq package.
Your Azure account has the required roles for the subscription that you use.

Procedure

Log in to the Azure CLI:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```

}

Record the values of the appId and password parameters from the previous output. You need these values during OpenShift Container Platform installation.
Grant additional permissions to the service principal. The service principal requires the legacy Azure Active Directory Graph → Application.ReadWrite.OwnedBy permission and the User Access Administrator role for the cluster to assign credentials for its components.
1. To assign the User Access Administrator role, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow

3.8.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

3.8.5. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
Agent pid 31874
```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```

```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
```
Identity added: /home/<you>/<path>/<file_name> (<computer_name>)
```
1
Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program. If you install a cluster on infrastructure that you provision, you must provide this key to your cluster’s machines.

3.8.6. Creating the installation files for Azure

To install OpenShift Container Platform on Microsoft Azure using user-provisioned infrastructure, you must generate the files that the installation program needs to deploy your cluster and modify them so that the cluster creates only the machines that it will use. You generate and customize the install-config.yaml file, Kubernetes manifests, and Ignition config files.

3.8.6.1. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Microsoft Azure.

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select azure as the platform to target.
  3. If you do not have a Microsoft Azure profile stored on your computer, specify the following Azure parameter values for your subscription and service principal:
    azure subscription id: The subscription ID to use for the cluster. Specify the id value in your account output.
    azure tenant id: The tenant ID. Specify the tenantId value in your account output.
    azure service principal client id: The value of the appId parameter for the service principal.
    azure service principal client secret: The value of the password parameter for the service principal.
  4. Select the region to deploy the cluster to.
  5. Select the base domain to deploy the cluster to. The base domain corresponds to the Azure DNS Zone that you created for your cluster.
  6. Enter a descriptive name for your cluster.
    重要
    All Azure resources that are available through public endpoints are subject to resource name restrictions, and you cannot create resources that use certain terms. For a list of terms that Azure restricts, see Resolve reserved resource name errors in the Azure documentation.
  7. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

3.8.6.2. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```
1
```
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
```
2
```
  noProxy: example.com 
```
3
```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

3.8.6.3. Exporting common variables for ARM templates

You must export a common set of variables that are used with the provided Azure Resource Manager (ARM) templates used to assist in completing a user-provided infrastructure install on Microsoft Azure.

注意

Specific ARM templates can also require additional exported variables, which are detailed in their related procedures.

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Export common variables found in the install-config.yaml to be used by the provided ARM templates:

1
The value of the .metadata.name attribute from the install-config.yaml file.
2
The region to deploy the cluster into, for example centralus. This is the value of the .platform.azure.region attribute from the install-config.yaml file.
3
The SSH RSA public key file as a string. You must enclose the SSH key in quotes since it contains spaces. This is the value of the .sshKey attribute from the install-config.yaml file.
4
The base domain to deploy the cluster to. The base domain corresponds to the public DNS zone that you created for your cluster. This is the value of the .baseDomain attribute from the install-config.yaml file.
5
The resource group where the public DNS zone exists. This is the value of the .platform.azure.baseDomainResourceGroupName attribute from the install-config.yaml file.
For example:

3.8.6.4. Creating the Kubernetes manifest and Ignition config files

重要

Prerequisites

Obtain the OpenShift Container Platform installation program.
Create the install-config.yaml installation configuration file.

Procedure

Generate the Kubernetes manifests for the cluster:

Copy to Clipboard Toggle word wrap

./openshift-install create manifests --dir=<installation_directory>

$ ./openshift-install create manifests --dir=<installation_directory>

Example output

Copy to Clipboard Toggle word wrap

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

1: For <installation_directory>, specify the installation directory that contains the install-config.yaml file you created.

Because you create your own compute machines later in the installation process, you can safely ignore this warning.

Remove the Kubernetes manifest files that define the control plane machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
By removing these files, you prevent the cluster from automatically generating control plane machines.
Remove the Kubernetes manifest files that define the worker machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
Because you create and manage the worker machines yourself, you do not need to initialize these machines.
Modify the <installation_directory>/manifests/cluster-scheduler-02-config.yml Kubernetes manifest file to prevent pods from being scheduled on the control plane machines:
1. Open the <installation_directory>/manifests/cluster-scheduler-02-config.yml file.
2. Locate the mastersSchedulable parameter and set its value to False.
3. Save and exit the file.

If you do so, you must add ingress DNS records manually in a later step.

When configuring Azure on user-provisioned infrastructure, you must export some common variables defined in the manifest files to use later in the Azure Resource Manager (ARM) templates:
1. Export the infrastructure ID by using the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
export INFRA_ID=<infra_id>
```
```
$ export INFRA_ID=<infra_id> 
```
  1
  1
  The OpenShift Container Platform cluster has been assigned an identifier (INFRA_ID) in the form of <cluster_name>-<random_string>. This will be used as the base name for most resources created using the provided ARM templates. This is the value of the .status.infrastructureName attribute from the manifests/cluster-infrastructure-02-config.yml file.
2. Export the resource group by using the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
export RESOURCE_GROUP=<resource_group>
```
```
$ export RESOURCE_GROUP=<resource_group> 
```
  1
  1
  All resources created in this Azure deployment exists as part of a resource group. The resource group name is also based on the INFRA_ID, in the form of <cluster_name>-<random_string>-rg. This is the value of the .status.platformStatus.azure.resourceGroupName attribute from the manifests/cluster-infrastructure-02-config.yml file.

Obtain the Ignition config files:

Copy to Clipboard Toggle word wrap

./openshift-install create ignition-configs --dir=<installation_directory>

$ ./openshift-install create ignition-configs --dir=<installation_directory>

1: For <installation_directory>, specify the same installation directory.

3.8.7. Creating the Azure resource group and identity

You must create a Microsoft Azure resource group and an identity for that resource group. These are both used during the installation of your OpenShift Container Platform cluster on Azure.

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.

Procedure

Create the resource group in a supported Azure region:

Copy to Clipboard Toggle word wrap

az group create --name ${RESOURCE_GROUP} --location ${AZURE_REGION}

$ az group create --name ${RESOURCE_GROUP} --location ${AZURE_REGION}

Create an Azure identity for the resource group:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
az identity create -g ${RESOURCE_GROUP} -n ${INFRA_ID}-identity
```
```
$ az identity create -g ${RESOURCE_GROUP} -n ${INFRA_ID}-identity
```
This is used to grant the required access to Operators in your cluster. For example, this allows the Ingress Operator to create a public IP and its load balancer. You must assign the Azure identity to a role.

Grant the Contributor role to the Azure identity:

Export the following variables required by the Azure role assignment:

Copy to Clipboard Toggle word wrap

export PRINCIPAL_ID=`az identity show -g ${RESOURCE_GROUP} -n ${INFRA_ID}-identity --query principalId --out tsv`

$ export PRINCIPAL_ID=`az identity show -g ${RESOURCE_GROUP} -n ${INFRA_ID}-identity --query principalId --out tsv`

Copy to Clipboard Toggle word wrap

export RESOURCE_GROUP_ID=`az group show -g ${RESOURCE_GROUP} --query id --out tsv`

$ export RESOURCE_GROUP_ID=`az group show -g ${RESOURCE_GROUP} --query id --out tsv`

Assign the Contributor role to the identity:

Copy to Clipboard Toggle word wrap

az role assignment create --assignee "${PRINCIPAL_ID}" --role 'Contributor' --scope "${RESOURCE_GROUP_ID}"

$ az role assignment create --assignee "${PRINCIPAL_ID}" --role 'Contributor' --scope "${RESOURCE_GROUP_ID}"

3.8.8. Uploading the RHCOS cluster image and bootstrap Ignition config file

The Azure client does not support deployments based on files existing locally; therefore, you must copy and store the RHCOS virtual hard disk (VHD) cluster image and bootstrap Ignition config file in a storage container so they are accessible during deployment.

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.

Procedure

Create an Azure storage account to store the VHD cluster image:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
az storage account create -g ${RESOURCE_GROUP} --location ${AZURE_REGION} --name ${CLUSTER_NAME}sa --kind Storage --sku Standard_LRS
```
```
$ az storage account create -g ${RESOURCE_GROUP} --location ${AZURE_REGION} --name ${CLUSTER_NAME}sa --kind Storage --sku Standard_LRS
```
警告
The Azure storage account name must be between 3 and 24 characters in length and use numbers and lower-case letters only. If your CLUSTER_NAME variable does not follow these restrictions, you must manually define the Azure storage account name. For more information on Azure storage account name restrictions, see Resolve errors for storage account names in the Azure documentation.

Export the storage account key as an environment variable:

Copy to Clipboard Toggle word wrap

export ACCOUNT_KEY=`az storage account keys list -g ${RESOURCE_GROUP} --account-name ${CLUSTER_NAME}sa --query "[0].value" -o tsv`

$ export ACCOUNT_KEY=`az storage account keys list -g ${RESOURCE_GROUP} --account-name ${CLUSTER_NAME}sa --query "[0].value" -o tsv`

Choose the RHCOS version to use and export the URL of its VHD to an environment variable:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
export VHD_URL=`curl -s https://raw.githubusercontent.com/openshift/installer/release-4.5/data/data/rhcos.json | jq -r .azure.url`
```
```
$ export VHD_URL=`curl -s https://raw.githubusercontent.com/openshift/installer/release-4.5/data/data/rhcos.json | jq -r .azure.url`
```
重要
The RHCOS images might not change with every release of OpenShift Container Platform. You must specify an image with the highest version that is less than or equal to the OpenShift Container Platform version that you install. Use the image version that matches your OpenShift Container Platform version if it is available.

Copy the chosen VHD to a blob:

Copy to Clipboard Toggle word wrap

az storage container create --name vhd --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY}

$ az storage container create --name vhd --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY}

Copy to Clipboard Toggle word wrap

az storage blob copy start --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} --destination-blob "rhcos.vhd" --destination-container vhd --source-uri "${VHD_URL}"

$ az storage blob copy start --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} --destination-blob "rhcos.vhd" --destination-container vhd --source-uri "${VHD_URL}"

To track the progress of the VHD copy task, run this script:

Copy to Clipboard Toggle word wrap

status="unknown"
while [ "$status" != "success" ]
do
  status=`az storage blob show --container-name vhd --name "rhcos.vhd" --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -o tsv --query properties.copy.status`
  echo $status
done

status="unknown"
while [ "$status" != "success" ]
do
  status=`az storage blob show --container-name vhd --name "rhcos.vhd" --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -o tsv --query properties.copy.status`
  echo $status
done

Create a blob storage container and upload the generated bootstrap.ign file:

Copy to Clipboard Toggle word wrap

az storage container create --name files --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} --public-access blob

$ az storage container create --name files --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} --public-access blob

Copy to Clipboard Toggle word wrap

az storage blob upload --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -c "files" -f "<installation_directory>/bootstrap.ign" -n "bootstrap.ign"

$ az storage blob upload --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -c "files" -f "<installation_directory>/bootstrap.ign" -n "bootstrap.ign"

3.8.9. Example for creating DNS zones

DNS records are required for clusters that use user-provisioned infrastructure. You should choose the DNS strategy that fits your scenario.

For this example, Azure’s DNS solution is used, so you will create a new public DNS zone for external (internet) visibility and a private DNS zone for internal cluster resolution.

注意

The public DNS zone is not required to exist in the same resource group as the cluster deployment and might already exist in your organization for the desired base domain. If that is the case, you can skip creating the public DNS zone; be sure the installation config you generated earlier reflects that scenario.

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.

Procedure

Create the new public DNS zone in the resource group exported in the BASE_DOMAIN_RESOURCE_GROUP environment variable:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
az network dns zone create -g ${BASE_DOMAIN_RESOURCE_GROUP} -n ${CLUSTER_NAME}.${BASE_DOMAIN}
```
```
$ az network dns zone create -g ${BASE_DOMAIN_RESOURCE_GROUP} -n ${CLUSTER_NAME}.${BASE_DOMAIN}
```
You can skip this step if you are using a public DNS zone that already exists.

Create the private DNS zone in the same resource group as the rest of this deployment:

Copy to Clipboard Toggle word wrap

az network private-dns zone create -g ${RESOURCE_GROUP} -n ${CLUSTER_NAME}.${BASE_DOMAIN}

$ az network private-dns zone create -g ${RESOURCE_GROUP} -n ${CLUSTER_NAME}.${BASE_DOMAIN}

You can learn more about configuring a public DNS zone in Azure by visiting that section.

3.8.10. Creating a VNet in Azure

You must create a virtual network (VNet) in Microsoft Azure for your OpenShift Container Platform cluster to use. You can customize the VNet to meet your requirements. One way to create the VNet is to modify the provided Azure Resource Manager (ARM) template.

注意

If you do not use the provided ARM template to create your Azure infrastructure, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.

Procedure

Copy the template from the ARM template for the VNet section of this topic and save it as 01_vnet.json in your cluster’s installation directory. This template describes the VNet that your cluster requires.

Create the deployment by using the az CLI:

Copy to Clipboard Toggle word wrap

az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/01_vnet.json" \
  --parameters baseName="${INFRA_ID}"

$ az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/01_vnet.json" \
  --parameters baseName="${INFRA_ID}"

1: The base name to be used in resource names; this is usually the cluster’s infrastructure ID.

Link the VNet template to the private DNS zone:

Copy to Clipboard Toggle word wrap

az network private-dns link vnet create -g ${RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n ${INFRA_ID}-network-link -v "${INFRA_ID}-vnet" -e false

$ az network private-dns link vnet create -g ${RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n ${INFRA_ID}-network-link -v "${INFRA_ID}-vnet" -e false

3.8.10.1. ARM template for the VNet

You can use the following Azure Resource Manager (ARM) template to deploy the VNet that you need for your OpenShift Container Platform cluster:

3.8.11. Deploying the RHCOS cluster image for the Azure infrastructure

You must use a valid Red Hat Enterprise Linux CoreOS (RHCOS) image for Microsoft Azure for your OpenShift Container Platform nodes.

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.
Store the RHCOS virtual hard disk (VHD) cluster image in an Azure storage container.
Store the bootstrap Ignition config file in an Azure storage container.

Procedure

Copy the template from the ARM template for image storage section of this topic and save it as 02_storage.json in your cluster’s installation directory. This template describes the image storage that your cluster requires.

Export the RHCOS VHD blob URL as a variable:

Copy to Clipboard Toggle word wrap

export VHD_BLOB_URL=`az storage blob url --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -c vhd -n "rhcos.vhd" -o tsv`

$ export VHD_BLOB_URL=`az storage blob url --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -c vhd -n "rhcos.vhd" -o tsv`

Deploy the cluster image:

Copy to Clipboard Toggle word wrap

az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/02_storage.json" \
  --parameters vhdBlobURL="${VHD_BLOB_URL}" \

$ az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/02_storage.json" \
  --parameters vhdBlobURL="${VHD_BLOB_URL}" \


  --parameters baseName="${INFRA_ID}"

1: The blob URL of the RHCOS VHD to be used to create master and worker machines.
2: The base name to be used in resource names; this is usually the cluster’s infrastructure ID.

3.8.11.1. ARM template for image storage

3.8.12. Networking requirements for user-provisioned infrastructure

All the Red Hat Enterprise Linux CoreOS (RHCOS) machines require network in initramfs during boot to fetch Ignition config from the machine config server.

During the initial boot, the machines require either a DHCP server or that static IP addresses be set on each host in the cluster in order to establish a network connection, which allows them to download their Ignition config files.

It is recommended to use the DHCP server to manage the machines for the cluster long-term. Ensure that the DHCP server is configured to provide persistent IP addresses and host names to the cluster machines.

The Kubernetes API server, which runs on each master node after a successful cluster installation, must be able to resolve the node names of the cluster machines. If the API servers and worker nodes are in different zones, you can configure a default DNS search zone to allow the API server to resolve the node names. Another supported approach is to always refer to hosts by their fully-qualified domain names in both the node objects and all DNS requests.

You must configure the network connectivity between machines to allow cluster components to communicate. Each machine must be able to resolve the host names of all other machines in the cluster.

Network topology requirements

The infrastructure that you provision for your cluster must meet the following network topology requirements.

重要

OpenShift Container Platform requires all nodes to have internet access to pull images for platform containers and provide telemetry data to Red Hat.

Load balancers

Before you install OpenShift Container Platform, you must provision two load balancers that meet the following requirements:

API load balancer: Provides a common endpoint for users, both human and machine, to interact with and configure the platform. Configure the following conditions:

Layer 4 load balancing only. This can be referred to as Raw TCP, SSL Passthrough, or SSL Bridge mode. If you use SSL Bridge mode, you must enable Server Name Indication (SNI) for the API routes.
A stateless load balancing algorithm. The options vary based on the load balancer implementation.

注意

Session persistence is not required for the API load balancer to function properly.

Configure the following ports on both the front and back of the load balancers:

表 3.23. API load balancer
Port	Back-end machines (pool members)	Internal	External	Description
`6443`	Bootstrap and control plane. You remove the bootstrap machine from the load balancer after the bootstrap machine initializes the cluster control plane. You must configure the `/readyz` endpoint for the API server health check probe.	X	X	Kubernetes API server
`22623`	Bootstrap and control plane. You remove the bootstrap machine from the load balancer after the bootstrap machine initializes the cluster control plane.	X		Machine config server

注意

The load balancer must be configured to take a maximum of 30 seconds from the time the API server turns off the /readyz endpoint to the removal of the API server instance from the pool. Within the time frame after /readyz returns an error or becomes healthy, the endpoint must have been removed or added. Probing every 5 or 10 seconds, with two successful requests to become healthy and three to become unhealthy, are well-tested values.

Application Ingress load balancer: Provides an Ingress point for application traffic flowing in from outside the cluster. Configure the following conditions:

Layer 4 load balancing only. This can be referred to as Raw TCP, SSL Passthrough, or SSL Bridge mode. If you use SSL Bridge mode, you must enable Server Name Indication (SNI) for the Ingress routes.
A connection-based or session-based persistence is recommended, based on the options available and types of applications that will be hosted on the platform.

Configure the following ports on both the front and back of the load balancers:

表 3.24. Application Ingress load balancer
Port	Back-end machines (pool members)	Internal	External	Description
`443`	The machines that run the Ingress router pods, compute, or worker, by default.	X	X	HTTPS traffic
`80`	The machines that run the Ingress router pods, compute, or worker, by default.	X	X	HTTP traffic

提示

If the true IP address of the client can be seen by the load balancer, enabling source IP-based session persistence can improve performance for applications that use end-to-end TLS encryption.

注意

A working configuration for the Ingress router is required for an OpenShift Container Platform cluster. You must configure the Ingress router after the control plane initializes.

NTP configuration

OpenShift Container Platform clusters are configured to use a public Network Time Protocol (NTP) server by default. If you want to use a local enterprise NTP server, or if your cluster is being deployed in a disconnected network, you can configure the cluster to use a specific time server. For more information, see the documentation for Configuring chrony time service.

If a DHCP server provides NTP server information, the chrony time service on the Red Hat Enterprise Linux CoreOS (RHCOS) machines read the information and can sync the clock with the NTP servers.

3.8.13. Creating networking and load balancing components in Azure

You must configure networking and load balancing in Microsoft Azure for your OpenShift Container Platform cluster to use. One way to create these components is to modify the provided Azure Resource Manager (ARM) template.

注意

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.
Create and configure a VNet and associated subnets in Azure.

Procedure

Copy the template from the ARM template for the network and load balancers section of this topic and save it as 03_infra.json in your cluster’s installation directory. This template describes the networking and load balancing objects that your cluster requires.

Create the deployment by using the az CLI:

Copy to Clipboard Toggle word wrap

az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/03_infra.json" \
  --parameters privateDNSZoneName="${CLUSTER_NAME}.${BASE_DOMAIN}" \
  --parameters baseName="${INFRA_ID}"

$ az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/03_infra.json" \
  --parameters privateDNSZoneName="${CLUSTER_NAME}.${BASE_DOMAIN}" \


  --parameters baseName="${INFRA_ID}"

1: The name of the private DNS zone.
2: The base name to be used in resource names; this is usually the cluster’s infrastructure ID.

Create an api DNS record in the public zone for the API public load balancer. The ${BASE_DOMAIN_RESOURCE_GROUP} variable must point to the resource group where the public DNS zone exists.

Export the following variable:

Copy to Clipboard Toggle word wrap

export PUBLIC_IP=`az network public-ip list -g ${RESOURCE_GROUP} --query "[?name=='${INFRA_ID}-master-pip'] | [0].ipAddress" -o tsv`

$ export PUBLIC_IP=`az network public-ip list -g ${RESOURCE_GROUP} --query "[?name=='${INFRA_ID}-master-pip'] | [0].ipAddress" -o tsv`

Create the DNS record in a new public zone:

Copy to Clipboard Toggle word wrap

az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n api -a ${PUBLIC_IP} --ttl 60

$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n api -a ${PUBLIC_IP} --ttl 60

If you are adding the cluster to an existing public zone, you can create the DNS record in it instead:

Copy to Clipboard Toggle word wrap

az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${BASE_DOMAIN} -n api.${CLUSTER_NAME} -a ${PUBLIC_IP} --ttl 60

$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${BASE_DOMAIN} -n api.${CLUSTER_NAME} -a ${PUBLIC_IP} --ttl 60

3.8.13.1. ARM template for the network and load balancers

You can use the following Azure Resource Manager (ARM) template to deploy the networking objects and load balancers that you need for your OpenShift Container Platform cluster:

3.8.14. Creating the bootstrap machine in Azure

You must create the bootstrap machine in Microsoft Azure to use during OpenShift Container Platform cluster initialization. One way to create this machine is to modify the provided Azure Resource Manager (ARM) template.

注意

If you do not use the provided ARM template to create your bootstrap machine, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.
Create and configure a VNet and associated subnets in Azure.
Create and configure networking and load balancers in Azure.
Create control plane and compute roles.

Procedure

Copy the template from the ARM template for the bootstrap machine section of this topic and save it as 04_bootstrap.json in your cluster’s installation directory. This template describes the bootstrap machine that your cluster requires.

Export the following variables required by the bootstrap machine deployment:

Copy to Clipboard Toggle word wrap

export BOOTSTRAP_URL=`az storage blob url --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -c "files" -n "bootstrap.ign" -o tsv`
export BOOTSTRAP_IGNITION=`jq -rcnM --arg v "2.2.0" --arg url ${BOOTSTRAP_URL} '{ignition:{version:$v,config:{replace:{source:$url}}}}' | base64 -w0`

$ export BOOTSTRAP_URL=`az storage blob url --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -c "files" -n "bootstrap.ign" -o tsv`
$ export BOOTSTRAP_IGNITION=`jq -rcnM --arg v "2.2.0" --arg url ${BOOTSTRAP_URL} '{ignition:{version:$v,config:{replace:{source:$url}}}}' | base64 -w0`

Create the deployment by using the az CLI:

Copy to Clipboard Toggle word wrap

az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/04_bootstrap.json" \
  --parameters bootstrapIgnition="${BOOTSTRAP_IGNITION}" \
  --parameters sshKeyData="${SSH_KEY}" \
  --parameters baseName="${INFRA_ID}"

$ az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/04_bootstrap.json" \
  --parameters bootstrapIgnition="${BOOTSTRAP_IGNITION}" \


  --parameters sshKeyData="${SSH_KEY}" \


  --parameters baseName="${INFRA_ID}"

1: The bootstrap Ignition content for the bootstrap cluster.
2: The SSH RSA public key file as a string.
3: The base name to be used in resource names; this is usually the cluster’s infrastructure ID.

3.8.14.1. ARM template for the bootstrap machine

You can use the following Azure Resource Manager (ARM) template to deploy the bootstrap machine that you need for your OpenShift Container Platform cluster:

3.8.15. Creating the control plane machines in Azure

You must create the control plane machines in Microsoft Azure for your cluster to use. One way to create these machines is to modify the provided Azure Resource Manager (ARM) template.

注意

If you do not use the provided ARM template to create your control plane machines, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.
Create and configure a VNet and associated subnets in Azure.
Create and configure networking and load balancers in Azure.
Create control plane and compute roles.
Create the bootstrap machine.

Procedure

Copy the template from the ARM template for control plane machines section of this topic and save it as 05_masters.json in your cluster’s installation directory. This template describes the control plane machines that your cluster requires.

Export the following variable needed by the control plane machine deployment:

Copy to Clipboard Toggle word wrap

export MASTER_IGNITION=`cat <installation_directory>/master.ign | base64`

$ export MASTER_IGNITION=`cat <installation_directory>/master.ign | base64`

Create the deployment by using the az CLI:

Copy to Clipboard Toggle word wrap

az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/05_masters.json" \
  --parameters masterIgnition="${MASTER_IGNITION}" \
  --parameters sshKeyData="${SSH_KEY}" \
  --parameters privateDNSZoneName="${CLUSTER_NAME}.${BASE_DOMAIN}"

$ az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/05_masters.json" \
  --parameters masterIgnition="${MASTER_IGNITION}" \


  --parameters sshKeyData="${SSH_KEY}" \


  --parameters privateDNSZoneName="${CLUSTER_NAME}.${BASE_DOMAIN}"


  --parameters baseName="${INFRA_ID}"

1: The Ignition content for the master nodes.
2: The SSH RSA public key file as a string.
3: The name of the private DNS zone to which the master nodes are attached.
4: The base name to be used in resource names; this is usually the cluster’s infrastructure ID.

3.8.15.1. ARM template for control plane machines

You can use the following Azure Resource Manager (ARM) template to deploy the control plane machines that you need for your OpenShift Container Platform cluster:

3.8.16. Wait for bootstrap completion and remove bootstrap resources in Azure

After you create all of the required infrastructure in Microsoft Azure, wait for the bootstrap process to complete on the machines that you provisioned by using the Ignition config files that you generated with the installation program.

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.
Create and configure a VNet and associated subnets in Azure.
Create and configure networking and load balancers in Azure.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.

Procedure

Change to the directory that contains the installation program and run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install wait-for bootstrap-complete --dir=<installation_directory> \
    --log-level info
```
```
$ ./openshift-install wait-for bootstrap-complete --dir=<installation_directory> \ 
```
1
```
    --log-level info 
```

1
For <installation_directory>, specify the path to the directory that you stored the installation files in.
2
To view different installation details, specify warn, debug, or error instead of info.
If the command exits without a FATAL warning, your production control plane has initialized.

Delete the bootstrap resources:

3.8.17. Creating additional worker machines in Azure

You can create worker machines in Microsoft Azure for your cluster to use by launching individual instances discretely or by automated processes outside the cluster, such as auto scaling groups. You can also take advantage of the built-in cluster scaling mechanisms and the machine API in OpenShift Container Platform.

In this example, you manually launch one instance by using the Azure Resource Manager (ARM) template. Additional instances can be launched by including additional resources of type 06_workers.json in the file.

注意

If you do not use the provided ARM template to create your worker machines, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure an Azure account.
Generate the Ignition config files for your cluster.
Create and configure a VNet and associated subnets in Azure.
Create and configure networking and load balancers in Azure.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.

Procedure

Copy the template from the ARM template for worker machines section of this topic and save it as 06_workers.json in your cluster’s installation directory. This template describes the worker machines that your cluster requires.

Export the following variable needed by the worker machine deployment:

Copy to Clipboard Toggle word wrap

export WORKER_IGNITION=`cat <installation_directory>/worker.ign | base64`

$ export WORKER_IGNITION=`cat <installation_directory>/worker.ign | base64`

Create the deployment by using the az CLI:

Copy to Clipboard Toggle word wrap

az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/06_workers.json" \
  --parameters workerIgnition="${WORKER_IGNITION}" \
  --parameters sshKeyData="${SSH_KEY}" \
  --parameters baseName="${INFRA_ID}"

$ az deployment group create -g ${RESOURCE_GROUP} \
  --template-file "<installation_directory>/06_workers.json" \
  --parameters workerIgnition="${WORKER_IGNITION}" \


  --parameters sshKeyData="${SSH_KEY}" \


  --parameters baseName="${INFRA_ID}"

1: The Ignition content for the worker nodes.
2: The SSH RSA public key file as a string.
3: The base name to be used in resource names; this is usually the cluster’s infrastructure ID.

3.8.17.1. ARM template for worker machines

You can use the following Azure Resource Manager (ARM) template to deploy the worker machines that you need for your OpenShift Container Platform cluster:

Procedure

Confirm that the cluster recognizes the machines:

Copy to Clipboard Toggle word wrap

oc get nodes

$ oc get nodes

Example output

Copy to Clipboard Toggle word wrap

NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  63m  v1.18.3
master-1  Ready     master  63m  v1.18.3
master-2  Ready     master  64m  v1.18.3
worker-0  NotReady  worker  76s  v1.18.3
worker-1  NotReady  worker  70s  v1.18.3

NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  63m  v1.18.3
master-1  Ready     master  63m  v1.18.3
master-2  Ready     master  64m  v1.18.3
worker-0  NotReady  worker  76s  v1.18.3
worker-1  NotReady  worker  70s  v1.18.3

The output lists all of the machines that you created.

Review the pending CSRs and ensure that you see the client requests with the Pending or Approved status for each machine that you added to the cluster:

Copy to Clipboard Toggle word wrap

oc get csr

$ oc get csr

Example output

Copy to Clipboard Toggle word wrap

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-8b2br   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-8b2br   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

In this example, two machines are joining the cluster. You might see more approved CSRs in the list.

If the CSRs were not approved, after all of the pending CSRs for the machines you added are in Pending status, approve the CSRs for your cluster machines:
注意
Because the CSRs rotate automatically, approve your CSRs within an hour of adding the machines to the cluster. If you do not approve them within an hour, the certificates will rotate, and more than two certificates will be present for each node. You must approve all of these certificates. Once the client CSR is approved, the Kubelet creates a secondary CSR for the serving certificate, which requires manual approval. Then, subsequent serving certificate renewal requests are automatically approved by the machine-approver if the Kubelet requests a new certificate with identical parameters.
- To approve them individually, run the following command for each valid CSR:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm certificate approve <csr_name>
```
```
$ oc adm certificate approve <csr_name> 
```
  1
  1
  <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```
```
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```

Now that your client requests are approved, you must review the server requests for each machine that you added to the cluster:

Copy to Clipboard Toggle word wrap

oc get csr

$ oc get csr

Example output

Copy to Clipboard Toggle word wrap

NAME        AGE     REQUESTOR                                                                   CONDITION

...

If the remaining CSRs are not approved, and are in the Pending status, approve the CSRs for your cluster machines:
- To approve them individually, run the following command for each valid CSR:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm certificate approve <csr_name>
```
```
$ oc adm certificate approve <csr_name> 
```
  1
  1
  <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve
```
```
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve
```

After all client and server CSRs have been approved, the machines have the Ready status. Verify this by running the following command:

Copy to Clipboard Toggle word wrap

oc get nodes

$ oc get nodes

Example output

Copy to Clipboard Toggle word wrap

3.8.21. Adding the Ingress DNS records

If you removed the DNS Zone configuration when creating Kubernetes manifests and generating Ignition configs, you must manually create DNS records that point at the Ingress load balancer. You can create either a wildcard *.apps.{baseDomain}. or specific records. You can use A, CNAME, and other records per your requirements.

Prerequisites

You deployed an OpenShift Container Platform cluster on Microsoft Azure by using infrastructure that you provisioned.
Install the OpenShift CLI (oc).
Install the jq package.
Install or update the Azure CLI.

Procedure

Confirm the Ingress router has created a load balancer and populated the EXTERNAL-IP field:

Copy to Clipboard Toggle word wrap

oc -n openshift-ingress get service router-default

$ oc -n openshift-ingress get service router-default

Example output

Copy to Clipboard Toggle word wrap

NAME             TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)                      AGE
router-default   LoadBalancer   172.30.20.10   35.130.120.110   80:32288/TCP,443:31215/TCP   20

NAME             TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)                      AGE
router-default   LoadBalancer   172.30.20.10   35.130.120.110   80:32288/TCP,443:31215/TCP   20

Export the Ingress router IP as a variable:

Copy to Clipboard Toggle word wrap

export PUBLIC_IP_ROUTER=`oc -n openshift-ingress get service router-default --no-headers | awk '{print $4}'`

$ export PUBLIC_IP_ROUTER=`oc -n openshift-ingress get service router-default --no-headers | awk '{print $4}'`

Add a *.apps record to the public DNS zone.

If you are adding this cluster to a new public zone, run:

Copy to Clipboard Toggle word wrap

az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n *.apps -a ${PUBLIC_IP_ROUTER} --ttl 300

$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n *.apps -a ${PUBLIC_IP_ROUTER} --ttl 300

If you are adding this cluster to an already existing public zone, run:

Copy to Clipboard Toggle word wrap

az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${BASE_DOMAIN} -n *.apps.${CLUSTER_NAME} -a ${PUBLIC_IP_ROUTER} --ttl 300

$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${BASE_DOMAIN} -n *.apps.${CLUSTER_NAME} -a ${PUBLIC_IP_ROUTER} --ttl 300

Add a *.apps record to the private DNS zone:

Create a *.apps record by using the following command:

Copy to Clipboard Toggle word wrap

az network private-dns record-set a create -g ${RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n *.apps --ttl 300

$ az network private-dns record-set a create -g ${RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n *.apps --ttl 300

Add the *.apps record to the private DNS zone by using the following command:

Copy to Clipboard Toggle word wrap

az network private-dns record-set a add-record -g ${RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n *.apps -a ${PUBLIC_IP_ROUTER}

$ az network private-dns record-set a add-record -g ${RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n *.apps -a ${PUBLIC_IP_ROUTER}

If you prefer to add explicit domains instead of using a wildcard, you can create entries for each of the cluster’s current routes:

Copy to Clipboard Toggle word wrap

oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

$ oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

3.8.22. Completing an Azure installation on user-provisioned infrastructure

After you start the OpenShift Container Platform installation on Microsoft Azure user-provisioned infrastructure, you can monitor the cluster events until the cluster is ready.

Prerequisites

Deploy the bootstrap machine for an OpenShift Container Platform cluster on user-provisioned Azure infrastructure.
Install the oc CLI and log in.

Procedure

Complete the cluster installation:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install --dir=<installation_directory> wait-for install-complete
```
```
$ ./openshift-install --dir=<installation_directory> wait-for install-complete

```
```
INFO Waiting up to 30m0s for the cluster to initialize...
```
1
For <installation_directory>, specify the path to the directory that you stored the installation files in.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.

3.9. Uninstalling a cluster on Azure

You can remove a cluster that you deployed to Microsoft Azure.

3.9.1. Removing a cluster that uses installer-provisioned infrastructure

You can remove a cluster that uses installer-provisioned infrastructure from your cloud.

注意

Prerequisites

Have a copy of the installation program that you used to deploy the cluster.
Have the files that the installation program generated when you created your cluster.

Procedure

From the computer that you used to install the cluster, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install destroy cluster \
--dir=<installation_directory> --log-level=info
```
```
$ ./openshift-install destroy cluster \

1
For <installation_directory>, specify the path to the directory that you stored the installation files in.
2
To view different details, specify warn, debug, or error instead of info.
注意
You must specify the directory that contains the cluster definition files for your cluster. The installation program requires the metadata.json file in this directory to delete the cluster.
Optional: Delete the <installation_directory> directory and the OpenShift Container Platform installation program.

第 4 章 Installing on GCP

4.1. Configuring a GCP project

Before you can install OpenShift Container Platform, you must configure a Google Cloud Platform (GCP) project to host it.

4.1.1. Creating a GCP project

To install OpenShift Container Platform, you must create a project in your Google Cloud Platform (GCP) account to host the cluster.

Procedure

Create a project to host your OpenShift Container Platform cluster. See Creating and Managing Projects in the GCP documentation.
重要
Your GCP project must use the Premium Network Service Tier if you are using installer-provisioned infrastructure. The Standard Network Service Tier is not supported for clusters installed using the installation program. The installation program configures internal load balancing for the api-int.<cluster_name>.<base_domain> URL; the Premium Tier is required for internal load balancing.

4.1.2. Enabling API services in GCP

Your Google Cloud Platform (GCP) project requires access to several API services to complete OpenShift Container Platform installation.

Prerequisites

You created a project to host your cluster.

Procedure

Enable the following required API services in the project that hosts your cluster. See Enabling services in the GCP documentation.

表 4.1. Required API services
API service	Console service name
Compute Engine API	`compute.googleapis.com`
Google Cloud APIs	`cloudapis.googleapis.com`
Cloud Resource Manager API	`cloudresourcemanager.googleapis.com`
Google DNS API	`dns.googleapis.com`
IAM Service Account Credentials API	`iamcredentials.googleapis.com`
Identity and Access Management (IAM) API	`iam.googleapis.com`
Service Management API	`servicemanagement.googleapis.com`
Service Usage API	`serviceusage.googleapis.com`
Google Cloud Storage JSON API	`storage-api.googleapis.com`
Cloud Storage	`storage-component.googleapis.com`

4.1.3. Configuring DNS for GCP

To install OpenShift Container Platform, the Google Cloud Platform (GCP) account you use must have a dedicated public hosted zone in the same project that you host the OpenShift Container Platform cluster. This zone must be authoritative for the domain. The DNS service provides cluster DNS resolution and name lookup for external connections to the cluster.

Procedure

Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through GCP or another source.
注意
If you purchase a new domain, it can take time for the relevant DNS changes to propagate. For more information about purchasing domains through Google, see Google Domains.
Create a public hosted zone for your domain or subdomain in your GCP project. See Creating public zones in the GCP documentation.
Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.
Extract the new authoritative name servers from the hosted zone records. See Look up your Cloud DNS name servers in the GCP documentation.
You typically have four name servers.
Update the registrar records for the name servers that your domain uses. For example, if you registered your domain to Google Domains, see the following topic in the Google Domains Help: How to switch to custom name servers.
If you migrated your root domain to Google Cloud DNS, migrate your DNS records. See Migrating to Cloud DNS in the GCP documentation.
If you use a subdomain, follow your company’s procedures to add its delegation records to the parent domain. This process might include a request to your company’s IT department or the division that controls the root domain and DNS services for your company.

4.1.4. GCP account limits

The OpenShift Container Platform cluster uses a number of Google Cloud Platform (GCP) components, but the default Quotas do not affect your ability to install a default OpenShift Container Platform cluster.

A default cluster, which contains three compute and three control plane machines, uses the following resources. Note that some resources are required only during the bootstrap process and are removed after the cluster deploys.

表 4.2. GCP resources used in a default cluster
Service	Component	Location	Total resources required	Resources removed after bootstrap
Service account	IAM	Global	5	0
Firewall rules	Compute	Global	11	1
Forwarding rules	Compute	Global	2	0
In-use global IP addresses	Compute	Global	4	1
Health checks	Compute	Global	3	0
Images	Compute	Global	1	0
Networks	Compute	Global	2	0
Static IP addresses	Compute	Region	4	1
Routers	Compute	Global	1	0
Routes	Compute	Global	2	0
Subnetworks	Compute	Global	2	0
Target pools	Compute	Global	3	0
CPUs	Compute	Region	28	4
Persistent disk SSD (GB)	Compute	Region	896	128

注意

If any of the quotas are insufficient during installation, the installation program displays an error that states both which quota was exceeded and the region.

Be sure to consider your actual cluster size, planned cluster growth, and any usage from other clusters that are associated with your account. The CPU, static IP addresses, and persistent disk SSD (storage) quotas are the ones that are most likely to be insufficient.

If you plan to deploy your cluster in one of the following regions, you will exceed the maximum storage quota and are likely to exceed the CPU quota limit:

asia-east2
asia-northeast2
asia-south1
australia-southeast1
europe-north1
europe-west2
europe-west3
europe-west6
northamerica-northeast1
southamerica-east1
us-west2

You can increase resource quotas from the GCP console, but you might need to file a support ticket. Be sure to plan your cluster size early so that you can allow time to resolve the support ticket before you install your OpenShift Container Platform cluster.

4.1.5. Creating a service account in GCP

OpenShift Container Platform requires a Google Cloud Platform (GCP) service account that provides authentication and authorization to access data in the Google APIs. If you do not have an existing IAM service account that contains the required roles in your project, you must create one.

Prerequisites

You created a project to host your cluster.

Procedure

Create a service account in the project that you use to host your OpenShift Container Platform cluster. See Creating a service account in the GCP documentation.
Grant the service account the appropriate permissions. You can either grant the individual permissions that follow or assign the Owner role to it. See Granting roles to a service account for specific resources.
注意
While making the service account an owner of the project is the easiest way to gain the required permissions, it means that service account has complete control over the project. You must determine if the risk that comes from offering that power is acceptable.
Create the service account key in JSON format. See Creating service account keys in the GCP documentation.
The service account key is required to create a cluster.

4.1.5.1. Required GCP permissions

When you attach the Owner role to the service account that you create, you grant that service account all permissions, including those that are required to install OpenShift Container Platform. To deploy an OpenShift Container Platform cluster, the service account requires the following permissions. If you deploy your cluster into an existing VPC, the service account does not require certain networking permissions, which are noted in the following lists:

Required roles for the installation program

Compute Admin
Security Admin
Service Account Admin
Service Account User
Storage Admin

Required roles for creating network resources during installation

DNS Administrator

Optional roles

For the cluster to create new limited credentials for its Operators, add the following role:

Service Account Key Admin

The roles are applied to the service accounts that the control plane and compute machines use:

表 4.3. GCP service account permissions
Account	Roles
Control Plane	`roles/compute.instanceAdmin`
	`roles/compute.networkAdmin`
	`roles/compute.securityAdmin`
	`roles/storage.admin`
	`roles/iam.serviceAccountUser`
Compute	`roles/compute.viewer`
Compute	`roles/storage.admin`

4.1.6. Supported GCP regions

You can deploy an OpenShift Container Platform cluster to the following Google Cloud Platform (GCP) regions:

asia-east1 (Changhua County, Taiwan)
asia-east2 (Hong Kong)
asia-northeast1 (Tokyo, Japan)
asia-northeast2 (Osaka, Japan)
asia-south1 (Mumbai, India)
asia-southeast1 (Jurong West, Singapore)
australia-southeast1 (Sydney, Australia)
europe-north1 (Hamina, Finland)
europe-west1 (St. Ghislain, Belgium)
europe-west2 (London, England, UK)
europe-west3 (Frankfurt, Germany)
europe-west4 (Eemshaven, Netherlands)
europe-west6 (Zürich, Switzerland)
northamerica-northeast1 (Montréal, Québec, Canada)
southamerica-east1 (São Paulo, Brazil)
us-central1 (Council Bluffs, Iowa, USA)
us-east1 (Moncks Corner, South Carolina, USA)
us-east4 (Ashburn, Northern Virginia, USA)
us-west1 (The Dalles, Oregon, USA)
us-west2 (Los Angeles, California, USA)

grep -l "apiVersion: cloudcredential.openshift.io" * | xargs cat

$ grep -l "apiVersion: cloudcredential.openshift.io" * | xargs cat

注意

In a future OpenShift Container Platform release, there will be a new oc adm release command to scan for the CredentialsRequests and display them.

This displays the details for each request. Remember to ignore any CredentialsRequests where the spec.providerSpec.kind does not match the cloud provider you are installing to.

Sample CredentialsRequest object

Create YAML files for secrets in the openshift-install manifests directory that you generated previously. The secrets must be stored using the namespace and secret name defined in each request.spec.secretRef. The format for the secret data varies for each cloud provider.
Proceed with cluster creation:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
openshift-install create cluster --dir=mycluster
```
```
$ openshift-install create cluster --dir=mycluster
```
重要
Before performing an upgrade, you might need to adjust your credentials if permissions have changed in the next release. In the future, the Cloud Credential Operator might prevent you from upgrading until you have indicated that you have addressed updated permissions.

4.2.2. Admin credentials root secret format

The format for the secret varies by cloud, and is also used for each CredentialsRequest secret.

Google Cloud Platform (GCP) secret format

Copy to Clipboard Toggle word wrap

apiVersion: v1
kind: Secret
metadata:
  namespace: kube-system
  name: gcp-credentials
stringData:
  service_account.json: <ServiceAccount>

apiVersion: v1
kind: Secret
metadata:
  namespace: kube-system
  name: gcp-credentials
stringData:
  service_account.json: <ServiceAccount>

4.2.2.1. Upgrades

4.2.3. Mint Mode

Mint Mode is supported for AWS, GCP, and Azure.

The benefits of Mint Mode include:

Each cluster component only has the permissions it requires.
Automatic, on-going reconciliation for cloud credentials including upgrades, which might require additional credentials or permissions.

One drawback is that Mint Mode requires admin credential storage in a cluster kube-system secret.

4.3. Installing a cluster quickly on GCP

In OpenShift Container Platform version 4.5, you can install a cluster on Google Cloud Platform (GCP) that uses the default configuration options.

4.3.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure a GCP account to host the cluster.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

4.3.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

4.3.3. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"

```
$ eval "$(ssh-agent -s)"
```
Example output

```
$ gcloud auth list
```

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

4.3.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

4.3.5. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Remove any existing GCP credentials that do not use the service account key for the GCP account that you configured for your cluster and that are stored in the following locations:
- The GOOGLE_CREDENTIALS, GOOGLE_CLOUD_KEYFILE_JSON, or GCLOUD_KEYFILE_JSON environment variables
- The ~/.gcp/osServiceAccount.json file
- The gcloud cli default credentials
Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the directory name to store the files that the installation program creates.
2
To view different installation details, specify warn, debug, or error instead of info.
重要
Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
Provide values at the prompts:
1. Optional: Select an SSH key to use to access your cluster machines.
  注意
  For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
2. Select gcp as the platform to target.
3. If you have not configured the service account key for your GCP account on your computer, you must obtain it from GCP and paste the contents of the file or enter the absolute path to the file.
4. Select the project ID to provision the cluster in. The default value is specified by the service account that you configured.
5. Select the region to deploy the cluster to.
6. Select the base domain to deploy the cluster to. The base domain corresponds to the public DNS zone that you created for your cluster.
7. Enter a descriptive name for your cluster. If you provide a name that is longer than 6 characters, only the first 6 characters will be used in the infrastructure ID that is generated from the cluster name.
8. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.
Optional: You can reduce the number of permissions for the service account that you used to install the cluster.
- If you assigned the Owner role to your service account, you can remove that role and replace it with the Viewer role.
- If you included the Service Account Key Admin role, you can remove it.

4.3.8. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

4.4. Installing a cluster on GCP with customizations

In OpenShift Container Platform version 4.5, you can install a customized cluster on infrastructure that the installation program provisions on Google Cloud Platform (GCP). To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

4.4.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure a GCP account to host the cluster.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.

Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

4.4.3. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \

1 8 9 10 11: Required. The installation program prompts you for this value.
2 5: If you do not provide these parameters and values, the installation program provides the default value.
3 6: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4 7: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.
重要
If you disable simultaneous multithreading, ensure that your capacity planning accounts for the dramatically decreased machine performance. Use larger machine types, such as n1-standard-8, for your machines if you disable simultaneous multithreading.
12: Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
13: You can optionally provide the sshKey value that you use to access the machines in your cluster.
注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.

4.4.6. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Remove any existing GCP credentials that do not use the service account key for the GCP account that you configured for your cluster and that are stored in the following locations:
- The GOOGLE_CREDENTIALS, GOOGLE_CLOUD_KEYFILE_JSON, or GCLOUD_KEYFILE_JSON environment variables
- The ~/.gcp/osServiceAccount.json file
- The gcloud cli default credentials
Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.
Optional: You can reduce the number of permissions for the service account that you used to install the cluster.
- If you assigned the Owner role to your service account, you can remove that role and replace it with the Viewer role.
- If you included the Service Account Key Admin role, you can remove it.

4.4.9. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

4.5. Installing a cluster on GCP with network customizations

In OpenShift Container Platform version 4.5, you can install a cluster with a customized network configuration on infrastructure that the installation program provisions on Google Cloud Platform (GCP). By customizing your network configuration, your cluster can coexist with existing IP address allocations in your environment and integrate with existing MTU and VXLAN configurations. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

You must set most of the network configuration parameters during installation, and you can modify only kubeProxy configuration parameters in a running cluster.

4.5.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure a GCP account to host the cluster.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

4.5.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

4.5.3. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:

gcloud auth list
```
```
$ gcloud auth list
```

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

4.5.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

4.5.5. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Google Cloud Platform (GCP).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select gcp as the platform to target.
  3. If you have not configured the service account key for your GCP account on your computer, you must obtain it from GCP and paste the contents of the file or enter the absolute path to the file.
  4. Select the project ID to provision the cluster in. The default value is specified by the service account that you configured.
  5. Select the region to deploy the cluster to.
  6. Select the base domain to deploy the cluster to. The base domain corresponds to the public DNS zone that you created for your cluster.
  7. Enter a descriptive name for your cluster.
  8. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

4.5.5.1. Installation configuration parameters

`controlPlane.platform`	Required if you use `controlPlane`. Use this parameter to specify the cloud provider that hosts the control plane machines. This parameter value must match the `compute.platform` parameter value.	`aws`, `azure`, `gcp`, `openstack`, `ovirt`, `vsphere`, or `{}`
`controlPlane.replicas`	The number of control plane machines to provision.	The only supported value is `3`, which is the default value.
`fips`	Enable or disable FIPS mode. The default is `false` (disabled). If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead. 注意 If you are using Azure File storage, you cannot enable FIPS mode.	`false` or `true`
`imageContentSources`	Sources and repositories for the release-image content.	Array of objects. Includes a `source` and, optionally, `mirrors`, as described in the following rows of this table.
`imageContentSources.source`	Required if you use `imageContentSources`. Specify the repository that users refer to, for example, in image pull specifications.	String
`imageContentSources.mirrors`	Specify one or more repositories that may also contain the same images.	Array of strings
`publish`	How to publish or expose the user-facing endpoints of your cluster, such as the Kubernetes API, OpenShift routes.	`Internal` or `External`. To deploy a private cluster, which cannot be accessed from the internet, set `publish` to `Internal`. The default value is `External`. `Internal` or `External`. The default value is `External`. Setting this field to `Internal` is not supported on non-cloud platforms. 重要 If the value of the field is set to `Internal`, the cluster will become non-functional. For more information, refer to BZ#1953035.
`sshKey`	The SSH key to authenticate access to your cluster machines. 注意 For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your `ssh-agent` process uses.	For example, `sshKey: ssh-ed25519 AAAA..`.

注意

You cannot modify these parameters in the install-config.yaml file after installation.

表 4.12. Required network parameters
Parameter	Description	Value
`networking.networkType`	The default Container Network Interface (CNI) network provider plug-in to deploy. The `OpenShiftSDN` plug-in is the only plug-in supported in OpenShift Container Platform 4.5. The `OVNKubernetes` plug-in is available as a Technology Preview in OpenShift Container Platform 4.5.	Either `OpenShiftSDN` or `OVNKubernetes`. The default value is `OpenShiftSDN`.
`networking.clusterNetwork[].cidr`	A block of IP addresses from which pod IP addresses are allocated. The `OpenShiftSDN` network plug-in supports multiple cluster networks. The address blocks for multiple cluster networks must not overlap. Select address pools large enough to fit your anticipated workload.	An IP address allocation in CIDR format. The default value is `10.128.0.0/14`.
`networking.clusterNetwork[].hostPrefix`	The subnet prefix length to assign to each individual node. For example, if `hostPrefix` is set to `23`, then each node is assigned a `/23` subnet out of the given `cidr`, allowing for 510 (2^(32 - 23) - 2) pod IP addresses.	A subnet prefix. The default value is `23`.
`networking.serviceNetwork[]`	A block of IP addresses for services. `OpenShiftSDN` allows only one `serviceNetwork` block. The address block must not overlap with any other network block.	An IP address allocation in CIDR format. The default value is `172.30.0.0/16`.

2 5 9: If you do not provide these parameters and values, the installation program provides the default value.
3 6: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4 7: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.
重要
If you disable simultaneous multithreading, ensure that your capacity planning accounts for the dramatically decreased machine performance. Use larger machine types, such as n1-standard-8, for your machines if you disable simultaneous multithreading.
13: Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
14: You can optionally provide the sshKey value that you use to access the machines in your cluster.
注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.

4.5.6. Modifying advanced network configuration parameters

重要

Modifying the OpenShift Container Platform manifest files created by the installation program is not supported. Applying a manifest file that you create, as in the following procedure, is supported.

Prerequisites

Create the install-config.yaml file and complete any modifications to it.

4.5.8. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```

```
    --log-level=info 
```
2
1
For <installation_directory>, specify the
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.

4.5.9. Installing the CLI by downloading the binary

You can install the OpenShift CLI (oc) in order to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS.

4.5.11. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

4.6. Installing a cluster on GCP in a restricted network

In OpenShift Container Platform 4.5, you can install a cluster on Google Cloud Platform (GCP) in a restricted network by creating an internal mirror of the installation release content on an existing Google Virtual Private Cloud (VPC).

重要

You can install an OpenShift Container Platform cluster by using mirrored installation release content, but your cluster will require internet access to use the GCP APIs.

4.6.1. Prerequisites

You mirrored the images for a disconnected installation to your registry and obtained the imageContentSources data for your version of OpenShift Container Platform.
重要
Because the installation media is on the mirror host, you can use that computer to complete all installation steps.
You have an existing VPC in GCP. While installing a cluster in a restricted network that uses installer-provisioned infrastructure, you cannot use the installer-provisioned VPC. You must use a user-provisioned VPC that satisfies one of the following requirements:
- Contains the mirror registry
- Has firewall rules or a peering connection to access the mirror registry hosted elsewhere
You reviewed details about the OpenShift Container Platform installation and update processes.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to. While you might need to grant access to more sites, you must grant access to *.googleapis.com and accounts.google.com.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

4.6.2. About installations in restricted networks

4.6.2.1. Additional limits

Clusters in restricted networks have the following additional limitations and restrictions:

The ClusterVersion status includes an Unable to retrieve available updates error.
By default, you cannot use the contents of the Developer Catalog because you cannot access the required image stream tags.

4.6.3. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

Additional resources

See About remote health monitoring for more information about the Telemetry service

4.6.4. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

4.6.5. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Google Cloud Platform (GCP).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster. For a restricted network installation, these files are on your bastion host.
Have the imageContentSources values that were generated during mirror registry creation.
Obtain the contents of the certificate for your mirror registry.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select gcp as the platform to target.
  3. If you have not configured the service account key for your GCP account on your computer, you must obtain it from GCP and paste the contents of the file or enter the absolute path to the file.
  4. Select the project ID to provision the cluster in. The default value is specified by the service account that you configured.
  5. Select the region to deploy the cluster to.
  6. Select the base domain to deploy the cluster to. The base domain corresponds to the public DNS zone that you created for your cluster.
  7. Enter a descriptive name for your cluster.
  8. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Edit the install-config.yaml file to provide the additional information that is required for an installation in a restricted network.
1. Update the pullSecret value to contain the authentication information for your registry:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
pullSecret: '{"auths":{"<bastion_host_name>:5000": {"auth": "<credentials>","email": "you@example.com"}}}'
```
```
pullSecret: '{"auths":{"<bastion_host_name>:5000": {"auth": "<credentials>","email": "you@example.com"}}}'
```
  For <bastion_host_name>, specify the registry domain name that you specified in the certificate for your mirror registry, and for <credentials>, specify the base64-encoded user name and password for your mirror registry.
2. Add the additionalTrustBundle parameter and value.
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
additionalTrustBundle: |
  -----BEGIN CERTIFICATE-----
  ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
  -----END CERTIFICATE-----
```
```
additionalTrustBundle: |
  -----BEGIN CERTIFICATE-----
  ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
  -----END CERTIFICATE-----
```
  The value must be the contents of the certificate file that you used for your mirror registry, which can be an existing, trusted certificate authority or the self-signed certificate that you generated for the mirror registry.
3. Define the network and subnets for the VPC to install the cluster in under the parent platform.gcp field:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
network: <existing_vpc>
controlPlaneSubnet: <control_plane_subnet>
computeSubnet: <compute_subnet>
```
```
network: <existing_vpc>
controlPlaneSubnet: <control_plane_subnet>
computeSubnet: <compute_subnet>
```
  For platform.gcp.network, specify the name for the existing Google VPC. For platform.gcp.controlPlaneSubnet and platform.gcp.computeSubnet, specify the existing subnets to deploy the control plane machines and compute machines, respectively.
4. Add the image content resources, which look like this excerpt:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
imageContentSources:
- mirrors:
  - <bastion_host_name>:5000/<repo_name>/release
  source: quay.example.com/openshift-release-dev/ocp-release
- mirrors:
  - <bastion_host_name>:5000/<repo_name>/release
  source: registry.example.com/ocp/release
```
```
imageContentSources:
- mirrors:
  - <bastion_host_name>:5000/<repo_name>/release
  source: quay.example.com/openshift-release-dev/ocp-release
- mirrors:
  - <bastion_host_name>:5000/<repo_name>/release
  source: registry.example.com/ocp/release
```
  To complete these values, use the imageContentSources that you recorded during mirror registry creation.
Make any other modifications to the install-config.yaml file that you require. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

Only one control plane pool is used.
4 7: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.
重要

: Provide the imageContentSources section from the output of the command to mirror the repository.

4.6.5.3. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----

```
```
apiVersion: v1
baseDomain: my.domain.com

```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

4.6.6. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Remove any existing GCP credentials that do not use the service account key for the GCP account that you configured for your cluster and that are stored in the following locations:
- The GOOGLE_CREDENTIALS, GOOGLE_CLOUD_KEYFILE_JSON, or GCLOUD_KEYFILE_JSON environment variables
- The ~/.gcp/osServiceAccount.json file
- The gcloud cli default credentials
Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.
Optional: You can reduce the number of permissions for the service account that you used to install the cluster.
- If you assigned the Owner role to your service account, you can remove that role and replace it with the Viewer role.
- If you included the Service Account Key Admin role, you can remove it.

4.6.9. Next steps

Customize your cluster.
Configure image streams for the Cluster Samples Operator and the must-gather tool.
Learn how to use Operator Lifecycle Manager (OLM) on restricted networks.
If the mirror registry that you used to install your cluster has a trusted CA, add it to the cluster by configuring additional trust stores.
If necessary, you can opt out of remote health reporting.

4.7. Installing a cluster on GCP into an existing VPC

In OpenShift Container Platform version 4.5, you can install a cluster into an existing Virtual Private Cloud (VPC) on Google Cloud Platform (GCP). The installation program provisions the rest of the required infrastructure, which you can further customize. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

4.7.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure a GCP account to host the cluster.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

4.7.2. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

4.7.3. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

4.7.4. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

4.7.5. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Google Cloud Platform (GCP).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select gcp as the platform to target.
  3. If you have not configured the service account key for your GCP account on your computer, you must obtain it from GCP and paste the contents of the file or enter the absolute path to the file.
  4. Select the project ID to provision the cluster in. The default value is specified by the service account that you configured.
  5. Select the region to deploy the cluster to.
  6. Select the base domain to deploy the cluster to. The base domain corresponds to the public DNS zone that you created for your cluster.
  7. Enter a descriptive name for your cluster.
  8. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

1 8 9 10 14: Required. The installation program prompts you for this value.
2 5: If you do not provide these parameters and values, the installation program provides the default value.
3 6: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4 7: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.

注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.

4.7.5.3. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```

```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

4.7.6. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Remove any existing GCP credentials that do not use the service account key for the GCP account that you configured for your cluster and that are stored in the following locations:
- The GOOGLE_CREDENTIALS, GOOGLE_CLOUD_KEYFILE_JSON, or GCLOUD_KEYFILE_JSON environment variables
- The ~/.gcp/osServiceAccount.json file
- The gcloud cli default credentials
Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the location of your customized ./install-config.yaml file.
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.
Optional: You can reduce the number of permissions for the service account that you used to install the cluster.

4.7.9. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

4.8. Installing a private cluster on GCP

In OpenShift Container Platform version 4.5, you can install a private cluster into an existing VPC on Google Cloud Platform (GCP). The installation program provisions the rest of the required infrastructure, which you can further customize. To customize the installation, you modify parameters in the install-config.yaml file before you install the cluster.

4.8.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
Configure a GCP account to host the cluster.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

4.8.2. Private clusters

To deploy a private cluster, you must use existing networking that meets your requirements. Your cluster resources might be shared between other clusters on the network.

4.8.2.1. Private clusters in GCP

To create a private cluster on Google Cloud Platform (GCP), you must provide an existing private VPC and subnets to host the cluster. The installation program must also be able to resolve the DNS records that the cluster requires. The installation program configures the Ingress Operator and API server for only internal traffic.

The cluster still requires access to Internet to access the GCP APIs.

The following items are not required or created when you install a private cluster:

Public subnets
Public network load balancers, which support public ingress
A public DNS zone that matches the baseDomain for the cluster

The installation program does use the baseDomain that you specify to create a private DNS zone and the required records for the cluster. The cluster is configured so that the Operators do not create public records for the cluster and all cluster machines are placed in the private subnets that you specify.

Because it is not possible to limit access to external load balancers based on source tags, the private cluster uses only internal load balancers to allow access to internal instances.

The internal load balancer relies on instance groups rather than the target pools that the network load balancers use. The installation program creates instance groups for each zone, even if there is no instance in that group.

The cluster IP address is internal only.
One forwarding rule manages both the Kubernetes API and machine config server ports.
The backend service is comprised of each zone’s instance group and, while it exists, the bootstrap instance group.
The firewall uses a single rule that is based on only internal source ranges.

4.8.2.1.1. Limitations

No health check for the Machine config server, /healthz, runs because of a difference in load balancer functionality. Two internal load balancers cannot share a single IP address, but two network load balancers can share a single external IP address. Instead, the health of an instance is determined entirely by the /readyz check on port 6443.

4.8.3. About using a custom VPC

In OpenShift Container Platform 4.5, you can deploy a cluster into an existing VPC in Google Cloud Platform (GCP). If you do, you must also use existing subnets within the VPC and routing rules.

By deploying OpenShift Container Platform into an existing GCP VPC, you might be able to avoid limit constraints in new accounts or more easily abide by the operational constraints that your company’s guidelines set. This is a good option to use if you cannot obtain the infrastructure creation permissions that are required to create the VPC yourself.

4.8.3.1. Requirements for using your VPC

The installation program will no longer create the following components:

VPC
Subnets
Cloud router
Cloud NAT
NAT IP addresses

Your VPC and subnets must meet the following characteristics:

The VPC must be in the same GCP project that you deploy the OpenShift Container Platform cluster to.
To allow access to the Internet from the control plane and compute machines, you must configure cloud NAT on the subnets to allow egress to it. These machines do not have a public address. Even if you do not require access to the Internet, you must allow egress to the VPC network to obtain the installation program and images. Because multiple cloud NATs cannot be configured on the shared subnets, the installation program cannot configure it.

To ensure that the subnets that you provide are suitable, the installation program confirms the following data:

All the subnets that you specify exist and belong to the VPC that you specified.
The subnet CIDRs belong to the machine CIDR.
You must provide a subnet to deploy the cluster control plane and compute machines to. You can use the same subnet for both machine types.

If you destroy a cluster that uses an existing VPC, the VPC is not deleted.

4.8.3.2. Division of permissions

Starting with OpenShift Container Platform 4.3, you do not need all of the permissions that are required for an installation program-provisioned infrastructure cluster to deploy a cluster. This change mimics the division of permissions that you might have at your company: some individuals can create different resources in your clouds than others. For example, you might be able to create application-specific items, like instances, buckets, and load balancers, but not networking-related components such as VPCs, subnets, or Ingress rules.

The GCP credentials that you use when you create your cluster do not need the networking permissions that are required to make VPCs and core networking components within the VPC, such as subnets, routing tables, internet gateways, NAT, and VPN. You still need permission to make the application resources that the machines within the cluster require, such as load balancers, security groups, storage, and nodes.

4.8.3.3. Isolation between clusters

If you deploy OpenShift Container Platform to an existing network, the isolation of cluster services is preserved by firewall rules that reference the machines in your cluster by the cluster’s infrastructure ID. Only traffic within the cluster is allowed.

If you deploy multiple clusters to the same VPC, the following components might share access between clusters:

The API, which is globally available with an external publishing strategy or available throughout the network in an internal publishing strategy
Debugging tools, such as ports on VM instances that are open to the machine CIDR for SSH and ICMP access

4.8.4. Internet and Telemetry access for OpenShift Container Platform

You must have Internet access to:

Access the Red Hat OpenShift Cluster Manager page to download the installation program and perform subscription management. If the cluster has Internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.

重要

4.8.5. Generating an SSH private key and adding it to the agent

注意

In a production environment, you require disaster recovery and debugging.

You can use this key to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user’s ~/.ssh/authorized_keys list.

注意

You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs.

Procedure

If you do not have an SSH key that is configured for password-less authentication on your computer, create one. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name>
```
```
$ ssh-keygen -t ed25519 -N '' \
    -f <path>/<file_name> 
```
1
1
Specify the path and file name, such as ~/.ssh/id_rsa, of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory.
Running this command generates an SSH key that does not require a password in the location that you specified.
注意
If you plan to install an OpenShift Container Platform cluster that uses FIPS Validated / Modules in Process cryptographic libraries on the x86_64 architecture, do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm.
Start the ssh-agent process as a background task:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
eval "$(ssh-agent -s)"
```
```
$ eval "$(ssh-agent -s)"
```
Example output
Copy to Clipboard Copied! Toggle word wrap Toggle overflow

```
```
Agent pid 31874
```
Add your SSH private key to the ssh-agent:

ssh-add <path>/<file_name>
```
```
$ ssh-add <path>/<file_name> 
```

Specify the path and file name for your SSH private key, such as ~/.ssh/id_rsa
Set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the full path to your service account private key file.
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
export GOOGLE_APPLICATION_CREDENTIALS="<your_service_account_file>"
```

```
$ gcloud auth list
```

Next steps

When you install OpenShift Container Platform, provide the SSH public key to the installation program.

4.8.6. Obtaining the installation program

Before you install OpenShift Container Platform, download the installation file on a local computer.

Prerequisites

You must install the cluster from a computer that uses Linux or macOS.
You need 500 MB of local disk space to download the installation program.

Procedure

Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.
重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.
重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
tar xvf <installation_program>.tar.gz
```
```
$ tar xvf <installation_program>.tar.gz
```
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a .txt file. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.

4.8.7. Manually creating the installation configuration file

Prerequisites

Obtain the OpenShift Container Platform installation program and the access token for your cluster.

Procedure

Create an installation directory to store your required installation assets in:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
mkdir <installation_directory>
```
```
$ mkdir <installation_directory>
```
重要
You must create a directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
Customize the following install-config.yaml file template and save it in the <installation_directory>.
注意
You must name this configuration file install-config.yaml.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the next step of the installation process. You must back it up now.

4.8.7.1. Installation configuration parameters

If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
: You can optionally provide the sshKey value that you use to access the machines in your cluster.
注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
: How to publish the user-facing endpoints of your cluster. Set publish to Internal to deploy a private cluster, which cannot be accessed from the Internet. The default value is External.

4.8.7.3. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```

```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

4.8.8. Deploying the cluster

You can install OpenShift Container Platform on a compatible cloud platform.

重要

You can run the create cluster command of the installation program only once, during initial installation.

Prerequisites

Configure an account with the cloud platform that hosts your cluster.
Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Run the installation program:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create cluster --dir=<installation_directory> \
    --log-level=info
```
```
$ ./openshift-install create cluster --dir=<installation_directory> \ 
```
1
```
    --log-level=info 
```
2
1
For <installation_directory>, specify the
2
To view different installation details, specify warn, debug, or error instead of info.
注意
If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed.
When the cluster deployment completes, directions for accessing your cluster, including a link to its web console and credentials for the kubeadmin user, display in your terminal.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.
重要
You must not delete the installation program or the files that the installation program creates. Both are required to delete the cluster.

4.8.9. Installing the CLI by downloading the binary

You can install the OpenShift CLI (oc) in order to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS.

4.8.11. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

4.9. Installing a cluster on user-provisioned infrastructure in GCP by using Deployment Manager templates

In OpenShift Container Platform version 4.5, you can install a cluster on Google Cloud Platform (GCP) that uses infrastructure that you provide.

The steps for performing a user-provided infrastructure install are outlined here. Several Deployment Manager templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods.

重要

The steps for performing a user-provisioned infrastructure installation are provided as an example only. Installing a cluster with infrastructure you provide requires knowledge of the cloud provider and the installation process of OpenShift Container Platform. Several Deployment Manager templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods; the templates are just an example.

4.9.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
If you use a firewall and plan to use telemetry, you must configure the firewall to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.
注意
Be sure to also review this site list if you are configuring a proxy.

4.9.2. Certificate signing requests management

4.9.3. Configuring your GCP project

Before you can install OpenShift Container Platform, you must configure a Google Cloud Platform (GCP) project to host it.

4.9.3.1. Creating a GCP project

To install OpenShift Container Platform, you must create a project in your Google Cloud Platform (GCP) account to host the cluster.

Procedure

Create a project to host your OpenShift Container Platform cluster. See Creating and Managing Projects in the GCP documentation.
重要
Your GCP project must use the Premium Network Service Tier if you are using installer-provisioned infrastructure. The Standard Network Service Tier is not supported for clusters installed using the installation program. The installation program configures internal load balancing for the api-int.<cluster_name>.<base_domain> URL; the Premium Tier is required for internal load balancing.

4.9.3.2. Enabling API services in GCP

Your Google Cloud Platform (GCP) project requires access to several API services to complete OpenShift Container Platform installation.

Prerequisites

You created a project to host your cluster.

Procedure

Enable the following required API services in the project that hosts your cluster. See Enabling services in the GCP documentation.

表 4.25. Required API services
API service	Console service name
Cloud Deployment Manager V2 API	`deploymentmanager.googleapis.com`
Compute Engine API	`compute.googleapis.com`
Google Cloud APIs	`cloudapis.googleapis.com`
Cloud Resource Manager API	`cloudresourcemanager.googleapis.com`
Google DNS API	`dns.googleapis.com`
IAM Service Account Credentials API	`iamcredentials.googleapis.com`
Identity and Access Management (IAM) API	`iam.googleapis.com`
Service Management API	`servicemanagement.googleapis.com`
Service Usage API	`serviceusage.googleapis.com`
Google Cloud Storage JSON API	`storage-api.googleapis.com`
Cloud Storage	`storage-component.googleapis.com`

4.9.3.3. Configuring DNS for GCP

Procedure

Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through GCP or another source.
注意
If you purchase a new domain, it can take time for the relevant DNS changes to propagate. For more information about purchasing domains through Google, see Google Domains.
Create a public hosted zone for your domain or subdomain in your GCP project. See Creating public zones in the GCP documentation.
Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.
Extract the new authoritative name servers from the hosted zone records. See Look up your Cloud DNS name servers in the GCP documentation.
You typically have four name servers.
Update the registrar records for the name servers that your domain uses. For example, if you registered your domain to Google Domains, see the following topic in the Google Domains Help: How to switch to custom name servers.
If you migrated your root domain to Google Cloud DNS, migrate your DNS records. See Migrating to Cloud DNS in the GCP documentation.
If you use a subdomain, follow your company’s procedures to add its delegation records to the parent domain. This process might include a request to your company’s IT department or the division that controls the root domain and DNS services for your company.

4.9.3.4. GCP account limits

表 4.26. GCP resources used in a default cluster
Service	Component	Location	Total resources required	Resources removed after bootstrap
Service account	IAM	Global	5	0
Firewall rules	Networking	Global	11	1
Forwarding rules	Compute	Global	2	0
Health checks	Compute	Global	2	0
Images	Compute	Global	1	0
Networks	Networking	Global	1	0
Routers	Networking	Global	1	0
Routes	Networking	Global	2	0
Subnetworks	Compute	Global	2	0
Target pools	Networking	Global	2	0

注意

If any of the quotas are insufficient during installation, the installation program displays an error that states both which quota was exceeded and the region.

If you plan to deploy your cluster in one of the following regions, you will exceed the maximum storage quota and are likely to exceed the CPU quota limit:

asia-east2
asia-northeast2
asia-south1
australia-southeast1
europe-north1
europe-west2
europe-west3
europe-west6
northamerica-northeast1
southamerica-east1
us-west2

4.9.3.5. Creating a service account in GCP

Prerequisites

You created a project to host your cluster.

Procedure

Create a service account in the project that you use to host your OpenShift Container Platform cluster. See Creating a service account in the GCP documentation.
Grant the service account the appropriate permissions. You can either grant the individual permissions that follow or assign the Owner role to it. See Granting roles to a service account for specific resources.
注意
While making the service account an owner of the project is the easiest way to gain the required permissions, it means that service account has complete control over the project. You must determine if the risk that comes from offering that power is acceptable.
Create the service account key in JSON format. See Creating service account keys in the GCP documentation.
The service account key is required to create a cluster.

4.9.3.5.1. Required GCP permissions

Required roles for the installation program

Compute Admin
Security Admin
Service Account Admin
Service Account User

us-west2 (Los Angeles, California, USA)

4.9.3.7. Installing and configuring CLI tools for GCP

To install OpenShift Container Platform on Google Cloud Platform (GCP) using user-provisioned infrastructure, you must install and configure the CLI tools for GCP.

Prerequisites

You created a project to host your cluster.
You created a service account and granted it the required permissions.

Procedure

Install the following binaries in $PATH:
- gcloud
- gsutil
See Install the latest Cloud SDK version in the GCP documentation.
Authenticate using the gcloud tool with your configured service account.
See Authorizing with a service account in the GCP documentation.

4.9.4. Creating the installation files for GCP

To install OpenShift Container Platform on Google Cloud Platform (GCP) using user-provisioned infrastructure, you must generate the files that the installation program needs to deploy your cluster and modify them so that the cluster creates only the machines that it will use. You generate and customize the install-config.yaml file, Kubernetes manifests, and Ignition config files.

4.9.4.1. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Google Cloud Platform (GCP).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select gcp as the platform to target.
  3. If you have not configured the service account key for your GCP account on your computer, you must obtain it from GCP and paste the contents of the file or enter the absolute path to the file.
  4. Select the project ID to provision the cluster in. The default value is specified by the service account that you configured.
  5. Select the region to deploy the cluster to.
  6. Select the base domain to deploy the cluster to. The base domain corresponds to the public DNS zone that you created for your cluster.
  7. Enter a descriptive name for your cluster.
  8. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
3. Optional: If you do not want the cluster to provision compute machines, empty the compute pool by editing the resulting install-config.yaml file to set replicas to 0 for the compute pool:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
compute:
- hyperthreading: Enabled
  name: worker
  platform: {}
  replicas: 0 
```
```
compute:
- hyperthreading: Enabled
  name: worker
  platform: {}
  replicas: 0 
```
  1
  1
  Set to 0.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

4.9.4.2. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...

```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```

```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

4.9.4.3. Creating the Kubernetes manifest and Ignition config files

重要

Prerequisites

Obtain the OpenShift Container Platform installation program.
Create the install-config.yaml installation configuration file.

Procedure

Generate the Kubernetes manifests for the cluster:

Copy to Clipboard Toggle word wrap

./openshift-install create manifests --dir=<installation_directory>

$ ./openshift-install create manifests --dir=<installation_directory>

Example output

Copy to Clipboard Toggle word wrap

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

1: For <installation_directory>, specify the installation directory that contains the install-config.yaml file you created.

Because you create your own compute machines later in the installation process, you can safely ignore this warning.

Remove the Kubernetes manifest files that define the control plane machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
By removing these files, you prevent the cluster from automatically generating control plane machines.
Optional: If you do not want the cluster to provision compute machines, remove the Kubernetes manifest files that define the worker machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
Because you create and manage the worker machines yourself, you do not need to initialize these machines.
Modify the <installation_directory>/manifests/cluster-scheduler-02-config.yml Kubernetes manifest file to prevent pods from being scheduled on the control plane machines:
1. Open the <installation_directory>/manifests/cluster-scheduler-02-config.yml file.
2. Locate the mastersSchedulable parameter and set its value to False.
3. Save and exit the file.

4.9.5. Exporting common variables

4.9.5.1. Extracting the infrastructure name

The Ignition config files contain a unique cluster identifier that you can use to uniquely identify your cluster in Google Cloud Platform (GCP). The provided Deployment Manager templates contain references to this infrastructure name, so you must extract it.

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.
Generate the Ignition config files for your cluster.
Install the jq package.

Procedure

To extract and view the infrastructure name from the Ignition config file metadata, run the following command:

4.9.6. Creating a VPC in GCP

You must create a VPC in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. You can customize the VPC to meet your requirements. One way to create the VPC is to modify the provided Deployment Manager template.

注意

If you do not use the provided Deployment Manager template to create your GCP infrastructure, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.

Procedure

Copy the template from the Deployment Manager template for the VPC section of this topic and save it as 01_vpc.py on your computer. This template describes the VPC that your cluster requires.

Create a 01_vpc.yaml resource definition file:

Copy to Clipboard Toggle word wrap

cat <<EOF >01_vpc.yaml
imports:
- path: 01_vpc.py

resources:
- name: cluster-vpc
  type: 01_vpc.py
  properties:
    infra_id: '${INFRA_ID}'
    region: '${REGION}'
    master_subnet_cidr: '${MASTER_SUBNET_CIDR}'
    worker_subnet_cidr: '${WORKER_SUBNET_CIDR}'
EOF

$ cat <<EOF >01_vpc.yaml
imports:
- path: 01_vpc.py

resources:
- name: cluster-vpc
  type: 01_vpc.py
  properties:
    infra_id: '${INFRA_ID}'


    region: '${REGION}'


    master_subnet_cidr: '${MASTER_SUBNET_CIDR}'


    worker_subnet_cidr: '${WORKER_SUBNET_CIDR}'

EOF

1: infra_id is the INFRA_ID infrastructure name from the extraction step.
2: region is the region to deploy the cluster into, for example us-central1.
3: master_subnet_cidr is the CIDR for the master subnet, for example 10.0.0.0/19.
4: worker_subnet_cidr is the CIDR for the worker subnet, for example 10.0.32.0/19.

4.9.7. Networking requirements for user-provisioned infrastructure

All the Red Hat Enterprise Linux CoreOS (RHCOS) machines require network in initramfs during boot to fetch Ignition config from the machine config server.

You must configure the network connectivity between machines to allow cluster components to communicate. Each machine must be able to resolve the host names of all other machines in the cluster.

表 4.28. All machines to all machines
Protocol	Port	Description
ICMP	N/A	Network reachability tests
TCP	`1936`	Metrics
	`9000`-`9999`	Host level services, including the node exporter on ports `9100`-`9101` and the Cluster Version Operator on port `9099`.
	`10250`-`10259`	The default ports that Kubernetes reserves
	`10256`	openshift-sdn

Network topology requirements

The infrastructure that you provision for your cluster must meet the following network topology requirements.

重要

OpenShift Container Platform requires all nodes to have internet access to pull images for platform containers and provide telemetry data to Red Hat.

Load balancers

Before you install OpenShift Container Platform, you must provision two load balancers that meet the following requirements:

API load balancer: Provides a common endpoint for users, both human and machine, to interact with and configure the platform. Configure the following conditions:

Layer 4 load balancing only. This can be referred to as Raw TCP, SSL Passthrough, or SSL Bridge mode. If you use SSL Bridge mode, you must enable Server Name Indication (SNI) for the API routes.
A stateless load balancing algorithm. The options vary based on the load balancer implementation.

注意

Session persistence is not required for the API load balancer to function properly.

Configure the following ports on both the front and back of the load balancers:

表 4.31. API load balancer
Port	Back-end machines (pool members)	Internal	External	Description
`6443`	Bootstrap and control plane. You remove the bootstrap machine from the load balancer after the bootstrap machine initializes the cluster control plane. You must configure the `/readyz` endpoint for the API server health check probe.	X	X	Kubernetes API server
`22623`	Bootstrap and control plane. You remove the bootstrap machine from the load balancer after the bootstrap machine initializes the cluster control plane.	X		Machine config server

注意

Application Ingress load balancer: Provides an Ingress point for application traffic flowing in from outside the cluster. Configure the following conditions:

Layer 4 load balancing only. This can be referred to as Raw TCP, SSL Passthrough, or SSL Bridge mode. If you use SSL Bridge mode, you must enable Server Name Indication (SNI) for the Ingress routes.
A connection-based or session-based persistence is recommended, based on the options available and types of applications that will be hosted on the platform.

Configure the following ports on both the front and back of the load balancers:

表 4.32. Application Ingress load balancer
Port	Back-end machines (pool members)	Internal	External	Description
`443`	The machines that run the Ingress router pods, compute, or worker, by default.	X	X	HTTPS traffic
`80`	The machines that run the Ingress router pods, compute, or worker, by default.	X	X	HTTP traffic

提示

If the true IP address of the client can be seen by the load balancer, enabling source IP-based session persistence can improve performance for applications that use end-to-end TLS encryption.

注意

A working configuration for the Ingress router is required for an OpenShift Container Platform cluster. You must configure the Ingress router after the control plane initializes.

NTP configuration

If a DHCP server provides NTP server information, the chrony time service on the Red Hat Enterprise Linux CoreOS (RHCOS) machines read the information and can sync the clock with the NTP servers.

4.9.8. Creating load balancers in GCP

You must configure load balancers in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. One way to create these components is to modify the provided Deployment Manager template.

注意

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for the internal load balancer section of this topic and save it as 02_lb_int.py on your computer. This template describes the internal load balancing objects that your cluster requires.
For an external cluster, also copy the template from the Deployment Manager template for the external load balancer section of this topic and save it as 02_lb_ext.py on your computer. This template describes the external load balancing objects that your cluster requires.

4.9.9. Creating a private DNS zone in GCP

You must configure a private DNS zone in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. One way to create this component is to modify the provided Deployment Manager template.

注意

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for the private DNS section of this topic and save it as 02_dns.py on your computer. This template describes the private DNS objects that your cluster requires.

Create a 02_dns.yaml resource definition file:

Copy to Clipboard Toggle word wrap

cat <<EOF >02_dns.yaml
imports:
- path: 02_dns.py

resources:
- name: cluster-dns
  type: 02_dns.py
  properties:
    infra_id: '${INFRA_ID}'
    cluster_domain: '${CLUSTER_NAME}.${BASE_DOMAIN}'
    cluster_network: '${CLUSTER_NETWORK}'
EOF

$ cat <<EOF >02_dns.yaml
imports:
- path: 02_dns.py

resources:
- name: cluster-dns
  type: 02_dns.py
  properties:
    infra_id: '${INFRA_ID}'


    cluster_domain: '${CLUSTER_NAME}.${BASE_DOMAIN}'


    cluster_network: '${CLUSTER_NETWORK}'

EOF

1: infra_id is the INFRA_ID infrastructure name from the extraction step.
2: cluster_domain is the domain for the cluster, for example openshift.example.com.
3: cluster_network is the selfLink URL to the cluster network.

Create the deployment by using the gcloud CLI:

Copy to Clipboard Toggle word wrap

gcloud deployment-manager deployments create ${INFRA_ID}-dns --config 02_dns.yaml

$ gcloud deployment-manager deployments create ${INFRA_ID}-dns --config 02_dns.yaml

The templates do not create DNS entries due to limitations of Deployment Manager, so you must create them manually:

Add the internal DNS entries:

Copy to Clipboard Toggle word wrap

if [ -f transaction.yaml ]; then rm transaction.yaml; fi
gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone
gcloud dns record-sets transaction add ${CLUSTER_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone
gcloud dns record-sets transaction add ${CLUSTER_IP} --name api-int.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone
gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction add ${CLUSTER_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction add ${CLUSTER_IP} --name api-int.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone

For an external cluster, also add the external DNS entries:

Copy to Clipboard Toggle word wrap

if [ -f transaction.yaml ]; then rm transaction.yaml; fi
gcloud dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME}
gcloud dns record-sets transaction add ${CLUSTER_PUBLIC_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${BASE_DOMAIN_ZONE_NAME}
gcloud dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME}

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud dns record-sets transaction add ${CLUSTER_PUBLIC_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME}

4.9.9.1. Deployment Manager template for the private DNS

You can use the following Deployment Manager template to deploy the private DNS that you need for your OpenShift Container Platform cluster:

例 4.4. 02_dns.py Deployment Manager template

Copy to Clipboard Toggle word wrap

def GenerateConfig(context):

    resources = [{
        'name': context.properties['infra_id'] + '-private-zone',
        'type': 'dns.v1.managedZone',
        'properties': {
            'description': '',
            'dnsName': context.properties['cluster_domain'] + '.',
            'visibility': 'private',
            'privateVisibilityConfig': {
                'networks': [{
                    'networkUrl': context.properties['cluster_network']
                }]
            }
        }
    }]

    return {'resources': resources}

def GenerateConfig(context):

    resources = [{
        'name': context.properties['infra_id'] + '-private-zone',
        'type': 'dns.v1.managedZone',
        'properties': {
            'description': '',
            'dnsName': context.properties['cluster_domain'] + '.',
            'visibility': 'private',
            'privateVisibilityConfig': {
                'networks': [{
                    'networkUrl': context.properties['cluster_network']
                }]
            }
        }
    }]

    return {'resources': resources}

4.9.10. Creating firewall rules in GCP

You must create firewall rules in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. One way to create these components is to modify the provided Deployment Manager template.

注意

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for firewall rules section of this topic and save it as 03_firewall.py on your computer. This template describes the security groups that your cluster requires.

Create a 03_firewall.yaml resource definition file:

Copy to Clipboard Toggle word wrap

cat <<EOF >03_firewall.yaml
imports:
- path: 03_firewall.py

resources:
- name: cluster-firewall
  type: 03_firewall.py
  properties:
    allowed_external_cidr: '0.0.0.0/0'
    infra_id: '${INFRA_ID}'
    cluster_network: '${CLUSTER_NETWORK}'
    network_cidr: '${NETWORK_CIDR}'
EOF

$ cat <<EOF >03_firewall.yaml
imports:
- path: 03_firewall.py

resources:
- name: cluster-firewall
  type: 03_firewall.py
  properties:
    allowed_external_cidr: '0.0.0.0/0'


    infra_id: '${INFRA_ID}'


    cluster_network: '${CLUSTER_NETWORK}'


    network_cidr: '${NETWORK_CIDR}'

EOF

1: allowed_external_cidr is the CIDR range that can access the cluster API and SSH to the bootstrap host. For an internal cluster, set this value to ${NETWORK_CIDR}.
2: infra_id is the INFRA_ID infrastructure name from the extraction step.
3: cluster_network is the selfLink URL to the cluster network.
4: network_cidr is the CIDR of the VPC network, for example 10.0.0.0/16.

Create the deployment by using the gcloud CLI:

Copy to Clipboard Toggle word wrap

gcloud deployment-manager deployments create ${INFRA_ID}-firewall --config 03_firewall.yaml

$ gcloud deployment-manager deployments create ${INFRA_ID}-firewall --config 03_firewall.yaml

4.9.11. Creating IAM roles in GCP

You must create IAM roles in Google Cloud Platform (GCP) for your OpenShift Container Platform cluster to use. One way to create these components is to modify the provided Deployment Manager template.

注意

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for IAM roles section of this topic and save it as 03_iam.py on your computer. This template describes the IAM roles that your cluster requires.

Create a 03_iam.yaml resource definition file:

Copy to Clipboard Toggle word wrap

cat <<EOF >03_iam.yaml
imports:
- path: 03_iam.py
resources:
- name: cluster-iam
  type: 03_iam.py
  properties:
    infra_id: '${INFRA_ID}'
EOF

$ cat <<EOF >03_iam.yaml
imports:
- path: 03_iam.py
resources:
- name: cluster-iam
  type: 03_iam.py
  properties:
    infra_id: '${INFRA_ID}'

EOF

1: infra_id is the INFRA_ID infrastructure name from the extraction step.

Create the deployment by using the gcloud CLI:

Copy to Clipboard Toggle word wrap

gcloud deployment-manager deployments create ${INFRA_ID}-iam --config 03_iam.yaml

$ gcloud deployment-manager deployments create ${INFRA_ID}-iam --config 03_iam.yaml

Export the variable for the master service account:

Copy to Clipboard Toggle word wrap

export MASTER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-m@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

$ export MASTER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-m@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

Export the variable for the worker service account:

Copy to Clipboard Toggle word wrap

export WORKER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-w@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

$ export WORKER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-w@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

Export the variable for the subnet that hosts the compute machines:

Copy to Clipboard Toggle word wrap

export COMPUTE_SUBNET=(`gcloud compute networks subnets describe ${INFRA_ID}-worker-subnet --region=${REGION} --format json | jq -r .selfLink`)

$ export COMPUTE_SUBNET=(`gcloud compute networks subnets describe ${INFRA_ID}-worker-subnet --region=${REGION} --format json | jq -r .selfLink`)

The templates do not create the policy bindings due to limitations of Deployment Manager, so you must create them manually:

Copy to Clipboard Toggle word wrap

gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.instanceAdmin"
gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.networkAdmin"
gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.securityAdmin"
gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/iam.serviceAccountUser"
gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/storage.admin"
gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/compute.viewer"
gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/storage.admin"

$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.instanceAdmin"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.networkAdmin"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.securityAdmin"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/iam.serviceAccountUser"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/storage.admin"

$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/compute.viewer"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/storage.admin"

Create a service account key and store it locally for later use:

Copy to Clipboard Toggle word wrap

gcloud iam service-accounts keys create service-account-key.json --iam-account=${MASTER_SERVICE_ACCOUNT}

$ gcloud iam service-accounts keys create service-account-key.json --iam-account=${MASTER_SERVICE_ACCOUNT}

4.9.11.1. Deployment Manager template for IAM roles

You can use the following Deployment Manager template to deploy the IAM roles that you need for your OpenShift Container Platform cluster:

例 4.6. 03_iam.py Deployment Manager template

Copy to Clipboard Toggle word wrap

def GenerateConfig(context):

    resources = [{
        'name': context.properties['infra_id'] + '-master-node-sa',
        'type': 'iam.v1.serviceAccount',
        'properties': {

        'type': 'iam.v1.serviceAccount',
        'properties': {
            'accountId': context.properties['infra_id'] + '-w',
            'displayName': context.properties['infra_id'] + '-worker-node'
        }
    }]

    return {'resources': resources}

def GenerateConfig(context):

    resources = [{
        'name': context.properties['infra_id'] + '-master-node-sa',
        'type': 'iam.v1.serviceAccount',
        'properties': {
            'accountId': context.properties['infra_id'] + '-m',
            'displayName': context.properties['infra_id'] + '-master-node'
        }
    }, {

        'type': 'iam.v1.serviceAccount',
        'properties': {
            'accountId': context.properties['infra_id'] + '-w',
            'displayName': context.properties['infra_id'] + '-worker-node'
        }
    }]

    return {'resources': resources}

4.9.12. Creating the RHCOS cluster image for the GCP infrastructure

You must use a valid Red Hat Enterprise Linux CoreOS (RHCOS) image for Google Cloud Platform (GCP) for your OpenShift Container Platform nodes.

Procedure

Obtain the RHCOS image from the RHCOS image mirror page.
重要
The RHCOS images might not change with every release of OpenShift Container Platform. You must download an image with the highest version that is less than or equal to the OpenShift Container Platform version that you install. Use the image version that matches your OpenShift Container Platform version if it is available.
The file name contains the OpenShift Container Platform version number in the format rhcos-<version>-<arch>-gcp.<arch>.tar.gz.
Create the Google storage bucket:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
gsutil mb gs://<bucket_name>
```
```
$ gsutil mb gs://<bucket_name>
```

Upload the RHCOS image to the Google storage bucket:

Copy to Clipboard Toggle word wrap

gsutil cp <downloaded_image_file_path>/rhcos-<version>-x86_64-gcp.x86_64.tar.gz  gs://<bucket_name>

$ gsutil cp <downloaded_image_file_path>/rhcos-<version>-x86_64-gcp.x86_64.tar.gz  gs://<bucket_name>

Export the uploaded RHCOS image location as a variable:

Copy to Clipboard Toggle word wrap

export IMAGE_SOURCE=`gs://<bucket_name>/rhcos-<version>-x86_64-gcp.x86_64.tar.gz`

$ export IMAGE_SOURCE=`gs://<bucket_name>/rhcos-<version>-x86_64-gcp.x86_64.tar.gz`

Create the cluster image:

Copy to Clipboard Toggle word wrap

gcloud compute images create "${INFRA_ID}-rhcos-image" \
    --source-uri="${IMAGE_SOURCE}"

$ gcloud compute images create "${INFRA_ID}-rhcos-image" \
    --source-uri="${IMAGE_SOURCE}"

4.9.13. Creating the bootstrap machine in GCP

You must create the bootstrap machine in Google Cloud Platform (GCP) to use during OpenShift Container Platform cluster initialization. One way to create this machine is to modify the provided Deployment Manager template.

注意

If you do not use the provided Deployment Manager template to create your bootstrap machine, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Ensure pyOpenSSL is installed.

Procedure

Copy the template from the Deployment Manager template for the bootstrap machine section of this topic and save it as 04_bootstrap.py on your computer. This template describes the bootstrap machine that your cluster requires.

Export the location of the Red Hat Enterprise Linux CoreOS (RHCOS) image that the installation program requires:

Copy to Clipboard Toggle word wrap

export CLUSTER_IMAGE=(`gcloud compute images describe ${INFRA_ID}-rhcos-image --format json | jq -r .selfLink`)

$ export CLUSTER_IMAGE=(`gcloud compute images describe ${INFRA_ID}-rhcos-image --format json | jq -r .selfLink`)

Create a bucket and upload the bootstrap.ign file:

Copy to Clipboard Toggle word wrap

gsutil mb gs://${INFRA_ID}-bootstrap-ignition
gsutil cp <installation_directory>/bootstrap.ign gs://${INFRA_ID}-bootstrap-ignition/

$ gsutil mb gs://${INFRA_ID}-bootstrap-ignition
$ gsutil cp <installation_directory>/bootstrap.ign gs://${INFRA_ID}-bootstrap-ignition/

Create a signed URL for the bootstrap instance to use to access the Ignition config. Export the URL from the output as a variable:

Copy to Clipboard Toggle word wrap

export BOOTSTRAP_IGN=`gsutil signurl -d 1h service-account-key.json gs://${INFRA_ID}-bootstrap-ignition/bootstrap.ign | grep "^gs:" | awk '{print $5}'`

$ export BOOTSTRAP_IGN=`gsutil signurl -d 1h service-account-key.json gs://${INFRA_ID}-bootstrap-ignition/bootstrap.ign | grep "^gs:" | awk '{print $5}'`

Create a 04_bootstrap.yaml resource definition file:

    control_subnet: '${CONTROL_SUBNET}'
    image: '${CLUSTER_IMAGE}'
    machine_type: 'n1-standard-4'
    root_volume_size: '128'

    bootstrap_ign: '${BOOTSTRAP_IGN}'
EOF

$ cat <<EOF >04_bootstrap.yaml
imports:

    region: '${REGION}'


    zone: '${ZONE_0}'



    cluster_network: '${CLUSTER_NETWORK}'


    control_subnet: '${CONTROL_SUBNET}'


    image: '${CLUSTER_IMAGE}'


    machine_type: 'n1-standard-4'


    root_volume_size: '128'



    bootstrap_ign: '${BOOTSTRAP_IGN}'

EOF

1: infra_id is the INFRA_ID infrastructure name from the extraction step.
2: region is the region to deploy the cluster into, for example us-central1.
3: zone is the zone to deploy the bootstrap instance into, for example us-central1-b.
4: cluster_network is the selfLink URL to the cluster network.
5: control_subnet is the selfLink URL to the control subnet.
6: image is the selfLink URL to the RHCOS image.
7: machine_type is the machine type of the instance, for example n1-standard-4.
8: root_volume_size is the boot disk size for the bootstrap machine.
9: bootstrap_ign is the URL output when creating a signed URL.

Create the deployment by using the gcloud CLI:

Copy to Clipboard Toggle word wrap

gcloud deployment-manager deployments create ${INFRA_ID}-bootstrap --config 04_bootstrap.yaml

$ gcloud deployment-manager deployments create ${INFRA_ID}-bootstrap --config 04_bootstrap.yaml

The templates do not manage load balancer membership due to limitations of Deployment Manager, so you must add the bootstrap machine manually.

Add the bootstrap instance to the internal load balancer instance group:

Copy to Clipboard Toggle word wrap

gcloud compute instance-groups unmanaged add-instances \
    ${INFRA_ID}-bootstrap-instance-group --zone=${ZONE_0} --instances=${INFRA_ID}-bootstrap

$ gcloud compute instance-groups unmanaged add-instances \
    ${INFRA_ID}-bootstrap-instance-group --zone=${ZONE_0} --instances=${INFRA_ID}-bootstrap

Add the bootstrap instance group to the internal load balancer backend service:

Copy to Clipboard Toggle word wrap

gcloud compute backend-services add-backend \
    ${INFRA_ID}-api-internal-backend-service --region=${REGION} --instance-group=${INFRA_ID}-bootstrap-instance-group --instance-group-zone=${ZONE_0}

$ gcloud compute backend-services add-backend \
    ${INFRA_ID}-api-internal-backend-service --region=${REGION} --instance-group=${INFRA_ID}-bootstrap-instance-group --instance-group-zone=${ZONE_0}

4.9.14. Creating the control plane machines in GCP

You must create the control plane machines in Google Cloud Platform (GCP) for your cluster to use. One way to create these machines is to modify the provided Deployment Manager template.

注意

If you do not use the provided Deployment Manager template to create your control plane machines, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Create the bootstrap machine.

Procedure

Copy the template from the Deployment Manager template for control plane machines section of this topic and save it as 05_control_plane.py on your computer. This template describes the control plane machines that your cluster requires.

Export the following variable required by the resource definition:

Copy to Clipboard Toggle word wrap

export MASTER_IGNITION=`cat <installation_directory>/master.ign`

$ export MASTER_IGNITION=`cat <installation_directory>/master.ign`

Create a 05_control_plane.yaml resource definition file:

    image: '${CLUSTER_IMAGE}'


    machine_type: 'n1-standard-4'


    root_volume_size: '128'
    service_account_email: '${MASTER_SERVICE_ACCOUNT}'



    ignition: '${MASTER_IGNITION}'

EOF

1: infra_id is the INFRA_ID infrastructure name from the extraction step.
2: zones are the zones to deploy the control plane instances into, for example us-central1-a, us-central1-b, and us-central1-c.
3: control_subnet is the selfLink URL to the control subnet.
4: image is the selfLink URL to the RHCOS image.
5: machine_type is the machine type of the instance, for example n1-standard-4.
6: service_account_email is the email address for the master service account that you created.
7: ignition is the contents of the master.ign file.

Create the deployment by using the gcloud CLI:

Copy to Clipboard Toggle word wrap

gcloud deployment-manager deployments create ${INFRA_ID}-control-plane --config 05_control_plane.yaml

$ gcloud deployment-manager deployments create ${INFRA_ID}-control-plane --config 05_control_plane.yaml

The templates do not manage load balancer membership due to limitations of Deployment Manager, so you must add the control plane machines manually.

Run the following commands to add the control plane machines to the appropriate instance groups:

Copy to Clipboard Toggle word wrap

gcloud compute instance-groups unmanaged add-instances ${INFRA_ID}-master-${ZONE_0}-instance-group --zone=${ZONE_0} --instances=${INFRA_ID}-m-0
gcloud compute instance-groups unmanaged add-instances ${INFRA_ID}-master-${ZONE_1}-instance-group --zone=${ZONE_1} --instances=${INFRA_ID}-m-1
gcloud compute instance-groups unmanaged add-instances ${INFRA_ID}-master-${ZONE_2}-instance-group --zone=${ZONE_2} --instances=${INFRA_ID}-m-2

$ gcloud compute instance-groups unmanaged add-instances ${INFRA_ID}-master-${ZONE_0}-instance-group --zone=${ZONE_0} --instances=${INFRA_ID}-m-0
$ gcloud compute instance-groups unmanaged add-instances ${INFRA_ID}-master-${ZONE_1}-instance-group --zone=${ZONE_1} --instances=${INFRA_ID}-m-1
$ gcloud compute instance-groups unmanaged add-instances ${INFRA_ID}-master-${ZONE_2}-instance-group --zone=${ZONE_2} --instances=${INFRA_ID}-m-2

For an external cluster, you must also run the following commands to add the control plane machines to the target pools:

Copy to Clipboard Toggle word wrap

gcloud compute target-pools add-instances ${INFRA_ID}-api-target-pool --instances-zone="${ZONE_0}" --instances=${INFRA_ID}-m-0

gcloud compute target-pools add-instances ${INFRA_ID}-api-target-pool --instances-zone="${ZONE_2}" --instances=${INFRA_ID}-m-2

$ gcloud compute target-pools add-instances ${INFRA_ID}-api-target-pool --instances-zone="${ZONE_0}" --instances=${INFRA_ID}-m-0
$ gcloud compute target-pools add-instances ${INFRA_ID}-api-target-pool --instances-zone="${ZONE_1}" --instances=${INFRA_ID}-m-1
$ gcloud compute target-pools add-instances ${INFRA_ID}-api-target-pool --instances-zone="${ZONE_2}" --instances=${INFRA_ID}-m-2

4.9.15. Wait for bootstrap completion and remove bootstrap resources in GCP

After you create all of the required infrastructure in Google Cloud Platform (GCP), wait for the bootstrap process to complete on the machines that you provisioned by using the Ignition config files that you generated with the installation program.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.

Procedure

Change to the directory that contains the installation program and run the following command:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install wait-for bootstrap-complete --dir=<installation_directory> \

4.9.16. Creating additional worker machines in GCP

You can create worker machines in Google Cloud Platform (GCP) for your cluster to use by launching individual instances discretely or by automated processes outside the cluster, such as auto scaling groups. You can also take advantage of the built-in cluster scaling mechanisms and the machine API in OpenShift Container Platform.

In this example, you manually launch one instance by using the Deployment Manager template. Additional instances can be launched by including additional resources of type 06_worker.py in the file.

注意

If you do not use the provided Deployment Manager template to create your worker machines, you must review the provided information and manually create the infrastructure. If your cluster does not initialize correctly, you might have to contact Red Hat support with your installation logs.

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.

Procedure

Copy the template from the Deployment Manager template for worker machines section of this topic and save it as 06_worker.py on your computer. This template describes the worker machines that your cluster requires.

Export the variables that the resource definition uses.

Export the subnet that hosts the compute machines:

Copy to Clipboard Toggle word wrap

export COMPUTE_SUBNET=(`gcloud compute networks subnets describe ${INFRA_ID}-worker-subnet --region=${REGION} --format json | jq -r .selfLink`)

$ export COMPUTE_SUBNET=(`gcloud compute networks subnets describe ${INFRA_ID}-worker-subnet --region=${REGION} --format json | jq -r .selfLink`)

Export the email address for your service account:

Copy to Clipboard Toggle word wrap

NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  63m  v1.18.3
master-1  Ready     master  63m  v1.18.3
master-2  Ready     master  64m  v1.18.3
worker-0  NotReady  worker  76s  v1.18.3
worker-1  NotReady  worker  70s  v1.18.3

NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  63m  v1.18.3

master-2  Ready     master  64m  v1.18.3
worker-0  NotReady  worker  76s  v1.18.3
worker-1  NotReady  worker  70s  v1.18.3

The output lists all of the machines that you created.

Review the pending CSRs and ensure that you see the client requests with the Pending or Approved status for each machine that you added to the cluster:

Copy to Clipboard Toggle word wrap

oc get csr

$ oc get csr

Example output

Copy to Clipboard Toggle word wrap

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-8b2br   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-8b2br   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

In this example, two machines are joining the cluster. You might see more approved CSRs in the list.

If the CSRs were not approved, after all of the pending CSRs for the machines you added are in Pending status, approve the CSRs for your cluster machines:
注意
Because the CSRs rotate automatically, approve your CSRs within an hour of adding the machines to the cluster. If you do not approve them within an hour, the certificates will rotate, and more than two certificates will be present for each node. You must approve all of these certificates. Once the client CSR is approved, the Kubelet creates a secondary CSR for the serving certificate, which requires manual approval. Then, subsequent serving certificate renewal requests are automatically approved by the machine-approver if the Kubelet requests a new certificate with identical parameters.
- To approve them individually, run the following command for each valid CSR:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm certificate approve <csr_name>
```
```
$ oc adm certificate approve <csr_name> 
```
  1
  1
  <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```
```
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```

Now that your client requests are approved, you must review the server requests for each machine that you added to the cluster:

Copy to Clipboard Toggle word wrap

oc get csr

$ oc get csr

Example output

Copy to Clipboard Toggle word wrap

NAME        AGE     REQUESTOR                                                                   CONDITION

...

If the remaining CSRs are not approved, and are in the Pending status, approve the CSRs for your cluster machines:
- To approve them individually, run the following command for each valid CSR:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm certificate approve <csr_name>
```
```
$ oc adm certificate approve <csr_name> 
```
  1
  1
  <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve
```
```
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve
```

After all client and server CSRs have been approved, the machines have the Ready status. Verify this by running the following command:

Copy to Clipboard Toggle word wrap

oc get nodes

$ oc get nodes

Example output

Copy to Clipboard Toggle word wrap

4.9.20. Optional: Adding the ingress DNS records

If you removed the DNS zone configuration when creating Kubernetes manifests and generating Ignition configs, you must manually create DNS records that point at the ingress load balancer. You can create either a wildcard *.apps.{baseDomain}. or specific records. You can use A, CNAME, and other records per your requirements.

Prerequisites

Configure a GCP account.
Remove the DNS Zone configuration when creating Kubernetes manifests and generating Ignition configs.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.
Create the worker machines.

Procedure

Wait for the Ingress router to create a load balancer and populate the EXTERNAL-IP field:

Copy to Clipboard Toggle word wrap

oc -n openshift-ingress get service router-default

$ oc -n openshift-ingress get service router-default

Example output

Copy to Clipboard Toggle word wrap

NAME             TYPE           CLUSTER-IP      EXTERNAL-IP      PORT(S)                      AGE
router-default   LoadBalancer   172.30.18.154   35.233.157.184   80:32288/TCP,443:31215/TCP   98

NAME             TYPE           CLUSTER-IP      EXTERNAL-IP      PORT(S)                      AGE
router-default   LoadBalancer   172.30.18.154   35.233.157.184   80:32288/TCP,443:31215/TCP   98

Add the A record to your zones:

To use A records:

Export the variable for the router IP address:

Copy to Clipboard Toggle word wrap

export ROUTER_IP=`oc -n openshift-ingress get service router-default --no-headers | awk '{print $4}'`

$ export ROUTER_IP=`oc -n openshift-ingress get service router-default --no-headers | awk '{print $4}'`

Add the A record to the private zones:

Copy to Clipboard Toggle word wrap

if [ -f transaction.yaml ]; then rm transaction.yaml; fi
gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone
gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${INFRA_ID}-private-zone
gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${INFRA_ID}-private-zone
$ gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone

For an external cluster, also add the A record to the public zones:

Copy to Clipboard Toggle word wrap

if [ -f transaction.yaml ]; then rm transaction.yaml; fi
gcloud dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME}
gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${BASE_DOMAIN_ZONE_NAME}
gcloud dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME}

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME}

To add explicit domains instead of using a wildcard, create entries for each of the cluster’s current routes:

Copy to Clipboard Toggle word wrap

oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

$ oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

4.9.21. Completing a GCP installation on user-provisioned infrastructure

After you start the OpenShift Container Platform installation on Google Cloud Platform (GCP) user-provisioned infrastructure, you can monitor the cluster events until the cluster is ready.

Prerequisites

Deploy the bootstrap machine for an OpenShift Container Platform cluster on user-provisioned GCP infrastructure.
Install the oc CLI and log in.

Procedure

Complete the cluster installation:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install --dir=<installation_directory> wait-for install-complete
```
```
$ ./openshift-install --dir=<installation_directory> wait-for install-complete

```
```
INFO Waiting up to 30m0s for the cluster to initialize...
```
1
For <installation_directory>, specify the path to the directory that you stored the installation files in.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.

Observe the running state of your cluster.

Run the following command to view the current cluster version and status:

Copy to Clipboard Toggle word wrap

oc get clusterversion

$ oc get clusterversion

Example output

Copy to Clipboard Toggle word wrap

When the current cluster version is AVAILABLE, the installation is complete.

4.9.22. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

4.10. Installing a cluster with shared VPC on user-provisioned infrastructure in GCP by using Deployment Manager templates

In OpenShift Container Platform version 4.5, you can install a cluster into a shared Virtual Private Cloud (VPC) on Google Cloud Platform (GCP) that uses infrastructure that you provide. In this context, a cluster installed into a shared VPC is a cluster that is configured to use a VPC from a project different from where the cluster is being deployed.

A shared VPC enables an organization to connect resources from multiple projects to a common VPC network. You can communicate within the organization securely and efficiently by using internal IPs from that network. For more information about shared VPC, see Shared VPC overview in the GCP documentation.

The steps for performing a user-provided infrastructure installation into a shared VPC are outlined here. Several Deployment Manager templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods.

重要

The steps for performing a user-provisioned infrastructure installation are provided as an example only. Installing a cluster with infrastructure you provide requires knowledge of the cloud provider and the installation process of OpenShift Container Platform. Several Deployment Manager templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods; the templates are just an example.

4.10.1. Prerequisites

Review details about the OpenShift Container Platform installation and update processes.
If you use a firewall and plan to use telemetry, you must configure the firewall to allow the sites that your cluster requires access to.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.
注意
Be sure to also review this site list if you are configuring a proxy.

4.10.2. Certificate signing requests management

4.10.3. Configuring the GCP project that hosts your cluster

Before you can install OpenShift Container Platform, you must configure a Google Cloud Platform (GCP) project to host it.

4.10.3.1. Creating a GCP project

To install OpenShift Container Platform, you must create a project in your Google Cloud Platform (GCP) account to host the cluster.

Procedure

Create a project to host your OpenShift Container Platform cluster. See Creating and Managing Projects in the GCP documentation.
重要
Your GCP project must use the Premium Network Service Tier if you are using installer-provisioned infrastructure. The Standard Network Service Tier is not supported for clusters installed using the installation program. The installation program configures internal load balancing for the api-int.<cluster_name>.<base_domain> URL; the Premium Tier is required for internal load balancing.

4.10.3.2. Enabling API services in GCP

Your Google Cloud Platform (GCP) project requires access to several API services to complete OpenShift Container Platform installation.

Prerequisites

You created a project to host your cluster.

Procedure

Enable the following required API services in the project that hosts your cluster. See Enabling services in the GCP documentation.

表 4.33. Required API services
API service	Console service name
Cloud Deployment Manager V2 API	`deploymentmanager.googleapis.com`
Compute Engine API	`compute.googleapis.com`
Google Cloud APIs	`cloudapis.googleapis.com`

注意

If any of the quotas are insufficient during installation, the installation program displays an error that states both which quota was exceeded and the region.

If you plan to deploy your cluster in one of the following regions, you will exceed the maximum storage quota and are likely to exceed the CPU quota limit:

asia-east2
asia-northeast2
asia-south1
australia-southeast1
europe-north1
europe-west2
europe-west3
europe-west6
northamerica-northeast1
southamerica-east1
us-west2

4.10.3.4. Creating a service account in GCP

Prerequisites

You created a project to host your cluster.

Procedure

Create a service account in the project that you use to host your OpenShift Container Platform cluster. See Creating a service account in the GCP documentation.
Grant the service account the appropriate permissions. You can either grant the individual permissions that follow or assign the Owner role to it. See Granting roles to a service account for specific resources.
注意
While making the service account an owner of the project is the easiest way to gain the required permissions, it means that service account has complete control over the project. You must determine if the risk that comes from offering that power is acceptable.
Create the service account key in JSON format. See Creating service account keys in the GCP documentation.
The service account key is required to create a cluster.

4.10.3.4.1. Required GCP permissions

Required roles for the installation program

Compute Admin
Security Admin
Service Account Admin
Service Account User
Storage Admin

Required roles for creating network resources during installation

DNS Administrator

Required roles for user-provisioned GCP infrastructure

Deployment Manager Editor
Service Account Key Admin

Optional roles

For the cluster to create new limited credentials for its Operators, add the following role:

Service Account Key Admin

The roles are applied to the service accounts that the control plane and compute machines use:

表 4.35. GCP service account permissions

	`roles/storage.admin`
	`roles/iam.serviceAccountUser`
Compute	`roles/compute.viewer`
Compute	`roles/storage.admin`

4.10.3.5. Supported GCP regions

You can deploy an OpenShift Container Platform cluster to the following Google Cloud Platform (GCP) regions:

asia-east1 (Changhua County, Taiwan)
asia-east2 (Hong Kong)
asia-northeast1 (Tokyo, Japan)
asia-northeast2 (Osaka, Japan)
asia-south1 (Mumbai, India)
asia-southeast1 (Jurong West, Singapore)
australia-southeast1 (Sydney, Australia)
europe-north1 (Hamina, Finland)
europe-west1 (St. Ghislain, Belgium)
europe-west2 (London, England, UK)
europe-west3 (Frankfurt, Germany)
europe-west4 (Eemshaven, Netherlands)
europe-west6 (Zürich, Switzerland)
northamerica-northeast1 (Montréal, Québec, Canada)
southamerica-east1 (São Paulo, Brazil)
us-central1 (Council Bluffs, Iowa, USA)
us-east1 (Moncks Corner, South Carolina, USA)
us-east4 (Ashburn, Northern Virginia, USA)
us-west1 (The Dalles, Oregon, USA)
us-west2 (Los Angeles, California, USA)

4.10.3.6. Installing and configuring CLI tools for GCP

To install OpenShift Container Platform on Google Cloud Platform (GCP) using user-provisioned infrastructure, you must install and configure the CLI tools for GCP.

Prerequisites

You created a project to host your cluster.
You created a service account and granted it the required permissions.

Procedure

Install the following binaries in $PATH:
- gcloud
- gsutil
See Install the latest Cloud SDK version in the GCP documentation.
Authenticate using the gcloud tool with your configured service account.
See Authorizing with a service account in the GCP documentation.

4.10.4. Configuring the GCP project that hosts your shared VPC network

If you use a shared Virtual Private Cloud (VPC) to host your OpenShift Container Platform cluster in Google Cloud Platform (GCP), you must configure the project that hosts it.

注意

If you already have a project that hosts the shared VPC network, review this section to ensure that the project meets all of the requirements to install an OpenShift Container Platform cluster.

Procedure

Create a project to host the shared VPC for your OpenShift Container Platform cluster. See Creating and Managing Projects in the GCP documentation.
Create a service account in the project that hosts your shared VPC. See Creating a service account in the GCP documentation.
Grant the service account the appropriate permissions. You can either grant the individual permissions that follow or assign the Owner role to it. See Granting roles to a service account for specific resources.
注意
While making the service account an owner of the project is the easiest way to gain the required permissions, it means that service account has complete control over the project. You must determine if the risk that comes from offering that power is acceptable.
The service account for the project that hosts the shared VPC network requires the following roles:
- Compute Network User
- Compute Security Admin
- Deployment Manager Editor
- DNS Administrator
- Security Admin
- Network Management Admin

4.10.4.1. Configuring DNS for GCP

To install OpenShift Container Platform, the Google Cloud Platform (GCP) account you use must have a dedicated public hosted zone in the project that hosts the shared VPC that you install the cluster into. This zone must be authoritative for the domain. The DNS service provides cluster DNS resolution and name lookup for external connections to the cluster.

Procedure

Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through GCP or another source.
注意
If you purchase a new domain, it can take time for the relevant DNS changes to propagate. For more information about purchasing domains through Google, see Google Domains.
Create a public hosted zone for your domain or subdomain in your GCP project. See Creating public zones in the GCP documentation.
Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.
Extract the new authoritative name servers from the hosted zone records. See Look up your Cloud DNS name servers in the GCP documentation.
You typically have four name servers.
Update the registrar records for the name servers that your domain uses. For example, if you registered your domain to Google Domains, see the following topic in the Google Domains Help: How to switch to custom name servers.
If you migrated your root domain to Google Cloud DNS, migrate your DNS records. See Migrating to Cloud DNS in the GCP documentation.
If you use a subdomain, follow your company’s procedures to add its delegation records to the parent domain. This process might include a request to your company’s IT department or the division that controls the root domain and DNS services for your company.

4.10.4.2. Creating a VPC in GCP

注意

Prerequisites

Configure a GCP account.

Procedure

Copy the template from the Deployment Manager template for the VPC section of this topic and save it as 01_vpc.py on your computer. This template describes the VPC that your cluster requires.

4.10.5. Creating the installation files for GCP

4.10.5.1. Manually creating the installation configuration file

For installations of OpenShift Container Platform that use user-provisioned infrastructure, you manually generate your installation configuration file.

Prerequisites

Obtain the OpenShift Container Platform installation program and the access token for your cluster.

Procedure

Create an installation directory to store your required installation assets in:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
mkdir <installation_directory>
```
```
$ mkdir <installation_directory>
```
重要
You must create a directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
Customize the following install-config.yaml file template and save it in the <installation_directory>.
注意
You must name this configuration file install-config.yaml.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the next step of the installation process. You must back it up now.

4.10.5.2. Sample customized `install-config.yaml` file for GCP

You can customize the install-config.yaml file to specify more details about your OpenShift Container Platform cluster’s platform or modify the values of the required parameters.

重要

This sample YAML file is provided for reference only. You must obtain your install-config.yaml file by using the installation program and modify it.

publish: Internal

1: Specify the public DNS on the host project.
2 5: If you do not provide these parameters and values, the installation program provides the default value.
3 6: The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, -, and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used.
4: Whether to enable or disable simultaneous multithreading, or hyperthreading. By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled. If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines.
重要
If you disable simultaneous multithreading, ensure that your capacity planning accounts for the dramatically decreased machine performance. Use larger machine types, such as n1-standard-8, for your machines if you disable simultaneous multithreading.
7: Specify the main project where the VM instances reside.
8: Specify the region that your VPC network is in.
9: Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead.
10: You can optionally provide the sshKey value that you use to access the machines in your cluster.
注意
For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
11: How to publish the user-facing endpoints of your cluster. Set publish to Internal to deploy a private cluster, which cannot be accessed from the Internet. The default value is External. To use a shared VPC in a cluster that uses infrastructure that you provision, you must set publish to Internal. The installation program will no longer be able to access the public DNS zone for the base domain in the host project.

4.10.5.3. Configuring the cluster-wide proxy during installation

Prerequisites

An existing install-config.yaml file.
Review the sites that your cluster requires access to and determine whether any need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. Add sites to the Proxy object’s spec.noProxy field to bypass the proxy if necessary.
注意
The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr, networking.clusterNetwork[].cidr, and networking.serviceNetwork[] fields from your installation configuration.
For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint (169.254.169.254).

Procedure

Edit your install-config.yaml file and add the proxy settings. For example:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
  noProxy: example.com 
additionalTrustBundle: | 
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
```
apiVersion: v1
baseDomain: my.domain.com
proxy:
  httpProxy: http://<username>:<pswd>@<ip>:<port> 
```
1
```
  httpsProxy: http://<username>:<pswd>@<ip>:<port> 
```
2
```
  noProxy: example.com 
```
3
```
additionalTrustBundle: | 
```
4
```
    -----BEGIN CERTIFICATE-----
    <MY_TRUSTED_CA_CERT>
    -----END CERTIFICATE-----
...
```
1
A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpProxy value.
2
A proxy URL to use for creating HTTPS connections outside the cluster. If this field is not specified, then httpProxy is used for both HTTP and HTTPS connections. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must not specify an httpsProxy value.
3
A comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com, but not y.com. Use * to bypass proxy for all destinations.
4
If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the Proxy object’s trustedCA field. The additionalTrustBundle field is required unless the proxy’s identity certificate is signed by an authority from the RHCOS trust bundle. If you use an MITM transparent proxy network that does not require additional proxy configuration but requires additional CAs, you must provide the MITM CA certificate.
注意
The installation program does not support the proxy readinessEndpoints field.
Save the file and reference it when installing OpenShift Container Platform.

注意

Only the Proxy object named cluster is supported, and no additional proxies can be created.

4.10.5.4. Creating the Kubernetes manifest and Ignition config files

重要

Prerequisites

Obtain the OpenShift Container Platform installation program.
Create the install-config.yaml installation configuration file.

Procedure

Generate the Kubernetes manifests for the cluster:

Because you create and manage the worker machines yourself, you do not need to initialize these machines.
Modify the <installation_directory>/manifests/cluster-scheduler-02-config.yml Kubernetes manifest file to prevent pods from being scheduled on the control plane machines:
1. Open the <installation_directory>/manifests/cluster-scheduler-02-config.yml file.
2. Locate the mastersSchedulable parameter and set its value to False.
3. Save and exit the file.

Remove the privateZone sections from the <installation_directory>/manifests/cluster-dns-02-config.yml DNS configuration file:

1: Remove this section completely.

Configure the cloud provider for your VPC.

Open the <installation_directory>/manifests/cloud-provider-config.yaml file.
Add the network-project-id parameter and set its value to the ID of project that hosts the shared VPC network.
Add the network-name parameter and set its value to the name of the shared VPC network that hosts the OpenShift Container Platform cluster.
Replace the value of the subnetwork-name parameter with the value of the shared VPC subnet that hosts your compute machines.

The contents of the <installation_directory>/manifests/cloud-provider-config.yaml resemble the following example:

4.10.7. Networking requirements for user-provisioned infrastructure

All the Red Hat Enterprise Linux CoreOS (RHCOS) machines require network in initramfs during boot to fetch Ignition config from the machine config server.

You must configure the network connectivity between machines to allow cluster components to communicate. Each machine must be able to resolve the host names of all other machines in the cluster.

Protocol	Port	Description
ICMP	N/A	Network reachability tests
TCP	`1936`	Metrics
	`9000`-`9999`	Host level services, including the node exporter on ports `9100`-`9101` and the Cluster Version Operator on port `9099`.

Network topology requirements

The infrastructure that you provision for your cluster must meet the following network topology requirements.

重要

OpenShift Container Platform requires all nodes to have internet access to pull images for platform containers and provide telemetry data to Red Hat.

Load balancers

Before you install OpenShift Container Platform, you must provision two load balancers that meet the following requirements:

API load balancer: Provides a common endpoint for users, both human and machine, to interact with and configure the platform. Configure the following conditions:

Layer 4 load balancing only. This can be referred to as Raw TCP, SSL Passthrough, or SSL Bridge mode. If you use SSL Bridge mode, you must enable Server Name Indication (SNI) for the API routes.
A stateless load balancing algorithm. The options vary based on the load balancer implementation.

注意

Session persistence is not required for the API load balancer to function properly.

Configure the following ports on both the front and back of the load balancers:

表 4.39. API load balancer
Port	Back-end machines (pool members)	Internal	External	Description
`6443`	Bootstrap and control plane. You remove the bootstrap machine from the load balancer after the bootstrap machine initializes the cluster control plane. You must configure the `/readyz` endpoint for the API server health check probe.	X	X	Kubernetes API server
`22623`	Bootstrap and control plane. You remove the bootstrap machine from the load balancer after the bootstrap machine initializes the cluster control plane.	X		Machine config server

注意

Application Ingress load balancer: Provides an Ingress point for application traffic flowing in from outside the cluster. Configure the following conditions:

Layer 4 load balancing only. This can be referred to as Raw TCP, SSL Passthrough, or SSL Bridge mode. If you use SSL Bridge mode, you must enable Server Name Indication (SNI) for the Ingress routes.
A connection-based or session-based persistence is recommended, based on the options available and types of applications that will be hosted on the platform.

Configure the following ports on both the front and back of the load balancers:

表 4.40. Application Ingress load balancer
Port	Back-end machines (pool members)	Internal	External	Description
`443`	The machines that run the Ingress router pods, compute, or worker, by default.	X	X	HTTPS traffic
`80`	The machines that run the Ingress router pods, compute, or worker, by default.	X	X	HTTP traffic

提示

If the true IP address of the client can be seen by the load balancer, enabling source IP-based session persistence can improve performance for applications that use end-to-end TLS encryption.

注意

A working configuration for the Ingress router is required for an OpenShift Container Platform cluster. You must configure the Ingress router after the control plane initializes.

NTP configuration

If a DHCP server provides NTP server information, the chrony time service on the Red Hat Enterprise Linux CoreOS (RHCOS) machines read the information and can sync the clock with the NTP servers.

4.10.8. Creating load balancers in GCP

注意

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for the internal load balancer section of this topic and save it as 02_lb_int.py on your computer. This template describes the internal load balancing objects that your cluster requires.
For an external cluster, also copy the template from the Deployment Manager template for the external load balancer section of this topic and save it as 02_lb_ext.py on your computer. This template describes the external load balancing objects that your cluster requires.

Export the variables that the deployment template uses:

4.10.9. Creating a private DNS zone in GCP

注意

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for the private DNS section of this topic and save it as 02_dns.py on your computer. This template describes the private DNS objects that your cluster requires.

Create a 02_dns.yaml resource definition file:

Copy to Clipboard Toggle word wrap

cat <<EOF >02_dns.yaml
imports:
- path: 02_dns.py

resources:
- name: cluster-dns
  type: 02_dns.py
  properties:
    infra_id: '${INFRA_ID}'
    cluster_domain: '${CLUSTER_NAME}.${BASE_DOMAIN}'
    cluster_network: '${CLUSTER_NETWORK}'
EOF

$ cat <<EOF >02_dns.yaml
imports:
- path: 02_dns.py

resources:
- name: cluster-dns
  type: 02_dns.py
  properties:
    infra_id: '${INFRA_ID}'


    cluster_domain: '${CLUSTER_NAME}.${BASE_DOMAIN}'


    cluster_network: '${CLUSTER_NETWORK}'

EOF

1: infra_id is the INFRA_ID infrastructure name from the extraction step.
2: cluster_domain is the domain for the cluster, for example openshift.example.com.
3: cluster_network is the selfLink URL to the cluster network.

Create the deployment by using the gcloud CLI:

Copy to Clipboard Toggle word wrap

gcloud deployment-manager deployments create ${INFRA_ID}-dns --config 02_dns.yaml --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

$ gcloud deployment-manager deployments create ${INFRA_ID}-dns --config 02_dns.yaml --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

The templates do not create DNS entries due to limitations of Deployment Manager, so you must create them manually:

Add the internal DNS entries:

Copy to Clipboard Toggle word wrap

if [ -f transaction.yaml ]; then rm transaction.yaml; fi
gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
gcloud dns record-sets transaction add ${CLUSTER_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
gcloud dns record-sets transaction add ${CLUSTER_IP} --name api-int.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
$ gcloud dns record-sets transaction add ${CLUSTER_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
$ gcloud dns record-sets transaction add ${CLUSTER_IP} --name api-int.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
$ gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

For an external cluster, also add the external DNS entries:

Copy to Clipboard Toggle word wrap

if [ -f transaction.yaml ]; then rm transaction.yaml; fi
gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME}
gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} dns record-sets transaction add ${CLUSTER_PUBLIC_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${BASE_DOMAIN_ZONE_NAME}
gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME}

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} dns record-sets transaction add ${CLUSTER_PUBLIC_IP} --name api.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 60 --type A --zone ${BASE_DOMAIN_ZONE_NAME}
$ gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME}

4.10.9.1. Deployment Manager template for the private DNS

You can use the following Deployment Manager template to deploy the private DNS that you need for your OpenShift Container Platform cluster:

例 4.13. 02_dns.py Deployment Manager template

Copy to Clipboard Toggle word wrap

def GenerateConfig(context):

    resources = [{
        'name': context.properties['infra_id'] + '-private-zone',
        'type': 'dns.v1.managedZone',
        'properties': {
            'description': '',
            'dnsName': context.properties['cluster_domain'] + '.',
            'visibility': 'private',
            'privateVisibilityConfig': {
                'networks': [{
                    'networkUrl': context.properties['cluster_network']
                }]
            }
        }
    }]

    return {'resources': resources}

def GenerateConfig(context):

    resources = [{
        'name': context.properties['infra_id'] + '-private-zone',
        'type': 'dns.v1.managedZone',
        'properties': {
            'description': '',
            'dnsName': context.properties['cluster_domain'] + '.',
            'visibility': 'private',
            'privateVisibilityConfig': {
                'networks': [{
                    'networkUrl': context.properties['cluster_network']
                }]
            }
        }
    }]

    return {'resources': resources}

4.10.10. Creating firewall rules in GCP

注意

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for firewall rules section of this topic and save it as 03_firewall.py on your computer. This template describes the security groups that your cluster requires.

Create a 03_firewall.yaml resource definition file:

Copy to Clipboard Toggle word wrap

cat <<EOF >03_firewall.yaml
imports:
- path: 03_firewall.py

resources:
- name: cluster-firewall
  type: 03_firewall.py
  properties:
    allowed_external_cidr: '0.0.0.0/0'
    infra_id: '${INFRA_ID}'
    cluster_network: '${CLUSTER_NETWORK}'
    network_cidr: '${NETWORK_CIDR}'
EOF

$ cat <<EOF >03_firewall.yaml
imports:
- path: 03_firewall.py

resources:
- name: cluster-firewall
  type: 03_firewall.py
  properties:
    allowed_external_cidr: '0.0.0.0/0'


    infra_id: '${INFRA_ID}'


    cluster_network: '${CLUSTER_NETWORK}'


    network_cidr: '${NETWORK_CIDR}'

EOF

1: allowed_external_cidr is the CIDR range that can access the cluster API and SSH to the bootstrap host. For an internal cluster, set this value to ${NETWORK_CIDR}.
2: infra_id is the INFRA_ID infrastructure name from the extraction step.
3: cluster_network is the selfLink URL to the cluster network.
4: network_cidr is the CIDR of the VPC network, for example 10.0.0.0/16.

Create the deployment by using the gcloud CLI:

Copy to Clipboard Toggle word wrap

gcloud deployment-manager deployments create ${INFRA_ID}-firewall --config 03_firewall.yaml --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

$ gcloud deployment-manager deployments create ${INFRA_ID}-firewall --config 03_firewall.yaml --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

4.10.11. Creating IAM roles in GCP

注意

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.
Create and configure a VPC and associated subnets in GCP.

Procedure

Copy the template from the Deployment Manager template for IAM roles section of this topic and save it as 03_iam.py on your computer. This template describes the IAM roles that your cluster requires.

Create a 03_iam.yaml resource definition file:

Copy to Clipboard Toggle word wrap

cat <<EOF >03_iam.yaml
imports:
- path: 03_iam.py
resources:
- name: cluster-iam
  type: 03_iam.py
  properties:
    infra_id: '${INFRA_ID}'
EOF

$ cat <<EOF >03_iam.yaml
imports:
- path: 03_iam.py
resources:
- name: cluster-iam
  type: 03_iam.py
  properties:
    infra_id: '${INFRA_ID}'

EOF

1: infra_id is the INFRA_ID infrastructure name from the extraction step.

Create the deployment by using the gcloud CLI:

Copy to Clipboard Toggle word wrap

gcloud deployment-manager deployments create ${INFRA_ID}-iam --config 03_iam.yaml

$ gcloud deployment-manager deployments create ${INFRA_ID}-iam --config 03_iam.yaml

Export the variable for the master service account:

Copy to Clipboard Toggle word wrap

export MASTER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-m@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

$ export MASTER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-m@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

Export the variable for the worker service account:

Copy to Clipboard Toggle word wrap

export WORKER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-w@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

$ export WORKER_SERVICE_ACCOUNT=(`gcloud iam service-accounts list --filter "email~^${INFRA_ID}-w@${PROJECT_NAME}." --format json | jq -r '.[0].email'`)

Assign the permissions that the installation program requires to the service accounts for the subnets that host the control plane and compute subnets:

Grant the networkViewer role of the project that hosts your shared VPC to the master service account:

Copy to Clipboard Toggle word wrap

gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} projects add-iam-policy-binding ${HOST_PROJECT} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.networkViewer"

$ gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} projects add-iam-policy-binding ${HOST_PROJECT} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.networkViewer"

Grant the networkUser role to the master service account for the control plane subnet:

Copy to Clipboard Toggle word wrap

gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} compute networks subnets add-iam-policy-binding "${HOST_PROJECT_CONTROL_SUBNET}" --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.networkUser" --region ${REGION}

Grant the networkUser role to the master service account for the compute subnet:

Copy to Clipboard Toggle word wrap

gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} compute networks subnets add-iam-policy-binding "${HOST_PROJECT_COMPUTE_SUBNET}" --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.networkUser" --region ${REGION}

$ gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} compute networks subnets add-iam-policy-binding "${HOST_PROJECT_COMPUTE_SUBNET}" --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.networkUser" --region ${REGION}

Grant the networkUser role to the worker service account for the compute subnet:

Copy to Clipboard Toggle word wrap

gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} compute networks subnets add-iam-policy-binding "${HOST_PROJECT_COMPUTE_SUBNET}" --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/compute.networkUser" --region ${REGION}

$ gcloud --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT} compute networks subnets add-iam-policy-binding "${HOST_PROJECT_COMPUTE_SUBNET}" --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/compute.networkUser" --region ${REGION}

The templates do not create the policy bindings due to limitations of Deployment Manager, so you must create them manually:

Copy to Clipboard Toggle word wrap

gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${MASTER_SERVICE_ACCOUNT}" --role "roles/compute.instanceAdmin"

$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/compute.viewer"
$ gcloud projects add-iam-policy-binding ${PROJECT_NAME} --member "serviceAccount:${WORKER_SERVICE_ACCOUNT}" --role "roles/storage.admin"

Create a service account key and store it locally for later use:

4.10.12. Creating the RHCOS cluster image for the GCP infrastructure

You must use a valid Red Hat Enterprise Linux CoreOS (RHCOS) image for Google Cloud Platform (GCP) for your OpenShift Container Platform nodes.

Procedure

Obtain the RHCOS image from the RHCOS image mirror page.
重要
The RHCOS images might not change with every release of OpenShift Container Platform. You must download an image with the highest version that is less than or equal to the OpenShift Container Platform version that you install. Use the image version that matches your OpenShift Container Platform version if it is available.
The file name contains the OpenShift Container Platform version number in the format rhcos-<version>-<arch>-gcp.<arch>.tar.gz.
Create the Google storage bucket:

1: infra_id is the INFRA_ID infrastructure name from the extraction step.
2: zones are the zones to deploy the control plane instances into, for example us-central1-a, us-central1-b, and us-central1-c.
3: control_subnet is the selfLink URL to the control subnet.
4: image is the selfLink URL to the RHCOS image.
5: machine_type is the machine type of the instance, for example n1-standard-4.
6: service_account_email is the email address for the master service account that you created.
7: ignition is the contents of the master.ign file.

Create the deployment by using the gcloud CLI:

Copy to Clipboard Toggle word wrap

gcloud deployment-manager deployments create ${INFRA_ID}-control-plane --config 05_control_plane.yaml

$ gcloud deployment-manager deployments create ${INFRA_ID}-control-plane --config 05_control_plane.yaml

The templates do not manage load balancer membership due to limitations of Deployment Manager, so you must add the control plane machines manually.

Run the following commands to add the control plane machines to the appropriate instance groups:

$ oc get nodes

Example output

Copy to Clipboard Toggle word wrap

NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  63m  v1.18.3
master-1  Ready     master  63m  v1.18.3
master-2  Ready     master  64m  v1.18.3
worker-0  NotReady  worker  76s  v1.18.3
worker-1  NotReady  worker  70s  v1.18.3

NAME      STATUS    ROLES   AGE  VERSION
master-0  Ready     master  63m  v1.18.3

master-2  Ready     master  64m  v1.18.3
worker-0  NotReady  worker  76s  v1.18.3
worker-1  NotReady  worker  70s  v1.18.3

The output lists all of the machines that you created.

Review the pending CSRs and ensure that you see the client requests with the Pending or Approved status for each machine that you added to the cluster:

Copy to Clipboard Toggle word wrap

oc get csr

$ oc get csr

Example output

Copy to Clipboard Toggle word wrap

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-8b2br   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

NAME        AGE     REQUESTOR                                                                   CONDITION
csr-8b2br   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
csr-8vnps   15m     system:serviceaccount:openshift-machine-config-operator:node-bootstrapper   Pending
...

In this example, two machines are joining the cluster. You might see more approved CSRs in the list.

If the CSRs were not approved, after all of the pending CSRs for the machines you added are in Pending status, approve the CSRs for your cluster machines:
注意
Because the CSRs rotate automatically, approve your CSRs within an hour of adding the machines to the cluster. If you do not approve them within an hour, the certificates will rotate, and more than two certificates will be present for each node. You must approve all of these certificates. Once the client CSR is approved, the Kubelet creates a secondary CSR for the serving certificate, which requires manual approval. Then, subsequent serving certificate renewal requests are automatically approved by the machine-approver if the Kubelet requests a new certificate with identical parameters.
- To approve them individually, run the following command for each valid CSR:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm certificate approve <csr_name>
```
```
$ oc adm certificate approve <csr_name> 
```
  1
  1
  <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```
```
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve
```

Now that your client requests are approved, you must review the server requests for each machine that you added to the cluster:

Copy to Clipboard Toggle word wrap

oc get csr

$ oc get csr

Example output

Copy to Clipboard Toggle word wrap

NAME        AGE     REQUESTOR                                                                   CONDITION

...

If the remaining CSRs are not approved, and are in the Pending status, approve the CSRs for your cluster machines:
- To approve them individually, run the following command for each valid CSR:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc adm certificate approve <csr_name>
```
```
$ oc adm certificate approve <csr_name> 
```
  1
  1
  <csr_name> is the name of a CSR from the list of current CSRs.
- To approve all pending CSRs, run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve
```
```
$ oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs oc adm certificate approve
```

After all client and server CSRs have been approved, the machines have the Ready status. Verify this by running the following command:

Copy to Clipboard Toggle word wrap

oc get nodes

$ oc get nodes

Example output

4.10.20. Adding the ingress DNS records

DNS zone configuration is removed when creating Kubernetes manifests and generating Ignition configs. You must manually create DNS records that point at the ingress load balancer. You can create either a wildcard *.apps.{baseDomain}. or specific records. You can use A, CNAME, and other records per your requirements.

Prerequisites

Configure a GCP account.
Remove the DNS Zone configuration when creating Kubernetes manifests and generating Ignition configs.
Create and configure a VPC and associated subnets in GCP.
Create and configure networking and load balancers in GCP.
Create control plane and compute roles.
Create the bootstrap machine.
Create the control plane machines.
Create the worker machines.

Procedure

Wait for the Ingress router to create a load balancer and populate the EXTERNAL-IP field:

Copy to Clipboard Toggle word wrap

oc -n openshift-ingress get service router-default

$ oc -n openshift-ingress get service router-default

Example output

Copy to Clipboard Toggle word wrap

NAME             TYPE           CLUSTER-IP      EXTERNAL-IP      PORT(S)                      AGE
router-default   LoadBalancer   172.30.18.154   35.233.157.184   80:32288/TCP,443:31215/TCP   98

NAME             TYPE           CLUSTER-IP      EXTERNAL-IP      PORT(S)                      AGE
router-default   LoadBalancer   172.30.18.154   35.233.157.184   80:32288/TCP,443:31215/TCP   98

Add the A record to your zones:

To use A records:

Export the variable for the router IP address:

Copy to Clipboard Toggle word wrap

export ROUTER_IP=`oc -n openshift-ingress get service router-default --no-headers | awk '{print $4}'`

$ export ROUTER_IP=`oc -n openshift-ingress get service router-default --no-headers | awk '{print $4}'`

Add the A record to the private zones:

Copy to Clipboard Toggle word wrap

if [ -f transaction.yaml ]; then rm transaction.yaml; fi
gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
$ gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
$ gcloud dns record-sets transaction execute --zone ${INFRA_ID}-private-zone --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

For an external cluster, also add the A record to the public zones:

Copy to Clipboard Toggle word wrap

if [ -f transaction.yaml ]; then rm transaction.yaml; fi
gcloud dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME} --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${BASE_DOMAIN_ZONE_NAME} --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
gcloud dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME} --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

$ if [ -f transaction.yaml ]; then rm transaction.yaml; fi
$ gcloud dns record-sets transaction start --zone ${BASE_DOMAIN_ZONE_NAME} --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
$ gcloud dns record-sets transaction add ${ROUTER_IP} --name \*.apps.${CLUSTER_NAME}.${BASE_DOMAIN}. --ttl 300 --type A --zone ${BASE_DOMAIN_ZONE_NAME} --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}
$ gcloud dns record-sets transaction execute --zone ${BASE_DOMAIN_ZONE_NAME} --project ${HOST_PROJECT} --account ${HOST_PROJECT_ACCOUNT}

To add explicit domains instead of using a wildcard, create entries for each of the cluster’s current routes:

Copy to Clipboard Toggle word wrap

oc get --all-namespaces -o jsonpath='{range .items[*]}{range .status.ingress[*]}{.host}{"\n"}{end}{end}' routes

4.10.21. Adding ingress firewall rules

The cluster requires several firewall rules. If you do not use a shared VPC, these rules are created by the ingress controller via the GCP cloud provider. When you use a shared VPC, you can either create cluster-wide firewall rules for all services now or create each rule based on events, when the cluster requests access. By creating each rule when the cluster requests access, you know exactly which firewall rules are required. By creating cluster-wide firewall rules, you can apply the same rule set across multiple clusters.

If you choose to create each rule based on events, you must create firewall rules after you provision the cluster and during the life of the cluster when the console notifies you that rules are missing. Events that are similar to the following event are displayed, and you must add the firewall rules that are required:

Copy to Clipboard Toggle word wrap

oc get events -n openshift-ingress --field-selector="reason=LoadBalancerManualChange"

$ oc get events -n openshift-ingress --field-selector="reason=LoadBalancerManualChange"

Firewall change required by security admin: `gcloud compute firewall-rules create k8s-fw-a26e631036a3f46cba28f8df67266d55 --network example-network --description "{\"kubernetes.io/service-name\":\"openshift-ingress/router-default\", \"kubernetes.io/service-ip\":\"35.237.236.234\"}\" --allow tcp:443,tcp:80 --source-ranges 0.0.0.0/0 --target-tags exampl-fqzq7-master,exampl-fqzq7-worker --project example-project`

If you encounter issues when creating these rule-based events, you can configure the cluster-wide firewall rules while your cluster is running.

4.10.21.1. Creating cluster-wide firewall rules for a shared VPC in GCP

You can create cluster-wide firewall rules to allow the access that the OpenShift Container Platform cluster requires.

警告

If you do not choose to create firewall rules based on cluster events, you must create cluster-wide firewall rules.

Prerequisites

You exported the variables that the Deployment Manager templates require to deploy your cluster.
You created the networking and load balancing components in GCP that your cluster requires.

Procedure

Add a single firewall rule to allow the Google Cloud Engine health checks to access all of the services. This rule enables the ingress load balancers to determine the health status of their instances.

Copy to Clipboard Toggle word wrap

gcloud compute firewall-rules create --allow='tcp:30000-32767,udp:30000-32767' --network="${CLUSTER_NETWORK}" --source-ranges='130.211.0.0/22,35.191.0.0/16,209.85.152.0/22,209.85.204.0/22' --target-tags="${INFRA_ID}-master,${INFRA_ID}-worker" ${INFRA_ID}-ingress-hc --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT}

$ gcloud compute firewall-rules create --allow='tcp:30000-32767,udp:30000-32767' --network="${CLUSTER_NETWORK}" --source-ranges='130.211.0.0/22,35.191.0.0/16,209.85.152.0/22,209.85.204.0/22' --target-tags="${INFRA_ID}-master,${INFRA_ID}-worker" ${INFRA_ID}-ingress-hc --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT}

Add a single firewall rule to allow access to all cluster services:

For an external cluster:

Copy to Clipboard Toggle word wrap

gcloud compute firewall-rules create --allow='tcp:80,tcp:443' --network="${CLUSTER_NETWORK}" --source-ranges="0.0.0.0/0" --target-tags="${INFRA_ID}-master,${INFRA_ID}-worker" ${INFRA_ID}-ingress --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT}

$ gcloud compute firewall-rules create --allow='tcp:80,tcp:443' --network="${CLUSTER_NETWORK}" --source-ranges="0.0.0.0/0" --target-tags="${INFRA_ID}-master,${INFRA_ID}-worker" ${INFRA_ID}-ingress --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT}

For a private cluster:

Copy to Clipboard Toggle word wrap

gcloud compute firewall-rules create --allow='tcp:80,tcp:443' --network="${CLUSTER_NETWORK}" --source-ranges=${NETWORK_CIDR} --target-tags="${INFRA_ID}-master,${INFRA_ID}-worker" ${INFRA_ID}-ingress --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT}

$ gcloud compute firewall-rules create --allow='tcp:80,tcp:443' --network="${CLUSTER_NETWORK}" --source-ranges=${NETWORK_CIDR} --target-tags="${INFRA_ID}-master,${INFRA_ID}-worker" ${INFRA_ID}-ingress --account=${HOST_PROJECT_ACCOUNT} --project=${HOST_PROJECT}

Because this rule only allows traffic on TCP ports 80 and 443, ensure that you add all the ports that your services use.

4.10.22. Completing a GCP installation on user-provisioned infrastructure

After you start the OpenShift Container Platform installation on Google Cloud Platform (GCP) user-provisioned infrastructure, you can monitor the cluster events until the cluster is ready.

Prerequisites

Deploy the bootstrap machine for an OpenShift Container Platform cluster on user-provisioned GCP infrastructure.
Install the oc CLI and log in.

Procedure

Complete the cluster installation:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install --dir=<installation_directory> wait-for install-complete
```
```
$ ./openshift-install --dir=<installation_directory> wait-for install-complete

For <installation_directory>, specify the path to the directory that you stored the installation files in.
重要
The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information.

Observe the running state of your cluster.

When the current cluster version is AVAILABLE, the installation is complete.

4.10.23. Next steps

Customize your cluster.
If necessary, you can opt out of remote health reporting.

4.11. Installing a cluster on GCP in a restricted network with user-provisioned infrastructure

In OpenShift Container Platform version 4.5, you can install a cluster on Google Cloud Platform (GCP) that uses infrastructure that you provide and an internal mirror of the installation release content.

重要

While you can install an OpenShift Container Platform cluster by using mirrored installation release content, your cluster still requires internet access to use the GCP APIs.

重要

The steps for performing a user-provisioned infrastructure installation are provided as an example only. Installing a cluster with infrastructure you provide requires knowledge of the cloud provider and the installation process of OpenShift Container Platform. Several Deployment Manager templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods; the templates are just an example.

4.11.1. Prerequisites

Create a registry on your mirror host and obtain the imageContentSources data for your version of OpenShift Container Platform.

Because the installation media is on the mirror host, you can use that computer to complete all installation steps.
Review details about the OpenShift Container Platform installation and update processes.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to. While you might need to grant access to more sites, you must grant access to *.googleapis.com and accounts.google.com.
If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.

4.11.2. Configuring your GCP project

Before you can install OpenShift Container Platform, you must configure a Google Cloud Platform (GCP) project to host it.

4.11.2.1. Creating a GCP project

To install OpenShift Container Platform, you must create a project in your Google Cloud Platform (GCP) account to host the cluster.

Procedure

Create a project to host your OpenShift Container Platform cluster. See Creating and Managing Projects in the GCP documentation.
重要
Your GCP project must use the Premium Network Service Tier if you are using installer-provisioned infrastructure. The Standard Network Service Tier is not supported for clusters installed using the installation program. The installation program configures internal load balancing for the api-int.<cluster_name>.<base_domain> URL; the Premium Tier is required for internal load balancing.

4.11.2.2. Enabling API services in GCP

Your Google Cloud Platform (GCP) project requires access to several API services to complete OpenShift Container Platform installation.

Prerequisites

You created a project to host your cluster.

Procedure

Enable the following required API services in the project that hosts your cluster. See Enabling services in the GCP documentation.

表 4.41. Required API services
API service	Console service name
Compute Engine API	`compute.googleapis.com`
Google Cloud APIs	`cloudapis.googleapis.com`
Cloud Resource Manager API	`cloudresourcemanager.googleapis.com`
Google DNS API	`dns.googleapis.com`
IAM Service Account Credentials API	`iamcredentials.googleapis.com`
Identity and Access Management (IAM) API	`iam.googleapis.com`
Service Management API	`servicemanagement.googleapis.com`
Service Usage API	`serviceusage.googleapis.com`
Google Cloud Storage JSON API	`storage-api.googleapis.com`
Cloud Storage	`storage-component.googleapis.com`

4.11.2.3. Configuring DNS for GCP

Procedure

Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through GCP or another source.
注意
If you purchase a new domain, it can take time for the relevant DNS changes to propagate. For more information about purchasing domains through Google, see Google Domains.
Create a public hosted zone for your domain or subdomain in your GCP project. See Creating public zones in the GCP documentation.
Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.
Extract the new authoritative name servers from the hosted zone records. See Look up your Cloud DNS name servers in the GCP documentation.
You typically have four name servers.
Update the registrar records for the name servers that your domain uses. For example, if you registered your domain to Google Domains, see the following topic in the Google Domains Help: How to switch to custom name servers.
If you migrated your root domain to Google Cloud DNS, migrate your DNS records. See Migrating to Cloud DNS in the GCP documentation.
If you use a subdomain, follow your company’s procedures to add its delegation records to the parent domain. This process might include a request to your company’s IT department or the division that controls the root domain and DNS services for your company.

4.11.2.4. GCP account limits

表 4.42. GCP resources used in a default cluster
Service	Component	Location	Total resources required	Resources removed after bootstrap
Service account	IAM	Global	5	0
Firewall rules	Networking	Global	11	1
Forwarding rules	Compute	Global	2	0
Health checks	Compute	Global	2	0
Images	Compute	Global	1	0
Networks	Networking	Global	1	0
Routers	Networking	Global	1	0
Routes	Networking	Global	2	0
Subnetworks	Compute	Global	2	0
Target pools	Networking	Global	2	0

注意

If any of the quotas are insufficient during installation, the installation program displays an error that states both which quota was exceeded and the region.

If you plan to deploy your cluster in one of the following regions, you will exceed the maximum storage quota and are likely to exceed the CPU quota limit:

asia-east2
asia-northeast2
asia-south1
australia-southeast1
europe-north1
europe-west2
europe-west3
europe-west6
northamerica-northeast1
southamerica-east1
us-west2

4.11.2.5. Creating a service account in GCP

Prerequisites

You created a project to host your cluster.

Procedure

Create a service account in the project that you use to host your OpenShift Container Platform cluster. See Creating a service account in the GCP documentation.
Grant the service account the appropriate permissions. You can either grant the individual permissions that follow or assign the Owner role to it. See Granting roles to a service account for specific resources.
注意
While making the service account an owner of the project is the easiest way to gain the required permissions, it means that service account has complete control over the project. You must determine if the risk that comes from offering that power is acceptable.
Create the service account key in JSON format. See Creating service account keys in the GCP documentation.
The service account key is required to create a cluster.

4.11.2.5.1. Required GCP permissions

Required roles for the installation program

Compute Admin
Security Admin
Service Account Admin
Service Account User
Storage Admin

Required roles for creating network resources during installation

DNS Administrator

Required roles for user-provisioned GCP infrastructure

Deployment Manager Editor
Service Account Key Admin

Optional roles

For the cluster to create new limited credentials for its Operators, add the following role:

Service Account Key Admin

The roles are applied to the service accounts that the control plane and compute machines use:

表 4.43. GCP service account permissions
Account	Roles
Control Plane	`roles/compute.instanceAdmin`
	`roles/compute.networkAdmin`
	`roles/compute.securityAdmin`
	`roles/storage.admin`
	`roles/iam.serviceAccountUser`
Compute	`roles/compute.viewer`
Compute	`roles/storage.admin`

4.11.2.6. Supported GCP regions

You can deploy an OpenShift Container Platform cluster to the following Google Cloud Platform (GCP) regions:

asia-east1 (Changhua County, Taiwan)
asia-east2 (Hong Kong)
asia-northeast1 (Tokyo, Japan)
asia-northeast2 (Osaka, Japan)
asia-south1 (Mumbai, India)
asia-southeast1 (Jurong West, Singapore)
australia-southeast1 (Sydney, Australia)
europe-north1 (Hamina, Finland)
europe-west1 (St. Ghislain, Belgium)
europe-west2 (London, England, UK)
europe-west3 (Frankfurt, Germany)
europe-west4 (Eemshaven, Netherlands)
europe-west6 (Zürich, Switzerland)
northamerica-northeast1 (Montréal, Québec, Canada)
southamerica-east1 (São Paulo, Brazil)

us-east1 (Moncks Corner, South Carolina, USA)
us-east4 (Ashburn, Northern Virginia, USA)
us-west1 (The Dalles, Oregon, USA)
us-west2 (Los Angeles, California, USA)

4.11.2.7. Installing and configuring CLI tools for GCP

To install OpenShift Container Platform on Google Cloud Platform (GCP) using user-provisioned infrastructure, you must install and configure the CLI tools for GCP.

Prerequisites

You created a project to host your cluster.
You created a service account and granted it the required permissions.

Procedure

Install the following binaries in $PATH:
- gcloud
- gsutil
See Install the latest Cloud SDK version in the GCP documentation.
Authenticate using the gcloud tool with your configured service account.
See Authorizing with a service account in the GCP documentation.

4.11.3. Creating the installation files for GCP

4.11.3.1. Creating the installation configuration file

You can customize the OpenShift Container Platform cluster you install on Google Cloud Platform (GCP).

Prerequisites

Obtain the OpenShift Container Platform installation program and the pull secret for your cluster.

Procedure

Create the install-config.yaml file.
1. Run the following command:
  Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
./openshift-install create install-config --dir=<installation_directory>
```
```
$ ./openshift-install create install-config --dir=<installation_directory> 
```
  1
  1
  For <installation_directory>, specify the directory name to store the files that the installation program creates.
  重要
  Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
2. At the prompts, provide the configuration details for your cloud:
  1. Optional: Select an SSH key to use to access your cluster machines.
    注意
    For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses.
  2. Select gcp as the platform to target.
  3. If you have not configured the service account key for your GCP account on your computer, you must obtain it from GCP and paste the contents of the file or enter the absolute path to the file.
  4. Select the project ID to provision the cluster in. The default value is specified by the service account that you configured.
  5. Select the region to deploy the cluster to.
  6. Select the base domain to deploy the cluster to. The base domain corresponds to the public DNS zone that you created for your cluster.
  7. Enter a descriptive name for your cluster.
  8. Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Modify the install-config.yaml file. You can find more information about the available parameters in the Installation configuration parameters section.
Back up the install-config.yaml file so that you can use it to install multiple clusters.
重要
The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now.

4.11.3.2. Creating the Kubernetes manifest and Ignition config files

重要

Prerequisites

Obtain the OpenShift Container Platform installation program. For a restricted network installation, these files are on your mirror host.
Create the install-config.yaml installation configuration file.

Procedure

Generate the Kubernetes manifests for the cluster:

Copy to Clipboard Toggle word wrap

./openshift-install create manifests --dir=<installation_directory>

$ ./openshift-install create manifests --dir=<installation_directory>

Example output

Copy to Clipboard Toggle word wrap

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

INFO Consuming Install Config from target directory
WARNING Making control-plane schedulable by setting MastersSchedulable to true for Scheduler cluster settings

1: For <installation_directory>, specify the installation directory that contains the install-config.yaml file you created.

Because you create your own compute machines later in the installation process, you can safely ignore this warning.

Remove the Kubernetes manifest files that define the control plane machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_master-machines-*.yaml
```
By removing these files, you prevent the cluster from automatically generating control plane machines.
Optional: If you do not want the cluster to provision compute machines, remove the Kubernetes manifest files that define the worker machines:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
```
$ rm -f <installation_directory>/openshift/99_openshift-cluster-api_worker-machineset-*.yaml
```
Because you create and manage the worker machines yourself, you do not need to initialize these machines.
Modify the <installation_directory>/manifests/cluster-scheduler-02-config.yml Kubernetes manifest file to prevent pods from being scheduled on the control plane machines:
1. Open the <installation_directory>/manifests/cluster-scheduler-02-config.yml file.
2. Locate the mastersSchedulable parameter and set its value to False.
3. Save and exit the file.

4.11.5. Creating a VPC in GCP

注意

Prerequisites

Configure a GCP account.
Generate the Ignition config files for your cluster.

Procedure

Copy the template from the Deployment Manager template for the VPC section of this topic and save it as 01_vpc.py on your computer. This template describes the VPC that your cluster requires.

Create a 01_vpc.yaml resource definition file:

Copy to Clipboard Toggle word wrap

cat <<EOF >01_vpc.yaml
imports:
- path: 01_vpc.py

resources:
- name: cluster-vpc
  type: 01_vpc.py
  properties:

4.11.6. Networking requirements for user-provisioned infrastructure

All the Red Hat Enterprise Linux CoreOS (RHCOS) machines require network in initramfs during boot to fetch Ignition config from the machine config server.

You must configure the network connectivity between machines to allow cluster components to communicate. Each machine must be able to resolve the host names of all other machines in the cluster.

Network topology requirements

The infrastructure that you provision for your cluster must meet the following network topology requirements.

Load balancers

Before you install OpenShift Container Platform, you must provision two load balancers that meet the following requirements:

API load balancer: Provides a common endpoint for users, both human and machine, to interact with and configure the platform. Configure the following conditions:
- Layer 4 load balancing only. This can be referred to as Raw TCP, SSL Passthrough, or SSL Bridge mode. If you use SSL Bridge mode, you must enable Server Name Indication (SNI) for the API routes.
