Chapter 2. Detailed requirements for deploying Red Hat OpenShift Service on AWS
Red Hat OpenShift Service on AWS provides a model that allows Red Hat to deploy clusters into a customer’s existing Amazon Web Service (AWS) account.
Ensure that the following prerequisites are met before installing your cluster.
2.1. Customer requirements for all Red Hat OpenShift Service on AWS clusters Copia collegamentoCollegamento copiato negli appunti!
The following prerequisites must be complete before you deploy a Red Hat OpenShift Service on AWS cluster.
2.2. AWS account Copia collegamentoCollegamento copiato negli appunti!
- Your AWS account must allow sufficient quota to deploy your cluster.
- If your organization applies and enforces SCP policies, these policies must not be more restrictive than the roles and policies required by the cluster.
- You can deploy native AWS services within the same AWS account.
- Your account must have a service-linked role to allow the installation program to configure Elastic Load Balancing (ELB). See "Creating the Elastic Load Balancing (ELB) service-linked role" for more information.
2.2.1. Support requirements Copia collegamentoCollegamento copiato negli appunti!
- Red Hat recommends that the customer have at least Business Support from AWS.
- Red Hat may have permission from the customer to request AWS support on their behalf.
- Red Hat may have permission from the customer to request AWS resource limit increases on the customer’s account.
- Red Hat manages the restrictions, limitations, expectations, and defaults for all Red Hat OpenShift Service on AWS clusters in the same manner, unless otherwise specified in this requirements section.
2.2.2. Security requirements Copia collegamentoCollegamento copiato negli appunti!
- Red Hat must have ingress access to EC2 hosts and the API server from allow-listed IP addresses.
- Red Hat must have egress allowed to the domains documented in the "Firewall prerequisites" section. Clusters with egress zero are exempt from this requirement.
2.3. Requirements for using OpenShift Cluster Manager Copia collegamentoCollegamento copiato negli appunti!
The following configuration details are required only if you use OpenShift Cluster Manager to manage your clusters. If you use the CLI tools exclusively, then you can disregard these requirements.
2.3.1. AWS account association Copia collegamentoCollegamento copiato negli appunti!
When you provision Red Hat OpenShift Service on AWS using OpenShift Cluster Manager (console.redhat.com
), you must associate the ocm-role
and user-role
IAM roles with your AWS account using your Amazon Resource Name (ARN). This association process is also known as account linking.
The ocm-role
ARN is stored as a label in your Red Hat organization while the user-role
ARN is stored as a label inside your Red Hat user account. Red Hat uses these ARN labels to confirm that the user is a valid account holder and that the correct permissions are available to perform provisioning tasks in the AWS account.
2.3.2. Associating your AWS account with IAM roles Copia collegamentoCollegamento copiato negli appunti!
You can associate or link your AWS account with existing IAM roles by using the ROSA CLI, rosa
.
Prerequisites
- You have an AWS account.
- You have the permissions required to install AWS account-wide roles. See the "Additional resources" of this section for more information.
-
You have installed and configured the latest AWS (
aws
) and ROSA (rosa
) CLIs on your installation host. You have created the
ocm-role
anduser-role
IAM roles, but have not yet linked them to your AWS account. You can check whether your IAM roles are already linked by running the following commands:rosa list ocm-role
$ rosa list ocm-role

Yes
is displayed in theLinked
column for both roles, you have already linked the roles to an AWS account.
Procedure
In the ROSA CLI, link your
ocm-role
resource to your Red Hat organization by using your Amazon Resource Name (ARN):NoteYou must have Red Hat Organization Administrator privileges to run the
rosa link
command. After you link theocm-role
resource with your AWS account, it takes effect and is visible to all users in the organization.rosa link ocm-role --role-arn <arn>

2.3.3. Associating multiple AWS accounts with your Red Hat organization Copia collegamentoCollegamento copiato negli appunti!
You can associate multiple AWS accounts with your Red Hat organization. Associating multiple accounts lets you create Red Hat OpenShift Service on AWS clusters on any of the associated AWS accounts from your Red Hat organization.
With this capability, you can create clusters on different AWS profiles according to characteristics that make sense for your business, for example, by using one AWS profile for each region to create region-bound environments.
Prerequisites
- You have an AWS account.
- You are using OpenShift Cluster Manager to create clusters.
- You have the permissions required to install AWS account-wide roles.
-
You have installed and configured the latest AWS (
aws
) and ROSA (rosa
) CLIs on your installation host. -
You have created the
ocm-role
anduser-role
IAM roles for Red Hat OpenShift Service on AWS.
Procedure
To associate an additional AWS account, first create a profile in your local AWS configuration. Then, associate the account with your Red Hat organization by creating the ocm-role
, user, and account roles in the additional AWS account.
To create the roles in an additional region, specify the --profile <aws-profile>
parameter when running the rosa create
commands and replace <aws_profile>
with the additional account profile name:
To specify an AWS account profile when creating an OpenShift Cluster Manager role:

If you do not specify a profile, the default AWS profile and its associated AWS region are used.
2.4. Requirements for deploying a cluster in an opt-in region Copia collegamentoCollegamento copiato negli appunti!
An AWS opt-in region is a region that is not enabled in your AWS account by default. If you want to deploy a Red Hat OpenShift Service on AWS cluster that uses the AWS Security Token Service (STS) in an opt-in region, you must meet the following requirements:
- The region must be enabled in your AWS account. For more information about enabling opt-in regions, see Managing AWS Regions in the AWS documentation.
The security token version in your AWS account must be set to version 2. You cannot use version 1 security tokens for opt-in regions.
ImportantUpdating to security token version 2 can impact the systems that store the tokens, due to the increased token length. For more information, see the AWS documentation on setting STS preferences.
2.4.1. Setting the AWS security token version Copia collegamentoCollegamento copiato negli appunti!
If you want to create a Red Hat OpenShift Service on AWS cluster with the AWS Security Token Service (STS) in an AWS opt-in region, you must set the security token version to version 2 in your AWS account.
Prerequisites
- You have installed and configured the latest AWS CLI on your installation host.
Procedure
List the ID of the AWS account that is defined in your AWS CLI configuration:
aws sts get-caller-identity --query Account --output json
$ aws sts get-caller-identity --query Account --output json

Copy to Clipboard Copied! Toggle word wrap Toggle overflow ImportantUpdating to security token version 2 can impact the systems that store the tokens, due to the increased token length. For more information, see the AWS documentation on setting STS preferences.
2.5. Red Hat managed IAM references for AWS Copia collegamentoCollegamento copiato negli appunti!
Red Hat is not responsible for creating and managing Amazon Web Services (AWS) IAM policies, IAM users, or IAM roles. For information on creating these roles and policies, see the following sections on IAM roles.
-
To use the
ocm
CLI, you must have anocm-role
anduser-role
resource. See Required IAM roles and resources. - If you have a single cluster, see Account-wide IAM role and policy reference.
- For each cluster, you must have the necessary Operator roles. See Cluster-specific Operator IAM role reference.
2.6. Provisioned AWS Infrastructure Copia collegamentoCollegamento copiato negli appunti!
This is an overview of the provisioned Amazon Web Services (AWS) components on a deployed Red Hat OpenShift Service on AWS cluster.
2.6.1. EC2 instances Copia collegamentoCollegamento copiato negli appunti!
AWS EC2 instances are required to deploy Red Hat OpenShift Service on AWS.
At a minimum, two m5.xlarge
EC2 instances are deployed for use as worker nodes.
The instance type shown for worker nodes is the default value, but you can customize the instance type for worker nodes according to the needs of your workload.
2.6.2. Amazon Elastic Block Store storage Copia collegamentoCollegamento copiato negli appunti!
Amazon Elastic Block Store (Amazon EBS) block storage is used for both local node storage and persistent volume storage. By default, the following storage is provisioned for each EC2 instance:
Node volumes
-
Type:
AWS EBS GP3
- Default size: 300 GiB (adjustable at creation time)
- Minimum size: 75 GiB
-
Type:
Workload persistent volumes
-
Default storage class:
gp3-csi
-
Provisioner:
ebs.csi.aws.com
- Dynamic persistent volume provisioning
-
Default storage class:
2.6.3. Elastic Load Balancing Copia collegamentoCollegamento copiato negli appunti!
By default, one Network Load Balancer is created for use by the default ingress controller. You can create additional load balancers of the following types according to the needs of your workload:
- Classic Load Balancer
- Network Load Balancer
- Application Load Balancer
For more information, see the ELB documentation for AWS.
2.6.4. S3 storage Copia collegamentoCollegamento copiato negli appunti!
The image registry is backed by AWS S3 storage. Resources are pruned regularly to optimize S3 usage and cluster performance.
Two buckets are required with a typical size of 2TB each.
2.6.5. VPC Copia collegamentoCollegamento copiato negli appunti!
Configure your VPC according to the following requirements:
Subnets: Every cluster requires a minimum of one private subnet for every availability zone. For example, 1 private subnet is required for a single-zone cluster, and 3 private subnets are required for a cluster with 3 availability zones.
If your cluster needs direct access to a network that is external to the cluster, including the public internet, you require at least one public subnet.
Red Hat strongly recommends using unique subnets for each cluster. Sharing subnets between multiple clusters is not recommended.
NoteA public subnet connects directly to the internet through an internet gateway.
A private subnet connects to the internet through a network address translation (NAT) gateway.
- Route tables: One route table per private subnet, and one additional table per cluster.
- Internet gateways: One Internet Gateway per cluster.
- NAT gateways: One NAT Gateway per public subnet.
2.6.6. Security groups Copia collegamentoCollegamento copiato negli appunti!
AWS security groups provide security at the protocol and port access level; they are associated with EC2 instances and Elastic Load Balancing (ELB) load balancers. Each security group contains a set of rules that filter traffic coming in and out of one or more EC2 instances.
Ensure that the ports required for cluster installation and operation are open on your network and configured to allow access between hosts. The requirements for the default security groups are listed in Required ports for default security groups.
Group | Type | IP Protocol | Port range |
---|---|---|---|
WorkerSecurityGroup |
|
|
|
|
|
2.6.6.1. Additional custom security groups Copia collegamentoCollegamento copiato negli appunti!
You can add additional custom security groups during cluster creation. Custom security groups are subject to the following limitations:
- You must create the custom security groups in AWS before you create the cluster. For more information, see Amazon EC2 security groups for Linux instances.
- You must associate the custom security groups with the VPC that the cluster will be installed into. Your custom security groups cannot be associated with another VPC.
- You might need to request additional quota for your VPC if you are adding additional custom security groups. For information on AWS quota requirements for Red Hat OpenShift Service on AWS see Required AWS service quotas in Prepare your environment. For information on requesting an AWS quota increase, see Requesting a quota increase.
2.7. Networking prerequisites Copia collegamentoCollegamento copiato negli appunti!
2.7.1. Minimum bandwidth Copia collegamentoCollegamento copiato negli appunti!
During cluster deployment, Red Hat OpenShift Service on AWS requires a minimum bandwidth of 120 Mbps between cluster infrastructure and the public internet or private network locations that provide deployment artifacts and resources. When network connectivity is slower than 120 Mbps (for example, when connecting through a proxy) the cluster installation process times out and deployment fails.
After cluster deployment, network requirements are determined by your workload. However, a minimum bandwidth of 120 Mbps helps to ensure timely cluster and operator upgrades.
2.7.2. AWS firewall prerequisites Copia collegamentoCollegamento copiato negli appunti!
If you are using a firewall to control egress traffic from your Red Hat OpenShift Service on AWS cluster, you must configure your firewall to grant access to the certain domain and port combinations below. Red Hat OpenShift Service on AWS requires this access to provide a fully managed OpenShift service.
Prerequisites
- You have configured an Amazon S3 gateway endpoint in your AWS Virtual Private Cloud (VPC). This endpoint is required to complete requests from the cluster to the Amazon S3 service.
