Preface

Red Hat OpenShift Data Foundation supports deployment on existing Red Hat OpenShift Container Platform (RHOCP) Azure clusters.

Note

Only internal OpenShift Data Foundation clusters are supported on Microsoft Azure. See Planning your deployment for more information about deployment requirements.

To deploy OpenShift Data Foundation, start with the requirements in Preparing to deploy OpenShift Data Foundation chapter and then follow the appropriate deployment process based on your requirement:

Chapter 1. Preparing to deploy OpenShift Data Foundation

Deploying OpenShift Data Foundation on OpenShift Container Platform using dynamic storage devices provides you with the option to create internal cluster resources. This will result in the internal provisioning of the base services, which helps to make additional storage classes available to applications.

Before you begin the deployment of OpenShift Data Foundation, follow these steps:

  1. Setup a chrony server. See Configuring chrony time service and use knowledgebase solution to create rules allowing all traffic.
  2. Optional: If you want to enable cluster-wide encryption using an external Key Management System (KMS) then follow the steps:

  3. Minimum starting node requirements

    An OpenShift Data Foundation cluster is deployed with minimum configuration when the standard deployment resource requirement is not met. See Resource requirements section in Planning guide.

  4. Regional-DR requirements [Developer preview]

    Disaster Recovery features supported by Red Hat OpenShift Data Foundation require all of the following prerequisites in order to successfully implement a Disaster Recovery solution:

    For detailed requirements, see Regional-DR requirements and RHACM requirements.

Chapter 2. Deploying OpenShift Data Foundation on Microsoft Azure

You can deploy OpenShift Data Foundation on OpenShift Container Platform using dynamic storage devices provided by Microsoft Azure installer-provisioned infrastructure (IPI) (type: managed-premium) that enables you to create internal cluster resources. This results in internal provisioning of the base services, which helps to make additional storage classes available to applications.

Also, it is possible to deploy only the Multicloud Object Gateway (MCG) component with OpenShift Data Foundation. For more information, see Deploy standalone Multicloud Object Gateway.

Note

Only internal OpenShift Data Foundation clusters are supported on Microsoft Azure. See Planning your deployment for more information about deployment requirements.

Ensure that you have addressed the requirements in Preparing to deploy OpenShift Data Foundation chapter before proceeding with the below steps for deploying using dynamic storage devices:

2.1. Installing Red Hat OpenShift Data Foundation Operator

You can install Red Hat OpenShift Data Foundation Operator using the Red Hat OpenShift Container Platform Operator Hub.

Prerequisites

  • Access to an OpenShift Container Platform cluster using an account with cluster-admin and Operator installation permissions.
  • You must have at least three worker nodes in the Red Hat OpenShift Container Platform cluster.
  • For additional resource requirements, see the Planning your deployment guide.
Important
  • When you need to override the cluster-wide default node selector for OpenShift Data Foundation, you can use the following command in the command line interface to specify a blank node selector for the openshift-storage namespace (create openshift-storage namespace in this case):

    $ oc annotate namespace openshift-storage openshift.io/node-selector=
  • Taint a node as infra to ensure only Red Hat OpenShift Data Foundation resources are scheduled on that node. This helps you save on subscription costs. For more information, see How to use dedicated worker nodes for Red Hat OpenShift Data Foundation chapter in the Managing and Allocating Storage Resources guide.

Procedure

  1. Log in to the OpenShift Web Console.
  2. Click Operators → OperatorHub.
  3. Scroll or type OpenShift Data Foundation into the Filter by keyword box to find the OpenShift Data Foundation Operator.
  4. Click Install.
  5. Set the following options on the Install Operator page:

    1. Update Channel as stable-4.10.
    2. Installation Mode as A specific namespace on the cluster.
    3. Installed Namespace as Operator recommended namespace openshift-storage. If Namespace openshift-storage does not exist, it is created during the operator installation.
    4. Select Approval Strategy as Automatic or Manual.

      If you select Automatic updates, then the Operator Lifecycle Manager (OLM) automatically upgrades the running instance of your Operator without any intervention.

      If you select Manual updates, then the OLM creates an update request. As a cluster administrator, you must then manually approve that update request to update the Operator to a newer version.

    5. Ensure that the Enable option is selected for the Console plugin.
    6. Click Install.

Verification steps

  • After the operator is successfully installed, a pop-up with a message, Web console update is available appears on the user interface. Click Refresh web console from this pop-up for the console changes to reflect.
  • In the Web Console:

    • Navigate to Installed Operators and verify that the OpenShift Data Foundation Operator shows a green tick indicating successful installation.
    • Navigate to Storage and verify if Data Foundation dashboard is available.

2.2. Enabling cluster-wide encryption with KMS using the Token authentication method

To enable the key value backend path and policy in Vault for the Token authentication, follow the procedure:

Prerequisites

Procedure

  1. Enable the Key/Value (KV) backend path in Vault.

    For Vault KV secret engine API, version 1:

    $ vault secrets enable -path=odf kv

    For Vault KV secret engine API, version 2:

    $ vault secrets enable -path=odf kv-v2
  2. Create a policy to restrict users to perform a write or delete operation on the secret using the following commands.

    echo '
    path "odf/*" {
      capabilities = ["create", "read", "update", "delete", "list"]
    }
    path "sys/mounts" {
    capabilities = ["read"]
    }'| vault policy write odf -
  3. Create a token matching the above policy.

    $ vault token create -policy=odf -format json

2.3. Enabling cluster-wide encryption with KMS using the Kubernetes authentication method

You can enable the Kubernetes authentication method for cluster-wide encryption using the Key Management System (KMS).

Prerequisites

  • Administrator access to Vault.
  • A valid Red Hat OpenShift Data Foundation Advanced subscription. For more information, see the knowledgebase article on OpenShift Data Foundation subscriptions.
  • The OpenShift Data Foundation operator must be installed from the Operator Hub.
  • Select a unique path name as the backend path that follows the naming convention since it cannot be changed later.

    Note

    Use of Vault Namespaces is not supported with the Kubernetes authentication method in OpenShift Data Foundation 4.10

Procedure

  1. Create a service account:

    $ oc -n openshift-storage create serviceaccount <serviceaccount_name>

    where, <serviceaccount_name> specifies the name of the service account.

    For example:

    $ oc -n openshift-storage create serviceaccount odf-vault-auth
  2. Create clusterrolebindings and clusterroles:

    $ oc -n openshift-storage create clusterrolebinding vault-tokenreview-binding --clusterrole=system:auth-delegator --serviceaccount=openshift-storage:_<serviceaccount_name>_

    For example:

    $ oc -n openshift-storage create clusterrolebinding vault-tokenreview-binding --clusterrole=system:auth-delegator --serviceaccount=openshift-storage:odf-vault-auth
  3. Depending on the OpenShift Container Platform version, perform one of the following:

    • For OpenShift Container Platform 4.10:

      • Identify the secret name associated with the serviceaccount (SA) created above.

        $ VAULT_SA_SECRET_NAME=$(oc -n openshift-storage get sa <SA_NAME> -o jsonpath="{.secrets[*]['name']}") | grep -o "[^[:space:]]*-token-[^[:space:]]*"

        For example:

        $ VAULT_SA_SECRET_NAME=$(oc -n openshift-storage get sa odf-vault-auth -o jsonpath="{.secrets[*]['name']}" | grep -o "[^[:space:]]*-token-[^[:space:]]*")
    • For OpenShift Container Platform 4.11:

      • Create a secret for the serviceaccount token and CA certificate.

        $ cat <<EOF | oc create -f -
        apiVersion: v1
        kind: Secret
        metadata:
          name: odf-vault-auth-token
          namespace: openshift-storage
          annotations:
            kubernetes.io/service-account.name: <serviceaccount_name>
        type: kubernetes.io/service-account-token
        data: {}
        EOF

        where, <serviceaccount_name> is the service account created in the earlier step.

        $ VAULT_SA_SECRET_NAME=odf-vault-auth-token
  4. Get the token and the CA certificate from the secret.

    $ SA_JWT_TOKEN=$(oc -n openshift-storage get secret "$VAULT_SA_SECRET_NAME" -o jsonpath="{.data.token}" | base64 --decode; echo)
    $ SA_CA_CRT=$(oc -n openshift-storage get secret "$VAULT_SA_SECRET_NAME" -o jsonpath="{.data['ca\.crt']}" | base64 --decode; echo)
  5. Retrieve the OCP cluster endpoint.

    $ OCP_HOST=$(oc config view --minify --flatten -o jsonpath="{.clusters[0].cluster.server}")
  6. Fetch the service account issuer.

    $ oc proxy &
    $ proxy_pid=$!
    $ issuer="$( curl --silent http://127.0.0.1:8001/.well-known/openid-configuration | jq -r .issuer)"
    $ kill $proxy_pid
  7. Use the information collected in the steps above to setup the Kubernetes authentication method in Vault as shown below.

    $ vault auth enable kubernetes
    $ vault write auth/kubernetes/config \
              token_reviewer_jwt="$SA_JWT_TOKEN" \
              kubernetes_host="$OCP_HOST" \
              kubernetes_ca_cert="$SA_CA_CRT" \
              issuer="$issuer"
    Important

    To configure Kubernetes authentication method in Vault when the issuer is empty.

    $ vault write auth/kubernetes/config \
              token_reviewer_jwt="$SA_JWT_TOKEN" \
              kubernetes_host="$OCP_HOST" \
              kubernetes_ca_cert="$SA_CA_CRT"
  8. Enable the Key/Value (KV) backend path in Vault.

    For Vault KV secret engine API, version 1.

    $ vault secrets enable -path=odf kv

    For Vault KV secret engine API, version 2.

    $ vault secrets enable -path=odf kv-v2
  9. Create a policy to restrict users to perform a write or delete operation on the secret:

    echo '
    path "odf/*" {
      capabilities = ["create", "read", "update", "delete", "list"]
    }
    path "sys/mounts" {
    capabilities = ["read"]
    }'| vault policy write odf -
  10. Generate the roles:

    $ vault write auth/kubernetes/role/odf-rook-ceph-op \
            bound_service_account_names=rook-ceph-system,rook-ceph-osd,noobaa \
            bound_service_account_namespaces=openshift-storage \
            policies=odf \
            ttl=1440h

    The role odf-rook-ceph-op is later used while you configure the KMS connection details during the creation of the storage system.

    $ vault write auth/kubernetes/role/odf-rook-ceph-osd \
            bound_service_account_names=rook-ceph-osd \
            bound_service_account_namespaces=openshift-storage \
            policies=odf \
            ttl=1440h

Chapter 3. Deploying OpenShift Data Foundation on Azure Red Hat OpenShift

The Azure Red Hat OpenShift service enables you to deploy fully managed OpenShift clusters. Red Hat OpenShift Data Foundation can be deployed on Azure Red Hat OpenShift service.

Important

OpenShift Data Foundation on Azure Red Hat OpenShift is not a managed service offering. Red Hat OpenShift Data Foundation subscriptions are required to have the installation supported by the Red Hat support team. Open support cases by choosing the product as Red Hat OpenShift Data Foundation with the Red Hat support team (and not Microsoft) if you need any assistance for Red Hat OpenShift Data Foundation on Azure Red Hat OpenShift.

To install OpenShift Data Foundation on Azure Red Hat OpenShift, follow sections:

3.1. Getting a Red Hat pull secret for new deployment of Azure Red Hat OpenShift

A Red Hat pull secret enables the cluster to access Red Hat container registries along with additional content.

Prerequisites

  • A Red Hat portal account.
  • OpenShift Data Foundation subscription.

Procedure

To get a Red Hat pull secret for a new deployment of Azure Red Hat OpenShift, follow the steps in the section Get a Red Hat pull secret in the official Microsoft Azure documentation.

Note that while creating the Azure Red Hat OpenShift cluster, you may need larger worker nodes, controlled by --worker-vm-size or more worker nodes, controlled by --worker-count. The recommended worker-vm-size is Standard_D16s_v3. You can also use dedicated worker nodes, for more information, see How to use dedicated worker nodes for Red Hat OpenShift Data Foundation in the Managing and allocating storage resources guide.

3.2. Preparing a Red Hat pull secret for existing Azure Red Hat OpenShift clusters

When you create an Azure Red Hat OpenShift cluster without adding a Red Hat pull secret, a pull secret is still created on the cluster automatically. However, this pull secret is not fully populated.

Use this section to update the automatically created pull secret with the additional values from the Red Hat pull secret.

Prerequisites

  • Existing Azure Red Hat OpenShift cluster without a Red Hat pull secret.

Procedure

To prepare a Red Hat pull secret for existing an existing Azure Red Hat OpenShift clusters, follow the steps in the section Prepare your pull secret in the official Mircosoft Azure documentation.

3.3. Adding the pull secret to the cluster

Prerequisites

  • A Red Hat pull secret.

Procedure

  • Run the following command to update your pull secret.

    Note

    Running this command causes the cluster nodes to restart one by one as they are updated.

    oc set data secret/pull-secret -n openshift-config --from-file=.dockerconfigjson=./pull-secret.json

After the secret is set, you can enable the Red Hat Certified Operators.

3.3.1. Modifying the configuration files to enable Red Hat operators

To modify the configuration files to enable Red Hat operators, follow the steps in the section Modify the configuration files in the official Microsoft Azure documentation.

3.4. Validating your Red Hat pull secret is working

After you add the pull secret and modify the configuration files, the cluster can take several minutes to get updated.

To check if the cluster has been updated, run the following command to show the Certified Operators and Red Hat Operators sources available:

$ oc get catalogsource -A
NAMESPACE               NAME                  DISPLAY
openshift-marketplace   redhat-operators      Red Hat Operators

 TYPE   PUBLISHER   AGE
  grpc   Red Hat     11s

If you do not see the Red Hat Operators, wait a few minutes and try again.

To ensure that your pull secret has been updated and is working correctly, open Operator Hub and check for any Red Hat verified Operator. For example, check if the OpenShift Data Foundation Operator is available, and see if you have permissions to install it.

3.5. Installing Red Hat OpenShift Data Foundation Operator

Chapter 5. Deploy standalone Multicloud Object Gateway

Deploying only the Multicloud Object Gateway component with OpenShift Data Foundation provides the flexibility in deployment and helps to reduce the resource consumption. Use this section to deploy only the standalone Multicloud Object Gateway component, which involves the following steps:

  • Installing Red Hat OpenShift Data Foundation Operator
  • Creating standalone Multicloud Object Gateway

5.1. Installing Red Hat OpenShift Data Foundation Operator

You can install Red Hat OpenShift Data Foundation Operator using the Red Hat OpenShift Container Platform Operator Hub.

Prerequisites

  • Access to an OpenShift Container Platform cluster using an account with cluster-admin and Operator installation permissions.
  • You must have at least three worker nodes in the Red Hat OpenShift Container Platform cluster.
  • For additional resource requirements, see the Planning your deployment guide.
Important
  • When you need to override the cluster-wide default node selector for OpenShift Data Foundation, you can use the following command in the command line interface to specify a blank node selector for the openshift-storage namespace (create openshift-storage namespace in this case):

    $ oc annotate namespace openshift-storage openshift.io/node-selector=
  • Taint a node as infra to ensure only Red Hat OpenShift Data Foundation resources are scheduled on that node. This helps you save on subscription costs. For more information, see How to use dedicated worker nodes for Red Hat OpenShift Data Foundation chapter in the Managing and Allocating Storage Resources guide.

Procedure

  1. Log in to the OpenShift Web Console.
  2. Click Operators → OperatorHub.
  3. Scroll or type OpenShift Data Foundation into the Filter by keyword box to find the OpenShift Data Foundation Operator.
  4. Click Install.
  5. Set the following options on the Install Operator page:

    1. Update Channel as stable-4.10.
    2. Installation Mode as A specific namespace on the cluster.
    3. Installed Namespace as Operator recommended namespace openshift-storage. If Namespace openshift-storage does not exist, it is created during the operator installation.
    4. Select Approval Strategy as Automatic or Manual.

      If you select Automatic updates, then the Operator Lifecycle Manager (OLM) automatically upgrades the running instance of your Operator without any intervention.

      If you select Manual updates, then the OLM creates an update request. As a cluster administrator, you must then manually approve that update request to update the Operator to a newer version.

    5. Ensure that the Enable option is selected for the Console plugin.
    6. Click Install.

Verification steps

  • After the operator is successfully installed, a pop-up with a message, Web console update is available appears on the user interface. Click Refresh web console from this pop-up for the console changes to reflect.
  • In the Web Console:

    • Navigate to Installed Operators and verify that the OpenShift Data Foundation Operator shows a green tick indicating successful installation.
    • Navigate to Storage and verify if Data Foundation dashboard is available.

5.2. Creating a standalone Multicloud Object Gateway

You can create only the standalone Multicloud Object Gateway component while deploying OpenShift Data Foundation.

Prerequisites

  • Ensure that the OpenShift Data Foundation Operator is installed.

Procedure

  1. In the OpenShift Web Console, click OperatorsInstalled Operators to view all the installed operators.

    Ensure that the Project selected is openshift-storage.

  2. Click OpenShift Data Foundation operator and then click Create StorageSystem.
  3. In the Backing storage page, select the following:

    1. Select Multicloud Object Gateway for Deployment type.
    2. Select the Use an existing StorageClass option.
    3. Click Next.
  4. Optional: In the Security page, select Connect to an external key management service.

    1. Key Management Service Provider is set to Vault by default.
    2. Enter Vault Service Name, host Address of Vault server ('https://<hostname or ip>'), Port number, and Token.
    3. Expand Advanced Settings to enter additional settings and certificate details based on your Vault configuration:

      1. Enter the Key Value secret path in the Backend Path that is dedicated and unique to OpenShift Data Foundation.
      2. Optional: Enter TLS Server Name and Vault Enterprise Namespace.
      3. Upload the respective PEM encoded certificate file to provide the CA Certificate, Client Certificate, and Client Private Key.
      4. Click Save.
    4. Click Next.
  5. In the Review and create page, review the configuration details:

    To modify any configuration settings, click Back.

  6. Click Create StorageSystem.
