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: Deploy OpenShift Data Foundation on Microsoft Azure Deploy standalone Multicloud Object Gateway component 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: Setup a chrony server. See Configuring chrony time service and use knowledgebase solution to create rules allowing all traffic. Optional: If you want to enable cluster-wide encryption using the external Key Management System (KMS) HashiCorp Vault, follow these steps: Ensure that you have a valid Red Hat OpenShift Data Foundation Advanced subscription. To know how subscriptions for OpenShift Data Foundation work, see knowledgebase article on OpenShift Data Foundation subscriptions . When the Token authentication method is selected for encryption then refer to Enabling cluster-wide encryption with the Token authentication using KMS . When the Kubernetes authentication method is selected for encryption then refer to Enabling cluster-wide encryption with the Kubernetes authentication using KMS . Ensure that you are using signed certificates on your Vault servers. Note If you are using Thales CipherTrust Manager as your KMS, you will enable it during deployment. 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. Disaster recovery requirements Disaster Recovery features supported by Red Hat OpenShift Data Foundation require all of the following prerequisites to successfully implement a disaster recovery solution: A valid Red Hat OpenShift Data Foundation Advanced subscription A valid Red Hat Advanced Cluster Management for Kubernetes subscription To know how subscriptions for OpenShift Data Foundation work, see knowledgebase article on OpenShift Data Foundation subscriptions . For detailed requirements, see Configuring OpenShift Data Foundation Disaster Recovery for OpenShift Workloads guide, and Requirements and recommendations section of the Install guide in Red Hat Advanced Cluster Management for Kubernetes documentation. 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-csi ) 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: Install the Red Hat OpenShift Data Foundation Operator . Create the OpenShift Data Foundation Cluster 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 or infrastructure 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 to specify a blank node selector for the openshift-storage namespace (create openshift-storage namespace in this case): 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 the How to use dedicated worker nodes for Red Hat OpenShift Data Foundation section in the Managing and Allocating Storage Resources guide. Procedure Log in to the OpenShift Web Console. Click Operators -> OperatorHub . Scroll or type OpenShift Data Foundation into the Filter by keyword box to find the OpenShift Data Foundation Operator. Click Install . Set the following options on the Install Operator page: Update Channel as stable-4.18 . Installation Mode as A specific namespace on the cluster . Installed Namespace as Operator recommended namespace openshift-storage . If Namespace openshift-storage does not exist, it is created during the operator installation. 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. Ensure that the Enable option is selected for the Console plugin . 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 the Data Foundation dashboard is available. 2.2. Enabling cluster-wide encryption with KMS using the Token authentication method You can enable the key value backend path and policy in the vault for token authentication. Prerequisites Administrator access to the vault. A valid Red Hat OpenShift Data Foundation Advanced subscription. For more information, see the knowledgebase article on OpenShift Data Foundation subscriptions . Carefully, select a unique path name as the backend path that follows the naming convention since you cannot change it later. Procedure Enable the Key/Value (KV) backend path in the vault. For vault KV secret engine API, version 1: For vault KV secret engine API, version 2: Create a policy to restrict the users to perform a write or delete operation on the secret: Create a token that matches the above policy: 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 carefully. You cannot change this path name later. Procedure Create a service account: where, <serviceaccount_name> specifies the name of the service account. For example: Create clusterrolebindings and clusterroles : For example: Create a secret for the serviceaccount token and CA certificate. where, <serviceaccount_name> is the service account created in the earlier step. Get the token and the CA certificate from the secret. Retrieve the OCP cluster endpoint. Fetch the service account issuer: Use the information collected in the step to setup the Kubernetes authentication method in Vault: Important To configure the Kubernetes authentication method in Vault when the issuer is empty: Enable the Key/Value (KV) backend path in Vault. For Vault KV secret engine API, version 1: For Vault KV secret engine API, version 2: Create a policy to restrict the users to perform a write or delete operation on the secret: Generate the roles: The role odf-rook-ceph-op is later used while you configure the KMS connection details during the creation of the storage system. 2.3.1. Enabling and disabling key rotation when using KMS Security common practices require periodic encryption of key rotation. You can enable or disable key rotation when using KMS. 2.3.1.1. Enabling key rotation To enable key rotation, add the annotation keyrotation.csiaddons.openshift.io/schedule: <value> to PersistentVolumeClaims , Namespace , or StorageClass (in the decreasing order of precedence). <value> can be @hourly , @daily , @weekly , @monthly , or @yearly . If <value> is empty, the default is @weekly . The below examples use @weekly . Important Key rotation is only supported for RBD backed volumes. Annotating Namespace Annotating StorageClass Annotating PersistentVolumeClaims 2.3.1.2. Disabling key rotation You can disable key rotation for the following: All the persistent volume claims (PVCs) of storage class A specific PVC Disabling key rotation for all PVCs of a storage class To disable key rotation for all PVCs, update the annotation of the storage class: Disabling key rotation for a specific persistent volume claim Identify the EncryptionKeyRotationCronJob CR for the PVC you want to disable key rotation on: Where <PVC_NAME> is the name of the PVC that you want to disable. Apply the following to the EncryptionKeyRotationCronJob CR from the step to disable the key rotation: Update the csiaddons.openshift.io/state annotation from managed to unmanaged : Where <encryptionkeyrotationcronjob_name> is the name of the EncryptionKeyRotationCronJob CR. Add suspend: true under the spec field: Save and exit. The key rotation will be disabled for the PVC. 2.4.

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 or infrastructure 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 to specify a blank node selector for the openshift-storage namespace (create openshift-storage namespace in this case): 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 the How to use dedicated worker nodes for Red Hat OpenShift Data Foundation section in the Managing and Allocating Storage Resources guide. Procedure Log in to the OpenShift Web Console. Click Operators -> OperatorHub . Scroll or type OpenShift Data Foundation into the Filter by keyword box to find the OpenShift Data Foundation Operator. Click Install . Set the following options on the Install Operator page: Update Channel as stable-4.18 . Installation Mode as A specific namespace on the cluster . Installed Namespace as Operator recommended namespace openshift-storage . If Namespace openshift-storage does not exist, it is created during the operator installation. 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. Ensure that the Enable option is selected for the Console plugin . 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 the Data Foundation dashboard is available. 5.2. Creating a standalone Multicloud Object Gateway You can create only the standalone Multicloud Object Gateway (MCG) component while deploying OpenShift Data Foundation. After you create the MCG component, you can create and manage buckets using the MCG object browser. For more information, see Creating and managing buckets using MCG object browser . Prerequisites Ensure that the OpenShift Data Foundation Operator is installed. Procedure In the OpenShift Web Console, click Operators -> Installed Operators to view all the installed operators. Ensure that the Project selected is openshift-storage . Click OpenShift Data Foundation operator and then click Create StorageSystem . In the Backing storage page, select the following: Select Multicloud Object Gateway for Deployment type . Select the Use an existing StorageClass option. Click . Optional: Select the Connect to an external key management service checkbox. This is optional for cluster-wide encryption. From the Key Management Service Provider drop-down list, either select Vault or Thales CipherTrust Manager (using KMIP) . If you selected Vault , go to the step. If you selected Thales CipherTrust Manager (using KMIP) , go to step iii. Select an Authentication Method . Using Token authentication method Enter a unique Connection Name , host Address of the Vault server ('https://<hostname or ip>'), Port number and Token . Expand Advanced Settings to enter additional settings and certificate details based on your Vault configuration: Enter the Key Value secret path in Backend Path that is dedicated and unique to OpenShift Data Foundation. Optional: Enter TLS Server Name and Vault Enterprise Namespace . Upload the respective PEM encoded certificate file to provide the CA Certificate , Client Certificate and Client Private Key . Click Save and skip to step iv. Using Kubernetes authentication method Enter a unique Vault Connection Name , host Address of the Vault server ('https://<hostname or ip>'), Port number and Role name. Expand Advanced Settings to enter additional settings and certificate details based on your Vault configuration: Enter the Key Value secret path in Backend Path that is dedicated and unique to OpenShift Data Foundation. Optional: Enter TLS Server Name and Authentication Path if applicable. Upload the respective PEM encoded certificate file to provide the CA Certificate , Client Certificate and Client Private Key . Click Save and skip to step iv. To use Thales CipherTrust Manager (using KMIP) as the KMS provider, follow the steps below: Enter a unique Connection Name for the Key Management service within the project. In the Address and Port sections, enter the IP of Thales CipherTrust Manager and the port where the KMIP interface is enabled. For example: Address : 123.34.3.2 Port : 5696 Upload the Client Certificate , CA certificate , and Client Private Key . If StorageClass encryption is enabled, enter the Unique Identifier to be used for encryption and decryption generated above. The TLS Server field is optional and used when there is no DNS entry for the KMIP endpoint. For example, kmip_all_<port>.ciphertrustmanager.local . Select a Network . Click . In the Review and create page, review the configuration details: To modify any configuration settings, click Back . Click Create StorageSystem . Verification steps Verifying that the OpenShift Data Foundation cluster is healthy In the OpenShift Web Console, click Storage -> Data Foundation . In the Status card of the Overview tab, click Storage System and then click the storage system link from the pop up that appears. In the Status card of the Object tab, verify that both Object Service and Data Resiliency have a green tick. In the Details card, verify that the MCG information is displayed. Verifying the state of the pods Click Workloads -> Pods from the OpenShift Web Console. Select openshift-storage from the Project drop-down list and verify that the following pods are in Running state. Note If the Show default projects option is disabled, use the toggle button to list all the default projects. Component Corresponding pods OpenShift Data Foundation Operator ocs-operator-* (1 pod on any storage node) ocs-metrics-exporter-* (1 pod on any storage node) odf-operator-controller-manager-* (1 pod on any storage node) odf-console-* (1 pod on any storage node) csi-addons-controller-manager-* (1 pod on any storage node) Rook-ceph Operator rook-ceph-operator-* (1 pod on any storage node) Multicloud Object Gateway noobaa-operator-* (1 pod on any storage node) noobaa-core-* (1 pod on any storage node) noobaa-db-pg-* (1 pod on any storage node) noobaa-endpoint-* (1 pod on any storage node) Chapter 6. View OpenShift Data Foundation Topology The topology shows the mapped visualization of the OpenShift Data Foundation storage cluster at various abstraction levels and also lets you to interact with these layers. The view also shows how the various elements compose the Storage cluster altogether. Procedure On the OpenShift Web Console, navigate to Storage -> Data Foundation -> Topology . The view shows the storage cluster and the zones inside it. You can see the nodes depicted by circular entities within the zones, which are indicated by dotted lines. The label of each item or resource contains basic information such as status and health or indication for alerts. Choose a node to view node details on the right-hand panel. You can also access resources or deployments within a node by clicking on the search/preview decorator icon. To view deployment details Click the preview decorator on a node. A modal window appears above the node that displays all of the deployments associated with that node along with their statuses. Click the Back to main view button in the model's upper left corner to close and return to the view. Select a specific deployment to see more information about it. All relevant data is shown in the side panel. Click the Resources tab to view the pods information. This tab provides a deeper understanding of the problems and offers granularity that aids in better troubleshooting. Click the pod links to view the pod information page on OpenShift Container Platform. The link opens in a new window. Chapter 7. Uninstalling OpenShift Data Foundation 7.1.
