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: Getting a Red Hat pull secret for new deployment of Azure Red Hat OpenShift . Preparing a Red Hat pull secret for existing Azure Red Hat OpenShift clusters . Adding the pull secret to the cluster . Validating your Red Hat pull secret is working . Install the Red Hat OpenShift Data Foundation Operator . Create the OpenShift Data Foundation Cluster Service . 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. 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: If you do not see the Red Hat Operators, wait for 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 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. 3.6. Creating OpenShift Data Foundation cluster Create an OpenShift Data Foundation cluster after you install the OpenShift Data Foundation operator. Prerequisites The OpenShift Data Foundation operator must be installed from the Operator Hub. For more information, see Installing OpenShift Data Foundation Operator using the Operator Hub . If you want to use Azure Vault as the key management service provider, make sure to set up client authentication and fetch the client credentials from Azure using the following steps: Create Azure Vault. For more information, see Quickstart: Create a key vault using the Azure portal in Microsoft product documentation. Create Service Principal with certificate based authentication. For more information, see Create an Azure service principal with Azure CLI in Microsoft product documentation. Set Azure Key Vault role based access control (RBAC). For more information, see Enable Azure RBAC permissions on Key Vault 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 on the OpenShift Data Foundation operator, and then click Create StorageSystem . In the Backing storage page, select the following: Select Full Deployment for the Deployment type option. Select the Use an existing StorageClass option. Select the Storage Class . By default, it is set to managed-csi . Optional: Select Use external PostgreSQL checkbox to use an external PostgreSQL [Technology preview] . This provides high availability solution for Multicloud Object Gateway where the PostgreSQL pod is a single point of failure. Provide the following connection details: Username Password Server name and Port Database name Select Enable TLS/SSL checkbox to enable encryption for the Postgres server. Click . In the Capacity and nodes page, provide the necessary information: Select a value for Requested Capacity from the dropdown list. It is set to 2 TiB by default. Note Once you select the initial storage capacity, cluster expansion is performed only using the selected usable capacity (three times of raw storage). In the Select Nodes section, select at least three available nodes. In the Configure performance section, select one of the following performance profiles: Lean Use this in a resource constrained environment with minimum resources that are lower than the recommended. This profile minimizes resource consumption by allocating fewer CPUs and less memory. Balanced (default) Use this when recommended resources are available. This profile provides a balance between resource consumption and performance for diverse workloads. Performance Use this in an environment with sufficient resources to get the best performance. This profile is tailored for high performance by allocating ample memory and CPUs to ensure optimal execution of demanding workloads. Note You have the option to configure the performance profile even after the deployment using the Configure performance option from the options menu of the StorageSystems tab. Important Before selecting a resource profile, make sure to check the current availability of resources within the cluster. Opting for a higher resource profile in a cluster with insufficient resources might lead to installation failures. For more information about resource requirements, see Resource requirement for performance profiles . Optional: Select the Taint nodes checkbox to dedicate the selected nodes for OpenShift Data Foundation. For cloud platforms with multiple availability zones, ensure that the Nodes are spread across different Locations/availability zones. If the nodes selected do not match the OpenShift Data Foundation cluster requirements of an aggregated 30 CPUs and 72 GiB of RAM, a minimal cluster is deployed. For minimum starting node requirements, see the Resource requirements section in the Planning guide. Click . Optional: In the Security and network page, configure the following based on your requirements: To enable encryption, select Enable data encryption for block and file storage . Select either one or both the encryption levels: Cluster-wide encryption Encrypts the entire cluster (block and file). StorageClass encryption Creates encrypted persistent volume (block only) using encryption enabled storage class. 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, select one of the following providers and provide the necessary details: Vault 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 .
