The OpenShift managed Kubernetes cluster contains a minimum of three control-plane and two or more worker nodes. Dell PowerFlex StorageClass is enabled for the Kubernetes cluster by configuring the PowerFlex CSI driver. The integration and discovery of the Red Hat OpenShift cluster assets are done on the PowerProtect Data Manager for data protection using the OpenShift API IP address.
Before integrating the Red Hat OpenShift cluster with PowerProtect Data Manager, ensure that the following requirements are met.
Steps to create a service account to register the Kubernetes cluster with PPDM using the RBAC option:
Figure 27. YAML files from the PowerProtect Data Manager UI
3. Follow the instructions in the README.txt as shown in the following figure to create the required clusterroles and clusterrolebindings, and to provide the token of the service account created in the YAML files. The README.txt file also provides instructions for manually creating the secret for the PPDM discovery service account, which is required in Kubernetes versions 1.24 and later.

From the PowerProtect Data Manager UI, select Infrastructure > Asset Sources, click Enable Source on the Kubernetes section.
The Kubernetes asset source must be enabled on PowerProtect Data Manager UI before adding and registering the asset source for the protection of assets.
Steps to enable the asset source:
Figure 29. Enable Asset Source
PowerProtect Data Manager enables the protection of Kubernetes environment by adding a Kubernetes cluster that is managed by Red Hat OpenShift as an asset source and discovering namespaces as assets for data protection operations.
Adding a Kubernetes cluster as an asset source in PowerProtect Data Manager enables the protection of namespaces and Persistent Volume Claims (PVCs) within the cluster.
Kubernetes cluster attributes:
Note: The use of any port other than 443 or 6443 requires opening the port on PowerProtect Data Manager first to enable outgoing communication, see the PowerProtect Data Manager Kubernetes User Guide.
The following figure shows the attributes of the Kubernetes cluster:

After adding the Red Hat OpenShift cluster, the cluster information appears in the table, and automatic discovery of namespace assets is initiated.
