Deleting a Kubernetes Cluster

Deleting a Kubernetes cluster will remove the cluster from the deployment, as follows:

Local cluster
Any tenants or pods that are currently running will be terminated, and no output will be captured.
External cluster
The cluster information is removed from the deployment, but the cluster itself and all tenants/pods therein remain unchanged. You can re-import this cluster as described in Importing an External Kubernetes Cluster.
Data Fabric cluster
  • You cannot delete a Data Fabric cluster after it has been registered, as described in HPE Ezmeral Data Fabric as Tenant/Persistent Storage.
  • Deleting the Data Fabric cluster also deletes the HPE Ezmeral Data Fabric for that cluster. You will receive a confirmation message before this type of cluster can be deleted.
  • After you delete a Data Fabric cluster, you must reboot the Kubernetes hosts before the hosts can be reused in HPE Ezmeral Runtime Enterprise.

To delete a Kubernetes cluster:

  1. Open the Kubernetes Clusters screen.
  2. Select the cluster to delete, and then click the Delete icon (trash can) for that cluster in the Actions column.
  3. A popup warning appears asking you to confirm or cancel the action. Click OK to proceed, or Cancel to exit without deleting the cluster.
  4. If you deleted a Data Fabric cluster, reboot the Kubernetes hosts that were part of the Data Fabric cluster.

You cannot undelete a Kubernetes cluster. Deleting a Kubernetes cluster immediately ends any tenant(s) and pod(s) running on that cluster.
