openshift-cluster-ocpv-vm-delete

A blueprint for safely removing Advanced Cluster Management from an OpenShift cluster

OpenShift VM Deletion Blueprint

This blueprint orchestrates the removal of virtual machines previously deployed on an OpenShift cluster with OpenShift Virtualization. It ensures proper cleanup of all VM resources.

Requirements

Parameters

  • openshift/ocpv-vm-namespace: Namespace containing VMs to delete
  • openshift/ocpv-vm-count: Number of VMs to delete (must match deployment)
  • openshift/ocpv-vm-name-prefix: Prefix for VM names to delete
  • openshift/ocpv-delete-namespace: Option to delete the namespace as well

Cluster Configuration

  • OpenShift Virtualization must be installed
  • VMs must have been previously deployed using the deployment blueprint

Usage

Select this blueprint from the cluster management menu when you need to remove virtual machines from your OpenShift cluster. Common scenarios include:

  • Cleaning up test environments
  • Reclaiming cluster resources
  • Removing unnecessary VM workloads
  • Resetting a deployment for redeployment

Deletion Process

The blueprint executes these tasks in sequence: 1. openshift-cluster-ocpv-delete-vm: - Identifies VMs based on prefix and count - Deletes VM resources - Deletes associated DataVolumes - Optionally deletes the namespace

Verification

After the blueprint completes, verify VM removal by checking: - VM absence in the OpenShift console - VM absence with oc get vm -n <namespace> - If namespace deletion was requested, verify namespace absence
