CNV — Patch Workflow

Patching workflow for RHEL VMs running on OpenShift Virtualization. Similar to the cloud patching workflow but targeting CNV-managed virtual machines instead of EC2 instances.

  1. Take Snapshot — Creates VM snapshots for recovery
  2. Project Sync + Inventory Sync (parallel) — Refreshes project content and CNV inventory
  3. Patch Instance — Applies patches to CNV RHEL VMs
  4. Restore (on failure) — Restores VMs from snapshot if patching fails
  5. Ticket (on restore failure) — Creates a notification if restore also fails

Prerequisites

  • RHEL VMs provisioned on OpenShift CNV
  • OpenShift Credential configured
  • SSH connectivity to the CNV VMs
