Backup OpenShift Releases

The OpenShift cluster can be stored and restored to reduce the installation time. The restoration of the cluster hardly takes seven minutes to initialize the cluster.

How it works

To store the cluster, onp takes the below actions.

• Gracefully shuts down the cluster.

• Copy the virtual machine disk to another location.

• Copy the kubeconfig and kubeadmin-password files to another location.

The restoration takes the reverse and waits for the cluster to initialize properly.

INFO

Check if there is any pending CSR and approve it when the cluster initializes.
