Create an Azure Red Hat OpenShift 4 cluster Application restore

In this article, you'll prepare your environment to create an Azure Red Hat OpenShift 4 cluster application restore. You'll learn how to:

[!div class="checklist"]

  • Setup the prerequisites and install the necessary tools
  • Create an Azure Red Hat OpenShift 4 application restore

If you choose to install and use the CLI locally, this tutorial requires that you're running the Azure CLI version 2.6.0 or later. Run az --version to find the version. If you need to install or upgrade, see Install Azure CLI.

Before you begin

Create an Azure Red Hat OpenShift 4 application backup

To create an Azure Red Hat OpenShift 4 application backup, see Create an Azure Red Hat OpenShift 4 backup

Restore an Azure Red Hat OpenShift 4 Application

These steps will allow you to restore an application that has been previously backed up with Velero. You can check the list of backups that are currently recognized by the cluster to see what backups are available for restore. To do this step, you'll need to execute the following command:

(This step assumes that you installed Velero in a project named "velero")

oc get backups -n velero

Once you have the backup that you would like to restore, you'll need to perform the restore with the following command:

velero restore create <name of restore> --from-backup <name of backup from above output list>

This step will create the Kubernetes objects that were backed up from the previous step when creating a backup.

To see the status of the restore, execute the following step:

oc get restore -n velero <name of restore created previously> -o yaml

When the phase says Completed, your Azure Red Hat 4 application should be restored.

Restore an Azure Red Hat OpenShift 4 Application with included snapshots

To create a restore of an Azure Red Hat OpenShift 4 application with persistent volumes using Velero, you'll need to perform the restore with the following command:

velero restore create <name of the restore> --from-backup <name of backup from above output list> --exclude-resources="nodes,events,events.events.k8s.io,backups.ark.heptio.com,backups.velero.io,restores.ark.heptio.com,restores.velero.io"

This step will create the Kubernetes objects that were backed up from the previous step when creating a backup.

To see the status of the restore, execute the following step:

oc get restore -n velero <name of restore created previously> -o yaml

When the phase says Completed, your Azure Red Hat 4 application should be restored.
