Configure backup with the integrated Kubernetes registry

Configure the DevWorkspace backup to use the integrated Kubernetes container registry, available on clusters with the integrated container registry enabled. This option requires no additional credentials configuration.

Prerequisites

An active kubectl session with administrative permissions to the destination Kubernetes cluster. See Overview of kubectl.
The integrated container registry is enabled on the cluster.

To enable the backup use following configuration in the global DWOC:

apiVersion: controller.devfile.io/v1alpha1
kind: DevWorkspaceOperatorConfig
metadata:
  name: devworkspace-operator-config
  namespace: $OPERATOR_INSTALL_NAMESPACE (1)
config:
  routing:
    defaultRoutingClass: basic
  workspace:
    backupCronJob:
      enable: true
      registry:
        path: default-route-openshift-image-registry.apps.{cluster ID}.openshiftapps.com
      oras:
        extraArgs: '--insecure' (2)
      schedule: '0 */4 * * *' # cron expression with backup frequency
    imagePullPolicy: Always

1	For Red Hat OpenShift, the default installation namespace for the DevWorkspace operator is `openshift-operators`. See the DevWorkspace operator overview.
2	The `--insecure` flag can be required depending on the integrated registry’s routing configuration.

Note: The path field must contain the URL to your OpenShift integrated registry given by the cluster.

To get a default path to registry run following command:

echo "https://$(oc get route default-route -n openshift-image-registry --template='{{ .spec.host }}'))"

Once the backup job is finished, the backup archives will be available in the DevWorkspace namespace under a repository with a matching DevWorkspace name.

If the installation namespace for the DevWorkspace operator is not openshift-operators, you must define it as an environment variable for the Eclipse Che dashboard in the CheCluster Custom Resource.

apiVersion: org.eclipse.che/v2
kind: CheCluster
spec:
  components:
    dashboard:
      deployment:
        containers:
          - env:
              - name: DWO_NAMESPACE
                value: $OPERATOR_INSTALL_NAMESPACE (1)
            name: che-dashboard

1	For Red Hat OpenShift, the default installation namespace for the DevWorkspace operator is `openshift-operators`. See the DevWorkspace operator overview.
