Using Ark with Portworx
Heptio Ark is a utility for managing disaster recovery, specifically for your Kubernetes cluster resources and persistent volumes. To take snapshots of Portworx volumes through Ark you need to install and configure the Portworx plugin.
Install Ark Plugin
Run the following command to install the Portworx plugin for Ark:
ark plugin add portworx/ark-plugin:0.5
This should add an init container to your Ark deployment to install the plugin.
Configure Ark to use Portworx snapshots
Once the plugin is installed, you need to create VolumeSnapshotLocation objects for ark to use when taking volume snapshots. These specify whether you want to take local or cloud snapshots.
apiVersion: ark.heptio.com/v1 kind: VolumeSnapshotLocation metadata: name: portworx-local namespace: heptio-ark spec: provider: portworx config: --- apiVersion: ark.heptio.com/v1 kind: VolumeSnapshotLocation metadata: name: portworx-cloud namespace: heptio-ark spec: provider: portworx config: type: cloud # Optional, required only if Portworx is configured with more than one credential credId: <UUID>
After applying the above specs you should see them when you list the VolumeSnapshotLocaions
kubectl get volumesnapshotlocation -n heptio-ark
NAME AGE portworx-cloud 54m portworx-local 54m
Once the plugin has been installed and configured, everytime you take backups using Ark and include PVCs, it will also take Portworx snapshots of your volumes.
To backup all your apps in the default namespace and also create local snapshots
of the volumes, you would use
portworx-local for the snapshot location:
$ ark backup create default-ns-local-backup --include-namespaces=default --snapshot-volumes \ --volume-snapshot-locations portworx-local Backup request "default-ns-local-backup" submitted successfully. Run `ark backup describe default-ns-local-backup` for more details.
To backup all your apps in the default namespace and also create cloud backups
of the volumes, you would use
portworx-cloud for the snapshot location:
$ ark backup create default-ns-cloud-backup --include-namespaces=default --snapshot-volumes \ --volume-snapshot-locations portworx-cloud Backup request "default-ns-cloud-backup" submitted successfully. Run `ark backup describe default-ns-cloud-backup` for more details.
Once the specs and volumes have been backed up you should see the backup marked
Completed in ark.
$ ark get backup NAME STATUS CREATED EXPIRES STORAGE LOCATION SELECTOR default-ns-local-backup Completed 2018-11-11 20:10:45 +0000 UTC 29d default <none> default-ns-cloud-backup Completed 2018-11-11 20:15:45 +0000 UTC 29d default <none>
Restoring from backups
When restoring from backups, a clone volume will be created from the snapshot and bound to the restored PVC. To restore from the backup created above you can run the following command:
$ ark restore create --from-backup default-ns-local-backup Restore request "default-ns-local-backup-20181111201245" submitted successfully. Run `ark restore describe default-ns-local-backup-20181111201245` for more details.
