# Add CSI VolumeSnapshot support with snapshot support
|
|
|
|
Before we deploy snapshot-controller to actually **manage** the snapshots we take, we need the validation webhook to make sure it's done "right".

|
|
Already deployed:
|
|
|
|
* [x] A [Kubernetes cluster](/kubernetes/cluster/)
|
|
* [x] [Flux deployment process](/kubernetes/deployment/flux/) bootstrapped
|
|
* [x] [snapshot-validation-webhook](/kubernetes/backup/csi-snapshots/snapshot-validation-webhook/) deployed

#### Configure for rook-ceph
|
|
|
|
Under the HelmRelease values which you pasted from upstream, you'll note a section for `volumeSnapshotClasses`. By default, this is populated with commented out examples. To configure snapshot-controller to work with rook-ceph, replace these commented values as illustrated below:
|
|
|
|
```yaml title="/{{ page.meta.helmrelease_namespace }}/helmrelease-{{ page.meta.helmrelease_name }}.yaml (continued)"
|
|
values:
|
|
# extra content from upstream
|
|
volumeSnapshotClasses:
|
|
- name: csi-rbdplugin-snapclass
|
|
driver: rook-ceph.rbd.csi.ceph.com # driver:namespace:operator
|
|
labels:
|
|
velero.io/csi-volumesnapshot-class: "true"
|
|
parameters:
|
|
# Specify a string that identifies your cluster. Ceph CSI supports any
|
|
# unique string. When Ceph CSI is deployed by Rook use the Rook namespace,
|
|
# for example "rook-ceph".
|
|
clusterID: rook-ceph # namespace:cluster
|
|
csi.storage.k8s.io/snapshotter-secret-name: rook-csi-rbd-provisioner
|
|
csi.storage.k8s.io/snapshotter-secret-namespace: rook-ceph # namespace:cluster
|
|
deletionPolicy: Delete # docs suggest this may need to be set to "Retain" for restoring
|
|
```

## Summary
|
|
|
|
What have we achieved? We've got snapshot-controller running, and ready to manage VolumeSnapshots on behalf of Velero, for handy in-cluster volume backups!

|
* [X] snapshot-controller running and ready to snap :camera: !
|

|
|
Next:
|
|
|
|
* [ ] Configure [Velero](/kubernetes/backup/velero/) with a VolumeSnapshotLocation, so that volume snapshots can be made as part of a BackupSchedule!
