It is part of a larger [plan](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/1900-volume-snapshot-validation-webhook#proposal) to tighten validation for volume snapshot objects. This webhook introduces the [ratcheting validation](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/1900-volume-snapshot-validation-webhook#backwards-compatibility) mechanism targeting the tighter validation. The cluster admin or Kubernetes distribution admin should install the webhook alongside the snapshot controllers and CRDs. > :warning: **WARNING**: Cluster admins choosing not to install the webhook server and participate in the phased release process can cause future problems when upgrading from `v1beta1` to `v1` volumesnapshot API, if there are currently persisted objects which fail the new stricter validation. Potential impacts include being unable to delete invalid snapshot objects.
