24 | | -In the Beta version, the snapshot controller will be watching the Kubernetes API server for `VolumeSnapshot` and `VolumeSnapshotContent` CRD objects. The CSI `external-snapshotter` sidecar only watches the Kubernetes API server for `VolumeSnapshotContent` CRD objects. The CSI `external-snapshotter` sidecar is also responsible for calling the CSI RPCs CreateSnapshot, DeleteSnapshot, and ListSnapshots. |
