The Kubernetes CSI development team maintains the external-snapshotter Kubernetes CSI Sidecar Containers. Implement CreateSnapshot, DeleteSnapshot, and, optionally, the ListSnapshots, controller RPCs.įor details, see the CSI spec.Implement the CREATE_DELETE_SNAPSHOT and, optionally, the LIST_SNAPSHOTS controller capabilities.To implement the snapshot feature, a CSI driver MUST: Implementing Snapshot & Restore Functionality in Your CSI Driver For example, this is the documentation location for v1.16.

Creation of new volumes pre-populated with the data from a snapshot via Kubernetes dynamic volume provisioning.Creation and deletion of volume snapshots via Kubernetes native API.Kubernetes CSI currently enables CSI Drivers to expose the following functionality via the Kubernetes API: A snapshot can be used either to provision a new volume (pre-populated with the snapshot data) or to restore the existing volume to a previous state (represented by the snapshot).
