v1.2.0

Breaking Changes

• Changes the API group name for the fake VolumeSnapshot object to "snapshot.storage.k8s.io" to be in-sync with the group name of the real VolumeSnapshot object. As a result, the generated interfaces for clientset and informers of VolumeSnapshot are also changed from "VolumeSnapshot" to "Snapshot". (#123, @xing-yang)

New Features

• Adds Finalizer on the snapshot source PVC to prevent it from being deleted when a snapshot is being created from it. (#47, @xing-yang)

Other Notable Changes

• Add Status subresource for VolumeSnapshot. (#121, @zhucan)

Release v1.0.1

Overall Status

Supported CSI Spec Versions

1.0.0

Breaking Changes

c422fbd Switch to use TypedLocalObjectReference in core API.
92f87c1 Update csi/v0 import to csi/.
9be7a7d Update vendor csi spec and csi-test to 1.0.0-rc2.
83c8c05 Update snapshotter to use CSI spec 1.0.
c01fb64 Call CreateSnapshot to check if snapshot is processed instead of ListSnapshots.
e2f1bdc Bumping k8s version to 1.13.0-beta.1.
bfba4cb Rename Ready to ReadyToUse in the Status field of VolumeSnapshot API object.

Actions Required

• CSI plugin must support the 1.0 spec. CSI spec versions < 1.0 are no longer supported.

  • In CSI v1.0, SnapshotStatus is removed from CreateSnapshotResponse, and is replaced with a Boolean ReadyToUse.
  • The snapshot controller now calls CreateSnapshot instead of ListSnapshots to check if snapshot is processed after it is cut. Driver maintainer needs to make changes accordingly in the driver.
  • In CSI v1.0, .google.protobuf.Timestamp is used instead of int64 to represent the creation time of a snapshot. Driver maintainer needs to make changes accordingly in the driver. The creation time is visible to the admin when running kubectl describe volumesnapshotcontent to examine the details of a VolumeSnapshotContent.

• The renaming from Ready to ReadyToUse in the Status field of VolumeSnapshot API object is visible to the user when running kubectl describe volumesnapshot to view the details of a snapshot.

• External-provisioner sidecar container which depends on external-snapshotter APIs needs to be updated whenever there is an API change in external-snapshotter. Compatible sidecar container images for external-provisioner and external-snapshotter need to be used together, i.e., both are v1.0.0 or both are v1.0.1.

Deprecations

• The following VolumeSnapshotClass parameters are deprecated and will be removed in a future release:

Deprecated	Replacement
csiSnapshotterSecretName	csi.storage.k8s.io/snapshotter-secret-name
csiSnapshotterSecretNameSpace	csi.storage.k8s.io/snapshotter-secret-namespace
