  • Added leader election health check at the metrics port + path "/healthz/leader-election".
    • metrics-address flag is deprecated and replaced by http-endpoint, which enables handlers from both metrics manager and leader election health check. (#439, @xing-yang)

Snapshot Controller

  • The http-endpoint and metrics-path flags have been added to support metrics for the snapshot-controller. (#409, @ggriffiths)

Bug or Regression

Snapshot Controller

  • Bug fix to allow creation of snapshot content if pvc finalizer exists, even if pvc is marked for deletion. (#413, @RaunakShah)

Validation Webhook

  • The validation-webhook server will now watch for changes to --tls-cert-file and --tls-private-key-file and update the server's TLS config accordingly. (#429, @ggriffiths)

Other (Cleanup or Flake)

  • Increased the default re-sync period to 15 minutes for the snapshotter sidecar and snapshot controller. (#447, @ggriffiths)

Breaking Changes

  • Update volume snapshot APIs and client library to v3. Volume snapshot APIs and client library are in a separate sub-module: github.com/kubernetes-csi/external-snapshotter/client/v3. (#373, @xing-yang)

  • Added Go Module for APIs and Client. Volume snapshot APIs and client library are now in a separate sub-module. (#307, @Kartik494)

  • With kubernetes 1.18 release of client-go, signatures on methods in generated clientsets, dynamic, metadata, and scale clients have been modified to accept context.Context as a first argument. Signatures of Create, Update, and Patch methods have been updated to accept CreateOptions, UpdateOptions and PatchOptions respectively. Signatures of Delete and DeleteCollection methods now accept DeleteOptions by value instead of by reference. These changes are now accommodated with this PR and client-go and dependencies are updated to v1.18.0 (#286, @humblec)

New Features

  • The validation for volume snapshot objects (VolumeSnapshot and VolumeSnapshotContent) is getting more strict. Due to backwards compatibility this change will occur over multiple releases. The following key changes are highlighted.

    1. As part of the first phase of the multi-phased release process, a validating
      webhook server has been added. This server will perform additional validation (strict) which was not done during the beta release of volume snapshots. It will prevent the cluster from gaining (via create or update) invalid objects.
    2. The controller will label objects which fail the additional validation. The label "snapshot.storage.kubernetes.io/invalid-snapshot-content-resource" will be added to invalid VolumeSnapshotContent objects. The label "snapshot.storage.kubernetes.io/invalid-snapshot-resource" will be added to invalide VolumeSnapshot objects.

    The combination of 1 and 2 will allow cluster admins to stop the increase of invalid objects, and provide a way to easily list all objects which currently fail the strict validation. It is the kubernets distribution and cluster admin's responsibility to install the webhook and to ensure all the invalid objects in the cluster have been deleted or fixed. See the KEP at https://github.com/kubernetes/enhancements/blob/master/keps/sig-storage/177-volume-snapshot/tighten-validation-webhook-crd.md (#353, @AndiLi99)

Snapshot Controller

  • With the addition of the validating webhook server, the snapshot controller is modified to label objects which fail the additional validation. The label "snapshot.storage.kubernetes.io/invalid-snapshot-content-resource" will be added to invalid VolumeSnapshotContent objects. The label "snapshot.storage.kubernetes.io/invalid-snapshot-resource" will be added to invalide VolumeSnapshot objects. (#353, @AndiLi99)
  • Snapshot APIs and Client are now in a separate go package. The snapshot controller is modified to use the new package. (#307, @Kartik494)

CSI External-Snapshotter Sidecar

  • Snapshot APIs and Client are now in a separate go package. The CSI external-snapshotter sidecar is modified to use the new package. (#307, @Kartik494)
