v5.0.1

Overall Status

Volume snapshotting has been a GA feature since Kubernetes v1.20.

Supported CSI Spec Versions

1.0-1.5

Minimum Kubernetes version

1.20

Recommended Kubernetes version

1.20+

Container

docker pull registry.k8s.io/sig-storage/snapshot-controller:v5.0.1
docker pull registry.k8s.io/sig-storage/csi-snapshotter:v5.0.1
docker pull registry.k8s.io/sig-storage/snapshot-validation-webhook:v5.0.1

Notable Changes in v5.0.1 compared to v5.0.0

• Update release tools and pull in the change to increase the timeout value to allow all snapshot images to be build before the timeout. (#641, @xing-yang)

Breaking Changes

• Replaces many VolumeSnapshot/VolumeSnapshotContent Update/UpdateStatus operations with Patch. This lowers the probability of the "object has been modified" update API errors occurring. This change introduces a dependency on two new RBAC rules for the CSI snapshotter sidecar: volumesnapshotcontents:patch, volumesnapshotcontents/status:patch and four new RBAC rules for the snapshot-controller: volumesnapshotcontents:patch, volumesnapshotcontents/status:patch, volumesnapshots:patch, and volumesnapshots/status: patch. (#526, @ggriffiths)

Feature

• Added short names for Volume Snapshot CRDs:
  • VolumeSnapshot - vs
  • VolumeSnapshotContent - vsc, vscs
  • VolumeSnapshotClass` - vsclass, vsclasses (#604, @robbie-demuth)
• Adds support for distributed snapshotting. This affects both snapshot controller and CSI snapshotter sidecar. (#585, @nearora-msft)
• Make the QPS and Burst of kube client config to be configurable in both snapshot-controller and CSI snapshotter sidecar (#621, @lintongj)

Design

• Added kustomization manifests to CRDs, snapshot controller, and CSI snapshotter sidecar components (#606, @itspngu)

Bug or Regression

• Fixed a bug introduced by #621 which makes the QPS and Burst of kube client config configurable in both snapshot-controller and CSI snapshotter sidecar. This fix exposed the kube-api-qps cmd option properly (#626, @lintongj)
• Fixed deadlock in reporting metrics in snapshot controller. (#581, @jsafrane)
• Replaces many VolumeSnapshot/VolumeSnapshotContent Update/UpdateStatus operations with Patch. This lowers the probability of the "object has been modified" update API errors occurring. This change introduces a dependency on two new RBAC rules for the CSI snapshotter sidecar: volumesnapshotcontents:patch, volumesnapshotcontents/status:patch and four new RBAC rules for the snapshot-controller: volumesnapshotcontents:patch, volumesnapshotcontents/status:patch, volumesnapshots:patch, and volumesnapshots/status: patch. (#526, @ggriffiths)

Other (Cleanup or Flake)

• Rename KUBE_NODE_NAME to NODE_NAME for CSI snapshotter sidecar deployment. (#616, @zhucan)

Uncategorized

• Updated CertificateSigningRequest apiversion to V1 for Snapshot validation webhook deployment. (#588, @Kartik494)

Feature

Snapshot APIs

• The namespace of the referenced VolumeSnapshot is printed when printing a VolumeSnapshotContent. (#535, @tsmetana)

Snapshot Controller

• retry-interval-start and retry-interval-max arguments are added to common-controller which controls retry interval of failed volume snapshot creation and deletion. These values set the ratelimiter for snapshot and content queues. (#530, @humblec)
• Add command line arguments leader-election-lease-duration, leader-election-renew-deadline, and leader-election-retry-period to configure leader election options for the snapshot controller. (#575, @bertinatto)
• Adds an operations_in_flight metric for determining the number of snapshot operations in progress. (#519, @ggriffiths)
• Introduced "SnapshotCreated" and "SnapshotReady" events. (#540, @rexagod)

CSI Snapshotter Sidecar

• retry-interval-start and retry-interval-max arguments are added to csi-snapshotter sidecar which controls retry interval of failed volume snapshot creation and deletion. These values set the ratelimiter for volumesnapshotcontent queue. (#308, @humblec)
• Add command line arguments leader-election-lease-duration, leader-election-renew-deadline, and leader-election-retry-period to configure leader election options for CSI snapshotter sidecar. (#538, @RaunakShah)
