🔹 Kubernetes - Kubernetes v1.34: Moving Volume Group Snapshots to v1beta2

The blog post discusses the update of Kubernetes to version 1.34, which includes moving the Volume Group Snapshots feature to version v1beta2. Initially introduced as an Alpha feature in Kubernetes 1.27 and moved to Beta in 1.32, Volume Group Snapshots allow users to take crash-consistent snapshots of a set of volumes using extension APIs for group snapshots. This feature is only supported for CSI volume drivers. A new issue was identified during testing, leading to changes in the API and the release of a new beta version. The v1beta2 introduces a new VolumeSnapshotInfo struct and VolumeSnapshotInfoList to better handle snapshot information. Existing API objects will be converted to the new format using a conversion webhook. The post also mentions plans to move this feature to general availability (GA) in the future, depending on feedback and adoption. It provides links to further resources and acknowledges the contributors involved in the development. The blog encourages interested individuals to join the Kubernetes Storage Special Interest Group (SIG) or the Data Protection Working Group to get involved in the project’s development. 👉 Read more
