v4.0.0 - 2026.03.30

⚠️ See the update instructions.

Breaking change: This release requires Kubernetes VolumeSnapshot CRDs and the external snapshot controller to be installed before installing or upgrading this driver. Clusters without these components must install them first. Otherwise, snapshot-related operations and the snapshot resource in the Helm chart will fail to work.

  • Add CSI snapshot support, including create, delete, list, and creating volumes from snapshots.
  • Add VolumeSnapshotClass and other snapshot-related resources to the Helm chart and examples. When using Helm, snapshot classes are now created from the csi.snapshotClasses configuration.
  • Cleaned up RBAC rules in Helm chart.
  • Prevent silent volume migration in ControllerPublishVolume.
  • Update github.com/cloudscale-ch/cloudscale-go-sdk fron v6.0.1 to v7.0.0.
  • Bump github.com/sirupsen/logrus from v1.9.3 to v1.9.4.
  • Bump google.golang.org/grpc from v1.77.0 to v1.79.3.
  • Bump golang.org/x/sys from v0.39.0 to v0.42.0.
  • Bump golang.org/x/oauth2 from v0.35.0 to v0.36.0.

v3.6.1 - 2026.03.27

  • Backport for 3.6.x: Prevent silent volume migration in ControllerPublishVolume.

v3.6.0 - 2026.01.15

⚠️ Update 2026.02.04: Breaking Change
We regret to inform you that this release includes a refactoring that drops support for cluster nodes using virtio-blk. Unfortunately, this effect was missed during our review and only discovered post-release.

If your cluster contains nodes provisioned before October 1st, 2020, or in some customer-specific setups before mid-2021, we recommend checking the output of lsblk to ensure that your nodes are not affected. If the output of lsblk contains volume names in the form vdX, you are still using virtio-blk and should not update to this release. In this case, we recommend to either provision new nodes (that will automatically use virtio-scsi) or pin to v3.5.6.

Important

This release contains breaking changes, because of the update to the CSI spec v1.0.0 and the introduction of the csi.cloudscale.ch/volume-type parameter.

Your kubernetes version must be at least v1.13.0 to support CSI spec v1.0.0.

If you have deployed previous versions of the CSI plugin, you cannot update the existing cloudscale-volume-ssd storage class, because parameters of a storage class cannot be changed. However, the default behaviour of the CSI plugin is to use volumes of type ssd unless specified otherwise, so you can just leave the cloudscale-volume-ssd storage class as it is.

Make sure you have the following feature gates activated:

  • CSINodeInfo=true
  • CSIDriverRegistry=true

The following features are required but are GA in kubernetes v1.13.0. No explicit feature gate activation is needed:

  • CSIPersistentVolume=true
  • MountPropagation=true
  • KubeletPluginsWatcher=true

v0.2.0 - 2018.09.05

  • Add support to CSI Spec v0.3.0. This includes many new changes, make sure to read the Github PR for more information [GH-72]
  • Check volume limits before provisioning calls [GH-73]
  • Rename resource (DaemonSet, StatefulSet, containers, etc..) names and combine the attacher and provisioner into a single Statefulset. [GH-74]

IMPORTANT:This release contains breaking changes, mainly about how thing are deployed. The minimum Kubernetes version needs to be now v1.10.5. To upgrade from a prior v0.1.x versions please remove the old CSI plugin completely and re-install the new one:

# delete old version, i.e: v0.1.5
kubectl delete -f https://raw.githubusercontent.com/cloudscale-ch/csi-cloudscale/master/deploy/kubernetes/releases/csi-cloudscale-v0.1.5.yaml

# install v0.2.0
kubectl apply -f https://raw.githubusercontent.com/cloudscale-ch/csi-cloudscale/master/deploy/kubernetes/releases/csi-cloudscale-v0.2.0.yaml

v0.1.5 - 2018.08.27

  • Makefile improvements. Please check the GH link for more information. [GH-66]
  • Validate volume capabilities during volume creation. [GH-68]
  • Add version information to logs [GH-65]

v0.1.4 - 2018.08.23

  • Add logs to mount operations [GH-55]
  • Remove description to allow users to reuse volumes that were created by the UI/API [GH-59]
  • Handle edge cases from external action, such as Volume deletion via UI more gracefully. We're not very strict anymore in cases we don't need to be, but we're also returning a better error in cases we need to be. [GH-60]
  • Fix attaching multiple volumes to a single pod [GH-61]

v0.1.3 - 2018.08.03

  • Fix passing an empty source to IsMounted() function during NodeUnpublish. This would prevent a pod to be deleted successfully in case of a dettached volume, because NodeUnpublish would never return success as IsMounted() was failing. [GH-50]

v0.1.2 - 2018.08.02

  • Check if mounts are propagated (MountPropagation is enabled on the host) in Node plugin to prevent silent failing. [GH-46]
  • Fix IsMounted() for bind mounts where it was returning false positives. [GH-46]
  • Log 422 errors for visibility in Controller publish/unpublish methods. [GH-38]

v0.1.1 (alpha) - 2018.05.29

  • Fix panicking on errors for nil response objects [GH-34]

v0.1.0 (alpha) - 2018.05.15

  • Add method names to each log entry [GH-22]
  • Kubernetes deployment uses the kube-system namespace instead of the prior default namespace. Please make sure to delete and re-deploy the plugin. [GH-21]
  • Change secret name from dotoken to digitalocean. Please make sure to update your keys (delete old secret and create new secret with name digitalocean). Checkout the README for instructions if needed. [GH-21]
  • Make DigitalOcean API configurable via the new --url flag [GH-27]

v0.0.1 (alpha) - 2018.05.10

  • First release with all important methods of the CSI spec implemented
