Breaking Changes
- Flex driver is fully deprecated. If you are still using flex volumes, before upgrading to v1.8 you will need to convert them to csi volumes. See the flex conversion tool.
- Min supported version of K8s is now 1.16. If running on an older version of K8s it is recommended to update to a newer version before updating to Rook v1.8.
- Directory structure of the YAML examples has changed. Files are now in
deploy/examplesand subdirectories.
Ceph
Features

- Rook adds a finalizer
ceph.rook.io/disaster-protectionto resources critical to the Ceph cluster (rook-ceph-mon secrets and configmap) so that the resources will not be accidentally deleted. - Add support for Kubernetes Authentication when using HashiCorp Vault Key Management Service.
- Bucket notification supported via CRDs
- The failure domain of a pool can be changed on the CephBlockPool instead of requiring toolbox commands
- The Rook Operator and the toolbox now run under the "rook" user and does not use "root" anymore.
