Notable Features

Minio Object Stores

- Now have an additional label named `objectstore` with the name of the Object Store, to allow better selection for Services.
- Use `Readiness` and `Liveness` probes.
- Updated automatically on Object Store CRD changes.

Ceph

  • A CephNFS CRD will start NFS daemon(s) for exporting CephFS volumes or RGW buckets. See the NFS documentation.
  • Selinux labeling for mounts can now be toggled with the ROOK_ENABLE_SELINUX_RELABELING environment variable.
  • Recursive chown for mounts can now be toggled with the ROOK_ENABLE_FSGROUP environment variable.
  • Added the dashboard port configuration setting.
  • Added the dashboard ssl configuration setting.
  • Added Ceph CSI driver deployments on Kubernetes 1.13 and above.
  • New Kubernetes nodes or nodes which are not tainted NoSchedule anymore get added automatically to the existing rook cluster if useAllNodes is set. Issue #2208

Breaking Changes

  • Rook no longer supports Kubernetes 1.8 and 1.9.
  • Rook no longer supports running more than one monitor on the same node when hostNetwork and allowMultiplePerNode are true.
  • Rook Operator switches from Extensions v1beta1 to use Apps v1 API for DaemonSet and Deployment.

Ceph

  • Rook will no longer create a directory-based osd in the dataDirHostPath if no directories or devices are specified or if there are no disks on the host.
  • Containers in mon, mgr, mds, rgw, and rbd-mirror pods have been removed and/or changed names.
  • Config paths in mon, mgr, mds and rgw containers are now always under /etc/ceph or /var/lib/ceph and as close to Ceph's default path as possible regardless of the dataDirHostPath setting.
  • The rbd-mirror pod labels now read rbd-mirror instead of rbdmirror for consistency.
