# Major Themes
|
|
|
|
## Action Required
|
|
|
|
## 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](Documentation/ceph-nfs-crd.md).
|
|
- Selinux labeling for mounts can now be toggled with the [ROOK_ENABLE_SELINUX_RELABELING](https://github.com/rook/rook/issues/2417) environment variable.
|
|
- Recursive chown for mounts can now be toggled with the [ROOK_ENABLE_FSGROUP](https://github.com/rook/rook/issues/2254) 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.
|
|
- The number of mons can be increased automatically when new nodes come online. See the [preferredCount](https://rook.io/docs/rook/master/ceph-cluster-crd.html#mon-settings) setting in the cluster CRD documentation.
|
|
- 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](https://github.com/rook/rook/issues/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
|
|
|
|
- The example operator and CRD yaml files have been refactored to simplify configuration. See the [examples help topic](Documentation/ceph-examples.md) for more details.
|
|
- The common resources are now factored into `common.yaml` from `operator.yaml` and `cluster.yaml`.
|
|
- `common.yaml`: Creates the namespace, RBAC, CRD definitions, and other common operator and cluster resources
|
|
- `operator.yaml`: Only contains the operator deployment
|
|
- `cluster.yaml`: Only contains the cluster CRD
|
|
- Multiple examples of the operator and CRDs are provided for common usage of the operator and CRDs.
|
|
- By default, a single namespace (`rook-ceph`) is configured instead of two namespaces (`rook-ceph-system` and `rook-ceph`). New and upgraded clusters can still be configured with the operator and cluster in two separate namespaces.
|
|
- 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.
