CephClusterConnection configuration

The CephClusterConnection resource defines the connection parameters to your Ceph cluster. This resource must be created before creating CephStorageClass objects.

Example configuration:

apiVersion: storage.deckhouse.io/v1alpha1
kind: CephClusterConnection
metadata:
  name: ceph-cluster-1
spec:
  clusterID: 014df517-39d1-4453-b7b3-9930c563627c
  monitors:
  - 172.20.1.28:6789
  - 172.20.1.34:6789
  - 172.20.1.37:6789
  userID: admin
  userKey: <your-ceph-auth-key>

To verify the creation of the object, use the following command (Phase should be Created):

d8 k get cephclusterconnection <cephclusterconnection name>

CephStorageClass configuration

The CephStorageClass resource defines StorageClass parameters for provisioning persistent volumes. You can create different storage classes for RBD and CephFS storage types.

RBD

Example of a StorageClass configuration for RBD (RADOS Block Device) volumes:

apiVersion: storage.deckhouse.io/v1alpha1
kind: CephStorageClass
metadata:
  name: ceph-rbd-sc
spec:
  clusterConnectionName: ceph-cluster-1
  reclaimPolicy: Delete
  type: RBD
  rbd:
    defaultFSType: ext4
    pool: ceph-rbd-pool

CephFS

Example of a StorageClass configuration for CephFS (Ceph File System) volumes:

apiVersion: storage.deckhouse.io/v1alpha1
kind: CephStorageClass
metadata:
  name: ceph-fs-sc
spec:
  clusterConnectionName: ceph-cluster-1
  reclaimPolicy: Delete
  type: CephFS
  cephFS:
    fsName: cephfs

To verify the creation of the object, use the following command (Phase should be Created):

d8 k get cephstorageclass <cephstorageclass name>
