Rook (Ceph) - In Cluster

Deploy the Rook operator

kubectl apply -k /etc/genestack/kustomize/rook-operator/
kubectl -n rook-ceph set image deploy/rook-ceph-operator rook-ceph-operator=rook/ceph:v1.13.7

Deploy the Rook cluster

Note

Rook will deploy against nodes labeled role=storage-node. Make sure to have a look at the /etc/genestack/kustomize/rook-cluster/rook-cluster.yaml file to ensure it's setup to your liking, pay special attention to your deviceFilter settings, especially if different devices have different device layouts.

kubectl apply -k /etc/genestack/kustomize/rook-cluster/

Validate the cluster is operational

kubectl --namespace rook-ceph get cephclusters.ceph.rook.io

Note

You can track the deployment with the following command kubectl --namespace rook-ceph get pods -w.

Create Storage Classes

Once the rook cluster is online with a HEALTH status of HEALTH_OK, deploy the filesystem, storage-class, and pool defaults.

kubectl apply -k /etc/genestack/kustomize/rook-defaults

Note

If installing prometheus after rook-ceph is installed, you may patch a running rook-ceph cluster with the following command.

kubectl -n rook-ceph patch CephCluster rook-ceph  --type=merge -p "{\"spec\": {\"monitoring\": {\"enabled\": true}}}"

Ensure you have 'servicemonitors' defined in the rook-ceph namespace.
