The Kubernetes package manager

Common actions for Helm:

- helm search: search for charts
- helm pull: download a chart to your local directory to view
- helm install: upload the chart to Kubernetes
- helm list: list releases of charts

Add rook repo

helm repo add rook-release https://charts.rook.io/release

Install rook-ceph cluster and ceph tools via helm

[root@k8s-10-6-162-31 ~]# helm install --namespace rook-ceph rook-ceph-cluster rook-release/rook-ceph-cluster --set operatorNamespace=rook-ceph --set cephClusterSpec.storage.deviceFilter="^sd." --set cephClusterSpec.cephVersion.image=quay.io/ceph/ceph:v17.2.3
NAME: rook-ceph-cluster
LAST DEPLOYED: Mon Nov 7 14:49:28 2022
NAMESPACE: rook-ceph
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
The Ceph Cluster has been installed. Check its status by running:
kubectl --namespace rook-ceph get cephcluster

Visit https://rook.io/docs/rook/latest/CRDs/ceph-cluster-crd/ for more information about the Ceph CRD.

Important Notes:
- You can only deploy a single cluster per namespace
- If you wish to delete this cluster and start fresh, you will also have to wipe the OSD disks using `sfdisk`
