ceph-csi-rbd

The ceph-csi-rbd chart adds rbd volume support to your cluster.

Install from release repo

Add chart repository to install helm charts from it

helm repo add ceph-csi https://ceph.github.io/csi-charts

Install from local Chart

we need to enter into the directory where all charts are present

cd charts

Note: charts directory is present in root of the ceph-csi project

Install chart

To install the Chart into your Kubernetes cluster

• For helm 2.x

  helm install --namespace "ceph-csi-rbd" --name "ceph-csi-rbd" ceph-csi/ceph-csi-rbd
  

• For helm 3.x

  Create the namespace where Helm should install the components with

  kubectl create namespace "ceph-csi-rbd"
  

  Run the installation

  helm install --namespace "ceph-csi-rbd" "ceph-csi-rbd" ceph-csi/ceph-csi-rbd
  

After installation succeeds, you can get a status of Chart

helm status "ceph-csi-rbd"

Delete Chart

If you want to delete your Chart, use this command

• For helm 2.x

  helm delete --purge "ceph-csi-rbd"
  

• For helm 3.x

  helm uninstall "ceph-csi-rbd" --namespace "ceph-csi-rbd"
  

If you want to delete the namespace, use this command

kubectl delete namespace ceph-csi-rbd
