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
