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 --namespace "ceph-csi-rbd" "ceph-csi-rbd"

Upgrade Chart

If you want to upgrade your Chart, use the following commands.

helm repo update ceph-csi
helm upgrade --namespace ceph-csi-rbd ceph-csi-rbd ceph-csi/ceph-csi-rbd

For upgrading to a specific version, provide the flag --version and the version.

Do not forget to include your values, if they differ from the default values. We recommend not to use --reuse-values in case there are new defaults AND compare your currently used values with the new default values.

Known Issues Upgrading

  • When upgrading to version >=3.7.0, you might encounter an error that the RBD CSI Driver cannot be updated. Please refer to issue for more details. This is due to the CSIDriver resource not being updatable. To work around this you can delete the CSIDriver object by running:

    kubectl delete csidriver rbd.csi.ceph.com
    

    Then rerun your helm upgrade command.

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
