# 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 ```console 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 ```console 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 ```bash 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 ```bash kubectl create namespace "ceph-csi-rbd" ``` Run the installation ```bash helm install --namespace "ceph-csi-rbd" "ceph-csi-rbd" ceph-csi/ceph-csi-rbd ``` After installation succeeds, you can get a status of Chart ```bash helm status "ceph-csi-rbd" ``` ### Delete Chart If you want to delete your Chart, use this command - For helm 2.x ```bash helm delete --purge "ceph-csi-rbd" ``` - For helm 3.x ```bash helm uninstall "ceph-csi-rbd" --namespace "ceph-csi-rbd" ``` If you want to delete the namespace, use this command ```bash kubectl delete namespace ceph-csi-rbd ``` ### Configuration The following table lists the configurable parameters of the ceph-csi-cephfs charts and their default values. | Parameter | Description | Default | | ---------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------- | | `rbac.create` | Specifies whether RBAC resources should be created | `true` | | `serviceAccounts.nodeplugin.create` | Specifies whether a nodeplugin ServiceAccount should be created | `true` | | `serviceAccounts.nodeplugin.name` | The name of the nodeplugin ServiceAccount to use.
