# 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 --namespace "ceph-csi-rbd" "ceph-csi-rbd" ``` ### Upgrade Chart If you want to upgrade your Chart, use the following commands. ```bash 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](https://github.com/ceph/ceph-csi/issues/3397) 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: ```bash 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 ```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.
