# 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
```
