description:nfs-subdir-external-provisioner is an automatic provisioner that used your *already configured* NFS server, automatically creating Persistent Volumes.
The [NFS subdir external provisioner](https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner) is an automatic provisioner for Kubernetes that uses your *already configured* NFS server, automatically creating Persistent Volumes.
This charts installs custom [storage class](https://kubernetes.io/docs/concepts/storage/storage-classes/) into a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager. It also installs a [NFS client provisioner](https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner) into the cluster which dynamically creates persistent volumes from single NFS share.
## Prerequisites
- Kubernetes >=1.9
- Existing NFS Share
## Installing the Chart
To install the chart with the release name `my-release`:
The command deploys the given storage class in the default configuration. It can be used afterwards to provision persistent volumes. The [configuration](#configuration) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```console
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.

## Install Multiple Provisioners
It is possible to install more than one provisioner in your cluster to have access to multiple nfs servers and/or multiple exports from a single nfs server. Each provisioner must have a different `storageClass.provisionerName` and a different `storageClass.name`. For example:
