# ⚠️ Repo Archive Notice
As of Nov 13, 2020, charts in this repo will no longer be updated.
For more information, see the Helm Charts [Deprecation and Archive Notice](https://github.com/helm/charts#%EF%B8%8F-deprecation-and-archive-notice), and [Update](https://helm.sh/blog/charts-repo-deprecation/).
# nfs-client-provisioner
The [NFS client provisioner](https://github.com/kubernetes-incubator/external-storage/tree/master/nfs-client) is an automatic provisioner for Kubernetes that uses your *already configured* NFS server, automatically creating Persistent Volumes.
## DEPRECATION NOTICE
This chart is deprecated and no longer supported.
## TL;DR;
```console
$ helm install --set nfs.server=x.x.x.x --set nfs.path=/exported/path stable/nfs-client-provisioner
```
For **arm** deployments set `image.repository` to `--set image.repository=quay.io/external_storage/nfs-client-provisioner-arm`
## Introduction
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-incubator/external-storage/tree/master/nfs-client) 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`:
```console
$ helm install --name my-release --set nfs.server=x.x.x.x --set nfs.path=/exported/path stable/nfs-client-provisioner
```
The command deploys the given storage class in the default configuration. It can be used afterswards 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.
## Configuration
The following tables lists the configurable parameters of this chart and their default values.
| Parameter | Description | Default |
| ----------------------------------- | ----------------------------------------------------------- | ------------------------------------------------- |

| `resources` | Resources required (e.g. CPU, memory) | `{}` |
| `rbac.create` | Use Role-based Access Control | `true` |
| `podSecurityPolicy.enabled` | Create & use Pod Security Policy resources | `false` |
| `priorityClassName` | Set pod priorityClassName | null |
