# 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.

The following tables lists the configurable parameters of this chart and their default values.
