# NFS Client Provisioner
[NFS Client Provisioner](https://github.com/kubernetes-incubator/external-storage/tree/master/nfs-client)
is an automatic provisioner that uses your already configured NFS server to automatically create Persistent Volumes.
## TL;DR;
```console
$ helm install rimusz/nfs-client-provisioner --set nfs.server="1.2.3.4"
```
## Introduction
This chart bootstraps a [nfs-client-provisioner](https://github.com/kubernetes-incubator/external-storage/tree/master/nfs-client)
deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh)
package manager.
## Installing the Chart
To install the chart with the release name `nfs`:
```console
$ helm install rimusz/nfs-client-provisioner --name nfs --set nfs.server="1.2.3.4"
```
The command deploys nfs-client-provisioner on the Kubernetes cluster in the default
configuration. The [configuration](#configuration) section lists the parameters
that can be configured during installation.
## Testing the Chart
Now we'll test your NFS provisioner.
Deploy:
```console
$ kubectl create -f test/test-claim.yaml -f test/test-pod.yaml
```
Now check in PVC folder on your NFS Server for the file `SUCCESS`.
Delete:
```console
kubectl delete -f test/test-pod.yaml -f test/test-claim.yaml
```
Now check that PVC folder got renamed to `archived-???`.
## Deploying your own PersistentVolumeClaim
To deploy your own PVC, make sure that you have the correct `storage-class` as indicated by your `values.yaml` file.
For example:
```yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: test-claim
annotations:
volume.beta.kubernetes.io/storage-class: "nfs"
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 5Mi
```
## Uninstalling the Chart
To uninstall/delete the `nfs` deployment:
```console
$ helm delete nfs
```
The command removes all the Kubernetes components associated with the chart and
deletes the release.
## Configuration
The following table lists the configurable parameters of the kibana chart and
their default values.
| Parameter | Description | Default |
|:-------------------------------|:----------------------------------------------------------------------------------|:------------------------------------------------------|
| `image.repository` | The image repository to pull from | `quay.io/kubernetes_incubator/nfs-client-provisioner` |
| `image.tag` | The image tag to pull from | `v2.1.0-k8s1.10` |
| `image.pullPolicy` | Image pull policy | `IfNotPresent` |
| `nfs.server` | NFS server IP | `` |
| `nfs.path` | NFS server share path | `/vol1` |
| `storageClass.create` | Enable creation of a StorageClass to consume this nfs-client-provisioner instance | `true` |
| `storageClass.name` | The name to assign the created StorageClass | `nfs` |
| `storageClass.reclaimPolicy` | Set the reclaimPolicy for PV within StorageClass | `Delete` |
| `rbac.create` | Enable RABC | `false` |
| `rbac.serviceAccountName` | Service account name | `default` |
| `resources` | Resource limits for nfs-client-provisioner pod | `{}` |
| `nodeSelector` | Map of node labels for pod assignment | `{}` |
| `tolerations` | List of node taints to tolerate | `[]` |
| `affinity` | Map of node/pod affinities | `{}` |
```console
$ helm install rimusz/nfs-client-provisioner --name nfs \
--set nfs.server="1.2.3.4",resources.limits.cpu=200m
```
Alternatively, a YAML file that specifies the values for the above parameters
can be provided while installing the chart. For example,
```console
$ helm install rimusz/nfs-client-provisioner --name nfs -f values.yaml
```
> **Tip**: You can use the default [values.yaml](values.yaml) as an example

The NFS Client Provisioner deployment has now been installed.

{{- end }}
{{ if .Values.storageClass.create -}}
A storage class named '{{ .Values.storageClass.name }}' has now been created
and is available to provision dynamic volumes.
You can use this storageclass by creating a `PersistentVolumeClaim` with the
correct storageClassName attribute. For example:
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: test-claim
annotations:
volume.beta.kubernetes.io/storage-class: "{{ .Values.storageClass.name }}"
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 5Mi
{{ else -}}
A storage class has NOT been created. You may create a custom `StorageClass`
resource with a `provisioner` annotation of `{{ template "nfs-client-provisioner.provisionerName" . }}`.
{{ end -}}
