Creating Persistent Volume in a Kubernetes cluster using NFS

To create a persistent volume you need one NFS mounted directory per server so that it can be accessed from all worker nodes.

To create a Persistent Volume use a yaml file with NFS drive configuration declared.

Sample Volume File

apiVersion: v1
kind: PersistentVolume
metadata:
  name: cc-pv-volume
  labels:
    type: local
    author: ccuser
spec:
  storageClassName: manual
  capacity:
    storage: 2Gi
  accessModes:
    - ReadWriteMany
 # persistentVolumeReclaimPolicy: Retain
  nfs:
    path: /docker_volume/
    server: 111.22.333.444
    readOnly: false

Follow the steps given below to create a Persistent Volume in Kubernetes using NFS:

Change storage path and server parameters in the given sample file based on your deployment configuration and save this file as, cc-pv-volume.yaml inside Kubernetes_scripts.

Invoke the following commands:

$ cd
$ cd Kubernetes_scripts
$ vi cc-pv-volume.yaml

Copy the file content from the sample file given above into this file and save it.
```
$ kubectl create -f cc-pv-volume.yaml
```
Invoke the following command to verify if your Persistence Volume is created:
```
$ kubectl get pv
```
