Persistent Storage

Overview

In this article I’ll configure and verify Persistent Storage for the Kubernetes cluster.

Installation

This is a simple installation. The NFS server has 100 gigs of space which will be used for any Persistent Volume Claims (PVCs) needed by application.

Apply the following storage-pv.yaml file.

apiVersion: v1
kind: PersistentVolume
metadata:
  name: storage-pv
spec:
  capacity:
    storage: 100Gi
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  nfs:
    path: /srv/nfs4/storage
    server: 192.168.101.170

Verify by checking the PV in the cluster.

$ kubectl get pv
NAME         CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS      CLAIM   STORAGECLASS   REASON   AGE
storage-pv   100Gi      RWX            Retain           Available                                   7s

And that’s it. Storage is now available for any applications.
