title: How to create an kubernetes NFS volume on Google Container Engine
body: <p>I am trying to create a kubernetes NFS volume on Google Container Engine (GKE) and get it used by a deployment.</p>
  
  <p>I did this in several steps as it shown in this github repository <a href="https://github.com/mappedinn/kubernetes-nfs-volume-on-gke" rel="nofollow noreferrer">kubernetes-nfs-volume-on-gke</a>:</p>
  
  <ol>
  <li>Create a GKE cluster and GCE persistent disk</li>
  <li>Config the context for the kubectl to deal with the GKE cluster</li>
  <li>Creation of the PersistentVolume (PV) and the PersistentVolumeClaim (PVC)</li>
  <li>Creation of an NFS server</li>
  <li>Create a service for the NFS server to expose it (the IP address of that service is used for the creation of the NFS PV and NFS PVC)</li>
  <li>Creation of NFS volume</li>
  <li>Create a Deployment of a busybox for checking the NFS volume is accessible.</li>
  </ol>
  
  <p>After fellowing these step, this is the obtained error:</p>
