title: Kubernetes: how to set VolumeMount user group and file permissions
body: <p>I'm running a Kubernetes cluster on AWS using kops. I've mounted an EBS volume onto a container and it is visible from my application but it's read only because my application does not run as root. How can I mount a <code>PersistentVolumeClaim</code> as a user other than root? The <code>VolumeMount</code> does not seem to have any options to control the user, group or file permissions of the mounted path.</p>
  
  <p>Here is my Deployment yaml file:</p>
  
  <pre><code>apiVersion: extensions/v1beta1
  kind: Deployment
  metadata:
    name: notebook-1
  spec:
    replicas: 1
    template:
      metadata:
        labels:
          app: notebook-1
      spec:
        volumes:
        - name: notebook-1
          persistentVolumeClaim:
            claimName: notebook-1
        containers:
        - name: notebook-1
          image: jupyter/base-notebook
          ports:
          - containerPort: 8888
          volumeMounts:
          - mountPath: "/home/jovyan/work"
            name: notebook-1
  </code></pre>
