<p>I have pod (kind:job) which is having some code build files under "/usr/src/app" and these files I need in my local k8s host.</p>

<p>But when I am trying to do as per below yamls, I am not able to see any data in mounted host path which is actually exists in pod container ("/usr/src/app"). I think mounting is overwriting/hide that data. Please help me to get in my local k8s host.</p>

<p>My files are :-</p>

<pre><code>apiVersion: batch/v1
kind: Job
metadata:
  name: wf
spec:
  template:
    spec:
      containers:
      - name: wf

        volumeMounts:
          - name: wf-persistent-storage
            mountPath: /usr/src/app    # my data is in (/usr/src/app)
      volumes:
        - name: wf-persistent-storage
          # pointer to the configuration of HOW we want the mount to be implemented
          persistentVolumeClaim:
            claimName: wf-test-pvc
      restartPolicy: Never

<p>Don't mount your /usr/src/app. As it will get overwritten by the contents of the PVC. In your case the pvc is empty initially so all the files will be deleted.</p>

<p>Try with the below code, where you will be mounting /tmp on the pvc and using command the files will be copied to the pvc.</p>

<pre><code>apiVersion: batch/v1
kind: Job
metadata:
  name: wf
spec:
  template:
    spec:
      containers:
      - name: wf
        image: 12345678.dkr.ecr.ap-south-1.amazonaws.com/eks:ws
        command:
        - bash 
        - -c
        - cp -R /usr/src/app/* /tmp/ 
        volumeMounts:
          - name: wf-persistent-storage
            mountPath: /opt    # my data is in (/usr/src/app)
      volumes:
        - name: wf-persistent-storage
          # pointer to the configuration of HOW we want the mount to be implemented
          persistentVolumeClaim:
            claimName: wf-test-pvc
      restartPolicy: Never
</code></pre>
