I am a bit confused here. It does work as normal docker container but when it goes inside a pod it doesnt. So here is how i do it.

Dockerfile in my local to create the image and publish to docker registry

FROM alpine:3.7
COPY . /var/www/html
CMD tail -f /dev/null

Now if i just pull the image(after deleting the local) and run as a container. It works and i can see my files inside /var/www/html.

Now i want to use that inside my kubernetes cluster.

Def : Minikube --vm-driver=none

I am running kube inside minikube with driver none option. So for single node cluster.

EDIT

I can see my data inside /var/www/html if i remove volume mounts and claim from deployment file.

Deployment file

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  labels:
    io.kompose.service: app
  name: app
spec:
  replicas: 1
  strategy:
    type: Recreate

    metadata:
      creationTimestamp: null
      labels:
        io.kompose.service: app
    spec:

        runAsGroup: 1000
      containers:

        name: pd-mycode
        resources: {}
        volumeMounts:
        - mountPath: /var/www/html
          name: claim-app-storage
      restartPolicy: Always
      volumes:
      - name: claim-app-storage
        persistentVolumeClaim:
          claimName: claim-app-nginx
status: {}

PVC file

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  creationTimestamp: null
  labels:
    io.kompose.service: app-nginx1
  name: claim-app-nginx
spec:
  storageClassName: testmanual
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 100Mi
status: {}

PV file

apiVersion: v1
kind: PersistentVolume
metadata:
  name: app-nginx1
  labels:
    type: local
spec:
  storageClassName: testmanual
  capacity:
    storage: 100Mi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/data/volumes/app"

Now when i run these files it creates the pod, pv, pvc and pvc is bound to pv. But if i go inside my container i dont see my files. hostpath is /data/volumes/app . Any ideas will be appreciated.
