Create the persistentVolume in file named pv.yaml :

apiVersion: v1
kind: PersistentVolume
metadata:
  name: strawberry-pv
spec:
  capacity:
    storage: 2Gi
  accessModes:
    - ReadWriteOnce
  storageClassName: exam
  hostPath:
    path: /Data/Berry

Apply that file

kubectl create -f pv.yaml

Create the pvc yaml file

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: strawberry-pvc
  namespace: straw
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: exam

and apply that file

kubectl create -f pvc.yaml

Create deployment:

apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    app: strawberry-deploy
  name: strawberry-deploy
  namespace: straw
spec:
  replicas: 1
  selector:
    matchLabels:
      app: strawberry-deploy
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: strawberry-deploy
    spec:
      volumes:
        - name: strawberry-pv
          persistentVolumeClaim:
            claimName: strawberry-pvc
      containers:
      - image: nginx:1.7.9
        name: nginx
        volumeMounts:
          - mountPath: "/tmp/berry-data"
            name: strawberry-pv

Check that the strawberry pv is bound, the pvc is binded and the pod is running:

kubectl get pv strawberry-pv
NAME            CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS   CLAIM                  STORAGECLASS   REASON   AGE

kubectl get pvc -n straw

strawberry-pvc   Pending                                      exam           14m


kubectl get pods -n straw
