Correct Answer:
See the solution below in Explanation.
Explanation:
Solution:
* Create landing-pv.yaml:
apiVersion: v1
kind: PersistentVolume
metadata:
name: landing-pv
spec:
capacity:
storage: 1Gi
accessModes:
- ReadOnlyMany
nfs:
path: /open001
server: 192.168.2.2
persistentVolumeReclaimPolicy: Retain
* Apply it:
oc apply -f landing-pv.yaml
* Create landing-pvc.yaml:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: landing-pvc
spec:
accessModes:
- ReadOnlyMany
resources:
