Kubernetes Can we use multiple claims out of a persistent volume

Question

can i use many claims out of a persistent volume? please explain.

Answer 1

The mapping between persistentVolume and persistentVolumeClaim is always one to one. 

Even When you delete the claim, PersistentVolume still remains as we set persistentVolumeReclaimPolicy is set to Retain and It will not be reused by any other claims. 

Below is the spec to create the Persistent Volume.

apiVersion: v1
kind: PersistentVolume
metadata:
name: mypv
spec:
capacity:
storage: 5Gi
volumeMode: Filesystem
accessModes:
- ReadWriteOnce
persistentVolumeReclaimPolicy: Retain
