Create a volume in kubernetes that won t get destroyed even if the pods die

Question

I have a docker image that when created should check if the volume is empty, in case it should initialize it with some data. This saved data must remain available for other pods with the same or different image.

What do you recommend me to do?

Answer 1

You can use the writemany which should alleviate a deadlock.

apiVersion: v1
kind: PersistentVolume
metadata:
  name: shared-volume
spec:
  capacity:
    storage: 1Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: ""
  mountOptions:
    - hard
    - nfsvers=4.1
  nfs:
    path: /tmp
    server: 172.17.0.2
