kubernetes – local persistant volume & nodeAffinity

  • 0

[ad_1]

I am using local persistant volumes in my kubernetes cluster, I have currentky two worker nodes in my cluster(node1, node2). So while creating local Peristant Volume I have added node affinity with these nodes.

  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/hostname
          operator: In
          values:
          - node1
          - node2

10 deployments are working using these PVs. Now, I want to add a new worker node to the cluster(node3). I tried to modify the Persistent Volume but I can’t modify the nodeAffinity as this is showing “field is immutable”.
How should I proceed now? If I don’t modify the PV, pods will not get scheduled on the new worker node?

How to tackle this situation?
