When I try to deploy node-red in k8s, there will be an error that no nfs support.
Pls add nfs when docker package.

Logs show:

This is my yaml

spec:
  type: NodePort
  ports:
    - port: 1880
      nodePort: 8720

  selector:
    k8s-app: node-red

kind: PersistentVolumeClaim

  namespace: default

        volumeMounts:

the stock node-red docker file is kept as minimalistic as possible.

If you have package requirements its best to build your own docker node-red image. Its easy....follow the directions.

Mounting volumes should be handled by the the machine hosting the Kubernetes node not the individual containers.

Just to be clear, I'm saying you need to add NFS mount support to your K8s node, not the container.
