Mount test or Netapp File system as NFS on K8s

Mount file systems as NFS on EKS or any K8’s. Below test is from EKS

My usecase, where I have to mount existing FS in readOnly mode on kubernetes

Steps

1. Install NFS CSI drivers

curl -skSL https://raw.githubusercontent.com/kubernetes-csi/csi-driver-nfs/master/deploy/install-driver.sh | bash -s master --
kubectl -n kube-system get pod -o wide -l app=csi-nfs-controller
kubectl -n kube-system get pod -o wide -l app=csi-nfs-node

Sample yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  annotations:
    pv.kubernetes.io/provisioned-by: nfs.csi.k8s.io
  name: nfs-pv-server1

    storage: 1Gi  # Placeholder; ignored for NFS
  accessModes:
    - ReadOnlyMany
  mountOptions:
    - nfsvers=4.1
  persistentVolumeReclaimPolicy: Retain
  csi:
    driver: nfs.csi.k8s.io
    volumeHandle: nfs-server1
    volumeAttributes:

      share: /test/server1

      mountPath: "/test/server1"
      readOnly: true
