[Gizmos777]

Hello. I use cifs plugin and it work if i use as pod. I have decided as deployment, but it doesn't work

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  namespace: services
  labels:
    app: nginx
spec:
  replicas: 1
  selector:
    matchLabels:

        ports:
        - containerPort: 80
        imagePullPolicy: IfNotPresent
        volumeMounts:
        - name: cifs-share
          mountPath: /data

          requests:
            cpu: "200m"
            memory: 128Mi
      volumes:

        flexVolume:
          driver: fstab/cifs
          fsType: cifs
          options:
            mountOptions: dir_mode=0755,file_mode=0644,noperm
            networkPath: //server/data
          secretRef:
            name: cifs-secret

While mostly a workaround, could you try using volume claims?

To add to this, I have been using this module from PV/PVC within a deployment, unfortunately it only works as ReadOnly when deployed this way. If I attempt to mount it as ReadWrite the pods will fail to launch.

For me this is working within a deployment. Here is my YAML, so you can compare:

      volumes:
