How can I set port for NFS volume?
I have NFS server on port 30000(TCP). I want to make auto provisioning system with the NFS server, so I applied provisioner deployment:
kind: Deployment
apiVersion: apps/v1
metadata:
name: nfs-provisioner
spec:
replicas: 1
selector:
matchLabels:
app: nfs-provisioner
strategy:
type: Recreate
template:
metadata:
labels:
app: nfs-provisioner
spec:
serviceAccountName: nfs-provisioner-sa
containers:
- name: nfs-provisioner
image: k8s.gcr.io/sig-storage/nfs-subdir-external-provisioner:v4.0.2
volumeMounts:
- name: nfs-root
mountPath: /persistentvolumes
env:
- name: PROVISIONER_NAME
value: k8s-sigs.io/nfs-subdir-external-provisioner
- name: NFS_SERVER
value: "192.168.0.7:30000"
- name: NFS_PATH
value: /provision/
volumes:
- name: nfs-root
nfs:
server: "192.168.0.7:30000"
path: /provision/
But it is not works and pod has next description.

I found that kubernetes uses wrong command args, -t nfs 192.168.0.7:30000:/provision/ instead of -o port=30000 -t nfs 192.168.0.7:/provision/. So I have looked for API Reference about NFS to know how can I set port for NFS server, but there is no ‘port’ option.
How can I set port for NFS volume?
