Intended to provide an NFS service for a PersistentVolumeClaim in Kubernetes.

Usage

Kubernetes Pod and Service example

apiVersion: v1
kind: Pod
metadata:
  name: unfs3
  labels:
    app: unfs3
  spec:
    containers:
    - name: unfs3
      image: nimbix/unfs3
      imagePullPolicy: Always
      volumeMounts:
      - mountPath: /export
        name: export-vol
  restartPolicy: Always
  volumes:
    - name: export-vol
  persistentVolumeClaim:
    claimName: mypvc
---
apiVersion: v1
kind: Service
metadata:
  name: unfs3
spec:
  type: ClusterIP
  ports:
  - name: tcp111
    port: 111
    targetPort: 111
    protocol: TCP
  - name: udp111
    port: 111
    targetPort: 111
    protocol: UDP
  - name: tcp2049
    port: 2049
    targetPort: 2049
    protocol: TCP
  - name: udp2049
    port: 2049
    targetPort: 2049
    protocol: UDP
  selector:
    app: unfs3

Mount the /export path from the service's ClusterIP after creation. Note that the PersistentVolumeClaim must exist and should be referred to in the pod spec as whatever you named it.
