Kubernetes NFS server

nfs-server.yaml

# Note - an NFS server isn't really a Kubernetes
# concept. We're just creating it in Kubernetes
# for illustration and convenience. In practice,
# it might be run in some other system.

# Create a service to expose the NFS server
# to pods inside the cluster.

kind: Service
apiVersion: v1
metadata:
  name: nfs-service
spec:
  selector:
    role: nfs
  ports:
    # Open the ports required by the NFS server
    # Port 2049 for TCP
    - name: tcp-2049
      port: 2049
      protocol: TCP

    # Port 111 for UDP
    - name: udp-111
      port: 111
      protocol: UDP

# exposed by the service.
