O servidor Kubernetes NFS não pode ser acessado por meio do endpoint de serviço

Implantei o servidor NFS usando o seguinte manifesto

---

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: nfs-pv-provisioning-demo
  namespace: nfs
  labels:
    role: nfs-server
spec:
  storageClassName: aws-gp3
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi

---

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nfs-server
  namespace: nfs
spec:
  replicas: 1
  selector:
    matchLabels:
      role: nfs-server
  template:
    metadata:
      labels:
        role: nfs-server
    spec:
      containers:
      - name: nfs-server
        image: registry.k8s.io/volume-nfs:0.8
        ports:
          - name: nfs
            containerPort: 2049
          - name: mountd
            containerPort: 20048
          - name: rpcbind
            containerPort: 111
        securityContext:
          privileged: true
        volumeMounts:
          - mountPath: /exports
            name: mypvc
      volumes:
        - name: mypvc
          persistentVolumeClaim:
            claimName: nfs-pv-provisioning-demo

---

kind: Service
apiVersion: v1
metadata:
  name: nfs-server
  namespace: nfs
spec:
  ports:
    - name: nfs
      port: 2049
    - name: mountd
      port: 20048
    - name: rpcbind
      port: 111
  selector:
    role: nfs-server

Mas quando eu uso nfs-server.nfs.svc.cluster.localo nome do servidor, não consegui resolver. Funcionou quando eu uso Cluster IP para endpoint de serviço.

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs
  namespace: nfs
spec:
  capacity:
    storage: 1Mi
  accessModes:
    - ReadWriteMany
  nfs:
    server: nfs-server.nfs.svc.cluster.local
    # server: 172.20.144.30
    path: "/"
  mountOptions:
    - nfsvers=4.2

Alguma idéia do que há de errado com essa configuração?
