Kubernetes: 在 pod 中安装 nfs 卷已损坏

https://github.com/kubernetes/kubernetes/pull/35652在 pod 中挂载了 nfs 卷：

apiVersion: v1
kind: Pod
metadata:
  name: demo
spec:
  containers:
  - image: fedora:24
    name: fedora
    imagePullPolicy: Always
    command:
    - /usr/bin/sleep
    - "3600"
    volumeMounts:
    - name: myvol
      mountPath: /mnt
  volumes:
  - name: myvol
    nfs:
      path: /srv/share
      server: localhost
  terminationGracePeriodSeconds: 5

kubectl create -f nfspod.yaml

卡在ContainerCreating

kubectl describe pod demo

请注意 nfs 服务器名称上的前导/ 。
