calico-kube-controllers pod容器未就绪

####### 在一台机器上装k8s单节点集群，因/目录空间较小，便将docker和kubelet的存储目录迁移至新盘挂载目录。将数据拷贝时没注意目录权限问题，导致重启docker和kubelet后 ，calico容器未就绪，查看日志提示没有权限写入就绪状态到/sttaus/status.json文件。 因为进入pod命令行提示无bash ,sh，故通过修改calico-kube-controllers deployments，增加volume挂载到本地，赋权修改属组后容器就绪正常

  报错日志

编辑deployments/calico-kube-controllers
kubectl edit deployments/calico-kube-controllers -n kube-system
添加如下
    volumeMounts:
    - mountPath: /status
      name: status
volumes:
- hostPath:
    path: /var/run/calico/status
    type: ""
  name: status
到宿主机目录查看/var/run/calico/status
发现status.json文件是polkitd:root 用户属组，修改/var/run/calico/status目录属组用户为polkitd:root后，容器正常
