docker重启失败,重装docker和恢复服务操作：

yum remove docker*
yum install docker-ce
配置/etc/docker/daimon.json
systemctl start docker
systemctl enable docker

启动服务：
（1）检查swap内存，需要处于关闭状态，关闭命令：
swapoff -a
(2) 重启kubelet:
systemctl restart kubelet
(3) 等待集群重启，正常情况下执行docker ps,会有很多容器启动，
查看服务： kubectl get pod -n kube-system
存储服务： kubectl get pod -n rook-ceph
