1.在k8s mster节点执行
1.kubectl get nodes 发现node节点没起来
[root@guanbin-k8s-master ~]# kubectl get nodes NAME STATUS ROLES AGE VERSION guanbin-k8s-master Ready master 38d v1.18.0 guanbin-k8s-node NotReady <none> 38d v1.18.2
2.执行 kubectl describe node guanbin-k8s-node | grep Ready 发现是node节点docker未启动
[root@guanbin-k8s-master ~]# kubectl describe node guanbin-k8s-node | grep Ready Ready False Wed, 27 May 2020 22:41:13 +0800 Wed, 27 May 2020 18:10:34 +0800 KubeletNotReady [container runtime is down, PLEG is not healthy: pleg was last seen active 48h9m36.439003506s ago; threshold is 3m0s, Container runtime not ready: RuntimeReady=false reason:DockerDaemonNotReady message:docker: failed to get docker version: Cannot connect to the Docker daemon at unix:///var/run/docker.sock.

2.查看node节点的docker服务

3.原因是/etc/docker/daemon.json中改了东西不对，导致docker的daemon服务没起来
重新修改下/etc/docker/daemon.json就好了，原因是之前是改为了127.0.0.1：5000导致服务启动报错了
