Kubernetes 常用命令

1.查看节点状态

[root@master1 ~]# kubectl get nodes
NAME      STATUS   ROLES    AGE    VERSION
master1   Ready    master   113m   v1.14.2
master2   Ready    master   105m   v1.14.2
master3   Ready    master   102m   v1.14.2
node1     Ready    <none>   101m   v1.14.2
node2     Ready    <none>   43m    v1.14.2
node3     Ready    <none>   43m    v1.14.2

2.查看系统静态pod运行情况

[root@master1 ~]# kubectl get pods -n kube-system -o wide
NAME                                       READY   STATUS    RESTARTS   AGE    IP              NODE      NOMINATED NODE   READINESS GATES
