现在没有，执行安装 kubectl create deployment nginx --image=nginx

[root@k8smaster ~]# kubectl create deployment nginx --image=nginx
deployment.apps/nginx created

查看状态kubectl get pod

[root@k8smaster ~]# kubectl get pod
NAME                     READY   STATUS    RESTARTS   AGE
nginx-85b98978db-w87hr   1/1     Running   0          70s

查看service服务 kubectl get svc

[root@k8smaster ~]# kubectl get svc
NAME         TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)        AGE
kubernetes   ClusterIP   10.66.0.1     <none>        443/TCP        46h
nginx        NodePort    10.66.32.86   <none>        80:31617/TCP   7m56s

80（容器内部端口访问）:31617（外部端口）

容器编排 kubectl expose deployment nginx --port=80 --type=NodePort
浏览器打开：http://192.168.116.104:31617/

效果

查看节点、服务、控制器、容器命令：

#查看node节点
kubectl get node(s)
#查看服务端口
kubectl get service(s)
#查看控制器
kubectl get deployment (deploy)
#查看pod容器有哪些docker
kubectl get pod(s)
