minikube的简单命令

之前安装好了minikube，下面使用一些关于minikube的相关命令：

• 获取有关运行节点的信息

[zhoujing@zhouj Code]$ kubectl get pod
No resources found.
[zhoujing@zhouj Code]$ kubectl get node
NAME       STATUS    AGE       VERSION
minikube   Ready     1d        v1.7.0
#创建名为hello-minikube的pod
[zhoujing@zhouj Code]$ kubectl run hello-minikube --image=gcr.io/google_containers/echoserver:1.4 --port=8080
deployment "hello-minikube" created
[zhoujing@zhouj Code]$ kubectl get pod
NAME                             READY     STATUS              RESTARTS   AGE
hello-minikube-180744149-r908g   0/1       ContainerCreating   0          1m
[zhoujing@zhouj Code]$ kubectl get pod
NAME                             READY     STATUS    RESTARTS   AGE
hello-minikube-180744149-r908g   1/1       Running   0          6m

• 描述运行节点的所有信息

[zhoujing@zhouj Code]$ kubectl describe pod hello-minikube-180744149-r908g

• 暴露pod的端口；显示访问地址

[zhoujing@zhouj Code]$ kubectl expose deployment  hello-minikube --type=NodePort
service "hello-minikube" exposed
[zhoujing@zhouj Code]$ minikube service hello-minikube --url
http://192.168.99.100:30299

  浏览网页,显示内容如下：
