在kubernetes中完成的所有操作都是通过命令行工具kubectl完成的。其实，为了提供更丰富的用户体验,kubernetes还开发了一个基于web的用户界面(Dashboard)。用户可以使用Dashboard部署容器化的应用，还可以监控应用的状态，执行故障排查以及管理kubernetes中各种资源。 

#下载
wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.1.0/aio/deploy/recommended.yaml

官方的kubernetes-dashboard.yaml文件中service的type类型为clusterIp(service默认类型)，这种方式要访问dashboard需要通过代理，所以我们改为NodePort方式，这样部署完后，就可以直接通过

  ports:
  - port: 30009
    targetPort: 8443
  selector:

kubectl apply -f recommended.yaml

kubectl get pod,svc -n kubernetes-dashboard -o wide
