kubernetes Dashboard是什么？
Dashboard是kubernetes的Web GUI，可用于在kubernetes集群上部署容器化应用，应用排错，管理集群本身及其附加的资源等，它常被管理员用于集群及应用速览，创建或修改单个资源，（如Deployments，Jobs，DaemonSets的等）以及扩展Deployment，启动滚动更新，重启pod或使用向导部署一个新应用等。

root@K8s-node2:~# docker pull kubernetesui/dashboard:v2.0.0-rc6
root@K8s-node2:~# docker pull kubernetesui/metrics-scraper:v1.0.3
root@K8s-master:/usr/local/src# vim dash_board-2.0.0-rc6.yml
containers:
        - name: kubernetes-dashboard
          image: kubernetesui/dashboard:v2.0.0-rc6
          imagePullPolicy: Always
kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: dashboard-metrics-scraper
  name: dashboard-metrics-scraper
  namespace: kubernetes-dashboard
  

kubectl apply -f dash_board-2.0.0-rc6.yml
root@K8s-master:~# kubectl apply -f ad_min-user.yml 

2.获取token

root@K8s-master:~# kubectl get secret -A | grep admin-user
root@K8s-master:~# kubectl describe secret admin-user-token-f8dxt -n kubernetes-dashboard
ard

3.验证nodeport
root@K8s-master:/usr/local/src# kubectl get svc -A
