本文讲述的是如何部署K8s的web UI，前提是已经有一个k8s集群后，按照如下步骤进行即可。(如下步骤都是在master节点上进行操作)

部署到 K8S 集群

#部署
[root@master ~]# kubectl apply -f dashboard.yaml
#查看pod状态
[root@master ~]# kubectl get pods -n kube-system |grep dashboard
#查看端口映射
[root@master ~]# kubectl get svc -n kube-system

访问测试：
在浏览器输入：https://192.168.8.222:30000

Token （令牌） 认证方式

• 1. 授权 (所有 namespace )

#创建serviceaccount
[root@master ~]# kubectl create serviceaccount dashboard-serviceaccount -n kube-system
#创建clusterrolebinding
 kubectl create clusterrolebinding dashboard-cluster-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-serviceaccount

• 2. 获取令牌（用于网页登录）

#查看口令列表
[root@master ~]# kubectl get secret -n kube-system |grep dashboard-serviceaccount-token
#获取口令
[root@master ~]# kubectl describe secret dashboard-serviceaccount-token-nz7xd -n kube-system

• 3. 网页登录

     
     
     选择令牌登录

configing 认证

• 1. 创建 conf 文件

# 复制 admin.conf
root@k8s-master: cp /etc/kubernetes/admin.conf /root/admin.conf
# 在/root/admin.conf 末尾添加 token
- name: kubernetes-admin
  user:
    client-certificate-data: ...
    client-key-data: ...
    token: "在这里加上token"

• 2. 在浏览器中选 kubeconfig 文件登录
