一、部署dashboard

### --- Dashboard概述

~~~     Dashboard用于展示集群中的各类资源，
~~~     同时也可以通过Dashboard实时查看Pod的日志和在容器中执行一些命令等。

二、安装指定版本dashboard

### --- 切换到dashboard部署目录下

[root@k8s-master01 ~]# cd /root/k8s-ha-install/dashboard/

### --- 部署dashboard

[root@k8s-master01 dashboard]# kubectl  create -f .
~~~     注：输出结果：
serviceaccount/admin-user created
clusterrolebinding.rbac.authorization.k8s.io/admin-user created
namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created 

### --- 查看dashboard.pod状态
~~~     查看dashboard部署运行结果

[root@k8s-master01 dashboard]# kubectl get po -n kubernetes-dashboard -owide
NAME                                         READY   STATUS    RESTARTS   AGE   IP               NODE           NOMINATED NODE   READINESS GATES
dashboard-metrics-scraper-7645f69d8c-w8hnh   1/1     Running   0          70s   172.25.244.194   k8s-master01   <none>           <none>
kubernetes-dashboard-78cb679857-472kx        1/1     Running   0          70s   172.27.14.194    k8s-node02     <none>           <none> 

三、登录dashboard-UI

### --- Chrome客户端配置
~~~     在谷歌浏览器（Chrome）启动文件中加入启动参数，用于解决无法访问Dashboard的问题：

--test-type --ignore-certificate-errors

### --- 查看dashboard.service端口号
~~~     更改dashboard的svc为NodePort：
~~~     注：将ClusterIP更改为NodePort（如果已经为NodePort忽略此步骤）：

[root@k8s-master01 dashboard]#  kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard
  type: NodePort

### --- 查看端口号

[root@k8s-master01 dashboard]# kubectl get svc kubernetes-dashboard -n kubernetes-dashboard
NAME                   TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)         AGE
kubernetes-dashboard   NodePort   10.109.117.76   <none>        443:32522/TCP   4m18s

### --- 查看dashboard-token值
~~~     查看token值

[root@k8s-master01 dashboard]# kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
Name:         admin-user-token-8t87f
Namespace:    kube-system
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: admin-user
              kubernetes.io/service-account.uid: c2951d8b-03f2-4dc3-b61c-993033345580
Type:  kubernetes.io/service-account-token

四、登录dashboard：

### --- 登录dashboard：

~~~     根据实例端口号，通过任意安装了kube-proxy的宿主机或者VIP的IP+端口即可访问到dashboard：
~~~     访问Dashboard：https://192.168.1.11:18282（请更改18282为自己的端口），
~~~     选择登录方式为令牌：即token方式
~~~     # 将token值输入到令牌后，单击登录即可访问Dashboard
