2. 部署dashboard主yaml配置文件
#修改镜像下载地址
[root@hs-k8s-master01 dashboard]# cat kubernetes-dashboard.yaml |grep image
          image: registry.cn-hangzhou.aliyuncs.com/google_containers/dashboard:v2.0.0-rc3
          image: registry.cn-hangzhou.aliyuncs.com/google_containers/metrics-scraper:v1.0.3


[root@hs-k8s-master01 dashboard]# kubectl apply -f kubernetes-dashboard.yaml
secret/kubernetes-dashboard-certs created
serviceaccount/kubernetes-dashboard created
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
deployment.apps/kubernetes-dashboard created
service/kubernetes-dashboard created

3. 创建可读可写admin Service Account
[root@hs-k8s-master01 dashboard]# kubectl apply -f admin-user-sa-rbac.yaml
serviceaccount/admin-user created
clusterrolebinding.rbac.authorization.k8s.io/admin-user created

4. 创建只读 read Service Account
[root@hs-k8s-master01 dashboard]# kubectl apply -f read-user-sa-rbac.yaml
serviceaccount/dashboard-read-user created
clusterrolebinding.rbac.authorization.k8s.io/dashboard-read-binding created
clusterrole.rbac.authorization.k8s.io/dashboard-read-clusterrole created

5. 查看
#查看pod运行状态
[root@hs-k8s-master01 dashboard]# kubectl get pod -n kube-system | grep dashboard
dashboard-metrics-scraper-6b66849c9-8lvqd   1/1     Running   0          23m
kubernetes-dashboard-6dc6c4f59-84526        1/1     Running   0          23m


#查看dashboard service
[root@hs-k8s-master01 dashboard]#  kubectl get svc -n kube-system|grep dashboard
dashboard-metrics-scraper   ClusterIP   10.107.131.160   <none>        8000/TCP                 23m
kubernetes-dashboard        NodePort    10.99.144.160    <none>        443:31110/TCP            23m

 
#查看集群服务
[root@hs-k8s-master01 dashboard]# kubectl cluster-info
Kubernetes master is running at https://20.0.0.250:8443
KubeDNS is running at https://20.0.0.250:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
kubernetes-dashboard is running at https://20.0.0.250:8443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.


#查看pod运行日志
[root@hs-k8s-master01 dashboard]# kubectl logs kubernetes-dashboard-6dc6c4f59-84526 -n kube-system

6. 生成证书
供本地google浏览器使用
#生成client-certificate-data
[root@k8s-master01 dashboard]# grep 'client-certificate-data' ~/.kube/config | head -n 1 | awk '{print $2}' | base64 -d >> kubecfg.crt
 

#生成client-key-data
[root@k8s-master01 dashboard]# grep 'client-key-data' ~/.kube/config | head -n 1 | awk '{print $2}' | base64 -d >> kubecfg.key

 
#生成p12
[root@k8s-master01 dashboard]# openssl pkcs12 -export -clcerts -inkey kubecfg.key -in kubecfg.crt -out kubecfg.p12 -name "kubernetes-client"
Enter Export Password:   1
Verifying - Enter Export Password:     1

-rw-r--r-- 1 root root 3084 2月   5 15:33 read-user-sa-rbac.yaml
[root@k8s-master01 dashboard]# sz kubecfg.p12
谷歌浏览器导入证书：
备注把上一步骤的kubecfg.p12 文件导入证书后需要重启浏览器：

7. 导出令牌
[root@hs-k8s-master01 dashboard]#  kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
