安装Dashboard

1. 创建 Dashboard pod

   kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml
   

2. 查看 Dashboard pod 健康状态

   kubectl get pods -n kube-system
   

   

   • 如果处于ImagePullBackOff状态，镜像拉取失败， 使用命令 kubectl describe pods kubernetes-dashboard-cd4778d69-7stbb -n kube-system 查看pod日志

     Events:

   • ImagePullBackOff解决办法： 手动拉取镜像， 并修改标签

     # 手动拉取镜像：注意版本号
     docker pull loveone/kubernetes-dashboard-amd64:v1.10.1
     # 修改标签：注意版本号，修改自己报错日志的版本号
     docker tag loveone/kubernetes-dashboard-amd64:v1.10.1 k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1
     # 重新创建Dashboard pod
     kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml
     
     kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml
     

3. 启动 kubectl proxy

    kubectl proxy -p 8000 # 默认端口号 80001 
   

4. 页面访问 http://localhost:8000/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#/login

   

5. 创建 ServiceAccount

   • 本地创建k8s-admin.yaml

     apiVersion: v1
     kind: ServiceAccount
     metadata:
       name: admin-user
       namespace: kubernetes-dashboard
     ---
     apiVersion: rbac.authorization.k8s.io/v1
     kind: ClusterRoleBinding
     metadata:
       name: admin-user
     roleRef:
       apiGroup: rbac.authorization.k8s.io
       kind: ClusterRole
       name: cluster-admin
     subjects:
     - kind: ServiceAccount
       name: admin-user
       namespace: kubernetes-dashboard
     

   • 创建service account

     kubectl apply -f k8s-admin.yaml
     

   • 获取token

     kubectl -n kubernetes-dashboard create token admin-user
     

6. 在页面输入token，登陆即可
