Windows 10 开启 Docker Desktop 中的 Kubernetes

1. 开启 ExpressVPN

2. 启动 Docker Desktop

3. Settings > Kubernetes > Enable Kubernetes

4. 开启后，需要等待一段时间，会自动下载 images 文件，之后 Kubernetes 会主动重新启动

5. 如果 Kubernetes 没有启动成功，尝试重启 Docker Desktop
   

6. Kubernetes 正常启动后，Docker Desktop 中2个图标都是绿色

7. 检查 Kubernetes cluster 状态

   kubectl get nodes
   # Kubernetes 集群的系统容器 默认不会在 docker 中显示，通过以下docker命令是看不到的
   docker container ls
   docker info

8. 使用 kubectl 部署 Kubernetes Dashboard v2.6.0

   # 部署 Kubernetes Dashboard v2.6.0
   kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.0/aio/deploy/recommended.yaml
   # 启动代理
   kubectl proxy
   # 代理正常启动后会显示：Starting to serve on 127.0.0.1:8001
   # 创建管理员账号 kubernetes-dashboard ，该账号仅有少量权限
   kubectl -n kubernetes-dashboard create token kubernetes-dashboard
   # 创建成功后会显示 Token

9. 访问 Kubernetes Dashboard http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/
   

10. 选择 Token ，在下面输入框输入 kubernetes-dashboard 的 Token

11. 登录进入后可以修改默认语言
    

    

12. 通过以下命令可以将 kubernetes-dashboard 账号、规则删除，可以参考 Creating sample user

    kubectl -n kubernetes-dashboard delete serviceaccount kubernetes-dashboard
    kubectl -n kubernetes-dashboard delete clusterrolebinding kubernetes-dashboard
    1

13. 通过创建如下 account.yaml 文件来创建一个具有全部管理权限的用户

    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

14. 运行命令

    kubectl apply -f ./account.yaml
    kubectl -n kubernetes-dashboard create token admin-user

15. 注意查看内容的时候，使用的是 default 命名空间，是不包含 kubernetes 系统服务的
    

    

16. 可以 运行一个示例 Example Voting App

    # 创建 vote 命名空间
    kubectl create namespace vote
    # 创建服务
    kubectl create -f k8s-vote/
    # 检查服务启动情况
    kubectl -n vote get pods
