官方文档

Github文档

1. 部署 Dashboard UI

   kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml
   

2. 编辑对外 svc 文件

   vi kubernetes-dashboard-svc.yaml
   

   内容如下

   apiVersion: v1
   kind: Service
   metadata:
     name: kubernetes-dashboard-40000
     labels:
       k8s-app: kubernetes-dashboard
     namespace: kubernetes-dashboard
   spec:
     ports:
     - name: kubernetes-dashboard
       nodePort: 40000
       port: 443
       protocol: TCP
       targetPort: 8443
     selector:
       k8s-app: kubernetes-dashboard
     type: NodePort
   

3. 部署

   kubectl apply -f kubernetes-dashboard-svc.yaml
   

4. 查看状态

   kubectl get all -n kubernetes-dashboard
   

5. 获取长期令牌

   vi kubernetes-dashboard-token.yaml
   

   内容如下

   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

     name: admin-user
     namespace: kubernetes-dashboard
   ---
   apiVersion: v1
   kind: Secret
   metadata:
     name: admin-user
     namespace: kubernetes-dashboard
     annotations:
       kubernetes.io/service-account.name: "admin-user"   
   type: kubernetes.io/service-account-token  
   

6. 创建

   kubectl apply -f kubernetes-dashboard-token.yaml
   

7. 查看 token

   kubectl get secret admin-user -n kubernetes-dashboard -o jsonpath={".data.token"} | base64 -d
