初始化后的集群只能通过kubectl命令来管理集群，无法界面操作。Dashboard是基于Web的kubernetes用户界面，可以使用dashboard将容器应用部署到kubernetes集群中，也可以对容器应用排错，还能管理集群资源。

Dashboard还可以展示kubernetes集群中的资源状态信息和所有报错信息。

1、下载dashboard并修改配置

GitHub地址：https://github.com/kubernetes/dashboard
wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml
设置为Service NodePort类型


vi recommended.yaml

2、部署

[root@k8s-master ~]# kubectl apply -f recommended.yaml

3、查看dashboard情况

[root@k8s-master ~]# kubectl get pods -n kubernetes-dashboard
NAME                                         READY   STATUS    RESTARTS   AGE
dashboard-metrics-scraper-5657497c4c-zvv2b   1/1     Running   0          12m
kubernetes-dashboard-78f87ddfc-h8l6h         1/1     Running   0          12m

4、创建登录用户

cat >ServiceAccount.yaml<<EOF
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
EOF
[root@k8s-master ~]# kubectl apply -f ServiceAccount.yaml

5、创建并获取登录token

[root@k8s-master ~]# kubectl -n kubernetes-dashboard create token admin-user

6、配置hosts登录dashboard web

cat >> etc/hosts << EOF
10.0.0.5 cluster-endpoint
EOF

在登录的window主机也要配置hosts

配置路径：C:\Windows\System32\drivers\etc

7、登录dashboard界面

https://cluster-endpoint:31443

复制第5步获取的token进行登录

8、登录后界面

登录后默认进入default命名空间中。
