Kubernetes Dashboard 是一个通用的、基于Web的UI，用于Kubernetes集群管理。
它允许用户管理群集中运行的应用程序并对其进行故障排除，以及管理群集本身。
不同 Kubernetes Dashboard 支持的 Kubernetes 版本不同，可查看 Kubernetes Dashboard 发版日志中的说明：https://github.com/kubernetes/dashboard/releases ，下面列举最近几版的版本支持（仅列举了 完全支持的版本范围）
国内GitCode镜像仓库：https://gitcode.net/mirrors/kubernetes/dashboard

安装
- 在管理节点上执行
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml
- 查看是否创建完成
# kubernetes（k8s）Dashboard 的命名空间是 kubernetes-dashboard
kubectl get pods -n kubernetes-dashboard -o wide
[root@centos-7-9-14 ~]# kubectl get pods -n kubernetes-dashboard -o wide

- 修改 kubernetes-dashboard 服务，使其支持远程访问
# https://github.com/kubernetes/dashboard/blob/master/docs/user/accessing-dashboard/README.md
kubectl -n kubernetes-dashboard edit service kubernetes-dashboard
将 type: ClusterIP 修改成 type: NodePort 即可
- 修改完成后，再次查看 kubernetes-dashboard 服务
kubectl -n kubernetes-dashboard get service kubernetes-dashboard
[root@centos-7-9-14 ~]# kubectl -n kubernetes-dashboard get service kubernetes-dashboard
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes-dashboard NodePort 10.108.225.163 <none> 443:30320/TCP 54m
[root@centos-7-9-14 ~]#
- 由上一步执行的结果可以得出，使用 30320 即可访问 kubernetes-dashboard 服务
假如集群的IP为 192.168.80.14，访问地址为 https://192.168.80.14:30320 - 创建服务帐户
vim dashboard-adminuser.yaml
apiVersion: v1
kind: ServiceAccount
metadata:name: admin-usernamespace: kubernetes-dashboard
kubectl apply -f dashboard-adminuser.yaml
- 创建群集角色绑定
vim cluster-admin.yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:name: admin-user
roleRef:apiGroup: rbac.authorization.k8s.iokind: ClusterRolename: cluster-admin
subjects:
- kind: ServiceAccountname: admin-usernamespace: kubernetes-dashboard
kubectl apply -f cluster-admin.yaml
- 获取持有者令牌
# 指定有效期：--duration=315360000s
# 315360000s 代表 10年
kubectl -n kubernetes-dashboard create token admin-user
- 使用上述令牌即可登录系统
- 其他命令
kubectl -n kubernetes-dashboard delete serviceaccount admin-user
kubectl -n kubernetes-dashboard delete clusterrolebinding admin-user
