- Kubernetes Dashboard 是基于 Kubernetes 集群的通用的、基于 Web 的 UI。它允许用户管理集群中运行的应用程序并对其进行故障排除，以及管理集群。
1、下载官网yaml文件
wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml官网：https://github.com/kubernetes/dashboard
目前v2.7.0 是最新版，其他版本可以到官网下载。
2、修改recommended.yaml
默认创建名为 "kubernetes-dashboard“ 的service 是ClusterIP 类型，我们要通过外网访问的话需要修改下，这里我们修改为 NodePort。
编辑 recommended.yaml 在大约 40行的位置添加一行 type: NodePort

[root@172-17-0-46 data]# kubectl apply -f recommended.yaml
namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created

clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created
[root@172-17-0-46 data]# 4、查看资源是否已就绪
[root@172-17-0-46 data]# kubectl get all -n kubernetes-dashboard -o wide

[root@172-17-0-46 data]# 5、测试访问
访问链接为 https://节点IP:kubernetes-dashboard 服务端口30443/
例如：https://172.17.0.43:30443/
访问到如下页面说明成功了
6、创建访问账号
默认创建的serviceaccount/kubernetes-dashboard 不是所有权限，所以我们要创建一个所有权限的账号。
[root@172-17-0-46 data]# cat dashboard-admin.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
labels:
k8s-app: kubernetes-dashboard
name: dashboard-admin
namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: dashboard-admin-cluster-role
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: dashboard-admin
namespace: kubernetes-dashboard
[root@172-17-0-46 data]#
[root@172-17-0-46 data]#
[root@172-17-0-46 data]# kubectl apply -f dashboard-admin.yaml
serviceaccount/dashboard-admin created
clusterrolebinding.rbac.authorization.k8s.io/dashboard-admin-cluster-role created
[root@172-17-0-46 data]# 7、获取账号token登录dashboard
[root@172-17-0-46 data]# kubectl describe serviceaccount dashboard-admin -n kubernetes-dashboard

Labels: k8s-app=kubernetes-dashboard
Annotations: <none>

[root@172-17-0-46 data]#
[root@172-17-0-46 data]# kubectl describe secrets dashboard-admin-token-nbvc2 -n kubernetes-dashboard # 此处的"dashboard-admin-token-nbvc2"来自上一个命令返回中的Tokens的值
Name: dashboard-admin-token-nbvc2
Namespace: kubernetes-dashboard
Labels: <none>
Annotations: kubernetes.io/service-account.name: dashboard-admin
kubernetes.io/service-account.uid: 7166a214-a44f-409d-98f0-ae73a0a72bac
