从github上获取k8s网页资源文件
GitHub地址

将6个yaml文件上传至k8s的master节点上

[root@master01 k8s]# mkdir /root/k8s/dashborad
[root@master01 k8s]# cd dashborad/
[root@master01 dashborad]# ls
dashboard-configmap.yaml  dashboard-controller.yaml  dashboard-rbac.yaml  dashboard-secret.yaml  dashboard-service.yaml  k8s-admin.yaml

# 使用yaml文件创建
# 这些yaml文件创建需按顺序
# 不能任意创建
kubectl  create -f dashboard-rbac.yaml
kubectl  create -f dashboard-secret.yaml
kubectl  create -f dashboard-configmap.yaml
kubectl  create -f dashboard-controller.yaml
kubectl  create -f dashboard-service.yaml

[root@master01 dashborad]# kubectl get pods,svc -n kube-system
NAME                                        READY   STATUS    RESTARTS   AGE
pod/kubernetes-dashboard-65f974f565-vvfh2   1/1     Running   0          112s

NAME                           TYPE       CLUSTER-IP   EXTERNAL-IP   PORT(S)         AGE
service/kubernetes-dashboard   NodePort   10.0.0.154   <none>        443:30001/TCP   103s

使用kubectl get pod -o wide -n kube-system命令查看dashboard的pod运行在k8s的哪个节点上

访问节点IP地址的30001端口进入网页

# apply 重新应用修改过的dashboard-controller.yaml
[root@master01 dashborad]# kubectl apply -f dashboard-controller.yaml
Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply

重新应用资源后可能会使资源运行节点发生改变，

使用kubectl get pod -n kube-system -o wide命令查看节点IP

再访问相应的节点IP进入网页

登陆认证使用令牌

下面获取令牌

# 生成令牌
[root@master01 dashborad]# kubectl create -f k8s-admin.yaml
serviceaccount/dashboard-admin created
clusterrolebinding.rbac.authorization.k8s.io/dashboard-admin created
[root@master01 dashborad]# kubectl  get secret -n kube-system

[root@master01 dashborad]# kubectl describe secret dashboard-admin-token-lzzfl -n kube-system
...
