创建应用

kubectl apply -f dashboard.yaml

查看Dashboard的Pod是否运行

[root@containerd-kube-master ~]# kubectl get pods --all-namespaces
NAMESPACE              NAME                                        READY   STATUS    RESTARTS   AGE
kubernetes-dashboard   dashboard-metrics-scraper-8c47d4b5d-t92v9   1/1     Running   0          26m
kubernetes-dashboard   kubernetes-dashboard-6c75475678-zlqn7       1/1     Running   0          26m

修改Dashboard的Services

[root@containerd-kube-master ~]# kubectl edit services kubernetes-dashboard  -n kubernetes-dashboard
# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be

改完以后一定要看一眼生效无生效啊

  • 查看到TYPE如果是NodePort
  • 查看PORT对应443映射到了30000端口
[root@containerd-kube-master ~]# kubectl get services --all-namespaces

新版本中默认不存储secret的加密数据了,所以如果你想使用Token进行登录的话,你需要新建一个用户并且绑定角色

  • 新建一个user.yaml
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
[root@containerd-kube-master ~]# kubectl apply -f user.yaml

基于admin-user创建一个token,然后把输出的token粘贴到Dashboard

[root@Online-Beijing-master1 ~]# kubectl create token admin-user -n kubernetes-dashboard
