将kubernetes-dashboard绑定cluster-admin权限

编写yaml文件
cat kubernetes-dashboard-admin_clusterroles.yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: kubernetes-dashboard
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard

kubectl apply -f kubernetes-dashboard-admin_clusterroles.yaml
clusterrolebinding.rbac.authorization.k8s.io "kubernetes-dashboard" created

登陆WEB-UI页面，数据恢复正常

报错：

[root@pro1 WEB-UI]# kubectl apply -f kubernetes-dashboard-admin_clusterroles.yaml
The ClusterRoleBinding "kubernetes-dashboard" is invalid: roleRef: Invalid value: rbac.RoleRef{APIGroup:"rbac.authorization.k8s.io", Kind:"ClusterRole", Name:"cluster-admin"}: cannot change roleRef

解决：

[root@pro1 WEB-UI]# kubectl delete -f kubernetes-dashboard-admin_clusterroles.yaml 
clusterrolebinding.rbac.authorization.k8s.io "kubernetes-dashboard" deleted
[root@pro1 WEB-UI]# 
[root@pro1 WEB-UI]# kubectl apply -f kubernetes-dashboard-admin_clusterroles.yaml
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
