k8s 1.10 关于rbac的坑

apiserver  启动加上--authorization-mode=RBAC 开启rbac

会生成默认role，最高权限位cluster-admin的cluster role

再关闭rbac(不加--authorization-mode=RBAC启动apiserver)

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: User
    name: 7dd70763-c067-6232-a90b-d6c1a9eef026
 
绑定给admin用户
 
再开启， 可以使用admin用户操作
