看IngressNginx的文档时，发现了一种RBAC的权限罗列方式，如下：
以下权限授予一个名为ingress-nginx的ClusterRole：
- configmaps、endpoints、nodes、pods、secrets：list、watch
- nodes：get
- services、ingress：get、list、watch
- events：create、patch
- ingress/status：update
以下权限授予一个名为ingress-nginx的Role：
- configmaps、pods、secrets：get
- endpoints：get
- configmaps：get、update
- configmaps：create
其对应的配置清单如下：

很有趣，我觉得这样把资源罗列下来，更有利于自己之后的开发工作。当然我先解决不需要如此升入的学习，我们的应用目前甚至不会去获取集群的任何资源，所以即使不为它们设置ServiceAccount，我觉得都是可以的。
