<!--
You can extend Kubernetes by adding controllers to your cluster, beyond the built-in
controllers that come as part of Kubernetes itself.

If a running application acts as a controller and has API access to carry out tasks
against a custom resource that's defined in the control plane, that's an example of
the Operator pattern.

除了使用作为 Kubernetes 自身一部分的内置控制器之外，你还可以通过
将控制器添加到集群中来扩展 Kubernetes。

如果正在运行的应用程序能够充当控制器并通过 API 访问的方式来执行任务操控
那些在控制平面中定义的自定义资源，这就是一个 operator 模式的示例。
