-Examples of controllers that ship with Kubernetes today are the replication controller, endpoints controller, namespace controller, and serviceaccounts controller.
+Some controllers also run inside the control plane, providing control loops that

-Kubernetes 当前提供的部分控制器例子包括：副本控制器（replication controller）、端点控制器（endpoints controller）、命名空间控制器（namespace controller）、服务账号控制器（serviceaccounts controller）。
+其中一些控制器是运行在控制平面内部的，对Kubernates来说，他们提供核心控制操作。比如：部署控制器（deployment controller）、守护控制器（daemonset controller）、命名空间控制器（namespace controller）、持久化数据卷控制器（persistent volume
+controller）（等）都是运行在{{< glossary_tooltip text="kube-controller-manager" term_id="kube-controller-manager" >}}中的。
