<!--
 The container orchestration layer that exposes the API and interfaces to define, deploy, and manage the lifecycle of containers.
-->
控制平面（Control Plane）是指容器编排层，它暴露 API 和接口来定义、
部署容器和管理容器的生命周期。

<!--
 This layer is composed by many different components, such as (but not restricted to):

 * {{< glossary_tooltip text="etcd" term_id="etcd" >}}
 * {{< glossary_tooltip text="API Server" term_id="kube-apiserver" >}}
 * {{< glossary_tooltip text="Scheduler" term_id="kube-scheduler" >}}
 * {{< glossary_tooltip text="Controller Manager" term_id="kube-controller-manager" >}}
 * {{< glossary_tooltip text="Cloud Controller Manager" term_id="cloud-controller-manager" >}}

 These components can be run as traditional operating system services (daemons) or as containers. The hosts running these components were historically called {{< glossary_tooltip text="masters" term_id="master" >}}.
-->
这个编排层是由多个不同的组件组成，例如以下（但不限于）几种：

 * {{< glossary_tooltip text="etcd" term_id="etcd" >}}
 * {{< glossary_tooltip text="API 服务器" term_id="kube-apiserver" >}}
 * {{< glossary_tooltip text="调度器" term_id="kube-scheduler" >}}
 * {{< glossary_tooltip text="控制器管理器" term_id="kube-controller-manager" >}}
 * {{< glossary_tooltip text="云控制器管理器" term_id="cloud-controller-manager" >}}

这些组件可以以传统的系统服务运行也可以以容器的形式运行.运行这些组件的主机过去称为 master 节点。
