扩展组件（Extensions）是扩展并与 Kubernetes 深度集成以支持新型硬件的软件组件。

<!--
Many cluster administrators use a hosted or distribution instance of Kubernetes. These clusters
come with extensions pre-installed. As a result, most Kubernetes users will not need to install
[extensions](/docs/concepts/extend-kubernetes/) and even fewer users will need to author new ones. 
-->
许多集群管理员会使用托管的 Kubernetes 或其某种发行包，这些集群预装了扩展组件。
因此，大多数 Kubernetes 用户将不需要安装[扩展组件](/zh-cn/docs/concepts/extend-kubernetes/)，
需要编写新的扩展组件的用户就更少了。
