<!--
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/extend-cluster/#extensions) 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。
因此，大多数 Kubernetes 用户将不需要
安装[扩展组件](/zh-cn/docs/concepts/extend-kubernetes/extend-cluster/#extensions)，
需要编写新的扩展组件的用户就更少了。
