 You can [download Kubernetes](/releases/download/) to deploy a Kubernetes cluster
 on a local machine, into the cloud, or for your own datacenter.
 
+Several [Kubernetes components](/docs/concepts/overview/components/) such as `kube-apiserver` or `kube-proxy` can also be
+deployed as [container images](/releases/download/#container-images) within the cluster.
+
+It is **recommended** to run Kubernetes components as container images wherever
+that is possible, and to have Kubernetes manage those components.
+Components that run containers - notably, the kubelet - can't be included in this category.
+
 If you don't want to manage a Kubernetes cluster yourself, you could pick a managed service, including
 [certified platforms](/docs/setup/production-environment/turnkey-solutions/).
 There are also other standardized and custom solutions across a wide range of cloud and
 bare metal environments.

+
+**建议**尽可能将 Kubernetes 组件作为容器镜像运行，并且让 Kubernetes 管理这些组件。

 如果你不想自己管理 Kubernetes 集群，则可以选择托管服务，包括[经过认证的平台](/zh-cn/docs/setup/production-environment/turnkey-solutions/)。
 在各种云和裸机环境中，还有其他标准化和定制的解决方案。
