<!--
 In computing, a proxy is a server that acts as an intermediary for a remote
service.
-->
在计算机领域，代理指的是充当远程服务中介的服务器。


<!--more-->

<!--
A client interacts with the proxy; the proxy copies the client's data to the
actual server; the actual server replies to the proxy; the proxy sends the
actual server's reply to the client.
-->
客户端与代理进行交互；代理将客户端的数据复制到实际服务器；实际服务器回复代理；代理将实际服务器的回复发送给客户端。

[kube-proxy](/docs/reference/command-line-tools-reference/kube-proxy/) is a
network proxy that runs on each node in your cluster, implementing part of
the Kubernetes {{< glossary_tooltip term_id="service">}} concept.
-->
[kube-proxy](/zh/docs/reference/command-line-tools-reference/kube-proxy/) 是集群中每个节点上运行的网络代理，实现了部分 Kubernetes {{< glossary_tooltip term_id="service">}} 概念。

<!--
You can run kube-proxy as a plain userland proxy service. If your operating
system supports it, you can instead run kube-proxy in a hybrid mode that
achieves the same overall effect using less system resources.
-->
你可以将 kube-proxy 作为普通的用户态代理服务运行。
如果你的操作系统支持，则可以在混合模式下运行 kube-proxy；该模式使用较少的系统资源即可达到相同的总体效果。
