 <!-- [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](/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 Kubernetes {{< glossary_tooltip term_id="service">}} 概念的一部分。

<!-- kube-proxy maintains network rules on nodes. These network rules allow
network communication to your Pods from network sessions inside or outside
of your cluster. -->
kube-proxy 维护节点上的网络规则。这些网络规则允许从集群内部或外部的网络会话与 Pod 进行网络通信。

<!-- kube-proxy uses the operating system packet filtering layer if there is one
and it's available. Otherwise, kube-proxy forwards the traffic itself. -->
如果有 kube-proxy 可用，它将使用操作系统数据包过滤层。否则，kube-proxy 会转发流量本身。
