All default port numbers can be overridden. When custom ports are used those ports need to be open instead of defaults mentioned here. One common example is API server port that is sometimes switched to 443. Alternatively, the default port is kept as is and API server is put behind a load balancer that listens on 443 and routes the requests to API server on the default port. --> ## 工作节点  {#node} | 协议     | 方向      | 端口范围     | 目的                     | 使用者                  | |----------|-----------|-------------|-----------------------|-------------------------| | TCP      | 入站       | 10250       | Kubelet API           | 自身, 控制面             | | TCP      | 入站       | 30000-32767 | NodePort Services†    | 所有                    | † [NodePort Services](/zh/docs/concepts/services-networking/service/)的默认端口范围。 所有默认端口都可以重新配置。当使用自定义的端口时，你需要打开这些端口来代替这里提到的默认端口。 一个常见的例子是 API 服务器的端口有时会配置为443。或者你也可以使用默认端口，把 API 服务器放到一个监听443 端口的负载均衡器后面，并且路由所有请求到 API 服务器的默认端口。 </ins>

Discussion:
Hi, I'm interested to translate the "Reference/Ports and Protocols" page. This is a Feature Request: translate en/docs/reference/ports-and- into Chinese. What would you like to be : zh/docs/reference/ports-and- /language zh /kind feature
