+启用这些[必要的端口](/zh/docs/reference/ports-and-protocols/)后才能使 Kubernetes 的各组件相互通信。可以使用 telnet 来检查端口是否启用，例如：

-
-Any port numbers marked with * are overridable, so you will need to ensure any
-custom ports you provide are also open.
-
-Although etcd ports are included in control-plane nodes, you can also host your own
-etcd cluster externally or on custom ports.
-
-The pod network plugin you use (see below) may also require certain ports to be
-open. Since this differs with each pod network plugin, please see the
-documentation for the plugins about what port(s) those need.

-使用 * 标记的任意端口号都可以被覆盖，所以你需要保证所定制的端口是开放的。

-虽然控制平面节点已经包含了 etcd 的端口，你也可以使用自定义的外部 etcd 集群，或是指定自定义端口。

-你使用的 Pod 网络插件 (见下) 也可能需要某些特定端口开启。由于各个 Pod 网络插件都有所不同，
