Quando você executa **vários processos** do mesmo programa de API, eles são comumente chamados de **trabalhadores**.

### Processos do Trabalhador e Portas { #worker-processes-and-ports }

Lembra da documentação [Sobre HTTPS](https.md) que diz que apenas um processo pode escutar em uma combinação de porta e endereço IP em um servidor?

Isso ainda é verdade.

  that prevented the control plane's pod garbage collector from deleting pods that contained duplicated field keys (env. variables with repeated keys or container ports). ([#121380](https://github.com/kubernetes/kubernetes/pull/121380), [@mimowo](https://github.com/mimowo)) [SIG Apps, Auth, Scheduling and Testing]

- Kube-proxy will no longer hold service node ports open on the node. Users are still advised not to run any listener on node ports range used by kube-proxy. ([#108496](https://github.com/kubernetes/kubernetes/pull/108496), [@khenidak](https://github.com/khenidak))

* Azure: Fix support for multiple `loadBalancerSourceRanges`, and add support for UDP ports and the Service spec's `sessionAffinity`. ([#45523](https://github.com/kubernetes/kubernetes/pull/45523), [@colemickens](https://github.com/colemickens))

* Fix an issue where port forwarding doesn't forward local TCP6 ports to the pod ([#57457](https://github.com/kubernetes/kubernetes/pull/57457), [@vfreex](https://github.com/vfreex))

  by default, that prevented the control plane's pod garbage collector from deleting
  pods that contained duplicated field keys (environmental variables with repeated keys or
  container ports). ([#121103](https://github.com/kubernetes/kubernetes/pull/121103), [@mimowo](https://github.com/mimowo))

- The maximum number of ports allowed in EndpointSlices has been increased from 100 to 20,000 ([#99795](https://github.com/kubernetes/kubernetes/pull/99795), [@robscott](https://github.com/robscott)) [SIG Network]

同じAPIプログラムの**複数のプロセス**を実行する場合、それらは一般的に**Worker／ワーカー**と呼ばれます。

### ワーカー・プロセス と ポート { #worker-processes-and-ports }

[HTTPSについて](https.md)のドキュメントで、1つのサーバーで1つのポートとIPアドレスの組み合わせでリッスンできるのは1つのプロセスだけであることを覚えていますでしょうか？

これはいまだに同じです。

そのため、**複数のプロセス**を同時に持つには**ポートでリッスンしている単一のプロセス**が必要であり、それが何らかの方法で各ワーカー・プロセスに通信を送信することが求められます。
