1. 這裡我們使用 `--workers` 命令列選項把 worker 數量設定為 4。

以下是一些合理的例子：

#### 簡單應用 { #a-simple-app }

如果你的應用「足夠簡單」，可以在「單一伺服器」而非叢集上執行，你可能會希望在容器內使用行程管理器。

#### Docker Compose { #docker-compose }

如果你部署到「單一伺服器」（非叢集），且使用「Docker Compose」，那麼你無法輕易（用 Docker Compose）在保有共用網路與「負載平衡」的同時管理容器複本。

那你可能會想要「單一容器」搭配「行程管理器」，在其中啟動「多個 worker 行程」。

重點是，這些「都不是」必須盲目遵守的「鐵律」。你可以用這些想法來「評估你的使用情境」，並決定對你的系統最好的做法，看看如何管理以下概念：

   * is defined as the function h such that {@code h(a) == g(f(a))} for each {@code a}.
   *
   * <p><b>JRE users and Android users who opt in to library desugaring:</b> use {@code
   * g.compose(f)} or (probably clearer) {@code f.andThen(g)} instead. Note that it is not
   * serializable.
   *
   * @param g the second function to apply
   * @param f the first function to apply

/**
 * Project scope.
 * Defines the type of source files to compile, usually either the one that compose the output package
 * (i.e. the <i>main</i> artifact) or the ones that will be used when building <i>tests</i>).
 * <p>
 * This extensible enum has two defined values, {@link #MAIN} and {@link #TEST},

### Docker

Proporcionamos imágenes de Docker en [ghcr.io](https://github.com/orgs/codelibs/packages). También proporcionamos un archivo Docker Compose (YAML) en [este repositorio](https://github.com/codelibs/docker-fess/tree/master/compose).

이는 `docker compose`를 사용할 때 꽤 눈에 띌 수 있습니다. 좀 더 기술적인 상세 내용은 Docker Compose FAQ 섹션을 참고하세요: [Why do my services take 10 seconds to recreate or stop?](https://docs.docker.com/compose/faq/#why-do-my-services-take-10-seconds-to-recreate-or-stop).

#### 디렉터리 구조 { #directory-structure }

이제 다음과 같은 디렉터리 구조가 되어야 합니다:

```
