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：

import org.apache.maven.api.annotations.Immutable;

import static org.apache.maven.api.ExtensibleEnums.projectScope;

/**
 * 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

We provide Docker images on [ghcr.io](https://github.com/orgs/codelibs/packages). We also provide a Docker Compose (YAML) file in [this repository](https://github.com/codelibs/docker-fess/tree/master/compose).

For a quick installation, docker-compose reference configs are also available on the [Keycloak GitHub](https://github.com/keycloak/keycloak-containers/tree/main/docker-compose-examples).

### Configure Keycloak Realm

- Go to Clients
  - Click on account
    - Settings
    - Change `Access Type` to `confidential`.

詳細については、[インストールガイド](https://fess.codelibs.org/15.3/install/index.html)を参照してください。

### Docker

[ghcr.io](https://github.com/orgs/codelibs/packages)にDockerイメージを提供しています。また、このリポジトリにはDocker Compose（YAML）ファイルも用意されています。[こちらのリポジトリ](https://github.com/codelibs/docker-fess/tree/master/compose)で確認できます。

## Prerequisites

Configure and install casdoor server by following [Casdoor Server Installation](https://casdoor.org/docs/basic/server-installation).
For a quick installation, docker-compose reference configs are also available on the [Casdoor Try with Docker](https://casdoor.org/docs/basic/try-with-docker).

### Configure Casdoor

- Go to Applications
  - Create or use an existing Casdoor application
