## 为 FastAPI 构建 Docker 镜像

好吧，让我们现在构建一些东西！ 🚀

我将向你展示如何基于 **官方 Python** 镜像 **从头开始** 为 FastAPI 构建 **Docker 镜像**。

这是你在**大多数情况**下想要做的，例如：

* 使用 **Kubernetes** 或类似工具
* 在 **Raspberry Pi** 上运行时
* 使用可为你运行容器镜像的云服务等。

### 依赖项

你通常会在某个文件中包含应用程序的**依赖项**。

具体做法取决于你**安装**这些依赖时所使用的工具。

最常见的方法是创建一个`requirements.txt`文件，其中每行包含一个包名称和它的版本。

## Build a Docker Image for FastAPI

ということで、何か作りましょう！🚀

FastAPI用の**Dockerイメージ**を、**公式Python**イメージに基づいて**ゼロから**ビルドする方法をお見せします。

これは**ほとんどの場合**にやりたいことです。例えば：

* **Kubernetes**または同様のツールを使用する場合
* **Raspberry Pi**で実行する場合
* コンテナ・イメージを実行してくれるクラウド・サービスなどを利用する場合

### パッケージ要件（package requirements）

アプリケーションの**パッケージ要件**は通常、何らかのファイルに記述されているはずです。

パッケージ要件は主に**インストール**するために使用するツールに依存するでしょう。

constant, even if the literal's fractional part is zero.
