## コンテナ・イメージ

Dockerは、**コンテナ・イメージ**と**コンテナ**を作成・管理するための主要なツールの1つです。

そして、DockerにはDockerイメージ（コンテナ）を共有する<a href="https://hub.docker.com/" class="external-link" target="_blank">Docker Hub</a>というものがあります。

Docker Hubは 多くのツールや環境、データベース、アプリケーションに対応している予め作成された**公式のコンテナ・イメージ**をパブリックに提供しています。

例えば、公式イメージの1つに<a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Python Image</a>があります。

* **云服务** 为您处理此问题
     * 云服务可能**为您处理复制**。 它可能会让您定义 **要运行的进程**，或要使用的 **容器映像**，在任何情况下，它很可能是 **单个 Uvicorn 进程**，并且云服务将负责复制它。

     如果这些关于 **容器**、Docker 或 Kubernetes 的内容还没有多大意义，请不要担心。

     我将在以后的章节中向您详细介绍容器镜像、Docker、Kubernetes 等：[容器中的 FastAPI - Docker](docker.md){.internal-link target=_blank}。

## 启动之前的步骤

在很多情况下，您希望在**启动**应用程序之前执行一些步骤。

例如，您可能想要运行**数据库迁移**。

但在大多数情况下，您只想执行这些步骤**一次**。
