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)。

## 启动之前的步骤 { #previous-steps-before-starting }

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**。

因此，在启动应用程序之前，您将需要一个**单个进程**来执行这些**前面的步骤**。
