### Dependency injection

FastAPI'ın inanılmaz derecede kullanımı kolay, fakat inanılmaz derecede güçlü <abbr title='"components", "resources", "services", "providers" olarak da bilinen'><strong>Dependency Injection </strong></abbr> sistemi var.

* Dependencylerin bile dependencies'i olabiliyor, FastAPI bunun  için **graph of "dependency"** yaratıyor.
* Hepsi **otomatik olarak** FastAPI tarafından hallediliyor.

### 单独的程序

为了实现这一点，您通常会有一个**单独的程序**来确保您的应用程序在启动时运行。 在许多情况下，它还可以确保其他组件或应用程序也运行，例如数据库。

### 启动时运行的示例工具

可以完成这项工作的工具的一些示例是：

* Docker
* Kubernetes
* Docker Compose
* Docker in Swarm Mode
* Systemd
* Supervisor
* 作为其服务的一部分由云提供商内部处理
* 其他的...

我将在接下来的章节中为您提供更具体的示例。


## 重新启动

与确保应用程序在启动时运行类似，您可能还想确保它在挂掉后**重新启动**。

### 我们会犯错误

作为人类，我们总是会犯**错误**。 软件几乎*总是*在不同的地方隐藏着**bug**。 🐛

### Beispieltools zur Ausführung beim Hochfahren

Einige Beispiele für Tools, die diese Aufgabe übernehmen können, sind:

* Docker
* Kubernetes
* Docker Compose
* Docker im Schwarm-Modus
* Systemd
* Supervisor
* Es wird intern von einem Cloud-Anbieter im Rahmen seiner Dienste verwaltet
* Andere ...

In den nächsten Kapiteln werde ich Ihnen konkretere Beispiele geben.

/**

Also, depending on your operating system (e.g. Linux, Windows, macOS), it could have come with Python already installed. And in that case it probably had some packages pre-installed with some specific versions **needed by your system**. If you install packages in the global Python environment, you could end up **breaking** some of the programs that came with your operating system.
