Here are some possible ideas:

* An "Init Container" in Kubernetes that runs before your app container
* A bash script that runs the previous steps and then starts your application
    * You would still need a way to start/restart *that* bash script, detect errors, etc.

!!! tip

This is the basic idea. But you will probably want to take care of some additional things, like:

* Security - HTTPS
* Running on startup
* Restarts
* Replication (the number of processes running)
* Memory
* Previous steps before starting

From the list of deployment concepts from above, using workers would mainly help with the **replication** part, and a little bit with the **restarts**, but you still need to take care of the others:

* **Security - HTTPS**
* **Running on startup**
* ***Restarts***
* Replication (the number of processes running)
* **Memory**
* **Previous steps before starting**

## Containers and Docker

## Running on Startup and Restarts

There is normally another tool in charge of **starting and running** your container.

It could be **Docker** directly, **Docker Compose**, **Kubernetes**, a **cloud service**, etc.

In most (or all) cases, there's a simple option to enable running the container on startup and enabling restarts on failures. For example, in Docker, it's the command line option `--restart`.

    E.g. `pip install httpx`.

Import `TestClient`.

Create a `TestClient` by passing your **FastAPI** application to it.

Create functions with a name that starts with `test_` (this is standard `pytest` conventions).

Use the `TestClient` object the same way as you do with `httpx`.

В большинстве случаев это простейшие настройки запуска и перезагрузки приложения (при падении). Например, команде запуска Docker-контейнера можно добавить опцию `--restart`.

Управление запуском и перезагрузкой приложений без использования контейнеров - весьма затруднительно. Но при **работе с контейнерами** - это всего лишь функционал доступный по умолчанию. ✨

!!! note
    Notice the header `Authorization`, with a value that starts with `Bearer `.

## Advanced usage with `scopes`

OAuth2 has the notion of "scopes".

You can use them to add a specific set of permissions to a JWT token.

여러분의 컨테이너를 **시작하고 실행하는** 데에 일반적으로 사용되는 도구는 따로 있습니다.

이는 **도커** 자체일 수도 있고, **도커 컴포즈**, **쿠버네티스**, **클라우드 서비스** 등이 될 수 있습니다.

대부분 (또는 전체) 경우에, 컨테이너를 구동하거나 고장시에 재시작하도록 하는 간단한 옵션이 있습니다. 예를 들어, 도커에서는, 커맨드 라인 옵션 `--restart` 입니다.

컨테이너를 사용하지 않고서는, 어플리케이션을 구동하고 재시작하는 것이 매우 번거롭고 어려울 수 있습니다. 하지만 **컨테이너를 사용한다면** 대부분의 경우에 이런 기능은 기본적으로 포함되어 있습니다. ✨

## 복제 - 프로세스 개수

Das ist die Grundidee. Aber Sie möchten sich wahrscheinlich um einige zusätzliche Dinge kümmern, wie zum Beispiel:

* Sicherheit – HTTPS
* Beim Hochfahren ausführen
* Neustarts
* Replikation (die Anzahl der laufenden Prozesse)
* Arbeitsspeicher
* Schritte vor dem Start
