Using Linux containers has several advantages including **security**, **replicability**, **simplicity**, and others.

In a hurry and already know this stuff? Jump to the [`Dockerfile` below 👇](#build-a-docker-image-for-fastapi).

...and pass whatever that returns as the value of the dependency in our *path operation function* as the parameter `fixed_content_included`:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[22] *}

/// tip

All this might seem contrived. And it might not be very clear how is it useful yet.

These examples are intentionally simple, but show how it all works.

Usarlo en tu editor es lo que realmente te muestra los beneficios de FastAPI, al ver cuán poco código tienes que escribir, todos los chequeos de tipos, autocompletado, etc.

## Instalar FastAPI

El primer paso es instalar FastAPI.

Además, antes de eso, en versiones anteriores, el objeto `request` se pasaba como parte de los pares clave-valor en el contexto para Jinja2.

/// tip | Consejo

Al declarar `response_class=HTMLResponse`, la interfaz de usuario de la documentación podrá saber que el response será HTML.

///

/// note | Nota Técnica

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓

///

/// tip

This same technique applies to `Query`, `Cookie`, and `Header`. 😎

///

## Cookies with a Pydantic Model { #cookies-with-a-pydantic-model }

/// note | Нотатки

Це підтримується з версії FastAPI  `0.115.0`. 🤓

///

/// tip | Порада

Ця ж техніка застосовується до `Query`, `Cookie`, та `Header`. 😎

`Body` 또한 `FieldInfo`의 서브클래스 객체를 직접적으로 반환합니다. 그리고 `Body` 클래스의 서브클래스인 것들도 여러분이 나중에 보게될 것입니다.

 `Query`, `Path`와 그 외 것들을 `fastapi`에서 임포트할 때, 이는 실제로 특별한 클래스를 반환하는 함수인 것을 기억해 주세요.

///

/// tip | 팁

주목할 점은 타입, 기본 값 및 `Field`로 이루어진 각 모델 어트리뷰트가  `Path`, `Query`와 `Body`대신 `Field`를 사용하는 *경로 작동 함수*의 매개변수와 같은 구조를 가진다는 점 입니다.
