Ich werde Ihnen in einem zukünftigen Kapitel mehr über Container-Images, Docker, Kubernetes, usw. erzählen: [FastAPI in Containern – Docker](docker.md){.internal-link target=_blank}.

## Schritte vor dem Start

Es gibt viele Fälle, in denen Sie, **bevor Sie Ihre Anwendung starten**, einige Schritte ausführen möchten.

---

Exemplos comuns de limite de CPU são coisas que exigem processamento matemático complexo.

Por exemplo:

* **Processamento de áudio** ou **imagem**
* **Visão do Computador**: uma imagem é composta por milhões de pixels, cada pixel tem 3 valores (cores, processamento que normalmente exige alguma computação em todos esses pixels ao mesmo tempo)

리눅스 컨테이너를 사용하는 데에는 **보안**, **반복 가능성**, **단순함** 등의 장점이 있습니다.

!!! tip "팁"
    시간에 쫓기고 있고 이미 이런것들을 알고 있다면 [`Dockerfile`👇](#build-a-docker-image-for-fastapi)로 점프할 수 있습니다.

<details>
<summary>도커파일 미리보기 👀</summary>

```Dockerfile
FROM python:3.9

WORKDIR /code

COPY ./requirements.txt /code/requirements.txt

### `UploadFile`

`UploadFile` 的属性如下：

* `filename`：上传文件名字符串（`str`），例如， `myimage.jpg`；
* `content_type`：内容类型（MIME 类型 / 媒体类型）字符串（`str`），例如，`image/jpeg`；

`UploadFile` имеет следующие атрибуты:

* `filename`: Строка `str` с исходным именем файла, который был загружен (например, `myimage.jpg`).
* `content_type`: Строка `str` с типом содержимого (MIME type / media type) (например, `image/jpeg`).

```

対話的ドキュメントでは非推奨と明記されます:

*path operations*が非推奨である場合とそうでない場合でどのように見えるかを確認してください:

You can type messages in the input box, and send them:

<img src="/img/tutorial/websockets/image02.png">

And your **FastAPI** application with WebSockets will respond back:

You can send (and receive) many messages:
