In the next chapter about [FastAPI in Containers - Docker](docker.md){.internal-link target=_blank} I'll explain some strategies you could use to handle the other **deployment concepts**.

I'll show you how to **build your own image from scratch** to run a single Uvicorn process. It is a simple process and is probably what you would want to do when using a distributed container management system like **Kubernetes**.

## Recap

### Query-параметр со множеством значений по умолчанию

Вы также можете указать тип `list` со списком значений по умолчанию на случай, если вам их не предоставят:

 *  Fix: Don't crash loading the public suffix database in GraalVM native images. The function
    `HttpUrl.topPrivateDomain()` uses a resource file to identify private domains, but we didn't
    include this file on GraalVM.

* You can translate info boxes like `/// warning` with for example `/// warning | Achtung`. But do not change the word immediately after the `///`, it determines the color of the info box.

* Do not change the paths in links to images, code files, Markdown documents.

* However, when a Markdown document is translated, the `#hash-parts` in links to its headings may change. Update these links if possible.

### `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`；
