"_Honestly, what you've built looks super solid and polished. In many ways, it's what I wanted **Hug** to be - it's really inspiring to see someone build that._"

Bauen Sie dazu zunächst die gesamte Dokumentation:

<div class="termy">

```console
// Verwenden Sie das Kommando „build-all“, das wird ein wenig dauern
$ python ./scripts/docs.py build-all

Building docs for: en
Building docs for: es
Successfully built docs for: es
```

</div>

That documentation will show up in the Swagger UI at `/docs` in your API, and it will let external developers know how to build the *external API*.

This example doesn't implement the callback itself (that could be just a line of code), only the documentation part.

!!! tip
    The actual callback is just an HTTP request.

```Dockerfile
COPY ./app /code/app
```

### 构建 Docker 镜像

现在所有文件都已就位，让我们构建容器镜像。

* 转到项目目录（在`Dockerfile`所在的位置，包含`app`目录）。
* 构建你的 FastAPI 镜像：


<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>


!!! tip
    注意最后的 `.`，它相当于`./`，它告诉 Docker 用于构建容器镜像的目录。

    在本例中，它是相同的当前目录（`.`）。

### 启动 Docker 容器

* 根据你的镜像运行容器：
