* 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：

<div class="termy">

```console

        <!--<module name="WhitespaceAround">-->
            <!-- everything except { and } -->

# 第一步

最简单的 FastAPI 文件可能像下面这样：

{* ../../docs_src/first_steps/tutorial001.py *}

将其复制到 `main.py` 文件中。

运行实时服务器：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting development server 🚀

             Searching for package file structure from directories

## Check the automatic API docs { #check-the-automatic-api-docs }

Now, run your app:

<div class="termy">

```console
$ fastapi dev app/main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

And open the docs at <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

("className")}),c.getElementsByTagName=ib(function(a){return a.appendChild(e.createComment("")),!a.getElementsByTagName("*").length}),c.getElementsByClassName=$.test(e.getElementsByClassName)&&ib(function(a){return a.innerHTML="<div class='a'></div><div class='a i'></div>",a.firstChild.className="i",2===a.getElementsByClassName("i").length}),c.getById=ib(function(a){return o.appendChild(a).id=u,!e.getElementsByName||!e.getElementsByName(u).length}),c.getById?(d.find.ID=function(a,b){if(typeof b....

* FastAPI 이미지를 빌드합니다:

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>

/// tip | 팁

맨 끝에 있는 `.` 에 주목합시다. 이는 `./`와 동등하며, 도커에게 컨테이너 이미지를 빌드하기 위한 디렉터리를 알려줍니다.

이 경우에는 현재 디렉터리(`.`)와 같습니다.

///

### 도커 컨테이너 시작하기

* 여러분의 이미지에 기반하여 컨테이너를 실행합니다:

<div class="termy">

```console

 sourceSelector: '',\n  params: {},\n  trigger: SELECTOR_DATA_REFRESH,\n  content: '.card-body',\n  loadInContent: true,\n  loadOnInit: true,\n  loadErrorTemplate: true,\n  responseType: '',\n  overlayTemplate: '<div class=\"overlay\"><i class=\"fas fa-2x fa-sync-alt fa-spin\"></i></div>',\n  errorTemplate: '<span class=\"text-danger\"></span>',\n  onLoadStart() {},\n  onLoadDone(response) {\n    return response\n  },\n  onLoadFail(_jqXHR, _textStatus, _errorThrown) {}\n}\n\nclass CardRefresh {\n...

## Es in der automatischen API-Dokumentation testen { #check-the-automatic-api-docs }

Führen Sie nun Ihre App aus:

<div class="termy">

```console
$ fastapi dev app/main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## Проверка автоматической документации API { #check-the-automatic-api-docs }

Теперь запустите приложение:

<div class="termy">

```console
$ fastapi dev app/main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
