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

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

### 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：

      for (Class<?> param : method.getParameterTypes()) {
        signature.append(sep).append(typeName(param));
        sep = ", ";
      }
      methods.add(signature.append(")").toString());
    }
    return methods.build();
  }

  private static String typeName(Class<?> type) {
    return type.isArray() ? typeName(type.getComponentType()) + "[]" : type.getName();
  }
