Ensuite, vers la fin du `Dockerfile`, nous copions tout le code. Comme c'est ce qui **change le plus fréquemment**, nous le plaçons vers la fin, car presque toujours, tout ce qui suit cette étape ne pourra pas utiliser le cache.

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

E o resto será manipulado pelo **FastAPI**.

Se você rodar a aplicação e ir até [http://localhost:8000/v1/](http://localhost:8000/v1/), você verá o retorno do Flask:

```txt
Hello, World from Flask!
```

E se você for até [http://localhost:8000/v2](http://localhost:8000/v2), você verá o retorno do FastAPI:

```JSON
