Make sure you have the latest pip version on your local environment to avoid errors on the next steps:

<div class="termy">

```console
$ python -m pip install --upgrade pip

---> 100%
```

</div>

!!! tip
    Every time you install a new package with `pip` under that environment, activate the environment again.

### 🐖

    Wenn Sie eine ältere Version haben, werden Sie Fehler angezeigt bekommen, wenn Sie versuchen, `Annotated` zu verwenden.

    Bitte [aktualisieren Sie FastAPI](../deployment/versions.md#upgrade-der-fastapi-versionen){.internal-link target=_blank} daher mindestens zu Version 0.95.1, bevor Sie `Annotated` verwenden.

## Metadaten deklarieren

```Dockerfile
FROM python:3.9

WORKDIR /code

COPY ./requirements.txt /code/requirements.txt

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

COPY ./app /code/app

CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "80"]

# If running behind a proxy like Nginx or Traefik add --proxy-headers

    !!! note
        The `--no-cache-dir` is only related to `pip`, it has nothing to do with Docker or containers.

    The `--upgrade` option tells `pip` to upgrade the packages if they are already installed.

    Because the previous step copying the file could be detected by the **Docker cache**, this step will also **use the Docker cache** when available.

Com o **FastAPI** é muito fácil (graças ao Starlette), verifique a documentação: [Testando](tutorial/testing.md){.internal-link target=_blank}

Após você ter os testes, então você pode fazer o _upgrade_ da versão **FastAPI** para uma mais recente, e ter certeza que todo seu código esteja funcionando corretamente rodando seus testes.
