    В ней будет создан файл `requirements.txt`

3. На этом шаге установите Poetry.

4. Скопируйте файлы `pyproject.toml` и `poetry.lock` в директорию `/tmp`.

    Поскольку название файла написано как `./poetry.lock*` (с `*` в конце), то ничего не сломается, если такой файл не будет найден.

5. Создайте файл `requirements.txt`.

    Aqui é onde geraremos o arquivo `requirements.txt`

3. Instale o Poetry nesse estágio do Docker.

4. Copie os arquivos `pyproject.toml` e `poetry.lock` para o diretório `/tmp`.

    Porque está usando `./poetry.lock*` (terminando com um `*`), não irá falhar se esse arquivo ainda não estiver disponível.

5. Gere o arquivo `requirements.txt`.
