E se você precisar ter múltiplos workers, você pode simplesmente usar a opção de linha de comando `--workers`.

A imagem Docker foi criada quando o Uvicorn não suportava gerenciar e reiniciar workers mortos, então era necessário usar o Gunicorn com o Uvicorn, o que adicionava bastante complexidade, apenas para que o Gunicorn gerenciasse e reiniciasse os processos workers do Uvicorn.

And if you need to have multiple workers, you can simply use the `--workers` command line option.

/// note | Technical Details

The Docker image was created when Uvicorn didn't support managing and restarting dead workers, so it was needed to use Gunicorn with Uvicorn, which added quite some complexity, just to have Gunicorn manage and restart the Uvicorn worker processes.
