Para lograr eso, importa `JSONResponse`, y devuelve tu contenido allí directamente, configurando el `status_code` que deseas:

### Contêiner Único { #single-container }

Se você tiver uma configuração simples, com um **único contêiner** que então inicia vários **processos workers** (ou também apenas um processo), então poderia executar esses passos anteriores no mesmo contêiner, logo antes de iniciar o processo com o aplicativo.
