Si estás usando contenedores, por ejemplo con Docker o Kubernetes, te contaré más sobre eso en el próximo capítulo: [FastAPI en Contenedores - Docker](docker.md){.internal-link target=_blank}.

En particular, cuando corras en **Kubernetes** probablemente **no** querrás usar workers y en cambio correr **un solo proceso de Uvicorn por contenedor**, pero te contaré sobre eso más adelante en ese capítulo.

## Múltiples Workers

# Debugging { #debugging }

You can connect the debugger in your editor, for example with Visual Studio Code or PyCharm.

## Call `uvicorn` { #call-uvicorn }

In your FastAPI application, import and run `uvicorn` directly:
