Agregué fastapi a un contenedor docker que realiza tareas en segundo plano usando BackgroundTask de fastapi. Cuando ejecuto el contenedor, la página no se carga y he visto este error en los registros del escritorio de la ventana acoplable gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3> . Estoy usando docker run -d --name mycontainer -p 8080:8080 onetest para ejecutar el contenedor.

entrypoint.sh

 #!/bin/bash gunicorn --worker-tmp-dir /dev/shm --config gunicorn.config.py app.main:app
