Celery worker and beat load in one command

Is there a way to start the celery worker and beat in one command? I would like to add celery to my automated deployment procedure with Fabric.

I am currently running:

celery -A prj worker -B

followed by

celery -A prj beat -l info -S django

However, the first command starts the worker and does not allow the next command (starting the beat) to be run because the worker start-up messages appear.

Is there a way to avoid the start-up messages appearing? Or do both of these actions in one command? Perhaps there is even a way to start these from my Django config?

Thanks!

Celery allows for you to run the worker and beat in the same process (mostly used for development purposes). Check out the help for celery worker:

> celery worker -h

...

Embedded Beat Options:
  -B, --beat            Also run the celery beat periodic task scheduler. Please note that there must only be
                        one instance of this service. .. note:: -B is meant to be used for development
                        purposes. For production environment, you need to start celery beat separately.
  -s SCHEDULE_FILENAME, --schedule-filename SCHEDULE_FILENAME, --schedule SCHEDULE_FILENAME
                        Path to the schedule database if running with the -B option. Defaults to celerybeat-
                        schedule. The extension ".db" may be appended to the filename. Apply optimization
                        profile. Supported: default, fair
  --scheduler SCHEDULER
                        Scheduler class to use. Default is celery.beat.PersistentScheduler

So the combined command, including your use of the django scheduler, would be the following:

celery -A prj worker --beat --scheduler django --loglevel=info
