How to kill airflow worker properly (with celery executor)?

Question

I can start an "airflow worker" (with a celery executor) but I don't know how to kill it properly. I have the impression that many subprocesses are created and I don't know how to shut them gracefully.

Thanks in advance.

Answer 1

I normally set up the Airflow processes as systemd processes and just run systemctl stop airflow-* however I think you can simply kill the main airflow-worker process with a standard linux kill command? Probably what the systemd daemon does anyway.

Answer 2

To stop a worker running on a machine you can use:

airflow celery stop
