I\'m having application built using celery and recently we got a requirement to run certain tasks on schedule.
I think celerybeat is perfect for this, but I got few ques
To answer your 2 questions:
If you run several celerybeat instances you get duplicated tasks, so afaik you should have only single celerybeat instance.
I'm using supervisord
as you mentioned to run celery workers and celerybeat workers as deamon so they should always be up & running.
my supervisord config:
[program:my_regular_worker]
command=python2.7 /home/ubuntu/workspace/src/manage.py celery worker -Q my_regular_worker-queue_name -c 1 -l info --without-mingle
process_name=my_regular_worker
directory=/home/ubuntu/workspace/src
autostart=true
autorestart=true
user=ubuntu
stdout_logfile=/tmp/my_regular_worker.log
redirect_stderr=true
[program:my_celerybeat_worker]
command=python2.7 /home/ubuntu/workspace/src/manage.py celery worker -Q my_celerybeat_worker-queue_name -c 1 -l info --without-mingle -B -s /tmp/celerybeat-schedule
