I've been trying to follow this thorough explanation on how to deploy a django app with celery worker to aws elastic beanstalk:
How to run a celery worker with Django app scalable by AWS Elastic Beanstalk?
I had some problems installing pycurl but solved it with the comment in:
Then i got:
[2019-01-26T06:43:04.865Z] INFO [12249] - [Application update app-190126_134200@28/AppDeployStage0/EbExtensionPostBuild/Infra-EmbeddedPostBuild/postbuild_1_raiseflags/Command 05_celery_tasks_run] : Activity execution failed, because: /usr/bin/env: bash
: No such file or directory
(ElasticBeanstalk::ExternalInvocationError)
But also solved it: it turns out I had to convert "celery_configuration.txt" file to UNIX EOL (i'm using Windows, and Notepad++ automatically converted it to Windows EOL).
With all these modifications I can successfully deploy the project. But the problem is that the periodic tasks are not running.
I get:

I also have this part of the logs:

I don't know if it has something to do with the error, but notice above the line [[ PATH="/opt/python/run/venv/bin/:%%(ENV_PATH)s" ]] --> shouldn't ENV_PATH be something else?:
environment=PYTHONPATH="/opt/python/current/app/:",PATH="/opt/python/run/venv/bin/:%%(ENV_PATH)s",RDS_PORT="5432",RDS_DB_NAME="ebdb",RDS_USERNAME="foobar",PYCURL_SSL_LIBRARY="nss",DJANGO_SETTINGS_MODULE="raiseflags.settings",RDS_PASSWORD="foobar",RDS_HOSTNAME="something.something.eu-west-1.rds.amazonaws.com"
I'ts my first time deploying an app with celery, and i'm really lost to be honest. I fought a lot to solve the first two errors (i'm really amateur), and now that i get this I don't even know where to start.
Also, i'm not sure if I'm using "celery_configuration.txt" the right way. The only thing I edited was the 2 places where it says "django_app", which I changed for "raiseflags" (the name of my django project). Is this correct?
Does anyone know how to solve it? I can paste my files if needed, but they are just like the ones provided in the first link. I'm using Windows.
Thank you very much!
Ok, the problem had nothing to do with the PATH line I was referring to. I just had to add 'django_celery_beat' and 'django_celery_results' in INSTALLED_APPS in my settings.py
The connection error I later referred to talking to Fran was because I needed to set BROKER_URL instead of CELERY_BROKER_URL, also in the settings.py file. I guess this had to do with me not specifying 'CELERY' as the namespace in the app.autodiscover_tasks() in celery.py file (although in the linked question they do it, i didn't do it because i was using a different version of celery).
Thanks to Fran for everything, specially for pointing out that i should review the celery error logs. I didn't know how to do it. If any other amateur is also struggling, know that you have to "eb ssh" to your instance and then "tail -n 40 /var/log/celery-worker.log" and ""tail -n 40 /var/log/celery-beat.log" (where "40" is the number of lines you want to read). I know this sounds obvious to a lot of people but, stupid me, I had no clue.
(btw, i'm still struggling with a problem with the celery worker, that can't find pycurl module, but this has nothing to do with this question).
