Running Locally - Celery/RabbitMQ/Redis

[txmxthy]

Hi, I am learning all of these tools at once with this project so I don't have a lot of background knowledge on this stuff.

I've followed along through the bootstrap instructions for non-docker setup all the way down to running - I encounter issues around using celery. My env looks like this: I chose sqlite as the db and un-commented it.

DJANGO_SETTINGS_MODULE=tempest.settings.local
CELERY_BROKER_URL=amqp://broker:5672//
REDIS_URL=redis://result:6379
# Please choose postgres or sqlite as your DB:
# DATABASE_URL=postgres://tempest:password@db:5432/tempest
DATABASE_URL=sqlite:///db.sqlite3

Running the worker: poetry run celery --app=tempest worker --loglevel=info

but we get this response: ERROR/MainProcess] consumer: Cannot connect to amqp://guest:**@127.0.0.1:5672//: [WinError 10061] No connection could be made because the target machine actively refused it. I've been looking through the celery docs and I assume this project uses redis instead of rabbitmq which that CELERY_BROKER_URL port in the env is set up for (5672) and that the celery broker url needs to be changed?

Figured if I am encountering it future people might too and it might be worth an update to the instructions if something does need to be changed? Any help is appreciated!

Yes, that's right. You need to change CELERY_BROKER_URL to point to redis, as you're not using Docker. Try something like CELERY_BROKER_URL=redis://broker:6379. Let me know if this or something else works for you.

If you can contribute, please open a PR updating the Setup Redis step of README explaining that.

I was able to get it working by adding CELERY_BROKER_URL = config("CELERY_BROKER_URL", default="redis://localhost:6379/0")

into my local_base.py as well as making those changes. I can make a PR but not sure if that is a suitable fix for everyone? It feels out of place there.

I would say the best PR here is to fix the Setup Redis section of README to explain you need to set CELERY_BROKER_URL in .env to the Redis URL.
