Docker / Celery / Django : Run a task with `celery` in a container while my `django` server is running in another container. It's possible?

I'm working on a project that uses Django, I'm a beginner with Django and Docker.

For a feature, I decided to create a task with Celery (the feature consist to create a matchmaking queue)

But, I use Docker for run my app, and I have 4 containers : one is for the frontend (node), the second for Django, the third is for my database PostgreSQL and the last is my redis server.

And I don't really know if it's necessary to create another container for Celery. I found nothing with my research about a thing like that, but (if I say nothing wrong) in theory, it's possible and even very good to create a container for Celery, it's logic.

So, I tried to launch my celery task in background, then launch my Django server like this in the same container :

$ celery -A backend worker -l INFO --detach
$ daphne -p 8000 backend.asgi:application

TWO PROBLEMS : We lose the whole point of using Docker doing this AND we can't see the logs of celery.

Problem : it is "ok" to do that, or it's really better to create another container for Celery or only for my task ? If yes, how I can do this ? I have really 0 idea how I can do that and what is the good option.

I invoke your help, please ! If it's necessary to share more context (my Dockerfiles, the docker-compose.yml, etc...), let me know that !

Thanks everyone in advance 😁 !
