How can I connect from Django to Docker Redis Container using BackgroundScheduler? - django

Question

I am currently working on a Django project, which is supposed to send messages to a mobile app via websockets. For the Django project I used Docker to put it online. Now I want to send planned messages for the first time, for this I use Apscheduler or django-apscheduler. I try to save the jobs in my Redis container. But for some reason the connection is denied. Am I basically doing something wrong or does it hang somewhere?
Dockerfile:

jobs.py (trying connect to redis), I have already tried 0.0.0.0, localhost, redis://redis for the "host"
jobstores = {
'default': RedisJobStore(jobs_key='dispatched_trips_jobs', run_times_key='dispatched_trips_running', host='redis', port=6380)
}
executors = {
'default': ThreadPoolExecutor(20),
'processpool': ProcessPoolExecutor(5)
}
job_defaults = {
'coalesce': False,
'max_instances': 3
}
#jobStore.remove_all_jobs()
scheduler = BackgroundScheduler(jobstores=jobstores, executors=executors, job_defaults=job_defaults)
register_events(scheduler)
scheduler.start()
print("Scheduler started!")
Error (appears multiple times)
