I keep on getting the error message: redis.exceptions.ResponseError: NOAUTH Authentication required.. (I'm using celery to perform background tasks).

My settings.py looks like this:

CELERY_BROKER_URL = 'redis://user:my_strong_password@'+REDIS_IP+':6379/0'
the docker-compose I have:
services:
  redis:
    image: redis:latest
    container_name: jh_redis
    ports:
     - '6379:6379'
    command: redis-server --appendonly yes --requirepass my_strong_password 
you can see that my attempt to provide the password (--requirepass) is exactly as it shown in the settings.py however, while the docker is up and running I still get the subject error message. 
I have tried different combination such as:
--requirepass user:my_strong_password 
but still didn't work.
Note: when I take off the entire command line - it works (but 32 hours after - I get the error message and it stop working).
What should be the appropriate settings in docker-compose to have it work smoothly? 
                Your Redis server is exposed to the public network and is being connected to by someone who sets a password on the instance at least, if not something worse. Secure your Redis with a password at the very least, if not disconnect it from the world, to reduce the threat.

                @ItamarHaber thanks. Could you share how you secure it on docker? I'm still straggling with the syntax.

According to the celery docs, your broker url should be in this format:
redis://:password@hostname:port/db_number
i.e., you should remove user from the broker_url.
                I haven't forgotten your answer! For some reason it takes few days to see if it works not (on the server side). I just revised it based on your strategy and let's see if it can last more then 4 days. Position and hold. Thanks again
