Need to set CELERY_BROKER_URL
The example production env file states the following:
# If you want to use Redis over unix sockets, you'll actually need two variables:
# For the cache part:
# CACHE_URL=redis:///run/redis/redis.sock?db=0
# For the Celery/asynchronous tasks part:
# CELERY_BROKER_URL=redis+socket:///run/redis/redis.sock?virtual_host=0
When testing I found that even if I set CACHE_URL
the CELERY_BROKER_URL
was set to redis://redis:6379/0
(not by me). I think a solution would be to explicitly state that a user needs to set both variables
Sorry for the quick writup, I am short on time and happy to explain further if the issues is unclear
