I ran a redis container with the following command:

docker run  --name redis_env --hostname redis \
            -p 6379:6379 \
            -v $PWD/DBVOL/redis/data:/data:rw \
            --privileged=true \
            -d redis redis-server

I successfully linked to the Redis server using Redis Desktop Manager locally, but when I built a distributed crawler using scrapy-redis according to the documentation, I got an error message rejecting the connection:

my settings.py is configured as:

>>> import redis
>>> redis.connection("redis://localhost:6379/0")
Connection<host=redis://localhost:6379/0,port=6379,db=0>

what is the reason for this? How to solve? Please don"t hesitate to give us your advice, thank you!
