ConnectionError: Error -3 connecting to redis:6379. Try again - docker

Question

I cannot connect redis client in a docker container with custom redis.conf file. Also even if i remove the code for connect redis with custom redis.conf file docker will still attempt to connect to custom redis file.
Docker.compose.yml
version: '2'
services:
data:
environment:
- RHOST=redis
command: echo true
networks:
- redis-net
depends_on:
- redis
redis:
image: redis:latest
build:
context: .
dockerfile: Dockerfile_redis
ports:
- "6379:6379"
command: redis-server /etc/redis/redis.conf
volumes:
- ./redis.conf:/etc/redis/redis.conf
networks:
redis-net:
volumes:
redis-data:
Dockerfile_redis
FROM redis:latest
COPY redis.conf /etc/redis/redis.conf
CMD [ "redis-server", "/etc/redis/redis.conf" ]
This is where i connect to redis. I use requirepass in redis.conf file.
redis_client = redis.Redis(host='redis',password='password1')
Is there a way to find out original redis.conf file that docker uses so then i could just change password to make redis secure ? I just use original redis.conf file which comes after installation of redis to server with "apt install redis" then i change requirepass.

I have fixed this issue finally with help of https://github.com/sameersbn/docker-redis.
There are no need to use dockerfile for redis in this case.
Docker.compose.yml:
version: '2'
services:
data:
command: echo true
environment:
- RHOST=Redis
depends_on:
- Redis
Redis:
image: sameersbn/redis:latest
ports:
- "6379:6379"
environment:
- REDIS_PASSWORD=changeit
volumes:
- /srv/docker/redis:/var/lib/redis
restart: always
redis_connect.py
redis_client = redis.Redis(host='Redis',port=6379,password='changeit')
