Docker-compose , anyway to specify a redis.conf file?

Question

my redis container is defined as he standard image in my docker_compose.yml

redis:  
  image: redis
  ports:
    - "6379"

I guess it's using standard settings like binding to Redis at localhost I need to bind it to 0.0.0.0, is there anyway to add a local redis.conf file to change the binding and let docker-compose knows it?

thanks for any trick...

Answer 1

Yes. Just mount your redis.conf over the default with a volume:

redis:  
  image: redis
  volumes:
    - ./redis.conf:/usr/local/etc/redis/redis.conf
  ports:
    - "6379"

Alternatively, create a new image based on the redis image with your conf file copied in. Full instructions are at: https://registry.hub.docker.com/_/redis/

However, the redis image does bind to 0.0.0.0 by default. To access it from the host, you need to use the port that Docker has mapped to the host for you which you find by using docker ps or the docker port command, you can then access it at localhost:32678 where 32678 is the mapped port. Alternatively, you can specify a specific port to map to in the docker-compose.yml.

As you seem to be new to Docker, this might all make a bit more sense if you start by using raw Docker commands rather than starting with Compose.
