I'm trying to connect from inside a Docker container to a local Redis server on my machine. What I did so far:

* Redis is up an running on my machine (can connect to it via *redis-cli*)
* started an interactive Docker container (from the Ubuntu image)
* installed "redis-tool" inside the container
* tried to connect to Redis via redis-cli:  

> `redis-cli -h 172.17.0.3 -p 6379`  

(got the IP address via `ifconfig` inside the container)
* got an error saying "connection refused"

What's the trick I'm not thinking of in order to get a working connection?

I already tried to set "bind 0.0.0.0" in my `redis.conf` but that had no effect. I also tried to forward the port 6379 to 6379 when running the container but I get an error saying the address is already in use.

Thanks in advance!
