Hey Guys,

Im having some issus running a simple docker-compose app from the wiki.

docker-compse.yml

version: '2'
services:
  web:
    image: dockercloud/hello-world
  lb:
    image: dockercloud/haproxy
    links:
      - web
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

I think the problem has something to do with the version of your docker engine. It is too old for docker-py to connect to. You can either try it on a newer version of docker, or use docker compose v1 instead of v2.

@Numblesix

Currently, the latest version of docker 1.13. The docker coming with Fedora is far outdated. You can follow docs here to upgrade it: https://docs.docker.com/engine/installation/linux/fedora/

Issue was the version updated to the newest one and it works like a charm :)
