Problem : I installed the docker-machine 0.1.0 and docker-compose 1.1.0 on the Mac OS 10.8.5. Docker-machine is running normally and able to connect by the docker-machine ssh. But can't connect from docker-compose getting following error: $ docker-compose up ... running? If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable. Why can't I connect? Any clues?
