Can't connect to docker from docker-compose

Question

I installed docker-machine 0.1.0 and docker-compose 1.1.0 on Mac OS 10.8.5.
Docker-machine is running normally and able to connect by docker-machine ssh.

Answer 1

logging out then in again helped me. In my case it was fresh install, I created a new user, new group then added the user to the docker group.

exit exit

then ssh into the server again
