After upgrading to docker 1.8.2, when the container is first created its NetworkMode is empty. Only after starting does it get its value. I'm assuming both this and #23 are due to the network system changes, not sure if this is a docker bug, or if we should check for "" NetworkMode. In my fork, i changed connectable to detect "start" instead of "create" which fixes this bug, and has the advantage of working through container restarts.
