Does not support non-default docker socket locations

[twigington]

The clusterdock.sh script assumes the docker socket location will be at /var/run/docker.sock on the host. It would be nice if the location could be pulled out of DOCKER_HOST or was configurable via an environment variable.

I worked around this by editing the clusterdock.sh file to reflect the location of the docker.sock file on my system.

Pull requests are welcome. That said, this project has evolved considerably in the last year (now hosted here) and we use the newer constructs in the Docker SDK for Python to abstract these issues away.
