docker volume on docker-machine

[forrestzhang]

Is there any possible to add docker volume support? Is there any possible run cwl-runner on docker-machine or docker swarm?

$ cwl-runner docker.cwl docker-job.yml
/usr/local/bin/cwl-runner 1.0.20160331184641
I'm sorry, I couldn't load this CWL file, try again with --debug for more information.

$ docker-machine ls
