 TODO:
 _ Avoid having to change configuration manually
-_ Allow running artifact server with `-v $PWD:/opt/d4e/river'

 _ Let all components log to stdout to enable useful usage of `docker logs'
 _ Something better than setting framework and http-client to a branch
   explicitly in the Dockerfiles
