The issue I'm trying to address here is that because of the Docker
volume, /builds/foo is really /var/lib/docker/volumes/123/_data/foo.
This causes some interesting issues with addressing files with Docker
from inside a Docker container. Do it just on ns4 (for now, if it works
and needed I may do it on host01 too). Also, deploy to the kodi host
last because it has issues right now.
