You've chosen a really bizarre way to package your software. I'm looking through your repo and can't see any code for your libraries. It seems like its somehow part of the docker image? So then this is just a shim for a docker environment that contains the code? Normally people would use Github for a hosted repo and make their software available on Pypi. But deploying with a docker file is kind of opaque and sketchy.

I would give better feedback but still no easy way to see the code? Unless you're trying to do it like this to have something like a closed-source version of your libraries... which would again be kind of a bizarre model to use with Python.
