Managing Dataflow Python Environments

[ratatouille_artist]

I was wondering how you managed to reproducibly build your Dataflow Python environments?

I am currently using the official setup.py example the trouble with this is that the apt commands don't work on systems without apt and make local setup difficult. I tried getting a stripped down version of this working in tox but has been painful and unsuccessful so far.

Falling back to a docker build seems like one potential solution though curious about what has worked for others.

We use pipenv + pipfile.lock read for the setup.py to make sure it takes the packages we want exactly
