Of course you can just build the venv on your build server without wheeling up a temporary container and then package it using Docker or DEB or whatever.  You should be separating building and running anyway so Python – as much as I’d like Go-style single binaries too – is in no way special here.  The nice thing about temporary containers though is that I can do all of that on my Mac.

I thought I pointed that out in my very first sentence. :D

What I don't quite understand is how people can be in love with Go’s static linking but complaining about Virtualenvs in deployments.   Unwieldy as virtualenvs are: *for Python code* they are exactly that: statically linked build artifacts.  The principles are very similar, the execution is arguably better for Go.
