I’m not sure what you mean by me meaning “all containers all the time” I feel I
should rephrase my point:
- You should statically link your Python application so you have always full
control over your deployments.
- Don’t ship build tools to prod servers.
The way we can achieve that is by building virtualenvs on build servers. *How*
you get those virtualenvs to the deployments target I don’t care. Whether you
pex them or not, I don’t care either¹. I’ve used .debs with great success in
the past and I’m using Docker containers now (and so far we’re not out of
business :)).
I consider Linux distributions very nice build environments for my own
software. :) And there’s thing we totally don’t compile ourselves like
OpenSSL. It just doesn’t make any goddam sense to rely on the limited and
outdated offer of Python modules from your distribution. Even if they don’t
upgrade them under your butt and introduce regressions.

¹ For me apps always go to the same location so relocability is not an issue.
Contrary I’m not a super fan of having one opaque blob on server; the
transparent structure of a virtualenv is something I learned to appreciate.
