I think that one of the hidden points in there is that you do not really need a container to deploy python wsgi application, you need an venv and few system packages. Doing that by means of ansible playbook or even manually preinstalled system image that you just clone and then just only use Python packaging mechanisms is even somewhat simpler and faster than building container that works (ie. take a VM, poke into it until it works and then just clone it, deployment of your application is decoupled from the underlying OS)
