Can I virtual env python-apps in production?

Upgrading projects are one the special projects to normal. To put what makes it so special is we don’t create a application architecture but we need to understand an existing one and think of ways of improvising it.

How about running production server in Python Virtual Environment?

You can create multiple instance of python like ++ python2 & python3 with multiple varieties of packages
Package interdependencies will be set clear
System packages

Can dockers replace python virtual env? Sorry, no. Virtualenv’s job isn’t just to separate your projects from each other. Its job is also to separate you from the operating system’s Python installation and the installed packages you probably have no idea about.

Should I use docker or python virtual env? You should use both at once, neither replaces the other:

Do isolate your application server’s OS from its host using Docker/lxc/jails/zones/kvm/VMware/… to one container/vm per application.
But inside of them also do isolate your Python environment using virtualenv from unexpected surprises in the system site-packages.

Overall I see a good advantage in running python application in virtual environment. What’s next is up to you now,. godspeed :) Source: https://www.reddit.com/r/Python/comments/2grmnn/virtualenv_on_production/ https://hynek.me/articles/virtualenv-lives/
