Ten years ago, almost to the day, I wrote a very long blog post titled Deploying Python Web Applications with nginx and uWSGI Emperor. This week, I’ve migrated the Python web applications hosted on my VPS to Docker containers. Here are some reasons why, and all my Docker files to help you do this on your server.
I’ve recently migrated my VPS from Fedora to Ubuntu. Here’s a list of things that might be useful to keep in mind before, during, and after a migration of a server that hosts publicly accessible Web sites and applications, as well as other personal services, and how to get rid of the most annoying parts of Ubuntu.
You’ve just written a great Python web application. Now, you want to share it with the world. In order to do that, you need a server, and some software to do that for you.
The following is a comprehensive guide on how to accomplish that, on multiple Linux-based operating systems, using nginx and uWSGI Emperor. It doesn’t force you to use any specific web framework — Flask, Django, Pyramid, Bottle will all work. Written for Ubuntu, Debian, Fedora, CentOS 7, Alma Linux, Rocky Linux and Arch Linux (should be helpful for other systems, too). Now with an Ansible Playbook.
Revision 8 (2022-02-20): works with Fedora 35, AlmaLinux 8, RockyLinux 8
While this guide is still valid, in 2026 I switched to Docker and Gunicorn for my Python web app deployments. Check out `Deploying Python Web Applications with Docker`_ for more details.
I spent Saturday on rewriting a Flask app in Django. The app in question was Nikola Users, which is a very simple CRUD app. And yet, the Flask code was a mess, full of bugs and vulnerabilities. Eight hours later, I had a fully functional Django app that did more and fixed all problems.
