Live Coding an Update to My Build a SAAS App with Flask Course

In this 25 minute video we go over updating Postgres, Redis, Python, Node, a bunch of Python packages and adding Hadolint.

I recently added an update to my https://buildasaasappwithflask.com course and decided to publish that update video publicly. It demonstrates the process of maintaining and updating a real world application.
