How to Set Environment Variables for a Python Django Application using Apache and mod_wsgi in Docker

This tutorial helps developers configure Python applications hosted with Apache and mod_wsgi running in Docker using environment variables for app configuration and secrets. It provides a step-by-step guide on how to achieve this, including the use of custom start scripts, Apache site configurations, and Dockerfiles. The tutorial covers both scenarios where Doppler is used to fetch secrets and when an `.env` file is used instead. With this knowledge, developers can now host their Python applications with Apache and mod_wsgi in Docker while keeping app configuration and secrets secure and well-organized.
