This document provides instructions for dockerizing a Django application with Postgres database. It discusses: 1) Creating a Dockerfile for the Django app and ensuring Postgres dependencies are installed. 2) Running Postgres in a container with environment variables for the database name, user, and password. 3) Configuring the Django settings to connect to the Postgres database using the environment variables. 4) Using docker-compose to define and run the Django and Postgres services on a bridge network, avoiding the need for links. The Django volume mounts the code directory for changes to be reflected.
