Configuring Rails and Postgres with Docker Compose

Getting a Rails application to communicate reliably with a PostgreSQL database inside containerized environments can be tricky when starting out. Managing database readiness, environment variables, and clean server restarts is essential for a smooth development workflow. This course teaches you how to orchestrate your Rails and Postgres services using Docker Compose. You will gain a solid understanding of container networks, environment configuration, and how to safely restart your Rails server without losing database integrity. What you'll learn: - Understand the foundational concepts of containerizing Rails applications and PostgreSQL databases. - Configure Docker Compose files to define services, networks, and persistent volumes. - Manage environment variables securely using modern Rails configuration patterns. - Implement database health checks to ensure Postgres is fully ready before Rails attempts to connect. - Apply clean restart commands to update your Rails server during active development. - Create and migrate your PostgreSQL database within a containerized environment. You will start with the absolute basics of Docker and Rails containerization before moving on to writing configuration files, managing environment variables, and executing safe database commands. This course is designed for beginner web developers and Rails enthusiasts looking to modernize their development environment, with no prior Docker experience required.
