Multi-Container Applications with Docker Compose and MySQL

Modern software development relies heavily on containerization to ensure applications run consistently across different environments. If you want to move beyond single-container setups and start building resilient, multi-tier architectures, understanding how to orchestrate your database and application layers is essential. This text-based course guides you through the foundational concepts of container communication, data persistence, and multi-service management. You will start with the core definitions of containerization, learn how to configure network bridges, and progress to writing clean configuration files. What you will learn: Understand the core principles of containerization and multi-service architecture; Configure Docker Compose files to orchestrate applications and MySQL databases; Establish secure and persistent data volumes for database storage; Manage container networks to allow seamless communication between services; Apply modern environment variable patterns to secure sensitive database credentials; Troubleshoot common container startup and dependency issues. The course begins with essential terminology and setup concepts before walking you through the structure of compose files, database initialization, and service integration. This course is designed for beginner developers, system administrators, and DevOps enthusiasts who have a basic understanding of command-line interfaces but are new to multi-container workflows.
