Docker for Node.js: Development to Production

Containerizing Node.js applications is essential for modern software delivery, yet configuring them for optimal speed, security, and size can be challenging. Transitioning your local Node.js projects into production-ready Docker containers requires a clear understanding of how the runtime and container layers interact. This text-based course guides you through the foundational concepts of containerization specifically tailored for Node.js developers. You will learn how to structure Dockerfiles, optimize build times, manage dependencies efficiently, and secure your applications for real-world deployments. What you'll learn: - Understand foundational container concepts and how Docker interacts with the Node.js runtime - Build optimized Docker images using multi-stage builds and efficient layer caching strategies - Manage node_modules and modern package managers within containerized environments - Configure local development workflows with container-based live-reloading - Implement container security best practices, including non-root users and minimal base images - Connect Node.js applications to databases like MongoDB using Docker Compose networks The course starts with essential terminology and basic container concepts before moving step-by-step through local development configurations, dependency management, and production-grade optimization techniques. You will learn through clear explanations and structured written exercises designed to reinforce practical implementation. This course is designed for web developers and software engineers who want to learn how to containerize their Node.js applications effectively. A basic familiarity with Node.js is helpful, but no prior Docker experience is required as we cover the fundamentals from the ground up.
