Deploying Node.js Apps with Nginx and Docker

Modern web deployment requires robust security, efficient traffic routing, and reliable containerization. If you want to transition your local Node.js application to a production-ready environment, understanding how to layer Nginx and Docker is an essential skill. This text-based course guides you through the process of containerizing a Node.js application and placing an Nginx reverse proxy in front of it to handle incoming requests. You will learn to build clean, maintainable deployment environments using industry-standard configurations. What you'll learn: Understand the fundamental concepts of reverse proxies, containerization, and modern web architecture; Configure Dockerfiles and Docker Compose to containerize Node.js applications and Nginx services; Set up Nginx as a reverse proxy to route client requests to your backend; Implement security best practices, including custom headers and basic access controls in Nginx; Manage environment variables and network communication between isolated Docker containers; Practice troubleshooting common connection and configuration errors through detailed written guides. You will start by learning core concepts of networking and containerization before moving step-by-step through configuration files, environment setups, and multi-container orchestration. By reading through practical examples and analyzing configuration scripts, you will gain a clear mental model of modern deployment workflows. This course is designed for beginner backend developers, systems administrators, and aspiring DevOps engineers who have a basic familiarity with Node.js but are new to Nginx and Docker. No prior containerization experience is required. Start reading today to master the foundations of secure and scalable application deployment.
