Docker for Production: Deploying and Scaling Rails and Web Apps

Moving applications from a local development environment to a reliable production setup can be a challenging transition. Containerizing with Docker simplifies this process, but real-world production deployments require addressing security, scaling, and architectural limitations. This text-based course guides you through the foundational concepts of Docker, transitioning your mindset from local development to production-ready container orchestration. You will learn to containerize web applications, optimize images, and manage deployments with confidence. What you'll learn: - Understand core Docker terminology, container lifecycles, and image architecture. - Build optimized, multi-stage Dockerfiles to minimize production image sizes. - Configure environment variables and manage persistent data securely. - Deploy and scale Rails and modern web applications in production environments. - Navigate common Docker limitations, resource constraints, and security best practices. - Implement basic CI/CD container workflows and observability strategies. Starting with foundational container concepts, the course moves systematically into production architecture, multi-stage builds, and deployment strategies for web applications. You will read clear explanations, analyze clean configuration patterns, and work through practical deployment scenarios at your own pace. This course is designed for web developers and system administrators who want to transition their applications to production containers. No prior DevOps or Docker experience is required, as we start with the absolute basics. Start reading today to build a robust, containerized production environment for your applications.
