This is an incredibly detailed and well-structured guide for Dockerizing a Next.js app! 🎉 The step-by-step instructions, clear directory organization, and smart use of Dockerfiles for both development and production make it super easy to follow. I especially appreciate the focus on optimizing the production image with multi-stage builds and leveraging docker-compose for seamless local development. Looking forward to the next part about setting up AWS EC2 and GitLab CI for deployment. Great work! 🚀👏
