Docker Containerization

This one walks you through building production-ready Docker containers with multi-stage builds, security hardening, and image optimization. You'll get concrete examples for Node.js, Python, Java, and Go apps, plus reference guides on dockerignore patterns, compose setups, and running as non-root users. The quick start shows a solid multi-stage Node build that actually demonstrates the patterns instead of just talking about them. Most useful when you're past basic containerization and need to ship something secure and lean, or when you're tired of bloated images with root access everywhere. The security and optimization sections cover the stuff that's easy to skip but painful to fix later.
