Containerization with Docker

Docker containers have fundamentally changed how applications are packaged, shipped, and deployed. Building efficient images requires understanding multi-stage builds, layer caching, security scanning, and the difference between development and production image configurations.

The resources below demonstrate practical patterns for writing optimized Dockerfiles, orchestrating multi-container applications with Docker Compose, debugging running containers, and integrating container builds into CI/CD workflows.
