Learn Docker in a Month of Lunches • Elton Stoneman & Bret Fisher • GOTO 2026
Elton Stoneman and Bret Fisher discuss the second edition of 'Learn Docker in a Month of Lunches', updated for 2025. They cover what's changed in the container ecosystem over the past five years, including multi-platform image support (Intel vs ARM), Docker Compose evolution from hyphenated to plugin form, BuildKit improvements, and image optimization and security scanning with tools like Trivy. They highlight a growing trend of developers jumping straight into Kubernetes without learning Docker fundamentals, and argue that understanding Docker internals—image layering, configuration injection, caching, and multi-arch builds—remains essential. The book is structured as practical, chapter-by-chapter exercises covering Dockerfiles, Compose, CI/CD with GitHub Actions, and cloud deployment options.
