A live stream discussion comparing Cloud Native Buildpacks (CNB) to Dockerfiles, featuring Terrence Lee from Heroku. The conversation covers the history of buildpacks from Heroku's classic slugs to the modern OCI-compatible CNB spec, key advantages of buildpacks including standardization, composability, centralized policy enforcement, and OS-level rebasing for CVE patching without full rebuilds. A live demo walks through the pack CLI, builder images, the detect/build lifecycle, layer caching mechanics, and how to create custom buildpacks. Topics also include the 127-layer limit, deterministic builds via epoch timestamps, and how platform teams can use buildpacks to enforce guardrails across development teams without requiring Dockerfile expertise.
