Java applications containerized and deployed, make your buildpack edition
summary
Compares Dockerfile multi-stage builds, Google Jib and CNFC buildpacks with concrete tradeoffs: Docker is generic but needs a daemon, Jib produces reproducible images and uses Jib layering to avoid rebuilding unchanged classes, buildpacks use a pack CLI and compose many tiny packs (demo shows 7 of 16 buildpacks participating). Shows how to author a stack, buildpack detect/build scripts, create a custom builder, use rebase to swap base images, build Java 17 images and deploy via GitHub Actions to fly.io — demos succeed end-to-end.
