summary
Compares concrete OSS image builders for JVM apps: multi-stage Dockerfile with BuildKit caching, Google JIB (builds without a container daemon), Paketo Cloud Native Buildpacks and Source2Image. Measures are build time, resulting image size and layer breakdown (example: app layer ~19.6 MB vs larger dependency layer), reproducibility, and security. Demonstrates splitting classes/resources to avoid full rebuilds, shows JIB/pack workflows producing pushable images and Paketo’s rebase capability to swap base layers for vulnerability fixes; demos run successfully end to end.
