Howto: Options Galore to Get from Source Code to Container
summary
Compares multi‑stage Dockerfiles (with BuildKit) against Cloud‑Native Buildpacks (pack/Paketo) and jib/chip, showing concrete tradeoffs: mounting a local Maven cache via BuildKit cache mount cuts repeated dependency downloads so rebuilds finish in seconds versus minutes; pack / Paketo produces layered images with a rebase path to swap OS layers without rebuilding app layers; extracting layered JARs puts dependencies in a mostly stable layer so only classes change. Demos produce reproducible timestamps and very fast container builds (single‑digit seconds) and warn when Docker image IDs still vary by build time.
