Dockerfile vs Jib vs Pack vs Native Image: Which Is the Best Image Build Method?
summary
Compares four ways to build container images for a Spring Boot Java 17 app: Dockerfile (standard JDK image ~380 MB), Jib (produces a distroless ~288 MB image without Docker), buildpacks/pack (CNB) (~278 MB), and GraalVM native AOT. Measures image size, startup latency and throughput: native AOT gives the smallest binary (~98 MB, compressible to ~40 MB) but needs ~8 GB RAM and minutes to build; native starts ~100× faster (cold latency ~3.3 ms vs ~300 ms) and delivers about 10× throughput improvements.
