Spring to Image
summary
Docker images become the immutable artifact for Spring apps and buildpacks replace brittle Dockerfiles by producing images directly; the demo builds an image that runs, using Cloud Native Buildpacks and the Paketo implementations (about 17 buildpacks pulled), with Spring Boot Maven/Gradle plugins or the pack CLI to assemble layered images for aggressive caching and fast rebuilds. Buildpacks contribute a JRE, JVM tuning (memory calculator, CPU/dns helpers), spring-aware slicing of layers, image labels and BOM metadata, and a Kubernetes-native kpack watches source and produces new tagged images automatically.
