" summary

Claim: deliver 15-factor cloud‑native apps using Spring Boot and Kubernetes by building a small API‑first service, packaging it with buildpacks over Dockerfiles, and running it on a local k8s cluster (Docker Desktop / kind) with Flux CD and Knative. Uses Spring Boot actuator + Micrometer for metrics, Prometheus RSocket proxy for remote scraping, spring‑cloud‑kubernetes for configMaps and service discovery, and Spring Cloud Contract / Spring REST Docs for API contracts. Demo shows mvn spring‑boot:build-image and horizontal, disposable scaling.
