Spring Boot Loves K8s
summary
Spring Boot 2.3 adds concrete Kubernetes support: layered jars (opt‑in) and a build-image goal that uses Cloud Native buildpacks to produce multi-layer images so rebuilds touch only changed layers. Demo switches from Java 8 to 11 and only the JDK layer changes. The app (markdown UI + renderer behind a circuit breaker with degraded fallback) uses new liveness and readiness actuator groups and a 30s graceful shutdown so in-flight requests complete instead of failing.
