Bootiful kubernetes
summary
Creates a Spring Boot reactive service that writes sample customers to H2, exposes readiness and liveness probes via the Actuator, and records VCS metadata with the Git commit-id plugin. Demonstrates marking liveness down, a 15s slow endpoint, and configuring graceful shutdown 30s so in-flight requests finish before SIGTERM. Builds a container with paketo buildpacks via spring-boot:build-image, pushes to gcr.io/beautiful/bk, and shows an optional GraalVM native image that starts in ~0.15s and drops memory from hundreds of MB to tens of MB.
