Cloud Native with Spring Boot & Kubernetes
summary
Builds a Reactive Spring Boot 2.6 app on Java 17, packages it with Cloud Native Buildpacks (Paketo) via boot build-image and GitHub Actions to publish to Docker Hub, deploys to Kubernetes with Knative for scale-to-zero, and wires ConfigMaps/Secrets plus actuator/health readiness liveness probes. Shows Prometheus metrics, resource requests/limits guidance, and adds Spring Native (GraalVM) to produce native images with ~0.1s startup, trading slower CI builds for much lower runtime memory and instant cold-starts.
