Spring On Kubernetes
summary
Shows a tiny Spring Boot app built from the GitHub repo then containerized and deployed to Kubernetes using a local registry; kustomize layers reduce ~500 lines of YAML to kustomize transforms and a 9-line customization, adding actuator liveness/readiness probes as a one-line transformer. Uses skaffold dev with port-forward to auto-build (jar → image), push and hot-redeploy, and to clean up the cluster afterwards. Demonstrates Spring Boot 2.3’s build-image buildpacks (150 MB JDK download, cached), metadata and memory-calculator, and tradeoffs vs Jib.
