From Zero to Hero in Kubernetes Native Java
summary
Step-by-step demo of scaffolding a Java service with Quarkus (Maven), generating Dockerfiles and Kubernetes YAML automatically, and using continuous testing and Dev Services to spin up a Postgres test container. Shows building a native executable 41 MB with GraalVM-like native-image, measured startup ~21 ms and resident ~13 MB versus ~1.2 s and ~88 MB on the JVM. Demonstrates pushing images, auto-generated manifests, remote live-reload into a Kubernetes cluster, and reading ConfigMap/Secret-based config.
