Cloud Native with Java, Spring Boot and Kubernetes
summary
Shows how to build a small Java Spring Boot HTTP service with Gradle, package it as a container image using Cloud Native Buildpacks, push the image via a GitHub Actions pipeline to a registry, and deploy it to Kubernetes using Deployment, Service and Ingress. Demonstrates overriding config with ConfigMaps and Secrets, enabling graceful shutdown plus liveness/readiness probes via Spring Boot Actuator, and exposing Prometheus metrics and tracing; the demo includes a zero-downtime rollout.
