Live Coding 12-Factor App with MicroProfile and Kubernetes
summary
Live-coded a two-service 12‑Factor example: Service A on Open Liberty calls Service B on Quarkus, both built with Maven, containerized (Docker) and deployed to Kubernetes with deployment YAML and replica=2. Configuration uses MicroProfile Config and Kubernetes env/ConfigMap override; service-to-service calls use MicroProfile Rest Client and fault tolerance (retry timeout fallback) so slow/errant backend produces successful responses via timeout+retry. Health liveness/readiness probes, port binding and CI-friendly build→release→run steps are shown and the deployment works as demoed.
