Kubernetes. From 0 to Production-Grade with Java.
summary
Builds a Quarkus app, packages it with Docker/Podman, and pushes an image for Kubernetes; uses Kafka and ephemeral PostgreSQL for the demo, and shows the repo quarkus-kubernetes-kafka-db. Adds Quarkus + Kafka + PostgreSQL integrations, health + readiness + startup probes so pods only receive traffic when ready, and configures resource requests/limits (example: 300MB request, 400MB limit, 1 CPU) plus JVM options (MaxRAMPercent 75, parallel GC). Adds OpenTelemetry/Micrometer tracing and a working phone-accelerometer car-race demo (teams 35 vs 19).
