Kubernetes Native Java.

on YouTube ↗59m

" summary

Shows how to build a Kubernetes-ready Spring Boot app on Java 17 using reactive web/R2DBC and H2, expose actuator health, readiness and liveness probes, and enable graceful shutdown with a 30s SIGTERM window. Demonstrates Spring Cloud Gateway filters, GraphQL with batch mapping to avoid N+1, Micrometer → Prometheus metrics, and a declarative HTTP client via HTTP service proxy factory. Builds a Spring Native / GraalVM native image (~78 MB) that boots in ~57 ms on macOS; production caveats about reflection hints and Jakarta EE package migration are noted.
