Building Reactive Microservices with Kotlin & running on Kubernetes
summary
Shows a concrete pipeline: use JHipster-Kotlin generator (npm generator-jhipster-kotlin) to scaffold a reactive Spring Boot/Project Reactor app in Kotlin, produce microservices (gateway, product, invoice, notification) with Postgres and MongoDB, generate Kubernetes YAML, build Docker images, push to Docker Hub and run with kubectl apply -f. Deploy succeeds: gateway exposes a LoadBalancer IP, readiness/liveness probes run, generated UI accepts login and CRUD on entities. Notes reactive tradeoff and suggests Reactive when throughput exceeds ~750 records/sec.
