Reactive Systems with Eclipse Vert.x and Kubernetes
summary
Live-coding builds four reactive microservices with Eclipse Vert.x, packages them as fat JARs and containers, and deploys to OpenShift/Kubernetes; an in-memory shopping list is replaced with Redis for shared state, service discovery wires services together, and rolling updates reveal stale-in-memory issues fixed with readiness/liveness probes. Code uses Vert.x Web, reactive streams with backpressure, HTTP chunked responses, and a circuit breaker for timeouts; runtime claims include a single-threaded event loop model and a produced 7.8 MB fat jar that runs and scales successfully.
