Live coding: Configuring your cloud-native applications with MicroProfile Config

on YouTube ↗44m

" summary

Live coding shows MicroProfile Config 2.0 wired into an Open Liberty Java app (VS Code, Maven), building a Docker image and deploying to Kubernetes with deployment.yaml and environment-backed ConfigMaps so configuration changes apply without repackaging. Demonstrates config profiles (dev/test/prod picking different discounts like 10/50/70), aggregating properties into @ConfigProperties beans, creating a custom ConfigSource ordinal 700 that overrides defaults, and reading live-updated values via Config/Provider; service listens on NodePort 381.
