Configuration Management with Kubernetes, a Spring Boot use case
summary
Demo Spring Boot app shows environment banners and uses @ConfigurationProperties and @Value for wiring, with images built by the Jib plugin and deployed to Minikube via Kubernetes Deployment Service and Namespace. Configuration methods demonstrated are profiles, JVM system properties, environment variables, ConfigMap key value pairs, and a Git-backed initContainer git clone that populates /config for Spring to read. Secrets handle passwords, runtime changes require pod restarts, and the demos run successfully.
