Build a 12-Factor Microservice with MicroProfile
summary
Shows how to implement the 12-factor rules with MicroProfile by building two microservices (A calls B) using MicroProfile Config, Fault Tolerance (retries, circuit-breaker, fallback), Health Check and REST Client on Open Liberty with Maven, Docker and Kubernetes/Helm. Demonstrates externalized config, injectable clients, health endpoints and scaling via replicas; live demo runs the services from GitHub, sometimes triggers failures to show recovery, and confirms the patterns work end-to-end.
