Ecosystem Configuration

While individual modules document their specific configuration properties, this page highlights shared ecosystem configurations that span multiple modules.

RabbitMQ Connection	AuditFlow, Checkout, Payment Gateway	Single broker, credentials injected via SPRING_RABBITMQ_USERNAME and SPRING_RABBITMQ_PASSWORD.
Auth Gateway JWKS URL	Auth Gateway, Checkout, Customer Portal	Standardized endpoint at /auth/jwks for token validation.
Observability (Tempo/Loki/Prometheus)	All modules	OTel endpoint injected globally via OTEL_EXPORTER_OTLP_ENDPOINT.
