Prometheus with Spring Boot using service discovery via Eureka
Prometheus doesn't natively support Eureka as a service discovery mechanism.
This is a demo of adapting Eureka to support Prometheus, and example of scraping a relabelling configuration.
Uses Eureka Consul Exporter to expose Eureka metadata via Consul apis and using Consul metadata.
Prometheus can then use the native Consul support to discovery targets.
To build use: mvn clean install
Then docker-compose up to bring up
- Prometheus (port 9090)
- Grafana (port 3000)
- Blackbox Exporter (port 9115)
- Eureka (port 8761)
- Spring Boot Demo app registered with Eureka (port 8080)
