Practice and testing with Java 11, Prometheus, and Spring-boot with MicroService Architecture. Designed to run on Kubernetes in minikube.

This application was written by Andrew Aslakson

• Built to run on minikube using kubernetes

• General race tracking system?

• Secure with Firebase Authentication?

• Build React app too? - realistically probably just postman.

Tech Stack

• Java 11
• Maven
• Spring-Boot
• Prometheus
• Jacoco
• Lombok

Running Instructions

• tests "mvn clean test -Dspring.profiles.active=test"
  • this generates jacoco reports and runs all Unit and Integration tests
  • test profile uses H2 database, and populates it with 5 test users
• Running: because tests have special configuration
  • package with "mvn clean package -Dmaven.test.skip"
    • default package is set to "local"
  • package with: "mvn clean package -Dmaven.test.skip"
    • !Not implemented!
  • run with "mvn spring-boot:run -Dspring.profile.active=dev"
• local Environment: Uses h2 database, used while developing
• Dev Environment: meant to be for kubernetes, most likely connects to DB hosted on kubernetes
  • Not yet actually configured
• h2-console: configured to be at: "localhost:5000/h2-console", URL: "jdbc:h2:mem:local"
  • Username: admin
  • password: password
• Prometheus Statistics: reached at: "localhost:5000/actuator/prometheus"
