Setup
- Run all services
- Create at least 1 department via API
- Create at least 1 user via API
- Use APIs to manage departments/users
Test Circuitbreaker
Same as Setup but stop department-service), use the API to fetch departments whilst monitoring the hystrix-dashboard - the service should still respond but using a cloud-gateway circuitbreaker fallback controller.
Todo
- Dockerize
- Replace hystrix with resilience4j & find replacement dashboard
