An example app using spring cloud and mongo-db to show how one could start to build an online flight booking API.

Testing the app

Dependencies

The following required services need to be started up

1. Zipkin:
   • Using Docker: docker run -p 9411:9411 openzipkin/zipkin
   • Directly: curl -sSL https://zipkin.io/quickstart.sh | bash -s java -jar zipkin.jar
2. RabbitMQ
   • docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3.10-management
   • Download and install from https://www.rabbitmq.com/download.html
3. Prometheus
   • In the prometheus directory: docker run -p 9090:9090 -v <full-path>\cloud-flights\prometheus\prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus

Microservices

To get the solution running, the different microservices need to be fired up in this order:

1. Eureka Server
2. Config Server
3. Cost service
4. Flight service
5. Booking service
6. Cloud Gateway

Each of these can be started up by running mvn spring-boot:run in the appropriate directory
