API Gateway Example

This module illustrates the construction of API gateway using Quarkus, RESTEasy Reactive, the Reactive REST Client and Fault Tolerance. The system is composed by:

• a quote service
• a greeting service
• the api gateway

Running the Quote Service

In a terminal, navigate to the chapter-12/api-gateway-example/quote-service directory and run:

> mvn package
> java -jar target/quarkus-app/quarkus-run.jar

The application is listening on the port 9020.

Running the Greeting Service

In another terminal, navigate to the chapter-12/api-gateway-example/greeting-service directory and run:

> mvn package
> java -jar target/quarkus-app/quarkus-run.jar

The application is listening on the port 9010.

Running the API Gateway

In a third terminal, navigate to the chapter-12/api-gateway-example/api-gateway directory and run:

> mvn quarkus:dev # Or package and run it.

Invoke the application as follows:

> curl http://localhost:8080 # Call both services 
> curl http://localhost:8080/quote # Just call the quote service
