Packaging --- mvn clean package

Start individual applications -

Starting the Eureka Server java -jar serviceRegistration/target/serviceRegistration-0.0.1-SNAPSHOT.war

Eureka Endpoint - http://localhost:1111/

Start the individual micro applications

java -jar challengesWeb/target/challengesWeb-0.0.1-SNAPSHOT.war

http://localhost:2222/

Start the same application in the same JVM different port Example - ava -jar target/app.jar --server.port=3331

Basically to override any spring boot properties use -- followed by Spring boot property name seprate with .

java -jar challengesWeb/target/challengesWeb-0.0.1-SNAPSHOT.war --server.port=3331

Your Microservice should be up at http://localhost:3331/api/challenges

Starting the Heroes Application

java -jar heroWeb/target/heroesWeb-0.0.1-SNAPSHOT.war

Your other microservice should be up at http://localhost:2222/heroes

Replicated Heroes Micro Application

java -jar heroWeb/target/heroesWeb-0.0.1-SNAPSHOT.war --server.port=2223

Replicate Microservice should be up at http://localhost:2223/heroes

Starting the zuul Proxy

java -jar zuulGateway/target/zuulGateway-0.0.1-SNAPSHOT.jar

Deployed at port 5555

You should be able to access your API using the Zuul gateway

Heroes API via proxy - [Secure end point- basic security , User Name - user. Password - password ] http://localhost:5555/heroes-service/heroes

Challenges API via proxy - http://localhost:5555/challenges-service/api/challenges
