• Java 8

Build Images and Start Docker

./gradlew dockerCompose

This task will build the images and start the container

Application Dependencies

There are two applications App1 and App2. App1 depends on App2

Testing

Run the command docker ps to determine the container id. Using that do docker inspect <container-id> Extract the Ip Address from the value provided. A sample output is shown below

The port exposed for App1 is 8080 and 8090 for App2 Once you have the IP address for App1 do the below in your favourite browser

• type http://<IP Address>:8080/hello?name=<your name>. You should see Hello from app1.
• type http://<IP Address>:8080/helloApp2?name=<your name>. You should see Hello from app1 (here App1 is sending the request to App2 and this is the response of App2)
