Sample applications demonstrating use of Service Registry for Pivotal Cloud Foundry.

Service Registry sample

Expedition and Camelboy are example applications demonstrating the use of Service Registry for Pivotal Cloud Foundry. (For information on the Service Registry product, please see the documentation.)

Building and Deploying

1. Build the two projects from the root (greeting) directory. If using Maven, run:

   $ mvn package

   If using Gradle, run ./gradlew build (OS X, Linux) or gradlew.bat build (Windows).

   $ ./gradlew build

2. Run the deployment script (if you used Maven, scripts/deploy_mvn.sh or scripts/deploy_mvn.bat; if you used Gradle, scripts/deploy_gradle.sh or scripts/deploy_gradle.bat).

   $ ./scripts/deploy_gradle.sh

   The script will create a Service Registry service instance and then push the applications and bind them to the service.

Trying It Out

1. Visit [ROUTE]/hello, where [ROUTE] is the route bound to the Camelboy application. The Camelboy application will use the Service Registry to look up the Expedition app and get a greeting message, which (to begin with) should be “Hello, camel boy!”

   

2. You can see what the Expedition application is sending back by viewing its logs. Run cf logs expedition.

   $ cf logs expedition

3. To get a different greeting message, you can provide salutation and name parameters, as in [ROUTE]/hello?salutation=Come%20on&name=Jesse. The Camelboy application will send those parameters to the Expedition application and the resulting greeting will be customized to match.
