Fuse Aggregation

The booster demonstrates how to aggregate JSON data from 2 services using Camel.

Use this booster to:

• Execute an HTTP GET request on the camel/flights endpoint to retrieve a list of flights (arrivals and departures). Arrivals and Departures are aggregated from 2 separate services. See CamelRouter.java for how these 2 services are aggregated. These services are configured to be local service beans by default. However, you can change the camel routing to fetch data from 2 mock servers (included in this booster).

• Browse the API’s Swagger page.

Deployment options

You can run this booster in the following modes:

• Single-node OpenShift cluster

• OpenShift Online at https://developers.redhat.com/launch

• Standalone on your machine

The most effective way to use this booster is to deploy and run the project on OpenShift.

For more details about running this booster on a single-node OpenShift cluster, CI/CD deployments, as well as the rest of the runtime, see the Spring Boot Runtime Guide.

Important

This booster requires Java 8 JDK or later and Maven 3.3.x or later.

Running the booster on a single-node OpenShift cluster

A single-node OpenShift cluster provides you with access to a cloud environment that is similar to a production environment.

If you have a single-node OpenShift cluster, such as Minishift or the Red Hat Container Development Kit, installed and running, you can deploy your booster there.

To deploy this booster to a running single-node OpenShift cluster:

1. Download the project and extract the archive on your local filesystem.

2. Log in to your OpenShift cluster:

   $ oc login -u developer -p developer

3. Create a new OpenShift project for the booster:

   $ oc new-project MY_PROJECT_NAME

4. Change the directory to the folder that contains the extracted booster application (for example, my_openshift/fuse-rest-http-booster) :

   $ cd my_openshift/fuse-rest-http-booster

5. Build and deploy the project to the OpenShift cluster:

   $ mvn clean -DskipTests fabric8:deploy -Popenshift

6. In your browser, navigate to the MY_PROJECT_NAME project in the OpenShift console. Wait until you can see that the pod for the fuse-rest-http-booster application has started up.

7. On the project’s Overview page, locate the URL for the fuse-flights-aggregator application. The URL uses this form: http://fuse-flights-aggregator-MY_PROJECT_NAME.OPENSHIFT_IP_ADDR.nip.io.

8. Click the URL to access the Flights Service and then follow the instructions on that page.

Running the booster on OpenShift Online

To deploy this booster directly to OpenShift Online when you create the project at https://developers.redhat.com/launch.

1. Go to https://developers.redhat.com/launch.

2. At the Deployment step, select Use OpenShift Online.

3. Follow the on-screen instructions to create a new REST API Level 0 project by using the Fuse runtime.

Note	As part of the process of creating this booster, https://developers.redhat.com/launch sets up a project with a CI/CD deployment of this booster. You can see the status of this deployment in your single-node OpenShift cluster or OpenShift Online web console.

Running the booster standalone on your machine

To run this booster as a standalone project on your local machine:

1. Download the project and extract the archive on your local filesystem.

2. Build the project:

   $ cd PROJECT_DIR
   $ mvn clean package

3. Run the services:

   $ mvn spring-boot:run

4. Go to http://localhost:8080 and then follow the instructions on that page.
