Externalized Configuration - Eclipse Vert.x Booster

Important

While you can run and interact with this booster on localhost, you cannot take advantage of using externalized configuration with this booster without using OpenShift. For more details on using this booster with a single-node OpenShift cluster, CI/CD deployments, as well as the rest of the runtime, see the Eclipse Vert.x Runtime Guide.

Important

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

Important

As part of the process of creating this booster, developers.redhat.com/launch or the Fabric8 Launcher tool set 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 Locally

To run this booster on your local host:

$ git clone git@github.com:canyaman/appvx1

$ cd appvx1

$ mvn compile vertx:run

Interacting with the Booster Locally

To interact with your booster while its running, use the form at http://localhost:8080 or the curl command:

$ curl http://localhost:8080/api/greeting
{"content":"Hello, World!"}

$ curl http://localhost:8080/api/greeting?name=Sarah
{"content":"Hello, Sarah!"}

Running the Booster on a Single-node OpenShift Cluster

If you have a single-node OpenShift cluster, such as Minishift or Red Hat Container Development Kit, installed and running, you can also deploy your booster there. A single-node OpenShift cluster provides you with access to a cloud environment that is similar to a production environment.

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

$ oc login -u developer -p developer

$ oc new-project MY_PROJECT_NAME

Be sure that view access rights for the service account are added before deploying your booster using: oc policy add-role-to-user view -n $(oc project -q) -z default.
Navigate to the root directory of your booster.

Deploy your ConfigMap configuration using app-config.yml.

$ oc create configmap app-config --from-file=app-config.yml

Deploy your booster.
```
$ mvn clean fabric8:deploy -Popenshift
```

Interacting with the Booster on a Single-node OpenShift Cluster

To interact with your booster while it’s running on a Single-node OpenShift Cluster, you first need to obtain it’s URL:

$ oc get route booster-configmap-vertx -o jsonpath={$.spec.host}

booster-configmap-vertx-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME

You can use the form at your application’s url or you can use the curl command:

$ curl http://booster-configmap-vertx-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/greeting
{"content":"Hello World from a ConfigMap!"}

$ curl http://booster-configmap-vertx-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/greeting?name=Sarah
{"content":"Hello Sarah from a ConfigMap!"}

You can learn more about this booster and the Eclipse Vert.x runtime in the Eclipse Vert.x Runtime Guide.

Note	Run the set of integration tests included with this booster using `mvn clean verify -Popenshift,openshift-it`.
