Containerized a basic "Hello World" Vertx project with a unit test (https://github.com/bassdude5/Vertx_HelloWorld)

Steps for deploying to Openshift

1. Login to OpenShift:
   oc login
2. Login to Docker:
   docker login -u username -p $(oc whoami -t) docker.registry.url
3. Create a new OpenShift project:
   oc new-project vertx
4. Build the app to get the jar (note the jar name needs to be the same as the jar name specified in the Dockerfile):
   mvn clean install
5. Build the image (here we are specifying the openshift namespace so the image can be accessed across all namespaces):
   docker build -t openshift/java-fat-jar-example:latest .
6. View the image:
   docker images
7. Tag the image with docker.registry/image-name:version
   docker tag openshift/java-fat-jar-example docker.registry.url/openshift/java-fat-jar-example:latest
8. Push the image to the internal registry:
   docker push docker.registry.url/openshift/java-fat-jar-example:latest
9. Create the application (make sure you're in the correct namespace):
   oc new-app --docker-image=docker.registry.url/openshift/java-fat-jar-example:latest
10. Verify that your pods are up:
    oc get pods
11. Edit the service to route through port 8081 (as this app requires). Change the port, target port and the port name:
    oc edit svc servicename
12. Confirm that the service is correct:
    oc describe svc servicename
13. Expose the service:
    oc expose svc servicename
14. get the route:
    oc get route
15. Access the route via comand line or open in your browser:
    curl route
