exercising Service Catalog within OpenShift

a.1 Overview

You can validate Service Catalog using a couple of different approaches.  The Service Catalog E2E is one (see the instructions 
for syncing Service Catalog to OpenShift).  Additionally, you can utilize the OpenShift web console or the CLI and add 
applications exposed by the Template Service Broker or Ansible Service Broker.  Note that some Templates create applications 
directly and some use the Service Catalog.  Python & HTTPD don't use Service Catalog, most templates with "persistent" in the 
name do.  For those that don't, there is no ServiceInstance, Class or binding created.  Once you add applications to your 
project, you should be able to see them via the CLI (oc get serviceinstances --all-namespaces)

In the OpenShift web console (https://127.0.0.1:8443) login as Developer (any password works) and select MyProject (or any 
other project and then "Add to Project", "Browse Catalog".  I believe the Ansible Service Broker offerings have (APB) in the 
name. 

You can also create a Service Instance & Binding via the cli (oc) using the attached JSON files.  First create the secret 
which has the required parameters for the service (I got this from Sam Padgett), then create the instance and then the binding.
I.E.,

oc create -f secret.json
oc create -f instance.json
oc create -f binding.json

a.2 Adding Ansible Service Broker

Start OpenShift:
$ oc cluster up --version=latest --service-catalog

Login:
$ oc login -u system:admin

Start ASB:
wget https://raw.githubusercontent.com/openshift/ansible-service-broker/master/scripts/run_latest_build.sh

I edited run_latest_build.sh and commented out the start of oc (oc cluster up...) and set DOCKERHUB_USER anDOCKERHUB_PASSWORD.
