Brilliant demo page not updated with env var DB_SERVICE_NAME

First thanks for a great demo page: https://developers.redhat.com/developer-sandbox/activities/learn-kubernetes-using-red-hat-developer-sandbox-openshift

However, master branch isn't updated with the necessary env. variable DB_SERVICE_NAME=mysql which is necessary after the version switch is made with the command kubectl set image deploy quotes quotes=quay.io/donschenck/quotes:v2 Without it you simply get nothing and error in the log.

It is available in the v2 branch but that is not used in the demo page either.

Thanks for finding this! I'll fix it and, if necessary, tweak the demo page.
