title: How to change a buildConfig in OpenShift 3
body: <p>I'm working through the sample tutorial on OpenShift 3. I created the example application nodejs-mongodb-example. But in the "edit parameters" step, I put the wrong URL to my forked repository, and I get a failed build.</p>
  
  <p>I thought maybe I'd be able to extract the buildConfig file (is that a template?) on the command line, but I haven't found a way to do that.</p>
  
  <p>Is there a way to edit and replace this bad buildConfig without deleting all of the application objects and starting over?</p>
