  === Image Change Trigger
  
  The ImageChange trigger results in a new deployment whenever the value of an
  image stream tag changes either by a build or because it was imported.
  
  The following is an example of an ImageChange trigger:
  
  ====
  
  [source,json]
  ----
  triggers: 
    - type: "ImageChange"
      imageChangeParams: 
        automatic: true <1>
        from: 
          kind: "ImageStreamTag"
          name: "origin-ruby-sample:latest"
        containerNames: 
          - "helloworld"
  ----
  <1> If the `*automatic*` option is set to `false`, the trigger is disabled.

  With the above example, when the `latest` tag value of the `origin-ruby-sample`
