Overview

An image stream can be referred from other OpenShift objects, such as a deployment configuration. An image stream tag is referred by name, which is <image-stream-name>:<tag-name>.

- type: ImageChange
   imageChangeParams:
     ...
     from:
       kind: ImageStreamTag
       name: gogs:0.11.29
