Promotion reconciler
This controller is responsible for making sure that promotions happen, even if the promotion job fails for whatever reason.
To do so it:
- Watches Images (As ImageStreamTags do not support watching)
- Finds the corresponding promotion job or returns
- Checks if the ImageStreamTag was build from the latest revision in the given repo+branch
- If not: Enqueues a request onto the
prowjobreconciler - The
prowjobreconcilerthen checks if there is currently an active prowjob for this revision and if not, creates one.
The two reconciler approach was chosen because in most cases, we build many ImageStreamTags from one ProwJob but we need to react to ImageStreamTags. Using this approach allows us to de-duplicate requests for the same ProwJob and hence to avoid creating one per ImageStreamTag it promotes to.
