prow-controller-manager manages the job execution and lifecycle for jobs running in k8s.
It currently acts as a replacement for Plank.
- Eventbased rather than cronbased, hence reacting much faster to changes in prowjobs or pods
- Per-Prowjob retrying, meaning genuinely broken prowjobs will not be retried forever and transient errors will be retried much quicker
- Uses a cache for the build cluster rather than doing a LIST every 30 seconds, reducing the load on the build clusters api server
Exclusion with other components
This is mutually exclusive with only Plank. Only one of them may have more than zero replicas at the same time.
