Epic Goal

• We want to set up a flow:
  • to allow the Hypershift team to provide the Git sources of all 8 container images that make up the hypershift operator to ACM CICD
  • for ACM CICD build downstream images based on the input Git sources and extract image manifests of those 8 hypershift container images
  • push the image stream configmap to some Gitlab repo for SD fleet manager to take and apply it to a service cluster

Why is this important?

• This allows the hypershift operator delivery schedule to be independent of ACM 
• This allows to upgrade only the hypershift operator without having to re-install or upgrade ACM when no fix is required for ACM

Scenarios

1. The hypershift Dev team wants to roll out a new version of hypershift operator to SD
2. The hypershift Dev team commits a set of Git sources that make up the new version of hypershift to ACM CICD pipeline  (https://issues.redhat.com/browse/HOSTEDCP-665)
3. ACM CICD pipeline builds new set of hypershift container images
4. ACM CICD extracts the hypershift images manifests and build a image override configmap (example documented here https://github.com/rokej/hypershift-addon-operator/blob/placement_score/docs/upgrading_hypershift_operator.md#overriding-the-hypershift-operator-image-references-1) and commits it to Gitlab for SD fleet-manager to consume
