Epic Goal

The goal of this Epic is to do GA release for the right-sizing recommendation for both namespace as well as virtualization solution as part of the ACM (MCO) deployment based on a configuration/feature flag for OBSDA-1094 feature request.

Why is this important?

Currently we have namespace as well as virtualization right-sizing recommendation available as Tech preview solution along with MCO. Several customers are waiting for the GA release of this feature. To onboard more customers, we working towards GA release of the right-sizing recommendation feature.

Scenarios

...

Acceptance Criteria

• Right-sizing recommendation must enable automatically when multicluster observability is enabled on the hub.
• Right-sizing feature must be enabled by default for GA (unlike Tech Preview where it was disabled).
• Users must be able to configure:
  • include/exclude namespaces
  • label criteria
  • recommendation percentage
  • placement options
• System must reconcile and recreate required components if deleted or if configuration changes.
• All necessary GA code changes must be implemented along with updated/added unit tests.
• All CI test cases must pass.
• Changes must be validated by deploying a custom image in an ACM cluster before raising a PR.
• PR must obtain required approval from the MCO team before merge.
• After merge and ACM build availability, validate that the feature works as expected.
• Feature must be compatible with supported OpenShift versions (4.19, 4.20, 4.21).
