Epic Goal

The goal of this Epic is to automatically deploy the virtualization right-sizing solution as part of the ACM (MCO) deployment based on a configuration/feature flag for OBSDA-1045 feature request.

Why is this important?

Currently, we have developed the Virtualization right-sizing dev preview solution, and users can deploy it manually by following the guidelines. We’ve received positive customer feedback so far, and several customers are waiting for the tech preview release of this feature. To onboard more customers, we plan to release the Tech Preview alongside the MCO/ACM release similar to namespace right-sizing recommendation(ACM-17966).

Acceptance Criteria

• The ACM Virtualization right-sizing Namespace solution should be enabled automatically based on the feature flag in MCO CRD. Users should not need to manually apply any YAML files to enable the Virtualization right-sizing solution.
• Extend MCO codebase to add Virtualization right-sizing recommendation feature
• Write unit test cases for the added code, all CI test cases should be passed.
• User should be able to configure include/exclude namespace, label criteria, recommendation percentage, placement via config.
• Required component should be reconciled if deleted or based on updated any configuration.
• Test changes by deploying custom image in ACM cluster setup before raising PR
• Get required approval from MCO team on PR and merge the changes.
• After code merge once we have ACM build, test it out required feature working expected or not.
