User Story

As a cluster admin, I want to be told that my authoritative API change may not be effected immediately so that I understand that I may need to check back later.

Background

Since we know that authoritative API changes may not always be effected immediately (synchronization errors), we must warn admins that their actions may not take effect.

This could be implemented using ValidatingAdmissionPolicy.

Behaviours

• Warn users when they try to change spec.authoritativeAPI but condition Synchronized is False

Steps

• Implement a ValidatingAdmissionPolicy and the appropriate bindings that would emit a warning when the user attempts to change the authoritative API but it is not synchronized

Stakeholders

• Cluster infra

Definition of Done

• When changing the authoritative API on a non-synchronized resource, a warning is emitted that tells the user that the resource is not synchronized and that the authority change may not be effected immediately.
