For the reviewers, going though the code I'd add definitely add some test cases with such annotations, unit and e2e.

PTAL comment about checking the annotations type at the caller level and the utils just doing the update task.

pkg/kn/commands/service/configuration_edit_flags.go

err = servinglib.UpdateAnnotations(service, template, annotationsMap, []string{})
err = servinglib.UpdateRevisionTemplateAnnotation(template, autoscaling.InitialScaleAnnotationKey, strconv.Itoa(p.ScaleInit))

IMO, we should have two utils

  • UpdateRevisionAnnotations
  • UpdateServiceAnnotations
    Each taking respective object, toUpdate and toRemove map.
    The callers of these utils can then decide if the given annotations should be set on either or both (explaining why in comments).

In the current codebase there's only one place that UpdateAnnotations is used and needs to be changed to filter autoscaling annotations. I tried to aim for quick win to unblock CI etc. However, I do agree that separate Update* util methods are likely better solution to expose filtering logic at caller level. I'll update the PR shortly. 😉
