Removing labels/annotations

[mgoodness]

My DecoratorController is able to apply labels & annotations to resources (in my case, Namespaces) by returning corresponding maps. Is there a mechanism for removing them? Returning empty maps doesn't seem to do the job.

The returned map is merged into existing values, so an empty map is interpreted as, "don't change anything." You can remove existing keys by explicitly setting each one to null.
