RFE: Watch labels #1808
Description
Feature Request
In #314 / #428, the ability was added to watch by label selector. This is useful if the watch would otherwise cause a lot of unnecessary objects to be kept in cache / sent over the wire. However, with the move to the controller-runtime, it seems that feature was lost.
What I really need for my particular use case is the ability to watch for all configmaps with a specific label, in all namespaces. I'd like to avoid keeping all configmaps in memory.
It may be that this particular use-case is too far outside the scope of a normal operator, in which case that's fine. I still think that label-based watches would be useful :-)
