feat: add --watch-namespaces to scope the informer cache - #130
Merged
Conversation
The manager was created with no cache configuration, so the informer set was whatever the controllers happened to touch, cluster-wide and unfiltered. --watch-namespaces (Helm: watchNamespaces) sets Cache.DefaultNamespaces. Empty, the default, keeps the current cluster-wide behaviour, so this is not a behavioural change on upgrade.
