ListenerSet

ListenerSet defines a set of additional listeners to attach to an existing Gateway. This resource provides a mechanism to merge multiple listeners into a single Gateway. The parent Gateway must explicitly allow ListenerSet attachment through its AllowedListeners configuration. By default, Gateways do not allow ListenerSet attachment. Routes can attach to a ListenerSet by specifying it as a parentRef, and can optionally target specific listeners using the sectionName field. Policy Attachment: - Policies that attach to a ListenerSet apply to all listeners defined in that resource - Policies do not impact listeners in the parent Gateway - Different ListenerSets attached to the same Gateway can have different policies - If an implementation cannot apply a policy to specific listeners, it should reject the policy ReferenceGrant Semantics: - ReferenceGrants applied to a Gateway are not inherited by child ListenerSets - ReferenceGrants applied to a ListenerSet do not grant permission to the parent Gateway's listeners - A ListenerSet can reference secrets/backends in its own namespace without a ReferenceGrant Gateway Integration: - The parent Gateway's status will include "AttachedListenerSets" which is the count of ListenerSets that have successfully attached to a Gateway A ListenerSet is successfully attached to a Gateway when all the following conditions are met: - The ListenerSet is selected by the Gateway's AllowedListeners field - The ListenerSet has a valid ParentRef selecting the Gateway - The ListenerSet's status has the condition "Accepted: true"
