xlistenerset

XListenerSet 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 an "AttachedListenerSets" condition - This condition will be: - True: when AllowedListeners is set and at least one child ListenerSet is attached - False: when AllowedListeners is set but no valid listeners are attached, or when AllowedListeners is not set or false - Unknown: when no AllowedListeners config is present
