This is a clone of issue OCPBUGS-5943. The following is the description of the original issue:
Kube 1.26 introduced the warning level TopologyAwareHintsDisabled event. TopologyAwareHintsDisabled is fired by the EndpointSliceController whenever reconciling a service that has activated topology aware hints via the service.kubernetes.io/topology-aware-hints annotation, but there is not enough information in the existing cluster resources (typically nodes) to apply the topology aware hints.
When re-basing OpnShift onto Kube 1.26, are CI builds are failing (except on AWS), because these events are firing "pathologically", for example:
: [sig-arch] events should not repeat pathologically
events happened too frequently event happened 83 times, something is wrong: ns/openshift-dns service/dns-default - reason/TopologyAwareHintsDisabled Insufficient Node information: allocatable CPU or zone not specified on one or more nodes, addressType: IPv4 result=reject
AWS nodes seem to have the proper values in the nodes. GCP has the values also, but they are not "right" for the purposes of the EndpointSliceController:
event happened 38 times, something is wrong: ns/openshift-dns service/dns-default - reason/TopologyAwareHintsDisabled Unable to allocate minimum required endpoints to each zone without exceeding overload threshold (5 endpoints, 3 zones), addressType: IPv4 result=reject }
https://github.com/openshift/origin/pull/27666 will mask this problem (make it stop erroring in CI) but changes still need to be made in the product so end users are not subjected to these events.
