when I had those before (but even if I didn't, they would get created):
~ oc get configmaps designate-mdns-ip-map -o json | jq -r '.data'; oc get configmaps designate-bind-ip-map -o json | jq -r '.data'
{
"mdns_crc-vlf7c-master-0": "172.28.0.97"
}
{
"bind_address_0": "172.28.0.98",
"bind_address_1": "172.28.0.99"
}

and that configmap, which was created in the current PR:
