Description Dan Winship 2020-10-16 00:53:00 UTC

Description of problem:
We had not yet updated cluster-kube-apiserver-operator to pass both service CIDRs to kube-apiserver when the cluster was dual-stack

Steps to Reproduce:
1. Deploy dual-stack cluster
2. Try to create a service with `ipFamily: IPv6`

Actual results:
error

Expected results:
an IPv6 service

I can verify this:

# oc rsh -n openshift-kube-apiserver kube-apiserver-master-0
sh-4.4# jq . < /etc/kubernetes/static-pod-resources/configmaps/config/config.yaml | grep servicesSubnet
  "servicesSubnet": "172.30.0.0/16,fd02::/112",
