Description Dan Winship 2020-12-14 22:11:48 UTC

In dual-stack clusters we need to pass dual node IPs to kubelet.

To verify:
- Install a dual-stack cluster
- do "oc get nodes -o yaml"
- confirm that all nodes list both an IPv4 and an IPv6 "InternalIP" address under .status.addresses

@yprokule @mcornea Can you guys help verifying it? Going to be a quick check. Thanks
