Doc Type: Bug Fix
Doc Text:
Cause: Undesired dns IP is selected by openshift service in case of multiple NICs. Consequence: DNS requests failed to work from pod. Fix: Create sane defaults for DNS IP and it follows the similar pattern used by kubelet to fetch routable node IP. Result: DNS requests from pod works as expected.
