Description Johnny Liu 2018-06-06 05:58:50 UTC 
Description of problem:
$ grep "openshift_dns_ip" inventory/hosts.example
# node.example.com openshift_dns_ip=172.30.0.1

Following hosts.example, setting openshift_dns_ip, but the setting take no any effect.

Version-Release number of the following components:
openshift-ansible-3.10.0-0.60.0.git.0.bf95bf8.el7.noarch

How reproducible:
Always

Steps to Reproduce:
1. setting openshift_dns_ip as the following:
openshift_dns_ip=172.30.0.1
2. trigger installation
3.

Actual results:
After installation, checking node config.
# grep dnsIP /etc/origin/node/node-config.yaml 
dnsIP: 0.0.0.0

The inventory setting does not take any effect.

Expected results:
the user setting dnsIP should be shown in node config file. 

Additional info:
The setting is working well in 3.9.
Comment 1 Scott Dodson 2018-06-06 12:09:34 UTC 
This is a configuration item that we need to hi-light as no longer being valid because it required per node configuration. We need to remove openshift_dns_ip from the codebase too.
