I've been looking at this one today. Attempting to set up an environment to test in which enables the atomic-openshift-master-controllers service. No branch yet for the work.
Working on this issue in here: https://github.com/openshift/openshift-ansible/pull/4806
Testing initiated just now.
Moving to POST until we merge this into release-3.6 branch
https://github.com/openshift/openshift-ansible/pull/5081 backport to release-3.6 branch
Verified with openshift-ansible-188.8.131.52.7-2.git.0.340aa2c.el7.noarch.rpm
The internal ips of etcd hosts are added correctly by default to NO_PROXY in /etc/sysconfig/atomic-openshift-master-controllers, and builds and deployments work well.
