Comment 1 Tim Bielawa 2017-07-10 19:38:18 UTC
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.

Comment 2 Tim Bielawa 2017-07-21 14:36:03 UTC
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

Comment 7 Scott Dodson 2017-08-14 15:08:23 UTC
https://github.com/openshift/openshift-ansible/pull/5081 backport to release-3.6 branch

Comment 9 Gan Huang 2017-08-24 10:27:56 UTC
Verified with openshift-ansible-

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.
