stable/pike of openstack-ansible-galera_server fails haproxy health check on rhel7

[Tim Way]

patch present in openstack-ansible-galera_server master as f2bfbd38513ac8d61ba4e02a4d5ef6cbbca259cc

centos7
stable/pike of openstack-ansible
stable/pike (8e831696cee8944f592449043838de97c0b001cb) of openstack-ansible-galera_server

In fact 8e831696cee8944f592449043838de97c0b001cb is the culprit of the change. It looks to set distribution specific sockets via a variable but the variable file for rhel7 (centos7) isn't updated until commit f2bfbd38513ac8d61ba4e02a4d5ef6cbbca259cc to accurately set the variable for rhel7 (centos7).

All os-* playbooks that need db tasks will fail if all galera servers/containers are centos7/rhel7 because haproxy will see them as down.

This patch will need to be pulled into stable/pike of openstack-ansible-galera_server and the sha will need to be updated in openstack-ansible (ansible-role-requirements.yml)

Clouds are unable to built if they contain centos7 galera servers so I'd think this should be a severe bug.

this review should fix that.

I verified this fixed the issue and it has now been merged into upstream stable/pike. I'll close the bug.
