Description Damien Ciabrini 2018-03-27 21:01:45 UTC

Description of problem:
In non-containerized overcloud, we used to have access to HAProxy's stats socket, which allows to retrieve statistics about proxied traffic, current state of backends...

In OSP12, this stat socket is not exposed to the host because there is no bind mount configured at container creation.

This stats socket should be re-exposed in OSP13, and major upgrade from OSP12 to OSP13 should update the pacemaker bundles accordingly.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Deploy OSP12
2. Upgrade to OSP13
3.

Actual results:
no stats socket accessible from the host

Expected results:
stats socket should be available in /var/lib/haproxy/stats

Additional info:
this bz includes fixes for tripleo-heat-templates and and puppet-tripleo
