From 92697b653ebfcb9d3e0af1e470cd0276b8dca04f Mon Sep 17 00:00:00 2001 From: Damien Ciabrini Date: Fri, 2 Jun 2017 14:50:02 -0400 Subject: Puppet module to deploy cinder-backup bundle for HA This module is used by tripleo-heat-templates to configure and deploy Kolla-based cinder-backup containers managed by pacemaker. We use short-lived containers that call pcs via puppet to create the needed pacemaker resources, properties and constraints.
