Puppet module to deploy Redis bundle for HA
This module is used by tripleo-heat-templates to configure and deploy Kolla-based Redis containers managed by pacemaker. We use short-lived containers that call pcs via puppet to create the needed pacemaker resources, properties and constraints. Co-Authored-By: Michele Baldesari <michele@acksyn.org> Partial-Bug: #1692924 Depends-On: I44fbd7f89ab22b72e8d3fc0a0e3fe54a9418a60f Depends-On: Ie9b7e7d2a3cec4b121915a17c1e809e4ec950e7f Change-Id: Ia1131611d15670190b7b6654f72e6290bf7f8b9e
