From 826b27153146c71e5349a0f7594fbd98997d6115 Mon Sep 17 00:00:00 2001 From: Emilien Macchi Date: Thu, 5 May 2016 11:41:21 -0400 Subject: Add loadbalancer profile for ha & non-ha The profile contains Puppet classes to deploy loadbalancer services (HAproxy & Keepalived) for ha & non-ha scenarios. A future iteration will split HAproxy & keepalived, but for now, we just want to move out the code from THT to puppet-tripleo.
