+Infrared Intance-ha Plugin Playbook
+====================================
+
+This Plugin deploys Instance-Ha on OpenStack using InfraRed
+
+The Tasks in infrared_instance-ha_plugin_main.yml, along with the
+plugin.spec at tripleo-quickstart-utils/plugin.spec provide support
+for running this repo's roles and playbooks as an Infrared plugin.

+ that aims to provide an easy-to-use CLI for Ansible based projects and 
+ OpenStack deployment.

+two OpenStack High-Availability features:  
+
+ [instance-ha](https://github.com/redhat-openstack/tripleo-quickstart-utils/tree/master/roles/instance-ha)
+
+ [stonith-config](https://github.com/redhat-openstack/tripleo-quickstart-utils/tree/master/roles/stonith-config)
