Masakari - Virtual Machines High Availability

Overview

Masakari provides Instances High Availability Service for OpenStack clouds by automatically recovering failed Instances. Currently, Masakari can recover KVM-based Virtual Machine(VM)s from failure events such as VM process down, provisioning process down, and nova-compute host failure. Masakari also provides an API service to manage and control the automated rescue mechanism.

Kolla deploys Masakari API, Masakari Engine and Masakari Monitor containers which are the main Masakari components only if enable_masakari is set in /etc/kolla/globals.yml. By default, both the Masakari Host Monitor and Masakari Instance Monitor containers are enabled. The deployment of each type of monitors can be controlled individually via enable_masakari_instancemonitor and enable_masakari_hostmonitor.
