Director Components


Director Components

● Heat - Orchestration

● Ironic - Baremetal Provisioning

● Tuskar - WebAPI over Horizon

● TripleO - Heat templates


TripleO● TripleO ships with tools, utilities, and example templates for creating the templates that define the environment and

associated images to support the instantiation of such configurations.○ heat templates○ puppet elements○ diskimage-builder○ cloud configuration


Heat● Heat is used extensively within OSP director to provision and manage the

resources associated with deploying an OpenStack-based overcloud.● Ease of troubleshooting & managing overcloud deployed as stack .

Heat API

Cinder API Glance API Nova API Neutron API


Ironic

● Nova "baremetal driver" .● Uses power management details to boot baremetal

system in required environment .


Tuskar● Provides an API and management platform for defining and linking OpenStack node roles within a

TripleO deployment, via the notion of a 'plan'.● Provides a WebUI through an extension to Horizon, allowing administrators to deploy OpenStack

via a web console, monitor progress, and make pre-deployment configuration changes .
