RDO-Manager Introduction

RDO-Manager is an OpenStack Deployment & Management tool for RDO. It is based on OpenStack TripleO project and its philosophy is inspired by SpinalStack <http://spinal-stack.readthedocs.org/en/ latest/>.

The tooling allows you to deploy a management node ("undercloud") which contains the services required to then deploy your OpenStack environment ("overcloud")

RDO manager provides semi-automated configuration of your undercloud environment, after which it is possible to deploy an overcloud containing your desired number of overcloud resource nodes (using either UI or CLI interfaces).

Overcloud resource nodes may be independently scaled, and support exists for the following roles:

Controller

The Controller nodes contain the OpenStack API services and associated dependencies.

Compute

The Compute nodes contain the Nova compute (hypervisor) components.

Storage

Optional Storage roles exist which allow you to scale Ceph, Swift or LVM based Cinder storage independently of the controller.
