Kolla-Ansible Overview
======================

The Kolla-Ansible is a deliverable project separated from Kolla project.

Kolla-Ansible deploys OpenStack services and infrastructure components
in Docker containers.

Kolla's mission statement is:

::

    To provide production-ready containers and deployment tools for operating
    OpenStack clouds.

Kolla is highly opinionated out of the box, but allows for complete
customization. This permits operators with little experience to deploy
OpenStack quickly and as experience grows modify the OpenStack
configuration to suit the operator's exact requirements.

Getting Started
===============

Learn about Kolla-Ansible by reading the documentation online
`docs.openstack.org <http://docs.openstack.org/developer/kolla-ansible/>`__.

Get started by reading the `Developer
Quickstart <http://docs.openstack.org/developer/kolla-ansible/quickstart.html>`__.

Directories
===========

-  ``ansible`` - Contains Ansible playbooks to deploy OpenStack services and
   infrastructure components in Docker containers.
-  ``contrib`` - Contains demos scenarios for Heat and Murano and a development
   environment for Vagrant
-  ``doc`` - Contains documentation.
-  ``etc`` - Contains a reference etc directory structure which requires
   configuration of a small number of configuration variables to achieve
   a working All-in-One (AIO) deployment.
-  ``tests`` - Contains functional testing tools.
-  ``tools`` - Contains tools for interacting with Kolla-Ansible.
-  ``specs`` - Contains the Kolla-Ansible communities key arguments about
