Kolla Overview
The Kolla project is a member of the OpenStack `Big Tent
Governance <http://governance.openstack.org/reference/projects/index.html>`__.
Kolla's mission statement is:
Kolla provides production-ready containers and deployment tools for
operating OpenStack clouds.
Kolla provides `Docker <http://docker.com/>`__ containers and
`Ansible <http://ansible.com/>`__ playbooks to meet Kolla's mission.
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

Docker Images
The `Docker images <https://docs.docker.com/userguide/dockerimages/>`__
are built by the Kolla project maintainers. A detailed process for
contributing to the images can be found in the `image building
guide <http://docs.openstack.org/developer/kolla/image-building.html>`__.
The Kolla developers build images in the `kolla` namespace for every tagged
release and implement an Ansible deployment for many but not all of them.
You can view the available images on `Docker Hub
<https://hub.docker.com/u/kolla/>`__ or with the Docker CLI::
$ sudo docker search kolla
