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
===============

Please get started by reading the `Developer
Quickstart <https://github.com/stackforge/kolla/blob/master/docs/dev-quickstart.rst>`__
followed by the `Ansible Deployment
Guide <https://github.com/stackforge/kolla/blob/master/docs/ansible-deployment.rst>`__.

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 <https://github.com/stackforge/kolla/blob/master/docs/image-building.rst>`__.
Images reside in the Docker Hub `Kollaglue
repo <https://registry.hub.docker.com/repos/kollaglue/>`__.

The Kolla developers build images in the kollaglue namespace for the
following services for every tagged release and implement Ansible
deployment for them:

-  Ceilometer
-  Cinder
-  Glance
-  Haproxy
-  Heat
-  Horizon
-  Keepalived
-  Keystone
-  Mariadb + galera
-  Mongodb
-  Neutron (linuxbridge or neutron)
-  Nova
-  Openvswitch
-  Rabbitmq

::

    $ sudo docker search kollaglue

A list of the upstream built docker images will be shown.

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

-  ansible - Contains Anible playbooks to deploy Kolla in Docker
   containers.
-  compose - Contains the docker-compose files serving as a compose
   reference. Note compose support is removed from Kolla. These are for
   community members which want to use Kolla container content without
   Ansible.
-  demos - Contains a few demos to use with Kolla.
-  devenv - Contains an OpenStack-Heat based development environment.
-  docker - Contains a normal Dockerfile based set of artifacts for
   building docker. This is planned for removal when docker\_templates
   is completed.
-  docs - 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.
-  docker\_templates - Contains jinja2 templates for the docker build
   system.
-  tools - Contains tools for interacting with Kolla.
-  specs - Contains the Kolla communities key arguments about
   architectural shifts in the code base.
-  tests - Contains functional testing tools.
-  vagrant - Contains a vagrant VirtualBox-based development
   environment.
