Kolla Overview

The Kolla project is a member of the OpenStack Big Tent Governance.

Kolla's mission statement is:

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

Kolla provides Docker containers, Ansible playbooks to deploy OpenStack on baremetal or virtual machine, and Kubernetes templates to deploy OpenStack on Kubernetes to meet Kolla's mission.

Kolla has out of the box defaults for a working basic deployment, and also implements complete customization. This model permits operators with minimal experience to deploy OpenStack quickly and as the operator's experience grows modify the OpenStack configuration to suit the operator's exact requirements.

Getting Started

Learn about Kolla by reading the documentation online docs.openstack.org.

Get started by reading the Developer Quickstart.

The Kolla Repository

The Kolla repository is one of three deliverables of the OpenStack Kolla project. The three deliverables that make up the Kolla project are:

The Docker images are built by the Kolla project maintainers. A detailed process for contributing to the images can be found in the image building guide.

The Kolla developers build images in the kolla namespace for every tagged release.

You can view the available images on Docker Hub or with the Docker CLI:

$ sudo docker search kolla
