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 and Ansible 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
Learn about Kolla by reading the documentation online docs.openstack.org.
Get started by reading the Developer Quickstart.
Docker images
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 and implement an Ansible roles for many but not all of them.
You can view the available images on Docker Hub or with the Docker CLI:
$ sudo docker search kollaOpenStack services
Kolla provides images to deploy the following OpenStack projects:
- Aodh
- Barbican
- Bifrost
- Ceilometer
- Cinder
- CloudKitty

- Designate
- Glance
- Gnocchi
- Heat
- Horizon

Infrastructure components
Kolla provides images to deploy the following infrastructure components:
- Ceph implementation for Cinder, Glance and Nova
- collectd, InfluxDB, and Grafana for performance monitoring.
- Elasticsearch and

Kibana to search, analyze, and visualize log messages.
- HAProxy and Keepalived for high availability of services and their endpoints.
- Heka A distributed and scalable logging system for OpenStack services.
- MariaDB and Galera Cluster for highly available MySQL databases
- MongoDB as a database backend for Ceilometer and Gnocchi
- Open vSwitch and Linuxbridge backends for Neutron
- RabbitMQ as a messaging backend for communication between services.
