The Kolla project is a member of the OpenStack Governance.
Kolla's mission statement is:
To provide tools to create production-ready containers and to provide deployment tools for operating OpenStack clouds.
Kolla provides tools to create containers that can be run under either Docker or Podman <https://podman.io/>, as well as Ansible playbooks to deploy OpenStack on baremetal or virtual machine 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.
Learn about Kolla by reading the documentation online Kolla.
Get started by reading the Kolla Ansible Developer Quickstart.
The Kolla repository is one of four deliverables of the OpenStack Kolla project. The four deliverables that make up the Kolla project are:
| Deliverable | Repository |
|---|---|
| kolla | https://opendev.org/openstack/kolla |
| kolla-ansible | https://opendev.org/openstack/kolla-ansible |
| ansible-collection-kolla | https://opendev.org/openstack/ansible-collection-kolla |
| kayobe | https://opendev.org/openstack/kayobe |
The Kolla developers publish images in the Quay.io openstack.kolla namespace for every tagged release. You can view the available images on Quay.io.
Warning
Kolla(-ansible) defaults to using these images in order to ease testing and
demonstration setups, but they are not intended to be used beyond this.
In particular, they do not undergo any security scrutiny. If you intend to
deploy Kolla for production purposes, you are advised to create and curate your
own set of images using the kolla tool.
Kolla provides images to deploy the following OpenStack projects:
- Aodh
- Barbican
- Bifrost
- Blazar
- Ceilometer
- Cinder
- CloudKitty
- Cyborg
- Designate
- Glance
- Heat
- Horizon
- Ironic
- Keystone
- Kuryr
- Magnum
- Manila
- Masakari
- Mistral
- Neutron
- Nova
- Octavia
- Placement
- Skyline (APIServer and Console)
- Tacker
- Trove
- Watcher
- Zun
Kolla provides images to deploy the following infrastructure components:
- Collectd, InfluxDB, and Grafana for performance monitoring.
- Cron for log rotation.
- Etcd a distributed key value store that provides a reliable way to store data across a cluster of machines.
- Fluentd as an open source data collector for unified logging layer.
- Gnocchi a time-series storage database.
- Corosync and Pacemaker for HAcluster.
- HAProxy and Keepalived for high availability of services and their endpoints.
- MariaDB and Galera Cluster for highly available MySQL databases.
- Memcached a distributed memory object caching system.
- MariaDB Backup A tool which provides a method of performing a hot backup of your MySQL data while the system is running.
- Open vSwitch for use with Neutron.
- Opensearch to search, analyze, and visualize log messages.
- Prometheus an open-source systems monitoring and alerting toolkit originally built at SoundCloud.
- RabbitMQ as a broker messaging back end for communication between services.
- Valkey Sentinel provides high availability for valkey along with collateral tasks such as monitoring, notification and acts as configuration provider for clients.
- Telegraf as a plugin-driven server agent for collecting & reporting metrics.
