Kolla Overview

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

The `Docker images <https://docs.docker.com/storage/storagedriver/>`__
|
|
are built by the Kolla project maintainers. A detailed process for
|
|
contributing to the images can be found in the `image building
|
|
guide <https://docs.openstack.org/kolla/latest/admin/image-building.html>`__.
|
|
|
|
The Kolla developers build images in the `kolla` namespace for every tagged
|
|
release.
|
|
|
|
You can view the available images on `Docker Hub
|
|
<https://hub.docker.com/u/kolla/>`__ or with the Docker CLI::
