Directory /home/ansible/.ansible and file /var/log/kolla/ansible.log are not created by default in toolbox image, so when ceph enabled, the directory and file will be created with user 'root' instead of user 'ansible' after running bootstrap osds because it using sudo when bootstraping osds, this will cause permission denied issue for other commands not using sudo. Fixes this issue by initializing ansible by running 'ansible localhost --version' using user 'ansible' TrivialFix Change-Id: Ibac3f98b3b72cbe287ee1d3a69ed9cea7ae3cd9e
Kolla Overview
The Kolla project is a member of the OpenStack Big Tent Governance. Kolla's mission statement is:
Kolla provides 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.
Kolla provides images to deploy the following OpenStack projects:
- Aodh
- Ceilometer
- Cinder
- Designate
- Glance
- Gnocchi
- Heat
- Horizon
- Ironic
- Keystone
- Magnum
- Manila
- Mistral
- Murano
- Nova
- Neutron
- Swift
- Tempest
- Trove
- Zaqar
As well as these infrastructure components:
- Ceph implementation for Cinder, Glance and Nova
- Openvswitch and Linuxbridge backends for Neutron
- MongoDB as a database backend for Ceilometer and Gnocchi
- RabbitMQ as a messaging backend for communication between services.
- HAProxy and Keepalived for high availability of services and their endpoints.
- MariaDB and Galera for highly available MySQL databases
- Heka A distributed and scalable logging system for openstack services.
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 deployment for many but not all of them.
You can view the available images on Docker Hub or with the Docker CLI:
$ sudo docker search kollaDirectories
- ansible - Contains Ansible playbooks to deploy Kolla in Docker containers.

- dev/heat - Contains an OpenStack-Heat based development environment.
- dev/vagrant - Contains a vagrant VirtualBox/Libvirt based development environment.
- doc - 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 - 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.
