This ansible module for docker-compose allows for idempotency. I have submitted a pull request upstream to ansible-modules-extra to include this new module. When/if the module is accepted upstream if can be removed from the local module library. The two playbooks have been updated to use this module. The database data container does not support idempotency due to the fact that it exists instead of sleeps. Therefore each time `docker-compose up` is called, it will start the container and register a change. The message-broker does not have this issue and will remain unchanged even repeatedly running these playbooks. Due to the use of a special branch of docker-compose provided by sdake, this module requires at least docker-compose==1.2.0rc1 Change-Id: If1644eaa3bff0c2a007fa2d479a95bea941945f6
Kolla Overview
The Kolla project is part of the OpenStack TripleO effort, focused on deploying OpenStack services using Docker containers. The initial system spec provides additional details of Kolla and the use cases it addresses.
Getting Started
Deployment on bare metal is a complex topic which is beyond the scope of the project at this time. An environment to simplify the deployment of a single or multi-node Kolla cluster is required for development purposes. As a result, a Heat template has been created for deploying a Kolla cluster to an existing OpenStack cloud.
Docker Images
The Docker images are built by the Kolla project maintainers. A detailed process for contributing to the images can be found here. Images reside in the Docker Hub Kollaglue repo.
The Kolla developers build images in the kollaglue namespace for the following services:
- Glance
- Heat
- Keystone
- Mariadb
- Nova
- Rabbitmq
- Neutron
- Mongodb
- Ceilometer
- Zaqar
- Horizon
$ sudo docker search kollaglue
A list of the upstream built docker images will be shown.
Directories
- docker - contains artifacts for use with docker build to build appropriate images
- compose - contains the docker-compose files defining the container sets
- tools - contains different tools for interacting with Kolla
- devenv - A collection of tools and resources for managing a Kolla development environment.
