About OpenStack-Ansible
OpenStack-Ansible (OSA) uses the Ansible IT automation engine to deploy an OpenStack environment on Ubuntu, Debian and CentOS.
For isolation and ease of maintenance, you can install OpenStack components into machine containers.
The OpenStack-Ansible manifesto
All the design considerations (the container architecture, the ability to override any code, the network considerations, etc.) of this project are listed in our :dev_docs:architecture reference <reference/architecture/index.html>.
Why choose OpenStack-Ansible?
- Supports the major Linux distributions Ubuntu, CentOS, Debian.
- Supports the major CPU architectures x86, ppc64, s390x (WIP).
- Offers automation for upgrades between major OpenStack releases.
- Uses OpenStack defaults for each of the project roles, and provides extra wiring and optimised configuration when combining projects together.
- Does not implement its own DSL, and uses wherever possible Ansible directly. All the experience acquired using Ansible can be used in openstack-ansible, and the other way around.
- You like to use reliable, proven technology. We try to run OpenStack with a minimum amount of packages that are not provided by distributions or the OpenStack community. Less dependencies and distribution tested software make the project more reliable.
- You want to be able to select how to deploy on your hardware: deploy partially on metal, fully on metal, or fully in machine containers.
When not to choose OpenStack-Ansible?
- If your company is already invested with other configuration management systems, Puppet or Chef, and does not want to use Ansible we recommend re-using your knowledge and experimenting with a different OpenStack deployment project.
- You want to deploy OpenStack with 100% application containers. We currently support machine containers, with lxc and we will support systemd-nspawn in the future (WIP). If you want to go 100% Docker, there are other projects in the OpenStack community that can help you.
