Ansible
*******
Ansible is a radically simple IT automation system. It handles
configuration-management, application deployment, cloud provisioning,
ad-hoc task-execution, and multinode orchestration -- including
trivializing things like zero-downtime rolling updates with load
balancers.
Read the documentation and more at https://ansible.com/
You can find installation instructions
`here <https://docs.ansible.com/intro_getting_started.html>`_ for a
variety of platforms.
Most users should probably install a released version of Ansible from ``pip``, a package manager or
our `release repository <https://releases.ansible.com/ansible/>`_. `Officially supported
<https://www.ansible.com/ansible-engine>`_ builds of Ansible are also available. Some power users
run directly from the development branch - while significant efforts are made to ensure that
``devel`` is reasonably stable, you're more likely to encounter breaking changes when running
Ansible this way.
Design Principles
=================
* Have a dead simple setup process and a minimal learning curve
* Manage machines very quickly and in parallel
* Avoid custom-agents and additional open ports, be agentless by
leveraging the existing SSH daemon
* Describe infrastructure in a language that is both machine and human
friendly
* Focus on security and easy auditability/review/rewriting of content
* Manage new remote machines instantly, without bootstrapping any
software
* Allow module development in any dynamic language, not just Python
* Be usable as non-root
* Be the easiest IT automation system to use, ever.
Get Involved
============
* Read `Community
Information <https://docs.ansible.com/community.html>`_ for all
kinds of ways to contribute to and interact with the project,
including mailing list information and how to submit bug reports and
code to Ansible.
* All code submissions are done through pull requests. Take care to
make sure no merge commits are in the submission, and use
``git rebase`` vs ``git merge`` for this reason. If submitting a
large code change (other than modules), it's probably a good idea to
join ansible-devel and talk about what you would like to do or add |

know what's going on, it also helps save time and effort if we decide
some changes are needed.
* Users list:

Branch Info
===========
* Releases are named after Led Zeppelin songs. (Releases prior to 2.0
were named after Van Halen songs.)
* The devel branch corresponds to the release actively under
development.
* Various release-X.Y branches exist for previous releases.
* We'd love to have your contributions, read `Community
Information <https://docs.ansible.com/community.html>`_ for notes on
how to get started.
