Radically simple IT automation

Project description

PyPI version Docs badge Chat badge Build Status


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.

You can find installation instructions here for a variety of platforms.

Most users should probably install a released version of Ansible from pip, a package manager or our release repository. Officially supported 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 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 to the devel branch.

  • Feel free to talk to us before making larger changes to avoid duplicate efforts. This not only helps everyone know what’s going on, it also helps save time and effort if we decide some changes are needed.

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.

  • The stable-2.x branches exist for current releases.

  • Various release-X.Y branches exist for previous releases.

  • For information about the active branches see the Ansible release and maintenance page.

  • We’d love to have your contributions, read the Community Guide for notes on how to get started.


Based on team and community feedback, an initial roadmap will be published for a major or minor version (ex: 2.0, 2.1). Subminor versions will generally not have roadmaps published.

The Ansible Roadmap page details what is planned and how to influence the roadmap.
