Ansible
Ansible is a radically simple IT automation system that offers a wide range of capabilities. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. With Ansible, complex tasks like zero-downtime rolling updates with load balancers become effortless. For more information, visit the Ansible website.
Design Principles
Ansible is built on the following design principles:
- Simplicity: It has an incredibly straightforward setup process with a minimal learning curve.
- Efficiency: It manages machines quickly and concurrently, allowing for optimal performance.
- Agentless: Ansible leverages the existing SSH daemon, eliminating the need for custom agents and additional open ports.
- Human-friendly: Infrastructure can be described using a language that is both machine and human-readable.
- Security: Ansible prioritizes security, making it easy to audit, review, and rewrite content.
- Instant Management: New remote machines can be managed instantly without the need for any software bootstrapping.
- Ease of Use: Ansible aims to be the easiest IT automation system to use, ever.
Use Ansible
You can install a released version of Ansible with pip
or a package manager. See our installation guide for details on installing Ansible on a variety of platforms.
Power users and developers can run the devel
branch, which has the latest features and fixes, directly. Although it is reasonably stable, you are more likely to encounter breaking changes when running the devel
branch. We recommend getting involved in the Ansible community if you want to run the devel
branch.
Get Involved
- Read the 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.
- Join a Working Group, an organized community devoted to a specific technology domain or platform.
- Submit a proposed code update through a pull request to the
devel
branch. - Talk to us before making larger changes to avoid duplicate efforts. This not only helps everyone know what is going on but also saves time and effort if we decide some changes are needed.
- For a list of email lists, IRC channels, and Working Groups, see the Communication page.
Coding Guidelines
We document our Coding Guidelines in the Developer Guide. We particularly suggest you review:
Branch Info
- The
devel
branch corresponds to the release actively under development. - The
stable-2.X
branches correspond to stable releases. - Create a branch based on
devel
and set up a dev environment if you want to open a PR. - See the Ansible release and maintenance page for information about active branches.
Roadmap
Based on team and community feedback, an initial roadmap will be published for a major or minor version (ex: 2.7, 2.8). The Ansible Roadmap page details what is planned and how to influence the roadmap.
