Puppet, an automated administrative engine for your Linux, Unix, and Windows systems, performs administrative tasks (such as adding users, installing packages, and updating server configurations) based on a centralized specification.
Documentation for Puppet and related projects can be found online at the Puppet Docs site.
To install an open source release of Puppet, see the installation guide on the docs site.
If you need to run Puppet from source as a tester or developer, see the running from source guide on the docs site.
Developing and Contributing
We'd love to get contributions from you! For a quick guide to getting your system setup for developing take a look at our Quickstart Guide. Once you are up and running, take a look at the Contribution Documents to see how to get your changes merged in.
For more complete docs on developing with puppet you can take a look at the rest of the developer documents.
See LICENSE file.
We use semantic version numbers for our releases, and recommend that users stay as up-to-date as possible by upgrading to patch releases and minor releases as they become available.
Bugfixes and ongoing development will occur in minor releases for the current major version. Security fixes will be backported to a previous major version on a best-effort basis, until the previous major version is no longer maintained.
For example: If a security vulnerability is discovered in Puppet 4.1.1, we would fix it in the 4 series, most likely as 4.1.2. Maintainers would then make a best effort to backport that fix onto the latest Puppet 3 release.
Long-term support, including security patches and bug fixes, is available for commercial customers. Please see the following page for more details:
