The Puppet Development Kit (PDK) is a package of development and testing tools that helps you create, validate, and test Puppet modules.

Note: Puppet (Perforce) ceased open-source maintenance of PDK at version 3.4.0. Newer versions are distributed from a protected repository requiring either a Puppet Forge API key or a Puppet Enterprise license ID to download; see Puppet’s PDK documentation for details. Documentation for the last open-source release is available in the pdk repository on GitHub.

Overview

PDK provides a standard set of tools and workflows for developing Puppet modules, including:

• Module scaffolding and structure validation
• Unit testing with rspec-puppet
• Acceptance testing with Litmus
• Metadata validation

Compatibility with OpenVox

OpenVox is compatible with PDK 3.4.0 and earlier for module development workflows. The last open-source release can be found in the pdk repository on GitHub.

Open source alternatives

The OpenVox community maintains tooling that replaces PDK workflows without requiring a commercial Puppet account:

• VoxBox — A container image maintained by Vox Pupuli that includes rspec-puppet, Litmus, RuboCop, and other testing gems. It is the recommended way to run unit and acceptance tests for OpenVox modules in CI and local development.
• jig — A Go-based reimplementation of PDK. Ships as a single static binary with no Ruby runtime dependency and supports module scaffolding, building, and releasing.
