PennyworthThis tool was uploaded to GitHub just last night. It's a continuous packaging system built around Chef, Jenkins and the FPM packaging tool.
Based upon the principles of continuous integration, pennyworth will help you build assets for any software you use and provides a reasonable means to distribute it throughout your nodes. By using a well tested package management system under the hood for deployment, you can easily roll back versions and manage node level conflicts.
Jenkins can be configured to search for feature branches, for advanced workflows. We’ve included some examples for basic branch tracking.
Many example data bags are included that show how to test, build and package a variety of projects, including Ruby and Clojure projects. --Darrin Eden
It supports Vagrant and there are several related Chef cookbooks.
BlueprintBlueprint reverse-engineers servers and can convert 'blueprints' to either Chef or Puppet.
Blueprint looks inside popular package managers, finds changes you made to configuration files, and archives software you built from source. It runs on Debian- and RPM-based Linux distros with Python >= 2.6 and Git >= 1.7.
Blueprint I/O pushes and pulls blueprints to and from a Blueprint I/O Server, making it easy to use blueprints anywhere. DevStructure provides a free Blueprint I/O Server at https://devstructure.com, which stores blueprints in Amazon S3. Alternatively, you can build your own backend server implementing the Blueprint I/O API. --Richard Crowley
