State of the Onion for August 11 2015-08-11

It has been a few months since my last status update and things are coming along nicely. As before I would like to again thank all my sponsors and supporters for making this work possible!

Support Cookbooks

Both Poise and Halite have seen feature releases. Mostly this has been support for Chef 12.4+ as well as some minor fixes and helpers. Lots of good stuff, but mostly relevant to me as the author of all this.

Application Cookbooks

The application cookbooks have moved forward quite a bit. The four core cookbooks (application, app_git, app_ruby, app_python) are all minimally feature complete. This means that they support all the resources I want before release, but some of those resources are intentionally minimalistic. With service resources like thin and gunicorn they support the most common options like port as resource properties, with creating a configuration file as a fall-back for less frequently used options. I could use help in determining which options for each tool are common enough to warrant being exposed directly in the DSL.

Example recipes are available covering four of the most common web frameworks:

Language Cookbooks

Both poise-python and poise-ruby are feature complete and ready for release. They support installing the Ruby or Python runtime from a variety of sources, handle command execution for the language, and have resources to manage language-specific package installs.

A lot of the shared code between them as also been refactored to a set of shared mixins in a new poise-languages cookbook.

What’s Next

Over the next few days I’m going to continue to improve the documentation for all these cookbooks. Reference documentation for all the new resources is in places already, but the introductory guides need more work as do porting guides for those upgrading from the current versions of the cookbooks.

I want to get all the previously mentioned cookbooks shipped so people can start using them before I move on to creating new ones. I’m hopeful that shortly after the big x.0.0 releases there will be a flurry of smaller feature releases as people point out options and patterns common enough to be promoted to full DSL support instead of being in configuration files.

After that the next big application type on my list is server-side JavaScript, and then smaller helpers for Java, Go, and Erlang. Also on the smaller side of things is some exploratory work on a general-purpose service discovery API for Chef recipes.


The application stacks for Ruby and Python will be released very soon. If you still have not locked your dependencies, expect your Chef runs to break.

I would love more help from people deploying apps on Thin, Unicorn, Gunicorn, and Celery in working out what options are common enough to be included in the DSL.


If anyone has any questions on any of these cookbooks or my future plans for them please don’t hesitate to get in contact with me. You can reach me at or any of the methods on my contact page.
