cookbook_versions

This cookbook examines all of the cookbooks in a node's run_list and extracts the cookbook versions. These are saved into node attributes under the 'cookbook_versions' key, like so:

cookbook_versions => {
  "cookbook_versions_test": "0.1.0",
  "cookbook_versions": "0.1.0"
}

NOTE: This cookbook_versions resource should be run at the end of a chef-client run, or else recipes may modify the run_list and that won't be reflected in the node attributes.

Usage

You can use the resource directly, or include the default recipe which simply calls the resource

cookbook_versions 'whatever'

What is included

By default, cookbook_versions includes only cookbooks that have a recipe in the run_list.
This will not include cookbooks that provide resources but don't have recipes.
You can change this behavior by either using the cookbook_versions::all recipe instead of the default recipe in your run_list, or by passing the all_cookbooks true attribute to the resource:

cookbook_versions 'whatever' do
  all_cookbooks true
end
