[chef] Cookbook versions on node

[Peter Donald < >]

Hi,

I would like to enforce certain cookbook version requirements on
cookbooks in different environments from within a recipe.

i.e. All cookbooks on "production" environment must have an even minor
version. (i.e. 10.0.2 is valid but 10.0.3 is not). I also want to
require that cookbooks be locked or not. (i.e. cookbook referenced in
production environments must be frozen).

Doing something like

node.run_list.expand(node.chef_environment).recipes.with_versions.each
do |recipe|
  p recipe
end

will only include the versions if they have been explicitly set and
will not allow me to check to see if the version is locked.

Anyone have a good idea how to do this?
