[chef] Wrapper cookbooks, templates, lazy

[Justin Dossey < >]

I ran into an interesting one today.

If you're wrapping a (community) cookbook and your wrapper needs lazy {} to move evaluation of something to the execute phase, the #resources method doesn't work.

Example

Cookbook foo, recipes/default.rb

file '/tmp/foo.txt' do

   owner node['foo']['user']

end

Cookbook bar, recipes/default.rb

include_recipe 'foo::default'

user 'new_user'

node.override['foo']['user'] = 'new_user'

# this doesn't work:

resources(file: '/tmp/foo.txt').owner( lazy { node['foo']['user'] })

# you have to do this:

file '/tmp/foo.txt' do

  owner lazy { node['foo']['user'] }
end

Ideally, I'd be able to do something like this:

resources(file: '/tmp/foo.txt').lazy(:owner)
