Help with Chef::CookbookLoader for 0.7.16


#1

Hi!

I’m trying to develop a application that uses Chef for deploying Software.
Because of that, I need to get all available cookbooks. I found the
CookbookLoader-class but it seems that it doesn’t work.
When I try

c_list = Chef::CookbookLoader.new

I can’t access any cookbook. Trying to get the apache2 cookbook I get the error

/usr/lib/ruby/gems/1.8/gems/chef-0.7.16/lib/chef/cookbook_loader.rb:126:in
`[]’: Cannot find a cookbook named apache2; did you forget to add metadata to a
cookbook? (http://wiki.opscode.com/display/chef/Metadata) (ArgumentError)

but I have no idea why it isn’t working.

Any suggestions?

Ohai!
Hard to say without seeing more of your code, but my first guess is
that you need to setup Chef::Config and make sure the :cookbook_path
config option is set.

If you’re just doing require 'chef' you should get Chef::Config
loaded so you could just do Chef::Config[:cookbook_path] =
’/your/cookbook/path’ before running CookbookLoader#load_cookbooks.

Hi Daniel!

That was exactly the problem. I was wondering that your proposal worked
because I already checked if the cookbook_path was set.

Thanks for your help! :slight_smile:
