Including a Chef LWRP from another cookbook

Question

I wrote a small LWRP my app cookbook (trim_log), and it works. However, now I am trying to move this particular LWRP in to the commons cookbook so that my other cookbooks can also use it. The problem is that I cannot figure out how to load in the trim_log resource/provider in to any of the cookbooks, including my app cookbook.

├── app
│   ├── recipes
│       └── default.rb
├── commons
   ├── providers
   │   └── trim_log.rb
   └── resources
       └── trim_log.rb

I have defined the trim_log provider/resource in the commons cookbook. Now I wish to use this trim_log provider/resource in the app cookbook. How can I make it available there?

Answer 1

I believe you need to:

• Declare in the app/metadata.rb that you depend on the commons cookbook.
• Refer to the resource as commons_trim_log in app/recipes/default.rb.

I didn't realize you had to specify the dependency of commons in the app cookbook's metadata.rb. That fixed it, thanks a lot! – Connotative

If you are working with multiple cookbooks, you should check out Berkshelf and Foodcritic, both of which will push you to write better metadata.rb files. – Ligurian
