Imagine you have written a great cookbook for your Ubuntu node and now you need to run it on that CentOS server. Ouch! It will most probably fail miserably. Package names might be different and configuration files are in different places.
Luckily, Chef provides you with a host of features to write cross-platform cookbooks. With just a few simple commands, you can make sure that your cookbook adapts to the platform that your node is running on. Let's take a look at how to do this...
Make sure you have a cookbook called
my_cookbook, and that the
run_list of your node includes
my_cookbook, as described in the Creating and using cookbooks recipe in Chapter 1, Chef Infrastructure.
