How to find the Chef environment in a recipe?

I want to run a cookbook_file resource only if the current environment is "dev". How can this be expressed?

The documentation suggests this:

In a recipe, a code block like this would be useful:

qa_nodes = search(:node,"chef_environment:QA")      
qa_nodes.each do |qa_node|                          
    # Do useful specific to qa nodes only
end

But I'm not sure that's what I want - the fact it's a loop seems wrong.

Solution 1:

Look in the chef_environment Ruby attribute (not a regular Chef attribute) on the node:

if node.chef_environment == "dev"
  # stuff
end

Solution 2:

another elegant way:

if ['production','development'].include? node.chef_environment
    #do something here
end
