You can absolutely use node attributes to drive your recipe... same
way you would use core Chef resource.

Your example would look more like this...

node['httpd']['services'].each do |service_name, val1, val2|
   httpd_service service_name do
     listen_ports val1
     run_user val2
   end
end

-s
