Make decisions in your Chef recipe based on the version of the Chef Client

There are times when you have to make a decision in your Chef recipe, based on the version of the Chef Client installed on the node.

There are two ways to get the version of the installed Chef Client:

Chef::VERSION

node['chef_packages']['chef']['version']

To make a decision based on the installed Chef Client version

if ( Chef::VERSION.to_f >= 14.0 )
  puts "Version 14.0 or higher"
else
  puts "Before version 14.0"
end
