Thought I'd share this in the hope of getting some feedback, this is still fairly embryonic but this Ansible lookup plugin performs data lookups against Jerakia, a flexible hierarchical data lookup tool that also integrates into Puppet/Hiera. More about Jerakia can be found at http://jerakia.ioAny feedback on the Ansible lookup plugin would be awesome, you can grab it at:
