Configuring puppetdb as a hiera_backend

[divansantana]

One can configure puppetdb as a hiera_backend as per https://github.com/dalen/puppet-puppetdbquery#hiera-backend

However I'm not sure that it's currently possible to do this using this module as it expects a hash.

You'd expect this to work like so:

puppet::profile::master::hiera_backends:
  yaml:
    datadir: "/etc/puppet/environments/%{environment}/hiera"
  eyaml:
    datadir: "/etc/puppet/environments/%{environment}/hiera"
  puppetdb:

However breaks with:

Error: Failed to parse template puppet/hiera.yaml.erb:
  Filepath: /root/modules/puppet/templates/hiera.yaml.erb
  Line: 15
  Detail: undefined method `keys' for nil:NilClass
 at /root/modules/puppet/manifests/master/hiera.pp:22 on node node.example.co.za

Unless one can use this syntax:

puppet::profile::master::hiera_backends:
  puppetdb:
    datasource: data

I'll test this out and see if it works.
