Puppet Class: hiera
- Inherits:
- hiera::params
- Defined in:
- manifests/init.pp
Summary
This class handles installing the hiera.yaml for Puppet's use. Creates either /etc/puppet/hiera.yaml or /etc/puppetlabs/puppet/hiera.yaml in set hiera version and links /etc/hiera.yaml to it. Creates $datadir (if $datadir_manage == true).Overview
