hiera¶

A hook which helps write hiera files to disk and creates the hiera.yaml to order them. This is typically used alongside the puppet hook to generate Hiera in a more composable manner.

Example:

ComputeConfig:
  type: OS::Heat::StructuredConfig
  properties:
    group: hiera
    config:
      hierarchy:
        - compute
      datafiles:
        compute:
          debug: true
          db_connection: foo:/bar
          # customized hiera goes here...

This would write out:

• An /etc/hiera.yaml config file with compute in the hierarchy.
• An /etc/puppet/hieradata/compute.json file loaded with the custom hiera data.
