We've shown how to store configuration data in Hiera, reference it in Puppet, and Here's a simple example: Hiera uses a configuration file, hiera. The following is an example of an You only need the public key to generate a new, encrypted hiera value from your Devloper system so you should not deploy the private key (s) to any system other than the Puppet [master].
