Adding Hiera data to your Puppet repo

Let's add some example Hiera data to your Puppet repo and see what we can do with it. The following steps will take you through this process:

1. Run the following commands to install your per-environment Hiera config file:

   cd /etc/puppetlabs/code/environments/production
   sudo cp /vagrant/examples/hiera_minimal.config.yaml hiera.yaml
   

2. Create your data directory for the data files to live in:

   sudo mkdir data
   

3. Run the following command to install the example Hiera data file in your data directory (make sure you copy it exactly as shown; the file needs to end up named common.yaml):

   sudo cp /vagrant/examples/hiera_sample.yaml data/common.yaml

   sudo puppet apply -e "notice(lookup('test'))"
