Hiera Example

This example really just demonstrates a simple approach to pulling common data out of your manifests and into Hiera.

What

For this example we're just creating a single instance and security group, using AMI and region details stored in the hiera YAML file at hieradata/common.yaml.

             +-------------+
             | +---------+ |
             | |         | |
 hiera-test  | | hiera-1 | |
             | |         | |
             | +---------+ |
             +-------------+

Feel free to change the details in the YAML file to other AMIs and regions.

How

With the module installed as described in the README, from this directory run:

puppet apply init.pp --test --hiera_config hiera.yaml

This should create an instance and security group. You can delete them with the puppet resource commands when done.

puppet resource ec2_instance hiera-1 region=us-west-1 ensure=absent puppet resource ec2_securitygroup hiera-test region=us-west-1 ensure=absent

Discussion

This example uses explicit calls to the Hiera function in the manifests. In your own manifests you could use data binding and parametized classes to achieve the same ends.
