YAML Definition Example

This example demonstrates a simple approach to definining an infrastructure stack in the YAML data format, and then using Hiera to create the Puppet resources.


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

                        | +--------------------------+ |
                        | |                          | |
 create-resources-group | | create-resources-example | |
                        | |                          | |
                        | +--------------------------+ |

Feel free to change the details in the YAML file to describe additional instances or security groups.


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 create-resources-example region=us-west-1 ensure=absent
puppet resource ec2_securitygroup create-resources-group region=us-west-1 ensure=absent


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

You can’t perform that action at this time.
