Example Puppet ENC

Very simple external node classifier which determines the class by the security group(s) of the node. Also merges the EC2 tags into the parameter section of the classification.

Installation

To run the script you need these gems:

Run

Just replace placeholders in

ACCESS_KEY_ID     = '<YOUR_ACCESS_KEY>'
SECRET_ACCESS_KEY = '<YOUR_SECRET_ACCESS_KEY>'
EC2_ENDPOINT          = 'eu-west-1.ec2.amazonaws.com'

and set the right EC2 API endpoint. A simple

./ec2_enc ip-10-10-10-10.eu-west-1.compute.internal 

will do

Acknowledgment

The implementation was heavily inspired by a blog post on the Gowalla engineering blog by Kevin Lord.

Nice work, helped a lot.
