Finding Packer-generated AMIs automatically after builds

The basic technique is to have Packer add a tag with a unique value during the build, and use AWS' built-in filtering capabilities to find that specific AMI after the build finishes.

• template.json - Shows the settings that need to be added to your template
• build.sh - Shows how to use the template to do a build and retrieve the AMI information

#!/usr/bin/env knife exec

# A knife exec script to change chef node's name, preserving all the attributes.
#
# Usage: knife exec rename-node.rb old-name new-name
#
# Script retrieves the Node object, changes its 'name' attribute,
# creates new Node object with updated name and rest of attributes
# untouched. Then it deletes old Node and Client objects from
# database, and logs into the server to update it:
