Using Packer to Create an AWS AMI
Packer lets us create machine images for a variety of platforms through code. A Packer template requires at least a builder and a communicator to provision an image. In this lab, we'll create an AWS machine image using the `amazon-ebs` builder and `ssh` communicator.
