Creating Dev and Production Images with Packer in Parallel

One of the primary benefits of using Packer to build your images is it can create multiple images in parallel, allowing you to use the same baseline to provision things such as both development and production images. In this lab, we'll take a Packer template set to create a web instance and add the ability to provision a Docker image.
