Using HCL with Packer

While Packer was initially created to allow users to use JSON to describe their desired image builds, it now also supported HashiCorp Configuration Language 2, which has some additional benefits to JSON, such as breaking up our build into reusable files. In this lab, we'll explore creating a parallel Amazon and Docker image build using HCL building blocks.
