  https://www.packer.io/[Packer] is an open-source infrastructure definition tool used 
  to create machine images for a variety of dynamic infrastructure platforms. It includes  
  builders for many environments, such as:
  
  * VirtualBox
  * Amazon EC2
  * VMware vSphere
  * Google Compute Engine
  * Docker
  
  The build process is driven by a template: a configuration file (in JSON format) that defines 
  how a machine image is created and automatically provisioned.
  
  To install Packer, simply download the appropriate https://www.packer.io/downloads.html[binary package] 
  for your environment and unpack the archive into a suitable directory; then set the following
