HashiCorp Packer is badass!!!

Here are some examples of how I use it:

1. Create a Debian OVFs on macOS using VMware Fusion


Install packer (free):
brew install packer

Install VMware Fusion Player (free):

OVFTOOL (creates the OVA):

  guest_os_type = "debian10_64Guest"
  disk_size = 4096
  cpus = 1
