Provisioning a Packer Image with Masterless Salt
Packer lets us create machine images for a variety of platforms through code. Part of the image creation process involves provisioning the machine, which can be done with a variety of provisioners, including Salt. All Salt provisioning is done via the `salt-call` command, with Salt run masterless. In this lab, we'll use Salt and Packer to ensure our website has a working image by using a custom Salt minion config.
