This is a very basic Salt master + two Salt minions that connect to it.
Pre-seeded keys for the minions are automatically generated during controller bootup, and accepted by the master during initialistion. Since these are dev keys, obviously don't use them for anything.
Uses ubuntu/trusty as the base box, and the controller and test1/2 boxes on S3 are derived from that.
To pull the boxes without vagrant up, do:
vagrant box add controller https://s3-ap-southeast-2.amazonaws.com/salt-tutorial/controller.box
vagrant box add test1 https://s3-ap-southeast-2.amazonaws.com/salt-tutorial/test1.box
vagrant box add test2 https://s3-ap-southeast-2.amazonaws.com/salt-tutorial/test2.box
