Testing a possible workflow with paker.io and vagrant.

README.md

The intended workflow should be:

0. Build the images

   $ packer build template.json
   

1. Import and start an image.

   $ vagrant up --provider=aws
   $ vagrant up --provider=virtualbox
   $ vagrant up --provider=vmware
   

You can set the default vagrant provider with export VAGRANT_DEFAULT_PROVIDER=vmware.
