coreos-vagrant-gonkulator | Node Clustered CoreOS - Plus Weave

I've forked the CoreOS Vagrant Weave repository and made the requisite changes. So - create an AWS Access Key, setup your AWS environment variables, and vagrant up (for a 3-node virtualbox cluster, or vagrant up --provider=aws for a 3-node cluster on AWS. If you have the Vmware vagrant plugins installed you can do vagrant up --provider=vmware_fusion or vagrant up --provider=vmware_workstation. You should have the VMWare or Virtualbox plugins installed prior to following these instructions. The discovery tokens are updated dynamically at every "vagrant up". If you want to run a cluster larger (much larger?) than 3 - just edit the num_instances variable in config.rb, save and follow the directions below. I've tested it to 20 nodes on AWS.
