Vagrantfile

# For AWS, you need the following ENV variables:
# AWS_ACCESS_KEY_ID
# AWS_SECRET_ACCESS_KEY
# AWS_KEYPAIR_NAME (default 'aws-syd')
# SSH_PRIVKEY (default '~/.ssh/aws-syd.pem')
#
# In addition, your AWS should have a "vagrant" security group available. The AWS setup
# is pretty much locked down to ap-southeast-2b atm - if you want a different region,
# you'll need change AWS_REGION and AWS_AMI, and find an appropriate image at
# http://cloud-images.ubuntu.com/locator/ec2/
#
# This was largely cribbed from https://github.com/relateiq/docker_public/blob/master/Vagrantfile
