Bootstrap chef onto a new system. Based on Jo Liss's bootstrap http://www.opinionatedprogrammer.com/2011/06/chef-solo-tutorial-managing-a-single-server-with-chef/. Run sh depoly.sh user@ipaddress_or_host to deploy

deploy.sh

#!/bin/bash

# Usage: ./deploy.sh [host]
# e.g. sh deploy user@123.212.11.14

host="$1"

# The host key might change when we instantiate a new VM, so
# we remove (-R) the old host key from known_hosts
ssh-keygen -R "${host#*@}" 2> /dev/null
