User data script to spin up a Ubuntu-based Jenkins server on the EC2 clouds

jenkins-user-script.sh

#!/bin/bash
#
# User data script which sets up Jenkins on Ubuntu using Puppet
#
# For example:
#
#     $ ec2-run-instances ami-5a19976a -t m1.small --region us-west-2 \
#           --key ec2-keypair --user-data-file Desktop/jenkins-user-script.sh
#     $ ssh -i ~/.ssh/ec2-keypair-us-west-2 \
#           ubuntu@ec2-xxx-xxx-xxx-xxx.us-west-2.compute.amazonaws.com
#
# This requires ports 22 and 8080 to be open
#
#     $ ec2-authorize --region us-west-2 default -p 22
#     $ ec2-authorize --region us-west-2 default -p 8080
#
# Cut your carbon, use us-west-2!
