Jenkinsfile idiosynchrasies with escaping and quotes
node {
echo 'Results included as an inline comment exactly how they are returned as of Jenkins 2.121, with $BUILD_NUMBER = 1'

# Windows AMIs don't have WinRM enabled by default -- this script will enable WinRM
# AND install 7-zip, curl and .NET 4 if its missing.
# Then use the EC2 tools to create a new AMI from the result, and you have a system
# that will execute user-data as a PowerShell script after the instance fires up!
# This has been tested on Windows 2008 SP2 64bits AMIs provided by Amazon
#
# Inject this as user-data of a Windows 2008 AMI, like this (edit the adminPassword to your needs):
#
# <powershell>
# Set-ExecutionPolicy Unrestricted

detect all ephemeral disks on EC2 then stripe together in a raid-0 vol mounted at /mnt
#!/bin/bash
#
# this script will attempt to detect any ephemeral drives on an EC2 node and create a RAID-0 stripe
# mounted at /mnt. It should be run early on the first boot of the system.
#
# Beware, This script is NOT fully idempotent.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Bootstrap Windows EC2 node with WinRM and CloudInit for making your own AMI
# Windows AMIs don't have WinRM enabled by default -- this script will enable WinRM
# AND install the CloudInit.NET service, 7-zip, curl and .NET 4 if its missing.
# Then use the EC2 tools to create a new AMI from the result, and you have a system
# that will execute user-data as a PowerShell script after the instance fires up!
# This has been tested on Windows 2008 R2 Core x64 and Windows 2008 SP2 x86 AMIs provided
# by Amazon
#
# To run the script, open up a PowerShell prompt as admin
