Purpose

Provide a method for creating a foundation image suitable for amination that doesn't depend on publicly released AMIs. We're using Ubuntu cloud-images but this procedure should work on anything that you can get an image for.

Setup

Overview

  • We're going to launch an EC2 instance so that we can create and manipulate EC2 volumes and AMIs
  • Install chef-solo and a Chef recipe to get our instance configured to run ec2-api-tools and provide some scripts
  • We'll use the ec2-api-tools to manage our EC2 resources. IAM IAM credentials make this much simpler and tools such as ec2-api-tools already know how to pull the proper credentials from the instance meta-data
  • Create an EBS volume, dd an image to it, umount, snapshot and register an AMI from the snapshot
  • This AMI is now our foundation AMI that we can run aminate on to build a Base AMI
  • The Base AMI will be used later

Prerequisites

  • AWS account
  • IAM profile with proper EC2 credentials (e.g. Power User)

First, we need to be running in EC2 so that we can create Select the Ubuntu Server 12.04.1 LTS AMI
