Build a Custom Amazon EC2 Machine Image (CentOS 6.2) (24-June-2012)
There is no shortage when it comes to finding an available Amazon Elastic Compute Cloud (EC2) Machine Image (AMI). Often times, however, finding an image from the community AMIs that meets your particular needs can be a challenge. In many cases the image is bloated, provides too much customization, performs poorly, or lacks any type of reasonable documentation. Not to mention the inherent security concerns associated with some 3rd party AMIs. In the article described at the end of the newsletter, I will demonstrate how to create your own instance store-backed (a.k.a. S3-backed) and EBS-backed Amazon EC2 image of CentOS 6.2 (64-bit) with its own kernel. Creating your own AMI allows you to make the most of Amazon EC2 and provides better control over performance, security, and reproducibility. Your AMIs become the basic unit of deployment which allow you to rapidly boot new custom instances as you need them. There are two methods to prepare your own custom Amazon EC2 instances for Linux/UNIX systems: 1.) From an Existing AMI Involves launching an existing public AMI and modifying it according to your requirements. 2.) Create a New AMI from Scratch on Your Own Machine (loopback method) Involves building a fresh installation either on a stand-alone machine or on an empty file system mounted by loopback. Although preparing a new AMI from an existing one is often the easiest method, this guide will document the procedures to create a new AMI from scratch using a fresh OS install of CentOS 6.2 (64-bit) on an empty file system mounted by loopback.
