Details

The Foundation AMI is just the latest LTS release from Ubuntu with Git and Ansible and installed. Nothing more.

The basis for these AMIs are the Ubuntu 12.04 LTS 'precise' Cloud Images. The images are all 64-bit and EBS backed.

Create your own Foundation AMI

You can easily create your own Foundation AMI by using the scripts provided here, or modifying them to your needs. There is also a CloudFormation Template called foundation-ami-maker.json that does all of the heavy lifting for you. The basic flow is:

1. Bring up an EC2 instance using the CloudFormation script provided

$ aws cloudformation create-stack
--stack-name Foundation-maker
--template-url http://answers4aws.s3.amazonaws.com/foundation-ami-maker.json
--parameters ParameterKey=InstanceType,ParameterValue=t1.micro,ParameterKey=KeyName,ParameterValue=mykey

This script creates an IAM Role with the necessary permissions needed for AMI making.

__NOTE:__ Change _mykey_ to be your KeyPair

1. Poll the CloudFormation stack progress until you see the 3 steps in the output. It will look something like this:

``` bash
$ aws cloudformation describe-stacks
...
         "Outputs": [
             {
                 "Description": "Step 1: SSH to this instance using your KeyPair",
                 "OutputKey": "step001",
                 "OutputValue": "ssh -i mykey.pem ubuntu@ec2-12-12-12-12.compute.amazonaws.com"
             },
             {
                 "Description": "Step 2: Create a Foundation EBS volume",
                 "OutputKey": "step002",
                 "OutputValue": "./foundation-create-volume"
             },
             {
                 "Description": "Step 3: Create your Foundation AMI from the Foundation EBS volume",
                 "OutputKey": "step003",
                 "OutputValue": "./foundation-create-ami"
             }
         ],
         "StackName": "Foundation-maker",
         "StackStatus": "CREATE_COMPLETE",

1. Then just follow the steps: 1) SSH into the instance, 2) Create the EBS Volume, 3) Create the Foundation AMI from the volume.

Between Steps 2 and 3, you can go into the chroot environment and make further customizations to the Foundation AMI. It is highly recommended to script that if you do.

Once you are done, you can delete the CloudFormation stack. The entire process is complete in under 30 minutes.
