Prepping an Opworks instance for an AMI.

gistfile1.txt

Overview instructions:
http://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-custom-ami.html
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/creating-an-ami-instance-store.html
https://dev.infopark.net/e7832b631baf0ce8/creating-an-instance-store-backed-ami-from-a-running-opsworks-instance

Make a very very big powerful box (or else you'll sit there forever waiting for the image to zip up)
SSH into a running blank opsworks box
Do whatever crazy stuff you need to do (install packages, root kits, etc)

Do the stuff at the bottom of here to kill off existing opsworks packages:
http://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-custom-ami.html

Gen dummy X.509 keys:
openssl req -x509 -newkey rsa:2048 -keyout private_key.pem -out cert.pem -days 365 -nodes -batch

Setup ec2-bundle (or AMI tools)
http://docs.aws.amazon.com/AWSEC2/latest/CommandLineReference/set-up-ami-tools.html

Make sure ec2-ami-tools are installed under both users (ubuntu & root)
export EC2_AMITOOL_HOME=/usr/local/ec2/ec2-ami-tools-x.x.x.x
export PATH=$EC2_AMITOOL_HOME/bin:$PATH
ec2-ami-tools-version

Find your account ID under IAM => user => summary
Should look something like:
User ARN: arn:aws:iam::##########:user/Bob

Tweaked ec2-bundle command:
mkdir -p /tmp/bundle && $EC2_AMITOOL_HOME/bin/ec2-bundle-vol -k private_key.pem -c cert.pem -u <acct id> -r x86_64 -e /tmp/cert -d /tmp/bundle --no-filter

# Upload generated bundle
ec2-upload-bundle -b fc-us-amis/rabbitmq-20140606_v2 -m /tmp/bundle/image.manifest.xml -a your_access_key_id -s your_secret_access_key --region us-east-1


Install amazon cli tools on your local dev machine to register the ami
brew install python
pip install amwcli

Register image:
AWS_DEFAULT_REGION=us-east-1 aws ec2 register-image --image-location fc-us-amis/rabbitmq-20140606_v1/image.manifest.xml --name "Ubuntu-12_04-Rabbit-3_3_1-v2"

Fire up the box and pray to some amazon gods that it works. Do not use too large of a box? (m3.medium seems to work).
