Roark

Howard Roark, master architect and builder of AMIs.

Overview

Roark was built to solve the challenge of automating AMI builds across multiple AWS accounts and regions.

• Roark builds AMIs from an Instance created by a Cloud Formation Stack.
• Roark expects to be provided with a Cloud Formation Template that can be used to create this stack.
• This template should create an Instance that is fully configured at bootstrap (via userdata, CloudInit, etc).
• The stack must provide the ID of the Instance to be converted to an AMI (IE. i-1234abcd) as a Cloud Formation Output named InstanceId.
• Once the stack is created, Roark will read the Instance ID from the Cloud Formation Output, stop the Instance, convert it into an AMI and destroy the stack.

Installation

Add this line to your application's Gemfile:

gem 'roark'

And then execute:

$ bundle

Or install it yourself as:

$ gem install roark

Usage

CLI

Once you have a working templated, set your AWS Access and Secret Keys for the target account:

export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=yyy

Create AMI

roark create -n NAME_OF_AMI
             -r AWS_REGION \
             -c PATH_TO_CLOUD_FORMATION_TEMPLATE \
             -p 'Parameter1=value1' \
             -p 'Parameter2=value2' \
             -a '123456789012' \
             -a '123456789013' \
             -t 'AMITag1=val1' \
             -t 'AMITag2=val2'

Destroy AMI

roark destroy -i AMI_ID -r AWS_REGION

Example

The Cloud Formation Template example.json in the /examples directory will create an AMI based off of the public Amazon Linux AMI.

It will write the file hello_world.txt as part of bootstraping via userdata.

To create an AMI using this template, set your AWS Access Key and Secret Key:

export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=yyy

Download the template:

wget https://raw.github.com/intuit/roark/master/examples/example.json

Create an AMI:

roark create -n roark-example-ami -c example.json
