A CLI tool intended to simplify AWS CloudFormation handling.

• cfn templates in yml or json
• build for human interaction and automation (run 'cf sync stacks.yml' triggered by a git push if you dare ;-)
• a source of truth defining cloudformation stacks with their template and parameters
• cross referencing parameters between stacks (use a stack output as parameter for another stack)
• automatic stack dependency resolution including circular dependency detection
• helper features easing the use of cfn functions like Fn::Join, Ref or Fn::GetAtt
• easy user-data definition for https://github.com/zalando-stups/taupage

pip install cfn-sphere

Requirements:

• python >= 2.6
• virtualenv
• pybuilder

Execute:

git clone https://github.com/cfn-sphere/cfn-sphere.git
cd cfn-sphere
virtualenv .venv --python=python2.7
source .venv/bin/activate
pip install pybuilder
pyb install_dependencies
pyb

Create a YAML file containing a region and some stacks in a stacks.yml file f.e.:

region: eu-west-1
stacks:
    test-vpc:
        template-url: vpc.yml
    test-stack:
        template-url: app.yml
        parameters:
            vpcID: "|ref|test-vpc.id"

Write your templates and configure them in your stacks.yml

A simple command synchronizes your definition with reality!

cf sync myapp-test.yml
