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
- allow stack parameter values updates in command line interface

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
To update parameters of a stack without having to modify the templates, simply use the --parameter or -p flag.
cf sync --parameter "test-stack.vpcID=vpc-123" --parameter "test-stack.subnetID=subnet-234" myapp-test.yml
