aws-c2a

AWS CDK Change Analyzer (C2A)

The AWS C2A Toolkit provides the aws-c2a command-line interface that can be used directly with the cloud assembly of a AWS CDK application. aws-c2a analyzes two CloudFormation templates, extracts their differences and produces a report of changes, customizable with a rules language.

Commands

aws-c2a diff

Computes the difference between the current cloud assembly state and the currently deployed application. aws-c2a diff outputs the report to a file and returns 0 if no differences are found.

aws-c2a diff --app='path/to/assembly/' --rules-path='path/to/rules.json' --out='path/to/output.json'

aws-c2a html

Generate an html file that aggregates the output of aws-c2a diff.

aws-c2a html --report='path/to/change-report.json' --out='path/to/index.html'

aws-c2a vis

Generate an html file that visualizes the diff tree of your app.

Currently, only evaluates the first object in the template tree and does not support nested stacks

aws-c2a vis --app='path/to/assembly/' --out='path/to/index.html'
