rulegen

Takes a JSON- or YAML-formatted Amazon CloudFormation template file and autogenerates a set of Amazon CloudFormation Guard rules that match the properties of the template resources. This command is a useful way to get started with rule writing or to create ready-to-use rules from known good templates.

Syntax

cfn-guard rulegen
--output <value>  
--template <value>

Parameters

-h, --help

Prints help information.

-V, --version

Prints version information.

Options

-o, --output

Writes the generated rules to an output file. Given the potential for hundreds or even thousands of rules to emerge, we recommend using this option.

-t, --template

Provides the path to a CloudFormation template file in JSON or YAML format.

Examples

cfn-guard rulegen --output rules.guard --template template.json
