Verify Installation

JSON/YAML Templates

Atom-cfn-lint will work with JSON and YAML files but the goal is to only scan CloudFormation templates. As a result we look for AWSTemplateFormatVersion being defined in the file. CloudFormation only requires Resources to be defined but this is too generic for assuming that the file is a CloudFormation template.

Example

You can use the following example to verify that the installation was successful:

AWSTemplateFormatVersion: "2010-09-09"
Resources:
  # Unsupported Type "AWS::EC2::Instance1" 
  MyEC2Instance1:
    Type: "AWS::EC2::Instance1"

Result (Type is marked as an error):

Result

See Templates for more examples.
