Standalone usage

You might want to use this module without embedding it as a nested stack because you want to share the VPC stack with many other CloudFormation stacks.

npm i @cfn-modules/vpc
aws cloudformation package --template-file ./node_modules/@cfn-modules/vpc/module.yml --s3-bucket $BucketName --output-template-file packaged.yml
aws cloudformation deploy --template-file packaged.yml --stack-name vpc --capabilities CAPABILITY_IAM

Once the stack is created, you can use the stack name (in this case vpc) as the value for the VpcModule parameter in other cfn-modules. If this template has been embedded in a parent template where the default have been overridden, it is important to re-export the outputs of the stack so they can be used in oher stand-alone stacks:

StackName:
    Value: !GetAtt Vpc.Outputs.StackName
    Export:
      Name: !Sub '${AWS::StackName}'

This will mean you can refer to the VpcModule in other configurations.
