Publishing Outputs

CloudFormation stack outputs can be used to advertise information about a service.

Sparta provides different publishing output decorators depending on the type of CloudFormation resource output:

Publishing Resource Ref Values

For example, to publish the dynamically lambda resource name for a given AWS Lambda function, use PublishRefOutputDecorator such as:


lambdaFunctionName := "Hello World"
lambdaFn := sparta.HandleAWSLambda(lambdaFunctionName,
  helloWorld,
  sparta.IAMRoleDefinition{})

lambdaFn.Decorators = append(lambdaFn.Decorators,
  spartaDecorators.PublishRefOutputDecorator(fmt.Sprintf("%s FunctionName", lambdaFunctionName),
    fmt.Sprintf("%s Lambda ARN", lambdaFunctionName)))
}

Publishing Resource Att Values

For example, to publish the dynamically determined ARN for a given AWS Lambda function, use PublishAttOutputDecorator such as:

lambdaFunctionName := "Hello World"
lambdaFn := sparta.HandleAWSLambda(lambdaFunctionName,
  helloWorld,
  sparta.IAMRoleDefinition{})

lambdaFn.Decorators = append(lambdaFn.Decorators,
  spartaDecorators.PublishAttOutputDecorator(fmt.Sprintf("%s FunctionARN", lambdaFunctionName),
    fmt.Sprintf("%s Lambda ARN", lambdaFunctionName), "Arn"))
}
