Outputs

You can use the template Output section to declare information to be passed back to the template user. The outputs are returned by the cfn-describe-stacks command.

You can use literal values or AWS CloudFormation functions to declare output information.

The information in the Outputs section is returned only by cfn-describe-stacks for an existing stack. When the stack fails to create, or when you delete a stack, the values declared in the Output section are not returned.

In the following example, the output named URL returns the literal value http://aws.amazon.com/cloudformation.

"Outputs" : {
    "URL" : {
        "Value" : "http://aws.amazon.com/cloudformation"
    }
}

Most of the sample templates declare an Outputs section (see Example Templates). Also, for technical details about the format of outputs, see Outputs Declaration.
