Get output parameter for all AWS Resources in Cloudformation Template

Question

I have an AWS Cloudformation template for creating N number of SQS Queues. The template doesn't contain any other type of resource.

Each SQS queue format looks like:

"logical-name-of-queue": {
  "Type": "AWS::SQS::Queue",
  "Properties": {
    "QueueName": "queue-name",
    "DelaySeconds": "0",
    "MaximumMessageSize": "262144",
    "MessageRetentionPeriod": "345600",
    "ReceiveMessageWaitTimeSeconds": "20",
    "VisibilityTimeout": "300"
  }
}

The template should output the "QueueName" of all the Queues. I can include each queue's name in the output like:

"Outputs" : {
    "name-of-queue-" : {
      "Value" : { "Fn::GetAtt" : [ "logical-name-of-queue", "QueueName" ]}
    }
}

But, as N can be large, is there any way to specify the output block is such a way that there is no need to write such output block for each queue?

No. As of today cloudformation doesn't support any kind of for loops

What you can do is to create a JSON some place else (python, ruby, java...). And then load result to CloudFormation API.

Here is a very handy library written in python: troposphere
