Nested Stack in CloudFormation

Question

I recently got access to one of the Dev Account of AWS.

I was going through CloudFormation templates and did not understand the behavior of some templates.

I clicked on one of the CloudFormation stack names and inside it shows me some 5 nested stacks. When I checked the template of this stack I could not find any code which justifies that it uses nested stacks. So I could not find any keywords like below in the template:

    "Type": "AWS::CloudFormation::Stack

               OR

    Transform" : {
   "Name" : "AWS::Include",

Here I am confused if the main stack does not have any of the above functions then how does it show 5 nested stacks inside it?

Answer 1

There might be a macro adding the resources dynamically. Try looking for:

Transform:

You can also check out the processed template from the Console. Go to the Template for the root stack and toggle the View processed template button in that section.
