Overview

StackResourceCollection

This collection represents the resources for a single Stack. You can enumerate resources, or request a specific resource by its logical resource id.

Other Ways to Get Resource Details

If you want to get a StackResource by its physical resource id, then you should use #stack_resource.

You can also take a look at AWS::CloudFormation::Stack#resource_summaries for light-weight hashes of stack resource details.

Examples:

Enumerating stack resources


# enumerating all resources for a stack
stack.resources.each do |resource|
  puts resource.resource_type ` " " ` resource.physical_resource_id
end

Getting a stack resource by its logical resource id


resource = stack.resources['web']
