How to add multiple email address to a SNS topic via cloudformation?

Question

is it possible to add more than one email address to a SNS topic subscription via cloudformation

SNSTopic:
   Type: AWS::SNS::Topic
   Properties:
    Subscription:
    - protocol:email
      Endpoint: abc@gmail.com

Answer 1

There are no loops in CFN. So you have to explicitly list all your email addresses:

SNSTopic:
   Type: AWS::SNS::Topic
   Properties:
    Subscription:
    - protocol:email
      Endpoint: abc@gmail.com
    - protocol:email
      Endpoint: second@gmail.com
    - protocol:email
      Endpoint: third@gmail.com

If you want to do it dynamically, you have to create your own macro or custom resource.
