Customizations for AWS Control Tower Solution - CFN SAM Support

Question

Hi - We are using CfCT, which is great. We currently have cloudformation templates mapped to specific Organizational Units and it works like a charm. I now have a AWS SAM Template that I would like to deploy but I could find 0 documentation about it. At the solution repository, I can see that are features enabled to support SAM[1], but no guidance on how to do it.

Could you please share more information on how to deploy a AWS SAM Template through CfCT?

Answer

You should be able to simply take the CloudFormation route of deploying SAM:

```
Transform: AWS::Serverless-2016-10-31
Resources:
  SomeServerlessFunc:
    Type: AWS::Serverless::Function
    Properties:
      Handler: index.handler
      Runtime: nodejs12.x
      CodeUri: 's3://bucketo/source.zip'
```

(Same goes for `AWS::Serverless::Application` et al)

Answer

As mentioned by Raphael you can describe the SAM in CFT then update your manifest file on to where to apply the template. Depending on your manifest file version you can apply at -Root -OU  or -Account levels.
