Deploying Serverless Transforms with AWS CodePipelines - amazon-web-services

Question

I have a pipeline set up per this CloudFormation Template.
When I try to deploy a template that is using AWS SAM, I get an error in the pipeline
Action execution failed
CreateStack cannot be used with templates containing Transforms. (Service: AmazonCloudFormation; Status Code: 400; Error Code: ValidationError; Request ID: 167007a4-7672-11e8-8f67-67e79ae9de20)
which is notabily complain about my Action Mode,
Configuration:
ActionMode: CREATE_UPDATE
I can use a Pipeline Code Build stage that uses AWS CLI cloudformation package like this,
version: 0.1
phases:
install:
commands:
- npm install time
- aws cloudformation package --template-file samTemplate.yaml --s3-bucket bucket-name
--output-template-file outputSamTemplate.yaml
artifacts:
type: zip
files:
- samTemplate.yaml
- outputSamTemplate.yaml
But I would rather use something prebuilt. How do I deploy Serverless Transform Cloudformation Templates with CodePipelines? Can I do it without using the AWS CLI to package and deploy the template?

Spinning up a CodeStar Python project gave me the answer. They notably have two Cloudformation actions in their deploy stage that do CHANGE_SET_REPLACE and CHANGE_SET_EXECUTE.
Removing extraneous info from the CF template, you can see the structure of the actions in,
Resources:
...
ProjectPipeline:
Type: 'AWS::CodePipeline::Pipeline'
Properties:
Stages:
-
Name: Deploy
Actions:
- Name: GenerateChangeSet
ActionTypeId:
Provider: CloudFormation
Configuration:
ActionMode: CHANGE_SET_REPLACE
- Name: ExecuteChangeSet
ActionTypeId:
Provider: CloudFormation
Configuration:
ActionMode: CHANGE_SET_EXECUTE
Below is the full template resource for the pipeline. Using the same buildspec.yml as above, their CodePipeline template looks like,
Resources:
...

Type: 'AWS::CodePipeline::Pipeline'
