When you create a pipeline from CodePipeline during the step-by-step it creates a CloudWatch Event rule for a given branch and repo

like this:

{

"source": [

"aws.codecommit"

],

"detail-type": [

"CodeCommit Repository State Change"

],

"resources": [

"arn:aws:codecommit:us-east-1:xxxxx:repo-name"

],

"detail": {

"event": [

"referenceCreated",

"referenceUpdated"

],

"referenceType": [

"branch"

],

"referenceName": [

"master"

]

}

}

Comprehensive and Detailed Explanation From Exact Extract:

For gradual traffic shifting in Lambda deployments, AWS Lambda aliases support the RoutingConfig property, which specifies the percentage of traffic routed to different versions of the Lambda function. This enables weighted traffic shifting between versions as part of deployment strategies.

The AWS::Lambda::Alias resource’s RoutingConfig can specify multiple versions with weights, enabling canary or linear deployment strategies without needing CodeDeploy resources explicitly.

AWS CodeDeploy resources like DeploymentConfig and DeploymentGroup are used primarily for blue/green deployments and managing deployment strategies outside Lambda aliases.

Lambda versions themselves do not have a VersionWeight property; instead, weighted routing is managed via aliases.

Running unit tests in the build phase and aborting on failure (OnFailure=ABORT) prevents deployment if tests fail.

AWS CDK assertions module provides programmatic unit tests against synthesized templates (Option D).

The --rollback flag relates to CloudFormation stack rollback, not test gating.

The --require-approval flag controls manual approvals, not test outcomes.

cdk diff checks for changes but is not a unit test and may not catch logical errors.
