## Properties

- `alarms`: [IAlarmRef](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_cloudwatch.IAlarmRef.html)[] = [] — The CloudWatch alarms associated with this Deployment Group.

  CodeDeploy will stop (and optionally roll back)
  a deployment if during it any of the alarms trigger.

  Alarms can also be added after the Deployment Group is created using the `#addAlarm` method.

- `alias`: [Alias](/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.Alias.html) (required) — Lambda Alias to shift traffic. Updating the version of the alias will trigger a CodeDeploy deployment.
