Answer

@ST Team, you can use the `ExpiredObjectDeleteMarker` in the rule section of a lifecycle policy in CloudFormation - more info at https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-s3-bucket-lifecycleconfig-rule.html#cfn-s3-bucket-rule-expiredobjectdeletemarker

Answer

Hi,

You should set these values:
* AWS::S3::Bucket NoncurrentVersionExpiration: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-s3-bucket-lifecycleconfig-rule-noncurrentversionexpiration.html
* ExpiredObjectDeleteMarker: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-s3-bucket-lifecycleconfig-rule.html#cfn-s3-bucket-rule-expiredobjectdeletemarker

```
Resources:
  S3Bucket:
    Type: AWS::S3::Bucket
    Properties:
      LifecycleConfiguration:
        Rules:
          - Id: MyRule
            Status: Enabled
            NoncurrentVersionExpiration:
              NoncurrentDays: 30
            ExpiredObjectDeleteMarker: true
```
