説明

Describe the bug

When using CDK pipelines to deploy preview environments it is very important that a CDK destroy actually cleans up all of the resources.

This bucket https://github.com/aws/aws-cdk/blob/fdb4ddb446d3c17088d81104191d6688ca4ce721/packages/aws-cdk-lib/aws-codepipeline/lib/private/cross-region-support-stack.ts#L79C10-L79C27

Does not have a resource policy or autodeleteobjects set.

It would be nice if the CDK was better written to allow for stack destroys and recreates.

Expected Behavior

When running cdk destroy you are able to set resource policies so that if you are using the cdk to deploy preview environments you have clean teardowns.

Current Behavior

the mentioned bucket is orphaned and if you try to redeploy your app it fails

Reproduction Steps

create a cross region cdk pipeline

Possible Solution

allow us to define the resource policy

調査方針
Investigate the cross region support stack in packages/aws cdk lib/aws codepipeline/lib/private/cross region support stack.ts, specifically the S3 bucket creation at line ~79. Understand how CDK handles stack destruction and what properties (like autoDeleteObjects or resource policy) are missing. Look for prior PRs or comments that address similar issues.
