How does S3 deployment bucket metadata work?

[pslootweg]

I have a deployment source that has a mix of content including some sub-folders etc.
The https://docs.aws.amazon.com/cdk/api/latest/docs/aws-s3-deployment-readme.html shows a basic example for applying different cache control headers by file extension, but I can't get this to work with sub-folders.
Using 'exclude' is not very targetted, and all of the content seems to receive the last cache control headers applied to anything.

The documentation seems to apply to a totally flat folder structure only?

We use the aws s3 cp command for this. You can view more about this on the CLI docs or on S3's documentation https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingMetadata.html#UserMetadata
