Thank you. Is there a way to make it possible to provide an index of the files stored in a given path in a s3 bucket? using Nginx?

One possibility is to mount the bucket as s3fs and indexing the folders using Nginx, but is is possible to do that without s3fs?

Does this impact CORS. Is there any additional config required in S3/nginx if in S3, AllowedOrgin is set to '*' .

No, I don't think so. nginx would forward the necessary headers if they're set by S3.

I'm assuming this is running on an instance with a S3 bucket policy role, correct? Or the bucket is set to public?

In this case the bucket needs to be public. I'm sure there's a way to authenticate your request to S3 and make it private. I haven't done that myself so far though.
