Find S3 Bucket Owner

Question

If there is a bucket that I have read/write access on from my AWS account, is there any way to get the CanonicalUser id of the owner?

Reading the ACL Policy seems to be impossible unless you are the owner : /.

Solution

Use get-bucket-acl, if you have read permission of the bucket. It would give output like this

{
    "Owner": {
        "DisplayName": "my-username",
        "ID": "7009a8971cd538e11f6b6606438875e7c86c5b672f46db45460ddcd087d36c32"
    },
    "Grants": [
        {
            "Grantee": {
                "DisplayName": "my-username",
                "ID": "7009a8971cd538e11f6b6606438875e7c86c5b672f46db45460ddcd087d36c32"
            },
            "Permission": "FULL_CONTROL"
        }
    ]
}

object owner is not bucket owner

@homm Yeah, but from the question I understood the OP wanted to know the bucket owner...

Seem like a error in documentation. ListBucketResult.Contents is objects in bucket, so ListBucketResult.Contents.Owner is object's owner.
