  bucket = "tf-spot-datafeed"
}

resource "aws_spot_datafeed_subscription" "default" {
  bucket = "${aws_s3_bucket.default.bucket}"
  prefix = "my_subdirectory"
}
```

## Argument Reference
* `bucket` - (Required) The Amazon S3 bucket in which to store the Spot instance data feed.
* `prefix` - (Optional) Path of folder inside bucket to place spot pricing data.

## Import
