How to create a folder in an amazon S3 bucket using terraform

Question

I was able to create a bucket in an amazon S3 using this link.

I used the following code to create a bucket :

resource "aws_s3_bucket" "b" {

    bucket = "my_tf_test_bucket"

    acl    = "private"

}

Now I wanted to create folders inside the bucket, say Folder1.

I found the link for creating an S3 object. But this has a mandatory parameter source. I am not sure what this value have to since my intent is to create a folder inside the S3 bucket.

You can use the following to run terraform on macOS or Linux,

resource "aws_s3_bucket_object" "folder1" {

    bucket = "${aws_s3_bucket.b.id}"

    acl    = "private"

    key    = "Folder1/"

    source = "/dev/null"

}

In Windows, you can use an empty file. Using a folder that is a key prefix in S3, makes life easier to take out objects. Like S3 sync for instance.
