Use Terraform to create folder and subfolder in s3 bucket - amazon-s3

Question

How can I create folder and subfolder in S3 bucket using Terraform?
This is how my current code look like.
resource "aws_s3_bucket_object" "Fruits" {
bucket = "${aws_s3_bucket.s3_bucket_name.id}"
key = "${var.folder_fruits}/"
content_type = "application/x-directory"
}
variable "folder_fruits" {
type = string
}
I would need a folder structure like fruits/apples

Answer 1

Folders in S3 are simply objects that end with a / character. You should be able to create the fruits/apples/ folder with the following Terraform code:
variable "folder_fruits" {
type = string
}
resource "aws_s3_bucket_object" "fruits" {
bucket = "${aws_s3_bucket.s3_bucket_name.id}"
key = "${var.folder_fruits}/"
content_type = "application/x-directory"
}
resource "aws_s3_bucket_object" "apples" {
bucket = "${aws_s3_bucket.s3_bucket_name.id}"
key = "${var.folder_fruits}/apples/"
content_type = "application/x-directory"
}
It is likely that this would also work without the fruits folder.

You can create a null object with a prefix that ends with '/'. All objects in a bucket are at the same hierarchy level but AWS displays it like folders using '/' as the separator.
resource "aws_s3_bucket_object" "fruits" {
bucket = "your-bucket"
key = "fruits/"
source = "/dev/null"
resource "aws_s3_bucket_object" "apples" {
bucket = "your-bucket"
key = "fruits/apples/"
source = "/dev/null"
}
It creates the following folder like structure:
s3://your-bucket/fruits/
s3://your-bucket/fruits/apples/
