Return Transfer ID

[Spritekin]

Describe the Feature

The transfer server ID is not being returned and there is no clear direct way to identify the server. Return the server ID.

Expected Behavior

I understand the ID returned in outputs is not the transfer server ID, so a new output variable is required:

output "transfer_server_id" {
  description = "The Transfer Server ID"
  value       = module.this.enabled ? join("", aws_transfer_server.default.*.id) : null
}

or alternatively return the whole object

output "transfer_server" {
  description = "The Transfer Server"
  value       = module.this.enabled ? aws_transfer_server.default : null
}

Use Case

I would like to reference the transfer server downstream so I can add some features not managed by this module (i.e. an unrestricted user or multiple users on the same folder).

Describe Ideal Solution

data "aws_transfer_server" "sftp" {
  server_id = module.sftp.transfer_server_id
}

Or if solution 2 is used, then I can just get it as

data "aws_transfer_server" "example" {
  server_id = module.sftp.transfer_server.id
}

Alternatives Considered

I was looking to tag the transfer server so I can lookup the server by tags but this functionality is not available in the transfer_server data object.

Additional Context

Add any other context or screenshots about the feature request here.

Update, I have noticed the endpoint contains the server id as the first item in the URL. I'm changing to fetch the first word in the endpoint for now.

module "sftp" {
  source          = "cloudposse/transfer-sftp/aws"
  version         = "0.6.0"
  ... all other config
}

data "aws_transfer_server" "sftp" {  
  server_id = split(".", module.sftp.transfer_endpoint)[0]
  depends_on = [module.sftp]
}
