Access attributes in a json configuration file


I am currently trying to deploy an infrastructure with Terraform and I have the following need:

My is :

resource "aws_fsx_ontap_storage_virtual_machine" "svm" {
  for_each = { for key, value in jsondecode(file("${path.cwd}/config/svm.json")) : key => value }
  file_system_id =
  name           =

resource "aws_fsx_ontap_volume" "volume" {
  for_each = { for key, value in jsondecode(file("${path.cwd}/config/volumes.json")) : key => value }
  storage_virtual_machine_id = each.value.storage_virtual_machine_id

Both resources are created with for_each (the configurations are in json files).

In resource aws_fsx_ontap_volume, I need to get the attribute id of resource aws_fsx_ontap_storage_virtual_machine.

My volumes.json file is :

    "vol01": {
        "storage_virtual_machine_id": Here I need to put the ids of resource aws_fsx_ontap_storage_virtual_machine (for example aws_fsx_ontap_storage_virtual_machine.svm["svm02"].id)

Is there a simple way to do that ?

Thanks a lot.

At this point you should stop using JSON and write your configuration directly in Terraform’s native language, as this is something you cannot do with this setup.
