I’m trying to create multiple Github repos and add files to that newly created repos using a JSON file.

# Terraform Locals
locals {
  binding_pairs = toset([
    for pair in setproduct(
      keys(data.github_repository_file.main),
      keys(github_repository.main),
      ) : {
      files = pair[0]
      repos = pair[1]
    }
  ])
}

locals {
  json_files   = fileset("${path.module}/environments/", "*.json")
  json_data    = [for i in local.json_files : jsondecode(file("${path.module}/environments/${i}"))]
  json_content = { for i in local.json_data : i.github_repo_name => i.github_repo_description }
  terraform_data = [for i in local.json_files : file("${path.module}/environments/${i}")]
}

# Terraform Data Sources
data "github_repository_file" "main" {
  for_each = var.github_repo_files

  repository = var.source_repo_name
  branch     = "main"
  file       = each.key
}

# Terraform GitHub Repository
resource "github_repository" "main" {
  for_each = local.json_content

  name        = each.key
  description = each.value
  auto_init   = true
  visibility  = "public"
}

# Terraform GitHub Repository Files
resource "github_repository_file" "main" {
  for_each = { for p in local.binding_pairs : "${p.files}:${p.repos}" => p }

  repository          = github_repository.main[each.value.repos].id
  branch              = "main"
  file                = data.github_repository_file.main[each.value.files].file
  content             = data.github_repository_file.main[each.value.files].content
  overwrite_on_create = true
}

resource "github_repository_file" "tfvars" {
  for_each = github_repository.main

  repository          = github_repository.main[each.value].id
  branch              = "main"
  file                = "terraform.tfvars"
  content             = local.terraform_data[each.key] **<< This part how to do??**
  overwrite_on_create = true
}

I need to create a terraform.tfvars.json and the content should be from the JSON file. For example, there will be a folder called environments and JSON files will be created inside those folders.

Example: environments/dev-env.json

{
  "github_repo_name": "Dev",
  "github_repo_description": "GitHub Repo for Dev Environment",
  "app_name": "devapp",
  "short_app_name": "devapp",
  "environment": "test",
  "location": "west europe",
  "vnet_address_space": "10.3.0.0/16",
  "subnet_address_space": "10.3.1.0/24",
  "app_subnet_address_space": "10.3.2.0/24"
}

So now I need to create the terraform.tfvars.json files dynamically when someone creates new JSON files in environments folder.

How to create **github_repository_file.tfvars** resource?
