Create multiple resources using same terragrunt.hcl file

[mjohn7421]

Below is the input section for one of my terragrunt.hcl file. This one will create 1 vpc endpoint resource, suppose if i have 5 vpc endpoints to create, should we create 5 terragrunt.hcl file to provide inputs for those 5? can we achieve this via single terragrunt.hcl file by providing multiple inputs?

inputs = { eks_cluster_name = env_vars.cluster_name tags = local.tags vpc_id = local.vpc_outputs.vpc_id.value route_table_ids = var.vpc_outputs.private_route_table_ids. name = "vault" endpoint_type = "Interface" interface_endpoint_service_name = vault_endpoint_service_name subnet_ids = try(local.vpc_outputs.private_subnets.value, ["subnet-123456", "subnet-123456", "subnet-123456"]) create_vpc_endpoint = include.env_vars.locals.create_cog_infra }

Hi,
I think bhis can be achieved by changing Terraform code to support list of inputs...

# terraform
variable "endpoints" {
  type = list(object({
    name                            = string
    endpoint_type                   = string
    interface_endpoint_service_name = string
    subnet_ids                      = optional(list(string), [])
  }))
}

...
resource "aws_vpc_endpoint" "this" {
  for_each = { for idx, endpoint in var.endpoints : idx => endpoint }

  vpc_id              = var.vpc_id
  service_name        = each.value.interface_endpoint_service_name
  vpc_endpoint_type   = each.value.endpoint_type
  subnet_ids          = each.value.subnet_ids
  private_dns_enabled = true

  tags = merge(
    var.tags,
    {
      Name = each.value.name
    }
  )
}


# terraform.hcl

inputs = {
...
  endpoints = [
    {
      name                            = "vault"
      endpoint_type                   = "Interface"
      interface_endpoint_service_name = vault_endpoint_service_name
      subnet_ids                      = ["subnet-123456", "subnet-123456", "subnet-123456"]
    },
    {
      name                            = "s3"
      endpoint_type                   = "Gateway"
      interface_endpoint_service_name = s3_endpoint_service_name
      subnet_ids                      = ["subnet-234567", "subnet-234567", "subnet-234567"]
    }
...
  ]
}

The solution provided by @denis256 works great in the context of a single piece of state, and for multiple pieces of state each of which would have their own terragrunt.hcl file, there's the alternative of the proposal in #3313. Stacks would not be a trivial enhancement, however.

Closing this issue, as the initially reported enhancement is addressed by the comment above.
