Terraform - 将输出导出到变量问题

Question

我正在尝试获取在 vpc 模块中创建的 elastic_ip ID，并将其传递给 trasnfer 系列模块，以在面向 Internet 的 VPC 中部署 AWS trasnfer 系列服务器。

所以我正在创建两个弹性 IP，每个子网一个。 （有两个子网）

resource "aws_vpc_endpoint" "aws_trasnfer_server" {
  vpc_id = aws_vpc.shared_services_vpc.id
  service_name = "com.amazonaws.${var.aws_region}.transfer.server"
  subnet_ids = ["${aws_subnet.public_subnet_2a.id}", "${aws_subnet.public_subnet_2b.id}"]
  security_group_ids = ["${aws_default_security_group.default.id}"]
  vpc_endpoint_type = "Interface"
}

locals {
  network_interfaces = aws_vpc_endpoint.aws_trasnfer_server.network_interface_ids
  # private_id = aws_vpc_endpoint.aws_trasnfer_server.network_interface_ids
}

resource "aws_eip" "subnet_eips_one" {
  for_each = local.network_interfaces
  vpc = true
}

上面的代码工作正常，但我无法导出 elastic_ip ID 并传递给 trasnfer 模块。 这是 vpc 模块的 output.tf

output "elastic_ips" {
  value = toset(values(aws_eip.subnet_eips_one[*].id))
  # aws_security_group.example.*.id
} 

运行脚本时出现以下错误

╷
│ Error: Unsupported attribute
│ 
│   on vpc/outputs.tf line 19, in output "elastic_ips":
│   19:   value = toset(values(aws_eip.subnet_eips_one[*].id))
│ 
│ This object does not have an attribute named "id".

我可以看到

的输出

toset(values(aws_eip.subnet_eips_one))

如下和错误。

我尝试了多种选择，但无法准确获取 ID 并将其传递给输出变量。

我错过了什么吗？预先感谢您的帮助。

谢谢。

你的一个

位置不对。另外你真的不需要

toset

。所以应该是：

value = values(aws_eip.subnet_eips_one)[*].id
