是否可以输出所有在Terraform循环中创建的EC2实例?

resource "aws_instance" "dev-cluster" {
  ami                  = "${lookup(var.amis, var.region)}"
  instance_type        = "${var.instance_type}"
  count                = 13
  subnet_id            = "${var.global-private-subnet-1a-id}"
}

有没有办法在outputs.tf中以某种方式输出所有这些实例ID?

我试过了,但是输出是空的

output "aws_ec2_instance_ids" {
  value = "${aws_instance.dev-cluster.*.id}"
}
