如何在资源参数上创建if语句？

我有循环在AWS上创建2个EC2。我想在其中唯一的一个上传递user_data参数，因此我的想法是创建IF语句以实现这一目标。类似的内容：

实例EC2

resource "aws_instance" "web" {
  count                       = length(var.vms)
  ami                         = data.aws_ami.ubuntu.id
  instance_type               = var.instance_type
  key_name                    = var.key_name
  get_password_data           = false
  associate_public_ip_address = true
  vpc_security_group_ids      = [var.secgr_id]
  iam_instance_profile        = aws_iam_instance_profile.ec2_instance_profile.name
  user_data = var.vms[count.index] == "some-vm-name" ? "${file(var.file_name)}" : null
  tags = {
    Name = var.vms[count.index]
  }
  lifecycle {
    prevent_destroy = true
  }
}

它实际上选择了我想要的VM，但是我从未执行过通过文件函数执行脚本吗？

这可以做吗？

I have for loop that creates 2 ec2s on aws. I want to pass user_data argument on the only one of them, so my idea is to create if statement to accomplish this.
Something like this:

Instance EC2

resource "aws_instance" "web" {
  count                       = length(var.vms)
  ami                         = data.aws_ami.ubuntu.id
  instance_type               = var.instance_type
  key_name                    = var.key_name
  get_password_data           = false
  associate_public_ip_address = true
  vpc_security_group_ids      = [var.secgr_id]
  iam_instance_profile        = aws_iam_instance_profile.ec2_instance_profile.name
  user_data = var.vms[count.index] == "some-vm-name" ? "${file(var.file_name)}" : null
  tags = {
    Name = var.vms[count.index]
  }
  lifecycle {
    prevent_destroy = true
  }
}

It actually choses VM that i want, but the script is never executed that i pass through file function?

Is this possible to do?
