Terraform输出配置

Question

我有地形问题。我想像显示可用性区域一样显示输出。我有两个EC2实例和一个数据源，可以通过filter参数获取其中一个实例的可用性区域之类的详细信息，并将结果转发到输出，但我得到了一个错误。

Main.tf

resource "aws_instance" "ec2-1"{
  ami="ami-0a54aef4ef3b5f881"
  instance_type="t2.micro"
  tags={
    Name="Instance-1"
  }
  depends_on=[aws_instance.ec2-2]
}

resource "aws_instance" "ec2-2"{
  ami="ami-026dea5602e368e96"
  instance_type="t2.micro"
  tags={
    Name="Instance-2"
  }
}

data "aws_instance" "instancesearch"{
  filter {
    name="tag:Name"
    values=["Instance-2"]
  }
}

output "instanceid"{
  value = data.aws_instance.instancesearch.availability_zone
}

terraform plan result:


Refreshing Terraform state in-memory prior to plan...

The refreshed state will be used to calculate this plan, but will not be

persisted to local or remote state storage.


data.aws_instance.instancesearch: Refreshing state...

您不需要使用单独的数据源来获取可用性区域。您可以将其作为资源本身的属性。试试这个：

output "availability_zone" {
  value = aws_instance.ec2-2.availability_zone
}
