Terraform：特定于 ubuntu 20.08 LTS AWS 的 AMI 列表

Question

问题：我正在使用 terraform 获取特定操作系统的 AMI 列表 - ubuntu 20.08

我检查了不同的示例链接

当我使用脚本时，这不会给我 AMI 列表

脚本

data "aws_ami" "ubuntu" {
    most_recent = true

    filter {
        name   = "name"
        values = ["ubuntu/images/hvm-ssd/ubuntu-xenial-20.08-amd64-server-*"]
    }
    
    filter {
        name = "virtualization - type"
        values = ["hvm"]
    }

    owners = ["AWS"]
}

我也提到了以下链接

Terraform 中如何使用数据源？

输出：

[ec2-user@ip-172-31-84-148 ~]$ terraform plan
provider.aws.region
  The region where AWS operations will take place. Examples
  are us-east-1, us-west-2, etc.

  Enter a value: us-east-1

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_ami.std_ami: Refreshing state...

------------------------------------------------------------------------

No changes. Infrastructure is up-to-date.

This means that Terraform did not detect any differences between your configuration and real physical resources that exist. As a result, no actions need to be performed.

我不知道我哪里出错了我检查了很多链接，我在下面列出了一些链接。

您的数据应该是：

data "aws_ami" "ubuntu" {

    most_recent = true

    filter {
        name   = "name"
        values = ["ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-*"]
    }

    filter {
        name = "virtualization-type"
        values = ["hvm"]
    }

    owners = ["099720109477"]
}

output "test" {
  value = data.aws_ami.ubuntu
}

Ubuntu 的所有者不是 AWS，而镜像是ubuntu-focal-20.04-amd64-server-，不是ubuntu-xenial-20.08-amd64-server-。

上述结果为 ( us-east-1)：
