Question

如标题所述，我正在尝试从共享快照创建多个AWS EBS。

我正在使用数据“ aws_ebs_snapshot_ids” 获取快照列表，然后使用 for_each 创建EBS卷。像这样

data "aws_ebs_snapshot_ids" "shared_snapshot_ids" {
  filter {
   name   = "description"
    values = ["snap-test*"]
  }
}

resource "aws_ebs_volume" "shared_snapshot_volume" {
    for_each = toset(data.aws_ebs_snapshot_ids.shared_snapshot_ids.ids)
    snapshot_id = each.value
    availability_zone = "us-west-1b"

现在，我想用快照描述来标记这些卷，但是 data“ aws_ebs_snapshot_ids 并不会返回描述，只是ID列表。因此，我必须使用 data” aws_ebs_snapshot“ 和 for_each 循环以获取描述，并返回快照的映射。

data "aws_ebs_snapshot" "shared_snapshot" {
  for_each = toset(data.aws_ebs_snapshot_ids.shared_snapshot_ids.ids)
  snapshot_ids = ["${each.value}"]
}

output "shared_snapshot" {
  value = data.aws_ebs_snapshot.shared_snapshot
}

"snap-0000000000001" = {
    "data_encryption_key_id" = ""
    "description" = "snap-test-2"
    "encrypted" = false
    "id" = "snap-0000000000001"
    "kms_key_id" = ""
    "most_recent" = false
    "owner_alias" = ""
    "owner_id" = ""
    "snapshot_id" = "snap-0000000000001"
    "snapshot_ids" = [
      "snap-0000000000001",
    ]
    "state" = "completed"
    "tags" = {}
    "volume_id" = ""
    "volume_size" = 100
  }
  "snap-0000000000000" = {
    "data_encryption_key_id" = ""
    "description" = "snap-test-1"
    "encrypted" = false
    "id" = "snap-0000000000000"
    "kms_key_id" = ""
    "most_recent" = false
    "owner_alias" = ""
    "owner_id" = ""
    "snapshot_id" = "snap-0000000000000"
    "snapshot_ids" = [
      "snap-0000000000000",
    ]
    "state" = "completed"
    "tags" = {}
    "volume_id" = "vol-0000000000000"
    "volume_size" = 8
  }
}

我不知道Terraform如何或是否可以做到这一点，但我想它将需要类似

resource "aws_ebs_volume" "shared_snapshot_volume" {
    for_each = toset(data.aws_ebs_snapshot_ids.shared_snapshot_ids.ids)
    snapshot_id = each.value
    availability_zone = "us-west-1b"


    tags = {
      Name    = data.aws_ebs_snapshot.shared_snapshot.[${each.value}].description
    }
}

这是嵌套插值，因此不起作用。请告诉我这对于Terraform是否可以实现，或者我需要使用其他方法。

您可以使用 aws_ebs_snapshot 数据源获取这些快照ID的详细信息：

data "aws_ebs_snapshot" "shared_snapshots" {
  for_each = toset(data.aws_ebs_snapshot_ids.shared_snapshot_ids.ids)
  snapshot_ids = [each.value]
}

然后，您可以使用 snapshot_id 和 description 这样的详细属性来构建EBS卷，如下所示：

resource "aws_ebs_volume" "shared_snapshot_volume" {
  for_each = data.aws_ebs_snapshot.shared_snapshots
    snapshot_id = each.value.snapshot_id
    availability_zone = "us-west-1b"

  tags = {
    Name = each.value.description
  }
}

使用Terraform从共享快照创建多个AWS EBS卷，并用快照描述对其进行标记
