如何以有序的格式将使用for_each创建的每个SQS和DLQ相互关联

Question

Terragrunt.hcl
terraform {
source = "../..//infrastructure/module"
}

include {
path = find_in_parent_folders()
}
inputs = {
sqs_queue_names                  = ["CloudTrail_SQS_Management_Event", "CloudTrail_SQS_Data_Event"]
dead_queue_names                 = ["CloudTrail_DLQ_Management_Event", "CloudTrail_DLQ_Data_Event"]
}

我从terragrunt配置中调用的模块

Variable.tf
variable "sqs_queue_names"{
description = "The name of different SQS to be created"
type        = set(string)
}
variable "dead_queue_names"{
description = "The name of different Dead Queues to be created"
type        = set(string)
}

resource "aws_sqs_queue" "CloudTrail_SQS"{
for_each                   = {for idx, val in var.sqs_queue_names: idx => val}
name                       = each.value
redrive_policy = jsonencode({
deadLetterTargetArn    = values(aws_sqs_queue.CloudTrail_SQS_DLQ)[each.key].arn
maxReceiveCount        = var.max_receive_count
})
tags = var.default_tags

}
resource "aws_sqs_queue" "CloudTrail_SQS_DLQ"{
for_each                   = toset(var.dead_queue_names)
name                       = each.value

tags = var.default_tags
}

更新后的代码。我从terragrunt配置中调用模块来创建2个SQS和2个DeadLetterQueue。我想要terraform创建"cloudtrail_sqs_management_event";并将其与"cloudtrail_dlq_management_event"关联，同时创建"cloudtrail_sqs_data_event"。并将其关联"CloudTrail_DLQ_Data_Event">

请更改:

type        = set(string)

到

type        = list(string)

原因是set不能被索引访问。
