[英]How to resolve the error message when adding SQS redrive policy for deadletter queue created using for_each
I want terraform to associate my SQS Management Event with my DLQ management event and i want the same thing done with SQS Data Event and DLQ Data Event.I am getting error messages when i run apply on my code below.please I need some help.我希望 terraform 将我的 SQS 管理事件与我的 DLQ 管理事件相关联,并且我希望对 SQS 数据事件和 DLQ 数据事件做同样的事情。当我在下面的代码上运行应用程序时,我收到错误消息。请我需要一些帮助。
.tfvars
sqs_queue_names = ["CloudTrail_SQS_Management_Event", "CloudTrail_SQS_Data_Event"]
dead_queue_names = ["CloudTrail_DLQ_Management_Event", "CloudTrail_DLQ_Data_Event"]
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)
}
main.tf
resource "aws_sqs_queue" "CloudTrail_SQS"{
for_each = var.sqs_queue_names
name = each.value
redrive_policy = jsonencode({
deadLetterTargetArn = values(aws_sqs_queue.CloudTrail_SQS_DLQ)[*].arn
maxReceiveCount = var.max_receive_count
})
tags = var.default_tags
}
resource "aws_sqs_queue" "CloudTrail_SQS_DLQ"{
for_each = var.dead_queue_names
name = each.value
tags = var.default_tags
}

The problem here is that you are not associating the dead letter queue with the corresponding SQS queue.这里的问题是您没有将死信队列与相应的 SQS 队列相关联。 values(aws_sqs_queue.CloudTrail_SQS_DLQ)[*].arn
- this essentially passes every dead letter queue ARN for each SQS queue, it does not passes to correct ARN only. values(aws_sqs_queue.CloudTrail_SQS_DLQ)[*].arn
- 这实质上传递了每个 SQS 队列的每个死信队列 ARN,它不会仅传递给正确的 ARN。
In order to overcome this, I suggest creating a module where we can tie together the SQS queue and its DLQ.为了克服这个问题,我建议创建一个模块,我们可以在其中将 SQS 队列及其 DLQ 联系在一起。 We can name for now my_sqs
:我们现在可以命名为my_sqs
:
my_sqs/variables.tf
: my_sqs/variables.tf
:
variable "sqs_queue_name"{
description = "The name of different SQS to be created"
type = string
}
variable "dead_queue_name"{
description = "The name of different Dead Queues to be created"
type = string
}
variable "max_receive_count" {
type = number
}
my_sqs/main.tf
: my_sqs/main.tf
:
resource "aws_sqs_queue" "sqs" {
name = var.sqs_queue_name
redrive_policy = jsonencode({
deadLetterTargetArn = aws_sqs_queue.dlq.arn
maxReceiveCount = var.max_receive_count
})
}
resource "aws_sqs_queue" "dlq" {
name = var.dead_queue_name
}
Now we can use this module like this:现在我们可以像这样使用这个模块:
variables.tf
: variables.tf
:
# Please not, we are tying the SQS and the DQL together here as well.
variable "queue_names" {
default = [
{
sqs_name = "CloudTrail_SQS_Management_Event"
dlq_name = "CloudTrail_DLQ_Management_Event"
},
{
sqs_name = "CloudTrail_SQS_Data_Event"
dlq_name = "CloudTrail_DLQ_Data_Event"
}
]
}
From the main.tf
we call the module we created above:从main.tf
我们调用我们上面创建的模块:
main.tf
: main.tf
:
module "my_sqs" {
source = "./my_sqs"
for_each = {
for sqs, dlq in var.queue_names : sqs => dlq
}
sqs_queue_name = each.value.sqs_name
dead_queue_name = each.value.dlq_name
max_receive_count = 4
}
Please note, this example may work with the latest Terraform versions.请注意,此示例可能适用于最新的 Terraform 版本。 It may not work with an older version which does not support having a for_each
on a module
.它可能不适用于不支持在module
上使用for_each
的旧版本。
