Question

我有一个由多个aws_sqs_queue资源组成的terraform计划，其中更多的资源共享相同的配置。在删除任何重复配置并使用变量之前，我想运行terraform plan以查看它是否有效。但是我一直在努力 -

module root: 1 error(s) occurred:

* data.template_file.ep_match_result_queues: resource repeated multiple times

我试过谷歌搜索，但没有太多可用的信息。任何帮助都感激不尽。我的计划看起来像这样:(忽略额外的大括号，拼写错误，因为这只是一个骨架，可以让您大致了解该计划是如何构建的）：

data "template_file" "ep_match_result_queues" {
  template = "${var.namespace}-sm-ep"
}

resource "aws_sns_topic" "sns_topic_name" {
  name            = "ep_sm_match_result_topic${var.environment}"
  display_name    = ""
  policy          = <<POLICY
{
 #policy
}


resource "aws_sqs_queue" "queue1" {
 #config
}

resource "aws_sqs_queue" "queue2" {
 #config

    redrive_policy             = <<POLICY
{
 #policy
}
POLICY
}

resource "aws_sqs_queue" "queue3" {
#config
}

resource "aws_sqs_queue" "queue4" {
 #config

    redrive_policy             = <<POLICY
{
 #policy
}
POLICY
}

resource "aws_sqs_queue" "queue5" {
 #config
}

resource "aws_sqs_queue" "queue6" {
  #config

    redrive_policy             = <<POLICY
{
 #policy
}
POLICY
}

resource "aws_sqs_queue" "queue7" {
 #config
}

resource "aws_sqs_queue" "queue8" {
  #config

    redrive_policy             = <<POLICY
{
 #policy
}
POLICY
}

resource "aws_sqs_queue_policy" "queue_policy" {
  queue_url = [ ... ]
  policy    = "${data.aws_iam_policy_document.match_result_queues_policy.json}"
}

data "aws_iam_policy_document" "match_result_queues_policy" {
 #policy
}

Answer 1

我认为该错误意味着您已多次声明具有相同名称的资源，该资源位于同一个tf文件中或您运行terraform的同一目录中的另一个tf文件中。

Answer 2

您可以使用变量指定所需的数量，然后将其添加到队列的名称中。

resource "aws_sqs_queue" "terraform_queue" {
  count  = "${var.queue_count}"
  name                      = "terraform-example-queue-${count.index}"
  delay_seconds             = 90
  max_message_size          = 2048
  message_retention_seconds = 86400
  receive_wait_time_seconds = 10
  redrive_policy            = "{\"deadLetterTargetArn\":\"${aws_sqs_queue.terraform_queue_deadletter.arn}\",\"maxReceiveCount\":4}"
}
