Terraform 参数块作为地图列表

Question

我正在尝试在我的 query_string 元组中获取这两个元素。但是，只有最后一个元素被拾取。下面是我的 test/main.tf 文件：

terraform {
  required_version = ">= 0.13.0"

  required_providers {
    aws = ">= 3.58"
  }
}

provider "aws" {
  region = "us-east-1"
}

module "test_module" {
  source = "../"

  lb = [
    {
      name                       = "lb-name"
      enable_deletion_protection = true
      internal                   = false
      load_balancer_type         = "application"

      lb_listener = [
        {
          port       = "8080"
          protocol   = "HTTP"
          ssl_policy = "ELBSecurityPolicy-2016-08"

          default_action = {
            type  = "redirect"
            order = 1

            redirect = {
              status_code = "HTTP_302"
            }
          }

          lb_listener_rule = [
            {
              action = {
                type = "fixed-response"

                fixed_response = {
                  content_type = "text/plain"
                  message_body = "This is a message body."
                }
              }

              condition = {
                query_string = [
                  {
                    key   = "health"
                    value = "check"
                  },
                  {
                    value = "bar"
                  }
                ]
              }
            }
          ]
        }
      ]
    }
  ]
}

这是我的 lb.tf 文件：

这是我运行terraform plan 时condition 块的外观：

condition {
  query_string {
    value = "bar"
  }
}

这是我希望 condition 块的外观：

condition {
  query_string {
    key   = "health"
    value = "check"
  }

  query_string {
    value = "bar"
  }
}

您的代码虽然复杂，但正确创建了两个query_string：

问题中发布的表单中的代码有问题数量，它不起作用。但是当您写道“我的原始文件很长。”时，我猜您的真实代码确实有效。因此我只关注它的验证，而不是修复所有可能的错误，因为我不知道你的实际代码是什么。
