Question

“”虽然我正在使用terraform创建s3存储桶的vpc流日志模块，但其抛出错误如下：此处不应使用名为“ flow_log_destination_type”的参数。此处不应使用名为“ flow_log_destination_arn”的参数。在Terraform文档中，我可以看到要填充的详细信息，例如log_destination_type和log_destination_arn，并且我在GitHub上找到了一些文档，它们完全说出了相同的代码，但是在尝试时对我不起作用

产生以下错误：

Error: Unsupported argument

  on main.tf line 52, in module "vpc_with_flow_logs_s3_bucket":
  52:   flow_log_destination_type = "s3"

An argument named "flow_log_destination_type" is not expected here.


Error: Unsupported argument

  on main.tf line 53, in module "vpc_with_flow_logs_s3_bucket":
  53:   flow_log_destination_arn  = "${aws_s3_bucket.terra-test2-lifecycle.arn}"

An argument named "flow_log_destination_arn" is not expected here.


Error: Unsupported argument

我在哪里做错了？”

    transition {
      days          = 30
      storage_class = "STANDARD_IA" # or "ONEZONE_IA"

为什么Terraform失败并显示“这里不应该有一个名为“ flow_log_destination_type”的参数”？

Answer 1

如果传递模块不期望的变量，则会发生此错误。

例如

module "vpc_with_flow_logs_s3_bucket" {
  source = "../../"
  log_destination_type = "s3"
  log_destination_arn  = "${flow_log_destination_arn}"

  vpc_flow_log_tags = {
    Name = "vpc-flow-logs-s3-bucket"
  }

}

如果您指定此选项，则如果在main.tf中定义了flow_log_destination_arn变量，而在未在variables.tf中定义了变量，则将引发错误。

来源： ../../ vpc_with_flow_logs_s3_bucket / main.tf

resource "aws_flow_log" "example" { iam_role_arn = "${aws_iam_role.example.arn}" log_destination = "${aws_cloudwatch_log_group.example.arn}" traffic_type = "ALL" vpc_id = "${aws_vpc.example.id}" }

Answer 2

位于“ ../../”的模块未声明任何 log_destination_type ， log_destination_arn 或 vpc_flow_log_tags 变量和Terraform认为在这样的模块块中分配未声明的变量是错误的：

module "vpc_with_flow_logs_s3_bucket" {
  source = "../../"
  log_destination_type = "s3"
  log_destination_arn  = "${flow_log_destination_arn}"

  vpc_flow_log_tags = {
    Name = "vpc-flow-logs-s3-bucket"
  }
}

“ ../../”最有可能是 vpc_with_flow_logs_s3_bucket 模块的错误源路径，您应该对此进行修复。如果您位于声明了此模块块的模块的源路径中，并且运行cd ../../，您是否会使用 vpc_with_flow_logs_s3_bucket Terraform代码进入目录？如果不是，则源设置不正确，您需要对其进行修复。

如果“ ../../”是正确的路径，则应添加缺少的变量声明。

variable "log_destination_type" {
    type = string
}

variable "log_destination_arb" {
    type = string
}

variable "vpc_flow_log_tags" {
    type = map(string)
}

Answer 3

我将分享此错误的另一个可能原因。

这样编写配置块：

  scaling_config = {
    desired_size = 2
    max_size     = 2
    min_size     = 2
  }

代替（注意=等号）：

  scaling_config {
    desired_size = 2
    max_size     = 2
    min_size     = 2
  }

将给出错误An argument named "scaling_config" is not expected here。

（*）请注意，更改后，如果确实不支持块类型，则错误标题将更改为：

Error: Unsupported argument

收件人：

Error: Unsupported block type

错误消息为：

Blocks of type "scaling_config" are not expected here.
