Terraform错误“预配置的并发配置无法应用于未发布的函数版本”-如何解决？

Question

我尝试创建一个预置的并发Lambda，如下所示：

locals {
  lambda_name = "mylambda"
  provisioned_concurrency = 10
}

module "mylambda-lambda" {
  source = "terraform-aws-modules/lambda/aws"
 
  function_name = "${var.environment_name}-${local.lambda_name}"
  // abriged config detailes
}


module "mylambda-alias" {
  source = "terraform-aws-modules/lambda/aws//modules/alias"
  name = local.lambda_name
  function_name = module.mylambda-lambda.this_lambda_function_name
}

resource "aws_lambda_provisioned_concurrency_config" "auth_authorizer" {
  function_name = module.mylambda-lambda.this_lambda_function_name
  provisioned_concurrent_executions = local.provisioned_concurrency
  qualifier = module.mylambda-alias.this_lambda_alias_name
}

它在控制台中显示一个限定符(显然是别名)被设置为$LATEST。

但是使用并发设置时，我得到了一个错误

Error: error putting Lambda Provisioned Concurrency Config (<lambda name>): InvalidParameterValueException: Provisioned Concurrency Configs cannot be applied to unpublished function versions.
{
  RespMetadata: {
    StatusCode: 400,
    RequestID: "392f5609-086e-43f6-89af-a0ec0f7e3dc7"
  },
  Message_: "Provisioned Concurrency Configs cannot be applied to unpublished function versions.",
  Type: "User"
}

如何避免这个错误？

Answer 1

正如@jellycsc所指出的，您需要发布一个新版本。

为此，您已经使用了terraform aws模块，该模块接受标志publish

module "mylambda-lambda" {
  source = "terraform-aws-modules/lambda/aws"
  publish = true
 
  function_name = "${var.environment_name}-${local.lambda_name}"
  // abriged config detailes
}
