地图变量中的局部变量

Local variables inside map variables

我正在尝试使用映射变量(它有 2 个 lambda 名称)。另外,我想在键值内传递一个局部变量,如示例 below.However 所示,我收到一个错误,因为此处不允许使用变量。任何 suggestions/advice?

variables.tf:

variable "lambdas" {
type = map(string)
default = {
"lambda1_name-${local.global_suffix}"   = "lambda_function1",
"lambda2_name-${local.global_suffix}" = "lambda_function2"
}
}

locals{
global_suffix   = "${var.env}-${var.project}${var.branch_hash}"
}

main.tf:

resource "aws_lambda_function" "main" {
for_each         = var.lambdas
function_name    = each.key
handler          = "${each.value}.${var.handler}"
filename         = "${path.module}/modules/lambda-main/${each.value}.zip"
source_code_hash = data.archive_file.init[each.key].output_base64sha256
role             = module.lambda_iam_role.arn
runtime          = "python3.6"
memory_size      = "2048"
timeout          = "900"
tags             = local.tags
description      = "${var.project} Lambda Function"
}

我正在尝试使用一个 lambda 资源块来创建 2 个 lambda 函数(因此使用 map 变量)

您的变量默认值不能动态。它们必须是静态值。因此,在您的情况下,与其使用 var.lambdas,不如使用 locals:

variable "lambdas" {
  type = map(string)
    default = {
    "lambda1_name" = "lambda_function1",
    "lambda2_name" = "lambda_function2"
  }
}

locals {
  lambdas = {for key, value in var.lambdas: "${key}-${local.global_suffix}" => value}
}

你会:'

resource "aws_lambda_function" "main" {
    for_each         = local.lambdas
    ....
}
