将列表与地形中的地图合并

Question

我正在编写terraform脚本来自动提供acm域，我面临的问题是如何合并域和subject_alternative_names，就像它应该从domain_name中选择第一个域并将其与subject_alternative_name中的第一个块合并并继续。

Variable.tf

variable "domain_name" {
description = "Configuration for alb settings"
default = [
"domain.com",
"helloworld.com",
"helloworld2.com",
]
}
variable "subject_alternative_names" {
description = "subject_alternative_names"
default = [ {
domain.com = {
"domain.com",
"domain2.com",
"domain3.com",
},
helloworld.com = {
"helloworld1.com",
"helloworld2.com"
},
hiworld.com = {
"hiworld1.com",
"hiworld2.com"
}
}]
}
variable "region" {
description = "name of the region"
default     = "us-east-1"
}
variable "validation_method" {
description = "name of the region"
default     = "DNS"
}
variable "tags" {
description = "name of the region"
default     = "Test"
}

工作variable.tf

variable "domain_name" {
description = "Configuration for alb settings"
default     = [
"domain.com",
"helloworld.com",
"helloworld2.com",
"helloworld1.com",
"helloworld3.com",
]
}
variable "subject_alternative_names"{
description = "subject_alternative_names"
default     = [
"domain.com",
"helloworld.com",
"helloworld2.com",
"helloworld1.com",
"helloworld3.com",
]
}
variable "region" {
description = "name of the region"
default     = "us-east-1"
}
variable "validation_method" {
description = "name of the region"
default     = "DNS"
}
variable "tags" {
description = "name of the region"
default     = "Test"
}

main.tf

module "acm" {
count                     = length(var.domain_name)
source                    = "./modules/acm"
domain_name               = var.domain_name[count.index]
validation_method         = var.validation_method
tags                      = var.tags
subject_alternative_names = var.subject_alternative_names
}

resource.tf

variable "domain_name" {
default     = ""
description = "Nmae of the domain"
}
variable "validation_method" {
default     = ""
description = "Validation method DNS or EMAIL"
}
variable "tags" {
default     = ""
description = "tags for the ACM certificate"
}
variable "subject_alternative_names" {
default     = ""
description = "subject_alternative_names"
}
resource "aws_acm_certificate" "acm_cert" {
domain_name               = var.domain_name
validation_method         = var.validation_method
subject_alternative_names = var.subject_alternative_names
lifecycle {
create_before_destroy = true
}
tags = {
Name = var.tags
}
}

最简单的方法是使用单个映射:

variable "domain_name_with_alternate_names" {
default = {
"domain.com" = [
"domain.com",
"domain2.com",
"domain3.com",
],
"helloworld.com" = [
"helloworld1.com",
"helloworld2.com"
],
"hiworld.com" = [
"hiworld1.com",
"hiworld2.com"
],
"hiwodd4.com" = []
}
}

module "acm" {
for_each                  = var.domain_name_with_alternate_names

source                    = "./modules/acm"
domain_name               = each.key
validation_method         = var.validation_method
tags                      = var.tags
subject_alternative_names = each.value
}
