如何使用位于呼叫者模块外层的模块的输出？

我正在与Terraform合作一段时间，但我一直没有遇到任何问题，因为我总是遵循一个简单的结构。但是现在，我开始研究另一个似乎并没有遵守最佳实践的项目。

项目结构就是这样：

> root-folder
   > modules
      > cloudfront
      > route53
      > team1
         > service1
            - main.tf
            - variables.tf
            - locals.tf

我要做的是，使用模块

module "record" {
  source      = "../../route53"
  zone_id     = var.route53_zone_id
  record_name = local.record_name
  cdn_id       = module.cloudfront.some_output_value   //the question is about this line
}

。无法使用它，因为IDE表示 no module.cloudfront 。

有人知道为什么我不能使用在外部范围上定义的模块吗？

Terraform版本：1.2.0（这可能与基于版本的问题无关，但无论如何。）

I'm working with terraform for a while and I didn't face any issues as I always followed a simple structure.
But now I've started working on another project that doesn't seem like it adheres to best practices.

The project structure is like this:

> root-folder
   > modules
      > cloudfront
      > route53
      > team1
         > service1
            - main.tf
            - variables.tf
            - locals.tf

And what I'm trying to do is, use modules.cloudfront.some_output_value within the modules>team1>service1>main.tf file as seen below:

module "record" {
  source      = "../../route53"
  zone_id     = var.route53_zone_id
  record_name = local.record_name
  cdn_id       = module.cloudfront.some_output_value   //the question is about this line
}

But I'm unable to use it, since the IDE indicates there is no such module as module.cloudfront.

Does anyone know why I cannot use a module that is defined at an outer scope?

Terraform version: 1.2.0 (probably this's not related to a version based issue, but anyway.)

这取决于您调用cloudfront模块的位置。

选项1

如果您调用两个模块，service1和cloudfront从同一父母进行值：

service1 （应将其分配到variables.tf和main.tf当然。）

variable "cdn_id" {
  type        = ...
  description = "..."
}

module "record" {
  source       = "../../route53"
  zone_id      = var.route53_zone_id
  record_name  = local.record_name
  cdn_id       = var.cdn_id
}

parent模块 （例如，在root文件夹中）

module "service1" {
  source        = "modules/team1/service1"
  cdn_id        = module.cloudfront.some_output_value
  some_var_name = some_value
  ...
}

module "cloudfront" {
  source        = "modules/cloudfront"
  some_var_name = some_value
  ...
}

选项2

如果您从service1调用它，则文件层次结构中模块的位置无关紧要。您只需要正确设置源路径：

module "record" {
  source       = "../../route53"
  zone_id      = var.route53_zone_id
  record_name  = local.record_name
  cdn_id       = module.cloudfront.some_output_value
}

module "cloudfront" {
  source        = "../../cloudfront"
  some_var_name = some_value
  ...
}

It depends from where you invoke the cloudfront module.

Option 1

If you invoke both modules, service1 and cloudfront from the same parent, then you need to define a variable in service1 and explicitly pass the value:

service1 (Should be splitted into variables.tf and main.tf of course.)

variable "cdn_id" {
  type        = ...
  description = "..."
}

module "record" {
  source       = "../../route53"
  zone_id      = var.route53_zone_id
  record_name  = local.record_name
  cdn_id       = var.cdn_id
}

parent module (e.g. in root folder)

module "service1" {
  source        = "modules/team1/service1"
  cdn_id        = module.cloudfront.some_output_value
  some_var_name = some_value
  ...
}

module "cloudfront" {
  source        = "modules/cloudfront"
  some_var_name = some_value
  ...
}

Option 2

If you invoke it from service1, then the location of the module in the file hierarchy does not matter. You just have to set the source path right:

module "record" {
  source       = "../../route53"
  zone_id      = var.route53_zone_id
  record_name  = local.record_name
  cdn_id       = module.cloudfront.some_output_value
}

module "cloudfront" {
  source        = "../../cloudfront"
  some_var_name = some_value
  ...
}
