我第一次尝试使用 terragrunt。我遵循了参考https://terratest.gruntwork.io/docs/getting-started/quick-start/的目录结构。我想保留在我的环境文件夹中使用的重复 main.tf、outputs.tf 和 vars.tf 的 gid。以下是我面临的版本和错误。任何帮助将不胜感激。提前致谢。

Terragrunt 版本

terragrunt version v0.23.10

地形版本

Terraform v0.12.24

目录结构

terraform-live/
├── prod
│   └── resource_group
│   ├── main.tf
│   └── terragrunt.hcl
└── terragrunt.hcl

terraform-live/terragrunt.hcl 的内容

backend = "azurerm"
config = {
    key = "${path_relative_to_include()}/terraform.tfstate"
    resource_group_name = "common-rg"
    storage_account_name = "testsa01"
    container_name = "tfstate"
  }

}

terraform-live/prod/resource_group/main.tf 的内容

backend "azurerm" {}
}

terraform-live/prod/resource_group/terragrunt.hcl 的内容

terraform {
  source = "git::git@github.com:adi4dpeople/terraform_modules.git//resource_group?ref=v0.0.1"
}

# Include all settings from the root terragrunt.hcl file
include {
  path = find_in_parent_folders()
}

# These are the variables we have to pass in to use the module specified in the terragrunt configuration above
inputs = {
  location = "westus"
  rg_name  = "testrg01"
}

当我运行 terragrunt 计划时，出现以下错误：

Initializing the backend...

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

我已经在 terragrunt https://github.com/gruntwork-io/terragrunt/issues/1151上解决了这个 GitHub 问题的问题

我在尝试创建为Azure Kubernetes 集群分配拉取角色以使用托管系统标识从Azure 容器注册表中拉取映像时遇到了类似的问题

Azure 角色分配（outputs.tf文件）

output "acr_id" {
  value = azure_container_registry.acr.id
}

这被放在一个名为azure-role-assignment的模块目录中

但是，当我在我的测试环境（main.tf文件）中调用模块输出文件时：

# Create azure container registry
module "azure_container_registry" {
  source                   = "../modules/azure-container-registry"
  container_registry_name  = var.container_registry_name
  resource_group_name      = var.resource_group_name
  location                 = var.location
  sku                      = var.sku
  admin_enabled            = var.admin_enabled
}

# Create azure role assignment
module "azure_role_assignment" {
  source                   = "../modules/azure-role-assignment"
  scope                    = module.azure_container_registry.acr_id
  role_definition_name     = var.role_definition_name
  principal_id             = module.azure_kubernetes_cluster.principal_id
}

但是，当我运行 terraform apply 时，出现错误：

Error: Reference to undeclared resource

  on ../modules/azure-container-registry/outputs.tf line 2, in output "acr_id":
   2:   value = azure_container_registry.acr.id

A managed resource "azure_container_registry" "acr" has not been declared in
module.azure_container_registry.

这是我解决它的方法：

问题在于我如何定义文件arc_id中的值outputs.tf。而不是这个：

Azure 角色分配（outputs.tf文件）

output "acr_id" {
  value = azure_container_registry.acr.id
}

应该是这样的：

Azure role assignment (`outputs.tf` file)

output "acr_id" {
  value = azurerm_container_registry.acr.id
}

那是azurerm_container_registry.acr.id和不是azure_container_registry.acr.id

就这样。

我希望这有帮助
