如何在AWS资源的标签中获得Terragrunt.hcl的相对路径？

Question

如何用其源/

terragrunt.hcl

文件的相对路径标记每个AWS资源？理想情况下，该解决方案（如果存在）也将与本地/相对引用的模块一起使用（而不仅仅是来自GIT回购的模块）。

# In root terragrunt.hcl
locals {
  # ...
  aws_default_tags = jsonencode({  # This is line 48 in the error below.
    ManagedBy = "Terraform"
    TerraformBasePath = path.cwd  # What is a (working) equivalent of this?
  )}
}

generate "provider" {
  # ...
  contents  = <<EOF
provider "aws" {
  # ...
  default_tags {
    tags = jsondecode(<<INNEREOF
${local.aws_default_tags}
INNEREOF
)
  }

}
EOF
}

在

terragrunt apply

上的错误，root上述错误：

terragrunt.hcl

通过简化问题中的第一个片段，将相对路径添加为标签：

Answer 1

嵌套函数可以使用一些简化。

这是一个很好的问题。我发现在资源标签中看到的IAC路径是“资源”配置所在的IAC路径。

我测试的解决方案就是这样：

在root terragrunt.hcl文件中，来自project_name/terragrunt.hcl

（推荐是使用root.hcl代替terragrunt.hcl：

Answer 2

# In root terragrunt.hcl
locals {
  # ...
# terraform-git-repo = "infrastructure"  # For future use in CD pipeline.
  terraform-git-repo = "/local/path/infra"
}

generate "provider" {
  # ...
  contents  = <<EOF
provider "aws" {
  # ...
  default_tags {
    tags = {
      Terraform-base-path = replace(replace(path.cwd, "${local.terraform-git-repo}", ""), "/.terragrunt-cache/.*/", "")
    }
  }

}
EOF
}

Whather

replace

，

locals {
  account_vars     = read_terragrunt_config(find_in_parent_folders("account.hcl"))
}
inputs = merge(
  local.account_vars.locals,
  local.region_vars.locals,
  local.environment_vars.locals,
  {
    custom_tags        = "${local.aws_mandatory_tags}",
    tags               = "${local.aws_mandatory_tags}",
    aws_mandatory_tags = "${local.aws_mandatory_tags}",
  }
)

和custom_tags是Terraform块中使用的Terraform模块的变量。

在project_name/emoverition/account.hcl

：

tags

aws_mandatory_tags

我的计划显示：

# For IaC relative path to be added in tags
  full_path_iac_repo_for_tags     = get_original_terragrunt_dir()
  iac_repo_root                   = dirname(get_terragrunt_dir()) # this depends on the IaC repo directory structure
  relative_path_iac_repo_for_tags = replace(local.full_path_iac_repo_for_tags, local.iac_repo_root, "")
