如何重用 terraform 资源？

Question

我是 terraform 的新手。我想知道有没有办法重用资源？ 下面是我的代码。 下面是 main.tf，我在其中声明了一个模块。

module "deployments" {
  source = "./modules/odo_deployments"
  artifact_versions = local.artifact_versions
}

在 modules/odo_deployments 文件夹中，我有两个资源，除了不同的广告外，它们的功能完全相同。 有没有一种方法可以只使用一个资源并将 arguments (ad) 像 function 一样传递给该资源？

variable "artifact_versions" {
  description = "What gets injected by terraform at the ET level"
}

resource "odo_deployment" "incident-management-service-dev" {
    count = var.artifact_versions["incident-management-service"].version == "skip" ? 0 : 1
    ad = "phx-ad-1"
    alias = "cloud-incident-management-application"
    artifact {
        url = var.artifact_versions["incident-management-service"].uri
        build_tag = var.artifact_versions["incident-management-service"].version
        type = var.artifact_versions["incident-management-service"].type
    }

    flags = ["SKIP_UP_TO_DATE_NODES"]
}

resource "odo_deployment" "incident-management-service-dev-ad3" {
    count = var.artifact_versions["incident-management-service"].version == "skip" ? 0 : 1
    ad = "phx-ad-3"
    alias = "cloud-incident-management-application"
    artifact {
        url = var.artifact_versions["incident-management-service"].uri
        build_tag = var.artifact_versions["incident-management-service"].version
        type = var.artifact_versions["incident-management-service"].type
    }

    flags = ["SKIP_UP_TO_DATE_NODES"]
}

我为解决这个问题所做的是，我在 main.tf 中添加了一个局部变量，并在模块中传递局部变量，如下所示

locals {
  ad = ["phx-ad-1", "phx-ad3"]
}
module "deployments" {
  source = "./modules/odo_deployments"
  artifact_versions = local.artifact_versions
  ad = local.ad

在资源中，我没有对广告价值进行硬编码，而是像下面这样使用它

count = length(var.ad)
ad    = var.ad[count.index]
