使用 Terraform 管理 Service Usage 资源
本文档介绍如何使用 Terraform 预配服务使用资源，例如配额覆盖。
要管理使用方配额替换值，您可以使用 google_service_usage_consumer_quota_override 架构来指定 Terraform 配置文件中的资源并运行 Terraform 命令来应用更改。
准备工作
查看服务配额模型，其中介绍了本教程中使用的术语。
配置 Terraform 和凭据：
创建使用方配额替换值
创建配置文件：
转到您的工作目录。
将以下内容复制并粘贴到名为 main.tf 的新文件中。
resource "google_service_usage_consumer_quota_override" "regional_override" { provider = google-beta dimensions = { region = "us-central1" } project = PROJECT_ID service = "libraryagent.googleapis.com" metric = "libraryagent.googleapis.com%2Fread_requests_regional" limit = "%2Fmin%2Fproject%2Fregion" override_value = "8" force = true } resource "google_service_usage_consumer_quota_override" "cd_override" { provider = google-beta dimensions = { author = "larry" } project = PROJECT_ID service = "libraryagent.googleapis.com" metric = "libraryagent.googleapis.com%2Fborrows" limit = "%2Fauthor%2Fproject" override_value = "8" force = true }您放入
main.tf文件中的内容包含两个使用方替换项的配置信息："regional_override"和"cd_override"。有关每个字段的说明，请参阅参数参考。初始化工作目录。
terraform init -upgrade应用 Terraform 配置。
terraform applyTerraform 会检查当前状态并将其与配置文件中的信息进行比较。比较完成后，Terraform 会输出更改列表，然后提供继续或取消应用更改的选项。

修改使用方配额替换
- 如需修改替换值，请修改
main.tf文件并更改override_value字段的值。 应用 Terraform 配置。
terraform apply
删除使用方配额替换值
如需删除使用方配额替换值，请从 main.tf 文件中移除相应的资源块。您可以移除多个替换值。如需移除所有覆盖，请确保 main.tf 文件为空。
应用 Terraform 配置。
terraform apply例如，删除先前配置的区域替换。删除引用资源的块：

状态文件
您可能会注意到，工作目录中有两个生成的文件：terraform.tfstate 和 terraform.tfstate.backup。在您执行最新的 terraform apply 后，第一个文件会记录您的基础架构的当前状态。第二个文件会记录最新 terraform apply 之前的状态。如需详细了解 Terraform 状态，请参阅其官方文档。
如果您已按照本页面中的步骤进行操作，则以下内容位于 terraform.tfstate 文件中，我们的基础架构中还剩 cd_override。
