HashiCorp Terraform 是一種基礎架構即程式碼 (IaC) 工具,可讓您佈建及管理雲端基礎架構。Terraform 提供稱為「供應商」的外掛程式,可讓您與雲端服務供應商和其他 API 互動。您可以使用 Terraform 供應商 Google Cloud,佈建及管理 Google Cloud 資源,包括備份和災難復原服務。
本頁面將介紹如何搭配使用 Terraform 與 Backup and DR Service,包括 Terraform 的運作方式簡介,以及一些有助於開始搭配使用 Terraform 與 Google Cloud的資源。您也可以找到備份和災難復原服務的 Terraform 參考文件連結、程式碼範例,以及使用 Terraform 佈建備份和災難復原服務資源的指南。

Terraform provides plugins called\n*providers* that let you interact with cloud providers and other APIs. You can\nuse the *Terraform provider for Google Cloud* to provision and manage\nGoogle Cloud resources, including Backup and DR Service.\n\nThis page introduces you to using Terraform with Backup and DR Service, including an\nintroduction to how Terraform works and some resources to help you get started using\nTerraform with Google Cloud. You'll also find links to Terraform reference docs for\nBackup and DR Service, code examples, and guides for using Terraform to provision\nBackup and DR Service resources.\n\nFor instructions on how to get started with Terraform for Google Cloud, see\n[Install and configure Terraform](/docs/terraform/install-configure-terraform) or the\n[Terraform for Google Cloud quickstart](/docs/terraform/create-vm-instance).\n\nHow Terraform works\n-------------------\n\nTerraform has a declarative and configuration-oriented syntax, which you can\nuse to describe the infrastructure that you want to provision in your\nGoogle Cloud project. After you author this configuration in one or more\nTerraform configuration files, you can use the Terraform CLI to apply this\nconfiguration to your Backup and DR Service resources.\n\nThe following steps explain how Terraform works:\n\n1. You describe the infrastructure you want to provision in a *Terraform\n configuration file*. You don't need to write code describing how to provision the infrastructure. Terraform provisions the infrastructure for you.\n2. You run the `terraform plan` command, which evaluates your configuration and generates an execution plan. You can review the plan and make changes as needed.\n3. You run the `terraform apply` command, which performs the following\n actions:\n\n 1. It provisions your infrastructure based on your execution plan by invoking the corresponding Backup and DR Service APIs in the background.\n 2. It creates a *Terraform state file*, which is a JSON file that maps the resources in your configuration file to the resources in the real-world infrastructure. Terraform uses this file to keep a record of the most recent state of your infrastructure, and to determine when to create, update, and destroy resources.\n 3. When you run `terraform apply`, Terraform uses the mapping in\n the state file to compare the existing infrastructure to the code, and make\n updates as necessary:\n\n - If a resource object is defined in the configuration file, but doesn't exist in the state file, Terraform creates it.\n - If a resource object exists in the state file, but has a different configuration from your configuration file, Terraform updates the resource to match your configuration file.\n - If a resource object in the state file matches your configuration file, Terraform leaves the resource unchanged.\n\nTerraform resources for Backup and DR Service\n---------------------------------------------\n\n*Resources* are the fundamental elements in the Terraform language. Each\nresource block describes one or more infrastructure objects, such as virtual\nnetworks or compute instances.\n\nThe following table lists the Terraform resources available for\nBackup and DR Service:\n\n\n\u003cbr /\u003e\n\nTerraform-based guides for Backup and DR Service\n------------------------------------------------\n\nThe following table lists Terraform-based how-to guides and tutorials for\nBackup and DR Service:\n\n\n\u003cbr /\u003e\n\nTerraform modules and blueprints for Backup and DR Service\n----------------------------------------------------------\n\nModules and blueprints help you automate provisioning and managing of\nGoogle Cloud resources at scale. A *module* is a\nreusable set of Terraform configuration files that creates a logical abstraction\nof Terraform resources. A *blueprint* is a package of deployable and reusable\nmodules, and a policy that implements and documents a specific solution.\n\nThe following table lists modules and blueprints related to\nBackup and DR Service:\n\n\n\u003cbr /\u003e\n\nWhat's next\n-----------\n\n- [Terraform code samples for Backup and DR Service](/docs/samples?language=terraform)\n- [Terraform on Google Cloud documentation](/docs/terraform)\n- [Google Cloud provider documentation in HashiCorp](https://registry.terraform.io/providers/hashicorp/google/latest/docs)\n- [Infrastructure as code for Google Cloud](/docs/terraform/iac-overview)"]]
