建立區間模組

將每個區間定義為資源，並宣告必要的變數。

完成 compartments 子目錄中的下列步驟：

1. 建立名為 variables.tf 的文字檔，然後將下列程式碼貼到檔案中。
   此代碼會宣告此模組中使用的變數。

   variable "tenancy_ocid" {}
   variable "app_tag" {}
   variable "environment" {}

2. 建立名為 compartments.tf 的文字檔，然後將下列程式碼貼到檔案中。

   resource "oci_identity_compartment" "networks" {
     description = "The networks compartment"
     name        = "${var.app_tag}_${var.environment}_networks"
   }
   
   resource "oci_identity_compartment" "admin" {
     description = "The admin compartment"
     name        = "${var.app_tag}_${var.environment}_admin"
   }
   
   resource "oci_identity_compartment" "shared_services" {
     description = "The shared_services compartment"
     name        = "${var.app_tag}_${var.environment}_shared_services"
   }
   
   resource "oci_identity_compartment" "business_logic" {
     description = "The business_logic compartment"
     name        = "${var.app_tag}_${var.environment}_business_logic"
   }
   
   resource "oci_identity_compartment" "database" {
     description = "The database compartment"
     name        = "${var.app_tag}_${var.environment}_database"
   }
   

3. 建立名為 compartments_output.tf 的文字檔，然後將下列程式碼貼到檔案中。
   此代碼會造成 Terraform 在建立區間之後顯示區間的 ID。

   output "networks_id" {
     value = "${oci_identity_compartment.networks.id}"
   }
   
   output "admin_id" {
     value = "${oci_identity_compartment.admin.id}"
   }
   
   output "shared_services_id" {
     value = "${oci_identity_compartment.shared_services.id}"
   }
   
   output "business_logic_id" {
     value = "${oci_identity_compartment.business_logic.id}"
   }
   
   output "database_id" {
     value = "${oci_identity_compartment.database.id}"
   }
