Create the Compartments Module

Define each compartment as a resource, and declare the required variables.

Complete the following steps in the compartments subdirectory:

1. Create a text file named variables.tf, and paste the following code in the file.
   This code declares the variables used in this module.

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

2. Create a text file named compartments.tf, and paste the following code in the file.

   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. Create a text file named compartments_output.tf, and paste the following code in the file.
   This code causes Terraform to display the IDs of the compartments, after they are created.

   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}"
   }
