Create a Terraform template

Scenarios

To manage resources from multiple cloud platforms, such as AWS and Azure, on Alibaba Cloud, you can define the resources and their dependencies in a template. This method simplifies resource management in a multicloud environment.

Procedure

1. Log on to the ROS console.

2. In the navigation pane on the left, choose Templates > My Templates.

3. On the My Templates page, click Create Template.

4. For Template Type, select Terraform.

5. Create a Terraform template.

   The following example shows how to create a vSwitch in a virtual private cloud (VPC).

   1. Create the modules/vpc/main.tf file and add content to the file to create a VPC.

      1. To the right of the directory, click + and then click Create Folder.

      2. In the Create Folder dialog box, enter modules to create a folder named modules.

      3. Hover the pointer over the modules folder, click + on the right, and then click Create Folder.

      4. In the Create Folder dialog box, enter vpc to create a subfolder named vpc in the modules folder.

      5. Hover the pointer over the vpc folder, click + on the right, and then click Create File.

      6. In the Create File dialog box, enter main.tf to create a main.tf file in the vpc folder.

      7. Click main.tf and enter the following code in the editor on the right to create a VPC.

         resource "alicloud_vpc" "vpc" {
           name       = "tf_test"
           cidr_block = "172.16.0.0/12"
         }
         output "vpc_id" {
           value = "${alicloud_vpc.vpc.id}"
         }

         

   2. Edit the main.tf file in the root directory to create a vSwitch in the VPC.

      1. Click the main.tf file in the root directory.

      2. In the editor on the right, enter the following code to create a vSwitch.

         module "my_vpc" {
           source      = "./modules/vpc"
         }
         resource "alicloud_vswitch" "vsw" {
           vpc_id            = "${module.my_vpc.vpc_id}"
           cidr_block        = "172.16.0.0/21"
           availability_zone = "cn-shanghai-b"
         }
         output "vsw_id" {
           value = "${alicloud_vswitch.vsw.id}"
         }

         

6. In the lower-left corner of the Create Template page, choose Save Template > Save as My Template.

7. In the Save as My Template dialog box, set the Template Name, Template Description, Resource Group, and Tags.

8. Click OK.
