ApsaraDB RDS:Use Terraform in Cloud Shell

Procedure

1. Access Cloud Shell by using a browser.
   Note For more information about how to use Cloud Shell, see Use Cloud Shell.

   
2. Create an execution directory and access the directory.
   Note You must create an execution directory for each Terraform project.

   mkdir /usr/local/terraform
   cd /usr/local/terraform

3. Use the vim command to compile the Terraform template file named terraform.tf.
   To query the zone information, run the following command:

   vim terraform.tf

   In this example, add the following information to the file:

   data "alicloud_db_zones" "queryzones" {
     instance_charge_type= "PostPaid"
     engine = "PostgreSQL"
     db_instance_storage_type = "cloud_essd"
   }

   Note After the vim command is configured, press Esc and enter :wq to save the configuration and exit.
4. Run the terraform init command to initialize the configuration.
   Sample output:

   shell@Alicloud:/usr/local/terraform$ terraform init
   
   Initializing the backend...
   
   Initializing provider plugins...
   - Checking for available provider plugins...
   - Downloading plugin for provider "alicloud" (hashicorp/alicloud) 1.186.0...
   
   The following providers do not have any version constraints in configuration,
   so the latest version was installed.
   
   To prevent automatic upgrades to new major versions that may contain breaking
   changes, it is recommended to add version = "..." constraints to the
   corresponding provider blocks in configuration, with the constraint strings
   suggested below.
   
   * provider.alicloud: version = "~> 1.186"
   
   
   Warning: registry.terraform.io: For users on Terraform 0.13 or greater, this provider has moved to aliyun/alicloud. Please update your source in required_providers.
   
   
   Terraform has been successfully initialized!
   
   You may now begin working with Terraform. Try running "terraform plan" to see
   any changes that are required for your infrastructure. All Terraform commands
   should now work.
   
   If you ever set or change modules or backend configuration for Terraform,
   rerun this command to reinitialize your working directory. If you forget, other
   commands will detect it and remind you to do so if necessary.

5. Run the terraform plan command to preview the configuration.
   Sample output:

   shell@Alicloud:/usr/local/terraform$ terraform plan
   Refreshing Terraform state in-memory prior to plan...
   The refreshed state will be used to calculate this plan, but will not be
   persisted to local or remote state storage.
   
   data.alicloud_db_zones.queryzones: Refreshing state...
   
   ------------------------------------------------------------------------
   
   No changes. Infrastructure is up-to-date.
   
   This means that Terraform did not detect any differences between your
   configuration and real physical resources that exist. As a result, no
   actions need to be performed.

6. Run the terraform apply command to apply the configuration.
   Sample output:

   shell@Alicloud:/usr/local/terraform$ terraform apply
   data.alicloud_db_zones.queryzones: Refreshing state...
   
   Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

7. Run the terraform show command to query the result.
   Sample output:

   shell@Alicloud:/usr/local/terraform$ terraform show
   # data.alicloud_db_zones.queryzones:
   data "alicloud_db_zones" "queryzones" {
       db_instance_storage_type = "cloud_essd"
       engine                   = "PostgreSQL"
       id                       = "491248936"
       ids                      = [
           "cn-hangzhou-g",
           "cn-hangzhou-h",
           "cn-hangzhou-i",
           "cn-hangzhou-j",
           "cn-hangzhou-k",
       ]
       instance_charge_type     = "PostPaid"
       multi                    = false
       multi_zone               = false
       zones                    = [
           {
               id             = "cn-hangzhou-g"
               multi_zone_ids = []
           },
           {
               id             = "cn-hangzhou-h"
               multi_zone_ids = []
           },
           {
               id             = "cn-hangzhou-i"
               multi_zone_ids = []
           },
           {
               id             = "cn-hangzhou-j"
               multi_zone_ids = []
           },
           {
               id             = "cn-hangzhou-k"
               multi_zone_ids = []
           },
       ]
   }
