Deleting an ARL profile

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the relevant documentation on the Terraform website or its mirror.

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

To delete an ARL profile created with Terraform:

1. Open the Terraform configuration file and delete the section describing the yandex_sws_advanced_rate_limiter_profile resource:

   Example of an ARL profile description in the Terraform configuration

   # ARL profile
   
   resource "yandex_sws_advanced_rate_limiter_profile" "arl-profile" {
     name        = "<profile_name>"
     description = "<profile_description>"
   
     # Rule 1
   
     advanced_rate_limiter_rule {
       name        = "<rule_name>"
       priority    = <rule_priority>
       description = "<rule_description>"
       dry_run     = true
   
       static_quota {
         action = "DENY"
         limit  = <rule_limit>
         period = <rule_period>
         condition {
           request_uri {
             path {
               exact_match = "/api"
             }
           }
         }
       }
     }
   }
   

   Where:

   • name: ARL profile name.

   • advanced_rate_limiter_rule: Rule section.
     • name: Rule name.
     • priority: Rule priority, a unique number from 1 to 999999. Rules with smaller numerical values apply first.
     • description: Rule description. This is an optional setting.
     • dry_run: Dry run flag. Set it to true to test the rule and estimate the load on your web service. Requests will not be blocked in this mode. However, the system will log triggered rules. This is an optional setting.
     • static_quota: Request count mode where each request is counted individually without grouping. You can only specify either static_quota or dynamic_quota.
       • action: Action if the limit is exceeded. Always set it to DENY.
       • limit: Maximum number of allowed requests per period.
       • period: Time period in seconds during which the limit applies.
       • condition: Condition for applying the rule. This is an optional setting. For more information, see the advanced_rate_limiter_rule.static_quota.condition description in this provider article.
     • dynamic_quota: Request count mode where groups of requests sharing one or more properties are counted. You can only specify either static_quota or dynamic_quota.
       • action: Action if the limit is exceeded. Always set it to DENY.
       • limit: Maximum number of allowed requests per period.
       • period: Time period in seconds during which the limit applies.
       • condition: Condition for applying the rule. This is an optional setting. For more information, see the advanced_rate_limiter_rule.dynamic_quota.condition description in this provider article.
       • characteristic: Description of properties to group requests by. You can only specify either simple_characteristic or key_characteristic.
         • case_insensitive: Case insensitive, if true, or sensitive, if false.
         • key_characteristic: Section of parameters requiring a key (string) to group requests by.
           • type: Grouping type. The possible values are COOKIE_KEY, HEADER_KEY, and QUERY_KEY.
           • value: Key value (string) to group requests by.
         • simple_characteristic: Section with parameters for autogrouping, i.e., requests are automatically grouped by the specified parameter.
           • type: Grouping type. The possible values are REQUEST_PATH, HTTP_METHOD, IP, GEO, and HOST.

2. Apply the changes:

   1. In the terminal, go to the directory where you edited the configuration file.

   2. Make sure the configuration file is correct using this command:

      terraform validate
      

      If the configuration is correct, you will get this message:

      Success! The configuration is valid.
      

   3. Run this command:

      terraform plan
      

      You will see a detailed list of resources. No changes will be made at this step. If the configuration contains any errors, Terraform will show them.

   4. Apply the changes:

      terraform apply
      

   5. Type yes and press Enter to confirm the changes.

   You can check the deletion of the resources in the management console.

Use the delete REST API method for the AdvancedRateLimiterProfile resource or the AdvancedRateLimiterProfile/Delete gRPC API call.
