Deleting a WAF exclusion rule

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.

1. Open the Terraform configuration file and delete the exclusion_rule section defining your WAF exclusion rule from the yandex_sws_waf_profile description.

   Example of an exclusion rule description in the Terraform configuration

   # WAF profile
   resource "yandex_sws_waf_profile" "default" {
     name = "waf-profile-default"
     core_rule_set {
       inbound_anomaly_score = 2
       paranoia_level        = local.waf_paranoia_level
       rule_set {
         name    = "OWASP Core Ruleset"
         version = "4.0.0"
       }
     }
   
     ...
   
     # Exclusion rule
     exclusion_rule {
       name = "<exclusion_rule_name>"
       exclude_rules {
         exclude_all = <true_or_false>
         rule_ids    = ["rule_1_ID","rule_2_ID"]
       }
     }
   }
   

   For more information about sws_waf_profile properties, see this Terraform provider article.

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 update REST API method for the WafProfile resource or the WafProfile/Update gRPC API call.
