Deleting a security group

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

1. See the description of the CLI command for deleting security groups:

   yc vpc security-group delete --help
   

2. Get a list of all security groups in the default folder:

   yc vpc security-group list
   

   Result:

   +----------------------+-------------+-------------+----------------------+
   |          ID          |    NAME     | DESCRIPTION |      NETWORK-ID      |
   +----------------------+-------------+-------------+----------------------+
   | enpkf7dbjonf******** | test-sg-cli |             | enpgkbe17td8******** |
   +----------------------+-------------+-------------+----------------------+
   

3. Select the network's ID or NAME.

4. Delete the network:

   yc vpc security-group delete test-sg-cli
   

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 documentation on the Terraform website or mirror website.

If you don't have Terraform, install it and configure the Yandex Cloud provider.

To delete a security group created with Terraform:

1. Open the Terraform configuration file and delete the fragment with the security group description.

   Example security group description in a Terraform

   ...
   resource "yandex_vpc_security_group" "test-sg" {
     name        = "Test security group"
     description = "Description for security group"
     network_id  = "${yandex_vpc_network.lab-net.id}"
   
     ingress {
       protocol       = "TCP"
       description    = "Rule description 1"
       v4_cidr_blocks = ["10.0.1.0/24", "10.0.2.0/24"]
       port           = 8080
     }
   
     egress {
       protocol       = "ANY"
       description    = "Rule description 2"
       v4_cidr_blocks = ["10.0.1.0/24", "10.0.2.0/24"]
       from_port      = 8090
       to_port        = 8099
     }
   }
   ...
   

2. In the command line, go to the directory with the Terraform configuration file.

3. Check the configuration using this command:

   terraform validate
   

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

   Success! The configuration is valid.
   

4. Run this command:

   terraform plan
   

   The terminal will display a list of resources with parameters. No changes will be made at this step. If the configuration contains any errors, Terraform will point them out.

5. Apply the configuration changes:

   terraform apply
   

6. Confirm the changes: type yes into the terminal and press Enter.

   You can check the update using the management console or this CLI command:

   yc vpc security-group list
   

Use the delete REST API method for the SecurityGroup resource or the SecurityGroupService/Delete gRPC API call and provide the ID of the security group being deleted in the securityGroupId request parameter.

To get the security group ID, use the list REST API method for the SecurityGroup resource or the SecurityGroupService/List gRPC API call and provide the folder ID in the folderId request parameter.

To learn how to find out the folder ID, see Getting the folder ID.
