Warning

If a target group is used in at least one backend group, you cannot delete it. First, you need to delete it from all backend groups.

To delete a target group:

Management console

CLI

Terraform

API

In the management console, select the folder where the target group was created.
Select Application Load Balancer.
In the left-hand panel, select Target groups.
Select the target group and click .
In the menu that opens, select Delete.

To do this with multiple groups, select the groups to delete from the list and click Delete at the bottom of the screen.
In the window that opens, click Delete.

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.

See the description of the CLI command to delete a target group:
```
yc alb target-group delete --help
```
Run this command:
```
yc alb target-group delete <target_group_name_or_ID>
```
To check the deletion, get a list of target groups by running the command:
```
yc alb target-group list
```

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.

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

Sample target group description in the Terraform configuration:

resource "yandex_alb_target_group" "foo" {
  name           = "<target_group_name>"

  target {
    subnet_id    = "<subnet_ID>"
    ip_address   = "<VM_1_internal_IP_address>"
  }

  target {
    subnet_id    = "<subnet_ID>"
    ip_address   = "<VM_2_internal_IP_address>"
  }

  target {
    subnet_id    = "<subnet_ID>"
    ip_address   = "<VM_3_internal_IP_address>"
  }
}

For more information about the yandex_alb_target_group resource parameters, see the Terraform provider documentation.

Apply the changes:
1. In the terminal, change to the folder where you edited the configuration file.
2. Make sure the configuration file is correct using the command:
```
terraform validate
```
  If the configuration is correct, the following message is returned:
```
Success! The configuration is valid.
```
3. Run the command:
```
terraform plan
```
  The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.
4. Apply the configuration changes:
```
terraform apply
```
5. Confirm the changes: type yes in the terminal and press Enter.
You can check the target group update in the management console or using this CLI command:
```
yc alb target-group list
```

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