Warning

You cannot delete a backend group used in an HTTP router or load balancer. First, you need to remove it from all HTTP routers and load balancers.

To delete a backend group:

Management console

CLI

Terraform

API

In the management console, select the folder with your backend group.
Select Application Load Balancer.
In the left-hand panel, select Backend groups.
Click next to the backend group name and select Delete.

To delete multiple backend groups at once, select them in 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 CLI yet, install and initialize it.

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

See the description of the CLI command for deleting a backend group:
```
yc alb backend-group delete --help
```
Run this command and specify the name of the backend group you want to delete:
```
yc alb backend-group delete --name <backend_group_name>
```
To check whether the group has been deleted, get a backend group list by running the command:
```
yc alb backend-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 do not have Terraform yet, install it and configure its Yandex Cloud provider.

Open the Terraform configuration file and delete the fragment describing your backend group.

Sample backend group description in the Terraform configuration:

resource "yandex_alb_backend_group" "test-backend-group" {
  name                     = "<backend_group_name>"

  http_backend {
    name                   = "<backend_name>"
    weight                 = 1
    port                   = 80
    target_group_ids       = ["<target_group_ID>"]
    load_balancing_config {
      panic_threshold      = 90
    }    
    healthcheck {
      timeout              = "10s"
      interval             = "2s"
      healthy_threshold    = 10
      unhealthy_threshold  = 15 
      http_healthcheck {
        path               = "/"
      }
    }
  }
}

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 backend group updates in the management console or using this CLI command:
```
yc alb backend-group list
```

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