Deleting a backend group

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.
Navigate to Application Load Balancer.
In the left-hand panel, select Backend groups.
Click next to the backend group name and 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 CLI yet, install and initialize it.

The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

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 guides on the Terraform website or its mirror.

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

To manage infrastructure using Terraform under a service account or user accounts (a Yandex account, a federated account, or a local user), authenticate using the appropriate method.

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               = "/"
      }
    }
  }
}

For more on the properties of the yandex_alb_backend_group resource, see this provider guide.

Apply the changes:
1. In the terminal, navigate to the configuration file directory.
2. Make sure the configuration is correct using this command:
```
terraform validate
```
  If the configuration is valid, you will get this message:
```
Success! The configuration is valid.
```
3. Run this command:
```
terraform plan
```
  You will see a list of resources and their properties. No changes will be made at this step. Terraform will show any errors in the configuration.
4. Apply the configuration changes:
```
terraform apply
```
5. Type yes and press Enter to confirm the changes.
You can check the backend group updates in the management console or using this CLI command:
```
yc alb backend-group list
```
Timeouts
The Terraform provider limits operations with Application Load Balancer backend groups to 10 minutes.

Operations in excess of this time will be interrupted.
How do I modify these limits?
Add a timeouts section to the backend group description:

resource "yandex_alb_backend_group" "<backend_group_name>" { ... timeouts { create = "60m" update = "60m" delete = "60m" } }

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