Creating an origin group

To create an origin group:

Management console

CLI

Terraform

API

In the management console, select the folder to host your origin group.
Select Cloud CDN.
If the CDN provider is not activated yet, click Activate provider. A connection will be established automatically.

If you do not see the Activate provider button and you can create resources and origin groups, it means that the provider is already activated. Proceed to the next step.
In the left-hand panel, select Origin groups.
Click Create origin group.
Enter a name for the origin group.
Configure Origin:
- Specify the Origin type: Server, Bucket, or L7 load balancer. For more information about types, see Origins and origin groups.
- Specify an origin.
- Select the Priority: Active or Backup. For more information about priorities, see Origin groups.
- Add other origins if needed.
Click Create.

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.

If you have not created origin groups before, connect to the provider first:
```
yc cdn provider activate --type gcore
```
View a description of the CLI command to create an origin group:
```
yc cdn origin-group create --help
```

Create an origin group in the default folder:

yc cdn origin-group create --name <origin_group_name> \
  --origin source=<origin_IP_address_or_domain_name>,enabled=true \
  --origin source=<origin_IP_address_or_domain_name>,enabled=true,backup=true

Where --origin is the origin specification:

source: Origin IP address or domain name.
enabled: Origin enabled flag.
backup: Flag marking the origin as a backup. For more information about priorities, see Origin groups.

Result:

id: "89018"
folder_id: b1g86q4m5vej********
name: test-group
use_next: true
origins:
- id: "559295"
  origin_group_id: "89018"
  source: www.example2.com
  enabled: true
  backup: true
- id: "559294"
  origin_group_id: "89018"
  source: www.example1.com
  enabled: true

For more information about the yc cdn origin-group create command, see the CLI reference.

Make sure to activate the CDN provider before creating an origin group. You can activate it in the management console or using this CLI command:

yc cdn provider activate \
  --folder-id <folder_ID> \
  --type gcore

Where:

--folder-id: ID of the folder in which you want to activate the CDN provider.
--type: Provider type; the only possible value is gcore.

Terraform allows you to quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. Configuration files store the infrastructure description in the HashiCorp Configuration Language (HCL). Terraform and its providers are distributed under the Business Source License.

For more information about the provider resources, see the documentation on the Terraform website or the mirror.

If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

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

Describe the parameters of the yandex_cdn_origin_group resource in the configuration file.

Here is an example of the configuration file structure:
```
resource "yandex_cdn_origin_group" "my_group" {
  name = "<origin_group_name>"
  use_next = true
  origin {
   source = "<IP_address_or_domain_name_of_origin_1>"
  }
  origin {
   source = "<IP_address_or_domain_name_of_origin_2>"
  }
  origin {
   source = "<IP_address_or_domain_name_of_origin_3>"
   backup = false
  }
}
```
Where:
- name: Origin group name.
- use_next: Indicates whether to use the next origin on the list.
- origin: Origin specification:
  - source: Origin IP address or domain name.
  - enabled: Origin enabled flag.
  - backup: Flag marking the origin as a backup. For more information about priorities, see Origin groups.
For more information about the resources that you can create using Terraform, see the provider documentation.
Create resources:
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.
Terraform will create all the required resources. You can check the new CDN resource using the management console or this CLI command:
```
yc cdn origin-group list
```

If you have not created any origin groups before, connect to the CDN provider. To do this, use the activate REST API method for the Provider resource or the ProviderService/Activate gRPC API call.

Use the create REST API method for the OriginGroup resource or the OriginGroupService/Create gRPC API call.
