Creating a cloud network

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.

To create a cloud network:

1. See the description of the CLI command for creating a cloud network:

   yc vpc network create --help
   

2. Create a cloud network in the default folder:

   yc vpc network create \
     --name test-network-1 \
     --description "My test network"
   

   The --name and --description flags are optional: you can create a network without any name or description and access it by ID.

   The network naming requirements are as follows:

   • The name must be from 3 to 63 characters long.
   • It may contain lowercase Latin letters, numbers, and hyphens.
   • The first character must be a letter and the last character cannot be a hyphen.

3. Get a list of all cloud networks in the default folder:

   yc vpc network list
   

   Result:

   +----------------------+----------------+
   |          ID          |      NAME      |
   +----------------------+----------------+
   | enpiuvhhd4t8******** | test-network-1 |
   | enplom7a98s1******** | default        |
   +----------------------+----------------+
   

   Get the same list with more details in YAML format:

   yc vpc network list --format yaml
   

   Result:

   - id: enpiuvhhd4t8********
     folder_id: b1g6ci08ma55********
     created_at: "2018-10-23T11:12:51Z"
     name: test-network-1
     description: My first network
   - id: enplom7a98s1********
     folder_id: b1g6ci08ma55********
     created_at: "2018-09-24T08:23:00Z"
     name: default
     description: Auto-created default network
   

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.

1. In the configuration file, describe the parameters of your cloud network:

   • name: Name of the cloud network. The naming requirements are as follows:

     • The name must be from 3 to 63 characters long.
     • It may contain lowercase Latin letters, numbers, and hyphens.
     • The first character must be a letter and the last character cannot be a hyphen.

   • description: Description of the cloud network.

   • labels: Cloud network labels. Specify a key-value pair.

   Here is an example of the configuration file structure:

   resource "yandex_vpc_network" "default" {
     name        = "<network_name>"
     description = "<network_description>"
     labels = {
       tf-label    = "tf-label-value"
       empty-label = ""
     }
   }
   

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

2. Make sure the configuration files are correct.

   1. In the command line, go to the folder where you created the configuration file.

   2. Run a check using this command:

      terraform plan
      

   If the configuration is described correctly, the terminal will display a list of created resources and their parameters. If the configuration contains any errors, Terraform will point them out.

3. Deploy cloud resources.

   1. If the configuration does not contain any errors, run this command:

      terraform apply
      

   2. Confirm creating the resources: type yes in the terminal and press Enter.

      All the resources you need will then be created in the specified folder. You can check the new resources and their settings using the management console or these CLI commands:

      yc vpc network list
      

To create a cloud network, use the create REST API method for the Network resource or the NetworkService/Create gRPC API call, and provide the following in the request:

• ID of the folder the network will reside in, in the folderId parameter.
• Name of the new network in the name parameter. The name must be from 3 to 63 characters long, the last character cannot be a hyphen.
• New network description in the description parameter. The description may be up to 256 characters long.

The name and description parameters are optional: you can create a network without any name or description and access it by ID.

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

1. In the configuration file, describe the parameters of the cloud network to create:

   resource "yandex_vpc_network" "default" {
     name        = "network-1"
     description = "My first network"
   }
   

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

2. Make sure the configuration files are correct.

   1. In the command line, go to the folder where you created the configuration file.

   2. Run a check using this command:

      terraform plan
      

   If the configuration is described correctly, the terminal will display a list of created resources and their parameters. If the configuration contains any errors, Terraform will point them out.

3. Deploy cloud resources.

   1. If the configuration does not contain any errors, run this command:

      terraform apply
      

   2. Confirm creating the resources: type yes in the terminal and press Enter.

      All the resources you need will then be created in the specified folder. You can check the new resources and their settings using the management console or these CLI commands:

      yc vpc network list
