Create a public IP address

We recommend create resources in order. If you create all the resources that are described in the configuration file The Terraform creates resources regardless of the order in which they are listed in the file.

Optional: configure your ISPs.
Create a public IP address.

Configuration files⁠

Example file for configuring providers

terraform {
  required_providers {
    selectel  = {
      source  = "selectel/selectel"
      version = "6.0.0"
    }
    openstack = {
      source  = "terraform-provider-openstack/openstack"
      version = "2.1.0"
    }
  }
}

provider "selectel" {
  domain_name = "123456"
  username    = "user"
  password    = "password"
  auth_region = "pool"
  auth_url    = "https://cloud.api.selcloud.ru/identity/v3/"
}

resource "selectel_vpc_project_v2" "project_1" {
  name = "project"
}

resource "selectel_iam_serviceuser_v1" "serviceuser_1" {
  name         = "username"
  password     = "password"
  role {
    role_name  = "member"
    scope      = "project"
    project_id = selectel_vpc_project_v2.project_1.id 
  }
}

provider "openstack" {
  auth_url    = "https://cloud.api.selcloud.ru/identity/v3"
  domain_name = "123456"
  tenant_id   = selectel_vpc_project_v2.project_1.id
  user_name   = selectel_iam_serviceuser_v1.serviceuser_1.name
  password    = selectel_iam_serviceuser_v1.serviceuser_1.password
  region      = "ru-9"
}

Example file for creating a public IP address

resource "openstack_networking_floatingip_v2" "floatingip_1" {
  pool = "external-network"
}

optional: configure providers⁠

If you're set up the ISPs Selectel and OpenStack, skip this step.

Make sure that in the control panel you created a service user with the Account Administrator and User Administrator roles.
Create a directory to store the configuration files and a separate file with the extension .tf to configure the ISPs.
Add Selectel and OpenStack providers to the file to configure the providers:
```
terraform {
  required_providers {
    selectel  = {
      source  = "selectel/selectel"
      version = "6.0.0"
    }
    openstack = {
      source  = "terraform-provider-openstack/openstack"
      version = "2.1.0"
    }
  }
}
```
Here version — provider versions. The current version can be found in the Selectel documentation (in the Terraform Registry and GitHub) and OpenStack (in Terraform Registry and GitHub).

Read more about products, services and services that can be managed with providers in the instructions Selectel and OpenStack providers.
Initialize the Selectel provider:
```
provider "selectel" {
  domain_name = "123456"
  username    = "user"
  password    = "password"
  auth_region = "pool"
  auth_url    = "https://cloud.api.selcloud.ru/identity/v3/"
}
```
Here:
- domain_name — Selectel account number. You can look in control panels in the upper right-hand corner;
- username — name service user with the Account Administrator and User Administrator roles. You can look in control panels: section Identity & Access Management → User management → tab Service users (the section is only available to the Account Owner and User Administrator);
- password — service user password. You can view it when creating a user or change to a new one.
Create a project:
```
resource "selectel_vpc_project_v2" "project_1" {
  name = "project"
}
```
Check out the detailed description of the resource selectel_vpc_project_v2.
Create a service user to access the project and assign the Project Administrator role to it:
```
resource "selectel_iam_serviceuser_v1" "serviceuser_1" {
  name         = "username"
  password     = "password"
  role {
    role_name  = "member"
    scope      = "project"
    project_id = selectel_vpc_project_v2.project_1.id 
  }
}
```
Here:
- username — username;
- password — user password. The password must be no shorter than eight characters and contain Latin letters of different cases and digits;
- project_id — Project ID. You can look in control panels: section Cloud platform → open the project menu (name of the current project) → in the line of the desired project, click .
Check out the detailed description of the resource selectel_iam_serviceuser_v1.

Initialize the OpenStack provider:

provider "openstack" {
  auth_url    = "https://cloud.api.selcloud.ru/identity/v3"
  domain_name = "123456"
  tenant_id   = selectel_vpc_project_v2.project_1.id
  user_name   = selectel_iam_serviceuser_v1.serviceuser_1.name
  password    = selectel_iam_serviceuser_v1.serviceuser_1.password
  region      = "ru-9"
}

Here:

domain_name — Selectel account number. You can look in control panels in the upper right-hand corner;
region — pool for example ru-9. All resources will be created in this pool. The list of available pools can be found in the instructions Availability matrices.

If at the same time you are setting up your providers resource creation then for OpenStack resources add the argument depends_on. For example, for the openstack_networking_network_v2 resource:

resource "openstack_networking_network_v2" "network_1" {
  name           = "private-network"
  admin_state_up = "true"

  depends_on = [
    selectel_vpc_project_v2.project_1,
    selectel_iam_serviceuser_v1.serviceuser_1
  ]
}

Optional: if you want to use a mirror, create a separate Terraform CLI configuration file and add a block to it:

provider_installation {
  network_mirror {
    url = "https://tf-proxy.selectel.ru/mirror/v1/"
    include = ["registry.terraform.io/*/*"]
  }
  direct {
    exclude = ["registry.terraform.io/*/*"]
  }
}

Read more about mirror settings in the manual CLI Configuration File HashiCorp documentation.

Open the CLI.
Initialize the Terraform configuration in the directory:
```
terraform init
```
Check that the configuration files have been compiled without errors:
```
terraform validate
```
Format the configuration files:
```
terraform fmt
```
Check the resources that will be created:
```
terraform plan
```
Apply the changes and create the resources:
```
terraform apply
```
Confirm creation — enter yes and press Enter. The created resources are displayed in the control panel.
If there were insufficient quotas to create resources, increase quotas.
