</details>

## 1. Optional: configure providers \{#configure-providers}

If you have already configured Selectel and OpenStack providers, skip this step.

<ConfigureProviders />

## 2. Add a public SSH key \{#add-public-ssh-key}

<AddPublicSsh />

## 3. Create a private network and subnet \{#create-networks}

<CreateNetworks />

## 4. Create a cloud router connected to the internet \{#create-router}

<CreateRouter />

## 5. Create ports for cloud servers \{#create-ports}

```hcl
resource "openstack_networking_port_v2" "port" {
  name       = "port"
  count      = 3
  network_id = openstack_networking_network_v2.network2.id

  fixed_ip {
    subnet_id = openstack_networking_subnet_v2.subnet_2.id
  }
}

```

Here `count` is the number of ports.

See the detailed description of the [openstack\_networking\_port\_v2](/terraform/openstack-provider-reference/networking-neutron/resources/openstack_networking_port_v2/) resource.

## 6. Get an image \{#get-image}

<GetImage />

## 7. Create cloud servers \{#create-servers}

```hcl
resource "openstack_compute_instance_v2" "server" {
  name              = "server"
  count             = 3
  image_id          = data.openstack_images_image_v2.ubuntu.id
  flavor_id         = "1312"
  key_pair          = selectel_vpc_keypair_v2.keypair_1.name
  availability_zone = "ru-9a"

  network {
    port = openstack_networking_port_v2.port[count.index].id
  }

  lifecycle {
    ignore_changes = [image_id]
  }

  vendor_options {
    ignore_resize_confirmation = true
  }
}
```

Where:

* `count` is the number of servers;
* `flavor_id` — flavor ID. For example, `1312` — ID of the fixed-configuration flavor from the Standard line with 1 vCPU, 2048 GB RAM, 16 GB local disk. The list of flavors can be viewed using the `openstack flavor list` command or in the [List of fixed-configuration flavors in all pools](/cloud-servers/create/configurations/#server-flavors-full-list);
* `availability_zone` — [pool segment](/infrastructure/locations/#pool) in which cloud servers will be created, for example `ru-9a`. The list of available pool segments can be viewed in the [Availability Matrix](/infrastructure/availability-matrix/).

See the detailed description of the [openstack\_compute\_instance\_v2](/terraform/openstack-provider-reference/compute-nova/resources/openstack_compute_instance_v2/) resource.

## 8. Create public IP addresses \{#create-public-ips}

```hcl
resource "openstack_networking_floatingip_v2" "floatingip" {
  count = 3
  pool  = "external-network"
}
```

Here `count` is the number of public IP addresses.

See the detailed description of the [openstack\_networking\_floatingip\_v2](/terraform/openstack-provider-reference/networking-neutron/resources/openstack_networking_floatingip_v2/) resource.

## 9. Associate public and private IP addresses of cloud servers \{#associate-ips}

Public IP addresses will be attached to cloud server ports and associated with private IP addresses.

```hcl
resource "openstack_networking_floatingip_associate_v2" "association" {
  count       = 3
  port_id     = openstack_networking_port_v2.port[count.index].id
  floating_ip = openstack_networking_floatingip_v2.floatingip[count.index].address
}
```

Here `count` is the number of public and private IP address associations.

See the detailed description of the [openstack\_networking\_floatingip\_associate\_v2](/terraform/openstack-provider-reference/networking-neutron/resources/openstack_networking_floatingip_associate_v2/) resource.
