Terraform Quick Start
All resources created with Terraform are paid for according to the payment model. Charging for the resource begins after resource creation.
The cost of resources created with Terraform is not different from the cost of resources created with control panel.
Install Terraform
-
Download the Terraform distribution for your operating system from HashiCorp website or with the mirror. We recommend downloading the Terraform 1.9 version.
-
If you downloaded the Terraform distribution from a mirror, export to an environment variable
PATH
the way to it:export PATH=$PATH:<path>
Specify
<path>
— path to the Terraform binary file. -
Install Terraform. For Linux and macOS, use the instructions Install Terraform HashiCorp documentation.
Create a service user
To work with examples you need to create a service user with two roles:
- Account Administrator — The role is needed to initialize the Selectel provider and create resources;
- and User Administrator — to create additional users and differentiate access in projects.
- In the control panel go to Identity & Access Management → User management.
- Click Add user.
- Select the user type Service user.
- Enter a user name. This will be used for authorization.
- Enter a password for the user or generate one. Once a user has been created, you cannot view the password — you can only generate a new one. The password must be no shorter than eight characters and contain Latin letters of different cases and digits.
- Select the user role of Account Administrator.
- Click Add role and select the User Administrator role.
- Click Add user. It will be added to the list on the tab Service users. The account will be active immediately.
Configure providers
If the version of the Selectel Terraform provider you are using is lower than 6.0.0, you can upgrade. See the instructions for details Upgrading Terraform Selectel Provider to version 6.0.0.0 on the Terraform Registry.
-
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 exampleru-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.
