How to use Terraform (2023)

Last updated on May 27, 2022

objective

OpenStack is an open source cloud operating system for building and managing public and private cloud computing platforms. The OpenStack software components form the basis of the OVHcloud public cloud infrastructure.

The open source tool Terraform was developed to facilitate the creation of complex cloud infrastructures. It allows abstracting the properties of your infrastructure into text files that can be used as a basis for deploying your infrastructure.

As an example, this video shows how you can easily scale the number of instances while keeping your existing infrastructure by changing just one line of code:

This guide explains how to use Terraform with the public cloud using practical examples.

requirements

Configure user access to Horizon
Prepare an environment to use the OpenStack API
Setting OpenStack environment variables
Your OVHcloud API identifiers and authorization keys
An SSH key
Terraform OpenStack provider
The OVHcloud Terraform provider

This tutorial is compatible with Terraform version 0.14.0 and higher.

instructions

Creating the Terraform environment

After Terraform installation, create a directory for all text files describing your infrastructure:

mkdir test_terraform && cd test_terraform

You can now create a terraform environment with the following command. This allows you to create and manage the development of your infrastructure.

Terraform workspace new test_terraform

create resources

Creating a Provider

In Terraform, you specify "Provider" for your cloud environment. A "vendor" (like OVHcloud) hosts your OpenStack infrastructure resources.

Create a file namedAnbieter.tfwith the following content:

# Define vendors and set versionsTerraform {required_version = ">= 0.14.0" # Considers Terraform versions from 0.14.0 required_vendors { Openstack = { Those = "terraform-provider-openstack/openstack" execution = "~> 1.42.0" } oh = { Those = "ovh/ovh" execution = ">= 0.13.0" } }}# Configure the OpenStack provider hosted by OVHcloudOfferer "open stack" { auth_url = "https://auth.cloud.ovh.net/v3/" # Authentication URL domain name = "Originally" # Domain name - Always on "Default" for OVHcloud alias = "ohh" # An alias}Offerer "ohh" { alias = "ohh" end point = "ovh-eu" application key = "<your_access key>" application secret = "<your_application secret>" Consumer_key = "<your_consumer_key>"}

If you don't want to define your secrets in the Terraform configuration file, you can also define them in environment variables:

$ Export OVH_ENDPOINT=ovh-eu$ Export OVH_APPLICATION_KEY=Your_key_application_OVH(or_AK)$ Export OVH_APPLICATION_SECRET=Your_secret_application_key_OVH(or_AS)$ Export OVH_CONSUMER_KEY=your_token(or_CK)

The "alias" is a unique identifier for a provider. For example, if you have two OpenStack providers with different credentials, you need to specify each provider in the resource.

You must nowCreate a new OpenStack user, thenGenerate the OpenRC filewith any credentials you want to export as environment variables.

Load this file and then enter the password for the previously created user:

$ Thoseopenrc.shPlease enter your OpenStack password:

You now need to initialize your workspace to download the provider plugins:

Terraform-Init

Create an instance

In Terraform, a "resource" is a component of your infrastructure. This can be an instance, a storage block provided by the OpenStack provider, or a network provided by the OVHcloud provider.

To create an instance you need at least:

An instance name
A picture
a taste
An SSH key

As an example, let's create a simple instanceDebian 10with the tastep1-2, and import an SSH key. Add the following lines to a file namedsimple_instance.tf:

# Create an SSH key pair resourceResource "openstack_compute_keypair_v2" "test_keypair" { Offerer = Openstack.oh # provider name declared in provider.tf Name = "test_keypair" # Name of SSH key to use for creation public key = file("~/.ssh/id_rsa.pub") # Path to your previously generated SSH key}# Create the instanceResource "openstack_compute_instance_v2" "test_terraform_instance" { Name = "terraform_instance" # instance name Offerer = Openstack.oh # provider name image name = "Debian 10" # image name flavor name = "s1-2" # Instance type name # Name der openstack_compute_keypair_v2-Ressource namens keypair_test key pair = openstack_compute_keypair_v2.test_keypair.Name network { Name = "ext-net" # Adds the network component to reach your instance }}

To see what is being added/created/deleted in your infrastructure you can run:

Terraform-Plan

You can enter the following command to import your SSH key and create your first instance:

apply terraform

The output should look like this:

$ terraform applyopenstack_compute_keypair_v2.test_keypair: Updating state... [id=test_keypair] Terraform used the selected providers to generate the following execution plan. Resource actions are denoted by the following icons: + createTerraform performs the following actions: # creates openstack_compute_instance_v2.test_terraform_instance + resource "openstack_compute_instance_v2" "test_terraform_instance" { + access_ip_v4 = (known after apply) + access_ip_v6 = (known after apply) + all_metadata = (known after apply) + all_tags = (known after apply) + availability_zone = (known after apply) + flavor_id = (known after apply) + flavor_name = "s1-2" + force_delete = false + id = (known after apply ) + image_id = (known after apply) + image_name = "Debian 10" + key_pair = "test_keypair" + name = "terraform_instance" + power_state = "active" + region = (known after apply) + security_groups = (known after apply) + stop_before_destroy = false + network { + access_network = false + fixed_ip_v4 = (known after apply) + fixed_ip_v6 = (known after apply) + floating_ip = (known after apply) + mac = (known after apply) + name = "Ext-Net " + port = (known after apply) + uuid = (known after apply) } }Plan: 1 to add, 0 to change, 0 to destroy. Do you want to perform these actions in the test_terraform workspace? Terraform performs the actions described above. Only "Yes" will be accepted for approval. Enter a value: yesopenstack_compute_instance_v2.test_terraform_instance: Creating...openstack_compute_instance_v2.test_terraform_instance: Still creating...

Resources: 1 added, 0 changed, 0 destroyed.

Sign up for the nowOVHcloud Customer Center, go toPublic cloudsection and clickinstances. As you can see, your compute instance is created with the name "terraform_instance".

Note that creating a second, identical instance withapply terraformwill not work.
Terraform only applies changes when it detects a difference in your configuration files or a new file.

Creating multiple instances

In this section, we will create an Ubuntu instance of the "s1-2" flavor in three different regions.

You can find all region names by checking this OVHcloud API endpoint:

RECEIVEcloud/project/{serviceName}/region

For this example we will use the following OVHcloud regions:

(Video) Beginners Tutorial to Terraform with AWS

GRA11
SBG5
BHS5

You can create three resources named openstack_compute_instance_v2 and change the region parameter for each one. However, it can become difficult to manage files with a large number of identical resources.

A better method is to use the resource metaparameter called "count". This allows you to instruct Terraform to create the same resource multiple times.

To do this, we create a file calledmultiple_instance.tf. In it, we first define a variable to hold the three regions, and then add an instance creation counter:

# Create a region variable containing the list of OVHcloud regions# It is used to iterate over different regions# start an instance on each of them. Variable "Region" { Typ = list Originally = ["GRA11", "SBG5", "BHS5"] }# Create an SSH key pair Resource "openstack_compute_keypair_v2" "test_keypair_all" { counting = Long(war.Region) Offerer = Openstack.oh # Specify provider name Name = "test_keypair_all" # SSH key name public key = file("~/.ssh/id_rsa.pub") # Your SSH key path Region = Element(war.Region, counting.Index) } # Create a resource in each region that is an OpenStack instance Resource "openstack_compute_instance_v2" "instances_in_all_regions" { # How often the resource is created # defined by the length of the list named region counting = Long(war.Region) Offerer = Openstack.oh # provider name Name = "terraform_instances" # instance name flavor name = "s1-2" # instance flavor image name = "Debian 10" # image name # element is a function that accesses the element at position # count.index of list var.region. It allows to iterate between regions Region = Element(war.Region, counting.Index) # Accesses the name of the openstack_compute_keypair_v2 resource variable named test_keypair key pair = Element(openstack_compute_keypair_v2.test_keypair_all.*.Name, counting.Index) network { Name = "ext-net" # Adds the public network to your instance } }

Review the changes you need to make to your infrastructure with the following command:

Terraform-Plan

Apply your changes with the following command:

apply terraform

Terraform can create multiple instances using this method, but you can also use it to modify your current infrastructure.

Modifying an instance

In this example, we'll add a new storage volume to our first instance. Open and edit the file with the namesimple_instance.tf, then add the following lines:

# Create a resource for storageResource "openstack_blockstorage_volume_v2" "volume_to_add" { Name = "simple_volume" # Volume-Name size = 10 # Volume size in GB Offerer = Openstack.oh # provider name}# Attach the previously created volume to the instanceResource "openstack_compute_volume_attach_v2" "appropriate" { # ID of openstack_compute_instance_v2 resource named test_terraform_instance instance_id = openstack_compute_instance_v2.test_terraform_instance.I would # ID der Ressource openstack_blockstorage_volume_v2 namens volume_to_add volume_id = openstack_blockstorage_volume_v2.volume_to_add.I would}

Review the changes you need to make to your infrastructure with the following command:

Terraform-Plan

Apply your changes with the following command:

apply terraform

Creating an instance on the OVHcloud network (vRack)

The Terraform OVHcloud plugin can manage private networks, private subnets, public cloud users and vRack attachments. In this part we will focus on network creation.

Create a filecreate_private_network_instance.tfand enter the following:

Variable "service name" { Originally = "OS_PROJECT_ID" # Replace with your service name / OS_PROJECT_ID value}Variable "Project_ID" { Originally = "OS_TENANT_ID" # Replace OS_TENANT_ID with your project tenant ID}Variable "Region" { Originally = "GRA11" # Replace with your region, for example with the OS_REGION_NAME environment variable}# Map cloud project to vRack Resource "ovh_vrack_cloudproject" "vcp" { service name = war.service name Project_ID = war.Project_ID} # Create a private network Resource "ovh_cloud_project_network_private" "Network" { service name = war.service name Name = "private network" # network name The region = [war.Region] Offerer = oh.oh # provider name vlan_id = 168 # VLAN ID for vRack depends on = [ovh_vrack_cloudproject.vcp] # Depends on how the vRack is mapped to the cloud project } # Create a subnet with the private network created earlier Resource "ovh_cloud_project_network_private_subnet" "subnet" { service name = war.service name # ID of ovh_cloud_network_private resource named network Network ID = ovh_cloud_project_network_private.network.I would beginning = "192.168.168.100" # First IP of the subnet End = "192.168.168.200" # Last IP of the subnet network = "192.168.168.0/24" # Subnet IP address location DHCP = Is correct # Enable DHCP Region = war.Region Offerer = oh.oh # provider name no_gateway = Is correct # No default gateway } # Create an instance with 2 network interfaces Resource "openstack_compute_instance_v2" "proxy_instance" { Offerer = Openstack.oh # provider name Name = "proxy_instance" # instance name image name = "Debian 10" # image name flavor name = "s1-2" # flavor name # Name der openstack_compute_keypair_v2-Ressource namens keypair_test key pair = openstack_compute_keypair_v2.test_keypair.Name # Add public and private network network { Name = "ext-net" } network { Name = ovh_cloud_project_network_private.network.Name } }

This instance creation is linked to theopenstack_compute_keypair_v2.test_keypairResource you created earlier in this guide.

A new instance with a public and a private interface appears in your public cloud project.

Creating an infrastructure for a website

In this example we will create a basic website infrastructure using Terraform and the OVHcloud private network. The components created are:

a private network
a subnet
two instances, each with two network interfaces: the first public and the second private
an instance with a private interface and two additional disks

Create a public cloud project

You can also create an OVHcloud project directly as code from Terraform.

However, two conditions apply:

You must have at least 3 public cloud projects (note that there is a default limit of 3 projects. To increase this limit, please submit a request to our support teams)
You must have created a public cloud project in the last 3 months.

If any of these business rules are not met, you will receive the following error message:"Permission issues found: ChallengePaymentMethod".
In this case, the only solution is to use theOVHcloud Customer Centerto create a project.
You will then be asked to confirm that you are in fact the owner of the funds used on your account (this challenge depends on the funds and other parameters).

Please understand these rules and additional human steps have been introduced as extra security for customers who may have disclosed their OVHcloud credentials.
We will try to further improve these rules in the future to facilitate infra-as-code scenarios like this public cloud project as code scenario.

Create a file namedProjekt.tfand enter the following lines:

Data "ovh_order_cart" "Car" { ovh_subsidiary = "fr" designation = "Use the French OVH shopping cart by default"}Data "ovh_order_cart_product_plan" "Clouds" { cart_id = Data.ovh_order_cart.Car.I would price_capacity = "renew" Product = "Clouds" Plancode = "project.2018"}Resource "ovh_cloud_project" "Clouds" { ovh_subsidiary = Data.ovh_order_cart.Car.ovh_subsidiary designation = war.project description means of payment = "Loyalty" the plan { duration = Data.ovh_order_cart_product_plan.Clouds.selected_price.0.duration Plancode = Data.ovh_order_cart_product_plan.Clouds.Plancode pricing_mode = Data.ovh_order_cart_product_plan.Clouds.selected_price.0.pricing_mode }}
