[FEATURE] Create instance with image name and flavor name

[sguyennet]

Description

When I want to create an instance, I have to call the OVHcloud API to get the image ID and the flavor ID.
I would like the provider to do that for me and be able to create an instance using the name of the flavor and the name of the image.

I should at least be able to get the IDs with a Terraform data and not have to call the OVHcloud API

Hey,
there are already data sources for both.

Here's my working used example configuration code:

terraform {
  required_providers {
    ovh = {
      source = "ovh/ovh"
    }
    tls = {
      source = "hashicorp/tls"
    }
  }
}

provider "ovh" {}

locals {
  service_name   = "<public cloud project ID>"
  region         = "WAW1"
  image_name     = "Ubuntu 24.04"
  flavor_name    = "b2-7"
  instance_name  = "my-instance"
  ssh_key_name   = "terraform-key"
  billing_period = "hourly"
}

# Generate an SSH key pair
resource "tls_private_key" "ssh" {
  algorithm = "ED25519"
}

# Look up available images filtered by region and OS type
data "ovh_cloud_project_images" "images" {
  service_name = local.service_name
  region       = local.region
  os_type      = "linux"
}

# Look up available flavors filtered by region and name
data "ovh_cloud_project_flavors" "flavors" {
  service_name = local.service_name
  region       = local.region
  name_filter  = local.flavor_name
}

locals {
  # Find the image matching the desired name
  image = one([
    for img in data.ovh_cloud_project_images.images.images :
    img if img.name == local.image_name
  ])

  # Get the first matching flavor
  flavor = one(data.ovh_cloud_project_flavors.flavors.flavors[*])
}

resource "ovh_cloud_project_instance" "instance" {
  service_name   = local.service_name
  region         = local.region
  billing_period = local.billing_period
  name           = local.instance_name

  boot_from {
    image_id = local.image.id
  }

  flavor {
    flavor_id = local.flavor.id
  }

  ssh_key_create {
    name       = local.ssh_key_name
    public_key = tls_private_key.ssh.public_key_openssh
  }

  network {
    public = true
  }
}

output "instance_id" {
  description = "ID of the created instance"
  value       = ovh_cloud_project_instance.instance.id
}

output "selected_image" {
  description = "The image that was selected"
  value = {
    id   = local.image.id
    name = local.image.name
  }
}

output "selected_flavor" {
  description = "The flavor that was selected"
  value = {
    id   = local.flavor.id
    name = local.flavor.name
  }
}

output "ssh_private_key" {
  description = "Generated SSH private key (save this to connect to the instance)"
  value       = tls_private_key.ssh.private_key_openssh
  sensitive   = true
}

output "ssh_public_key" {
  description = "Generated SSH public key (uploaded to OVH)"
  value       = tls_private_key.ssh.public_key_openssh
}

Cheers
