How to Create a VM in Proxmox with Terraform and Ensure Unique Names in Case of Conflict

Terraform
1

Good afternoon. I have some Terraform code that normally creates the debian-image VM on Proxmox, but when I run it again, it doesn’t create the VM because one with that name already exists. How can I modify the code so that if a VM with that name already exists, it changes the name?

My provider.tf

terraform {
  required_version = ">= 1.6.3"
  required_providers {
    proxmox = {
      version = ">= 2.9.14"
      source  = "telmate/proxmox"
    }
  }
}

provider "proxmox" {
  pm_api_url      = var.pm_api_url
  pm_tls_insecure = true
  pm_api_token_id = "xxxx-xxxx-xxxx"  # Defina apenas uma vez
  pm_api_token_secret = "xxxx-xxxx-xxxx"  # Defina apenas uma vez
}

my variables.tf

variable "pm_user" {
  type        = string
  description = "Username for Authentication"
  default     = "root"
}

variable "pm_api_url" {
  type        = string
  description = "API URL: https://192.168.124.2:8006/api2/json"
  default     = "https://192.168.124.2:8006/api2/json"
}


variable "target_node" {
  type        = string
  description = "The name of the node"
  default     = "terraform"
}

my vm.tf

resource "proxmox_vm_qemu" "debian" {
  name        = "debian-image"
  desc        = "Maquina Debian"
  target_node = var.target_node
  pool        = ""

  clone = "debian-11-cloudinit-template"

  full_clone = false
  scsihw     = "virtio-scsi-single"
  agent      = 1
  balloon    = 1
  cores      = 2
  sockets    = 1
  cpu        = "host"
  memory     = 2048
  network {
    model     = "virtio"
    bridge    = "vmbr0"
    firewall  = false
    link_down = false
  }

  timeouts {
    create = "10m"
    delete = "10m"
  }

}
