Creation of main.tf

Usually main.tf file contains a provider section which signifies which Provider is being utilized.

Required Providers

terraform {
  required_providers {
    proxmox = {
      source  = "Telmate/proxmox"
      version = "2.9.11"
    }
  }
}
...

Using Provider

Makes use of arguments provided by the provider.

provider "proxmox" {
  # Configuration options
  pm_api_url          = "https://10.0.0.5:8006/api2/json"
  pm_api_token_id     = "token-id"
  pm_api_token_secret = "secret-token"
  
  /*
  Enables extra logging https://github.com/Telmate/terraform-provider-proxmox/issues/455#issuecomment-984324159. This can also be found under "Logging" section of provider's documentation https://registry.terraform.io/providers/Telmate/proxmox/latest/docs.
  */
  pm_debug            = true
  pm_log_enable       = true
  pm_log_file         = "terraform-plugin-proxmox.log"
  pm_log_levels = {
    _default    = "debug"
    _capturelog = ""
  }
}

Using Resources

Makes use of arguments provided by provider to add the resources that are required.

resource "proxmox_lxc" "basic" {
  target_node  = "pve-R730"
  hostname     = "Test-tf-container"
  ostemplate   = "local:vztmpl/ubuntu-22.04-standard_22.04-1_amd64.tar.zst"
  password     = "testmonkey"
  unprivileged = true

  // Terraform will crash without rootfs defined
  rootfs {
    storage = "Disk0"
    size    = "8G"
  }

  network {
    name   = "eth0"
    bridge = "vmbr1"
    ip     = "dhcp"
  }
}
