# Basic VM Deployment Example
# =============================================================================
# This is a minimal example for learning the VM module. It shows only the
# required parameters with sensible defaults for everything else.
#
# Use this as a starting point for understanding the module, then refer to
# Triangulum-Prime examples for production-ready configurations.

# Basic VM Module Usage
# =============================================================================

  pve_node = var.proxmox_node  # Which Proxmox node to deploy on
  vm_name  = var.vm_name       # Name of the VM

  # Specify which template to clone from

      datastore_id = "local-lvm"
      size         = 20  # GB
      main_disk    = true
      # Note: file_format, iothread, ssd, discard use optimal defaults
    }

  # === REQUIRED: Network Configuration ===
  # At minimum, configure one network interface

    user = {
      name = var.username
      keys = [var.ssh_public_key]

  # === REQUIRED: EFI Disk (for UEFI boot) ===
  vm_efi_disk = {
    datastore_id = "local-lvm"
    # file_format defaults to "raw"
    # type defaults to "4m"
  }

  # === OPTIONAL OVERRIDES ===
  # These are only shown here for educational purposes.
  # The module already provides these defaults - you DON'T need to specify them!

  # CPU (defaults to 2 cores, "host" type)
  # vm_cpu = {
  #   cores = 2
  #   type  = "host"
  # }

  # Memory (defaults to 2048 MB / 2GB)
  # vm_mem = {
  #   dedicated = 2048
  # }

  # Guest agent (defaults to enabled)
  # vm_agent = {
  #   enabled = true
  # }

  # VM start behavior (defaults: start on deploy, start on boot)
  # vm_start = {
  #   on_deploy = true
  #   on_boot   = true
  # }
