How to use a custom template with container ?

[Whax]

Hello,

I'm trying to use a custom template for my container using the following :

resource "proxmox_virtual_environment_file" "debian12_custom" {
  content_type = "vztmpl"
  datastore_id = "local-btrfs"
  node_name  = var.node 

  source_file {
    path = "cache/debian-12-custom.tar.zst"
  }
}

resource "proxmox_virtual_environment_container" "Headscale" { 
 ...
  operating_system {
    template_file_id = proxmox_virtual_environment_file.debian12_custom.id
    type = "debian"
  }
  ...
}

But i'm getting the following error :

proxmox_virtual_environment_file.debian12_custom: Creating...
╷
│ Error: open cache/debian-12-custom.tar.zst: no such file or directory
│
│   with proxmox_virtual_environment_file.debian12_kraft,
│   on main.tf line 60, in resource "proxmox_virtual_environment_file" "debian12_custom":
│   60: resource "proxmox_virtual_environment_file" "debian12_custom" {
│

What I'm missing ?

Thanks for the help !

Okay I found the solution reading again
https://github.com/bpg/terraform-provider-proxmox/blob/main/docs/resources/virtual_environment_file.md

I was thinking the path of source_file for my template could be used as my local path but it seems to only work for downloading image

The solution was to set the ftemplate_file_id like that :

  operating_system {
    template_file_id = "local-btrfs:vztmpl/debian-12-custom.tar.zst" 
    type = "debian"
  }
