How to find a STACKIT server boot image ID?

When provisioning a server in STACKIT with Terraform, we need a boot volume and a disk image for that volume. Several curated images are available from STACKIT directly, and there is also a way to add own images.

When referencing an image in Terraform, we must give the image ID, which is a GUID. The STACKIT Terraform Provider documentation for example has the following snipped for server creation.

resource "stackit_server" "user-data-from-file" {
  project_id   = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  boot_volume = {
    size        = 64
    source_type = "image"
    source_id   = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  }
  name         = "example-server"
  machine_type = "g2i.1"
  keypair_name = stackit_key_pair.keypair.name
  user_data    = file("${path.module}/cloud-init.yaml")
}

resource "stackit_server" "user-data-from-file" {
  project_id   = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  boot_volume = {
    size        = 64
    source_type = "image"
    source_id   = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  }
  name         = "example-server"
  machine_type = "g2i.1"
  keypair_name = stackit_key_pair.keypair.name
  user_data    = file("${path.module}/cloud-init.yaml")
}

The question is: how to get the value of boot_volume.source_id?

How to get a boot volume source_id?

The best way I found so far is to use the STACKIT CLI. With the STACKIT CLI we can list all available images with the following command

stackit image list --project-id xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

stackit image list --project-id xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Full list of STACKIT server images

The resulting list of images is (as of 27.10.2025):
