Terraform Provider seems to ignore user-data

[CND-MW]

Description

I am trying to inject commands for cloud-init via ‘user-data’ into a cubeserver. I have used the commands as heredoc and as base64 encoded string. Unfortunately, the content is not executed in either case. It is independent of the image used (I have tried debian:11, debian:12 and ubuntu:24.04). If you run the script via the data centre, it works perfectly. Here is the configuration (the script is just an example without much sense):

resource "ionoscloud_cube_server" "server" {
  datacenter_id     = ionoscloud_datacenter.dc.id
  name              = "Server"
  availability_zone = "AUTO"
  template_uuid     = data.ionoscloud_template.template.id
  image_name        = data.ionoscloud_image.image.id
  ssh_key_path      = [ "/root/.ssh/id_ionos_ecdsa.pub" ]
  volume {
    name            = "Vol-Server"
    disk_type       = "DAS"
    user_data       = "IyEvYmluL2Jhc2gKZWNobyAiSGVsbG8gd29ybGQhIiA+L3Vzci9sb2NhbC9zcmMvbW90ZApjaG1vZCA2NDQgL3Vzci9sb2NhbC9zcmMvbW90ZAo="
  }
  nic {
    lan             = ionoscloud_lan.wan.id
    name            = "Nic WAN"
    dhcp            = true
    ips             = [ "${var.public-ip}" ]
    firewall_active = false
  }
}

Expected behavior

a file, e.g. in /usr/local/src

Environment

Terraform version:

Terraform v1.9.7
on linux_amd64

Provider version:

6.5.7

OS:

We will fix this. Meanwhile, if you need this urgently, you can create a ionoscloud_server with type CUBE

resource "ionoscloud_server" "server" {
  datacenter_id     = ionoscloud_datacenter.dc.id
  name              = "Server"
  type                = "CUBE"
  availability_zone = "AUTO"
  template_uuid     = data.ionoscloud_template.template.id
  image_name        = data.ionoscloud_image.image.id
  ssh_key_path      = [ "/root/.ssh/id_ionos_ecdsa.pub" ]
  volume {
    name            = "Vol-Server"
    disk_type       = "DAS"
    user_data       = "IyEvYmluL2Jhc2gKZWNobyAiSGVsbG8gd29ybGQhIiA+L3Vzci9sb2NhbC9zcmMvbW90ZApjaG1vZCA2NDQgL3Vzci9sb2NhbC9zcmMvbW90ZAo="
  }
  nic {
    lan             = ionoscloud_lan.wan.id
    name            = "Nic WAN"
    dhcp            = true
    ips             = [ "${var.public-ip}" ]
    firewall_active = false
  }
}

Perfect. That's the solution. Many thanks for the quick help!
