How can I use x86 and arm in one worker_nodepool?

[ocelik94]

Hey,

I want to use a x86 and a arm worker but I do not understand how I can manage to do that.

my current configuration:

module "kubernetes" {
  source  = "hcloud-k8s/kubernetes/hcloud"
  version = "0.14.1"

  cluster_name = "k8s"
  hcloud_token = var.hcloud_token

  cluster_kubeconfig_path  = "kubeconfig"
  cluster_talosconfig_path = "talosconfig"

  cert_manager_enabled  = true
  ingress_nginx_enabled = true
  longhorn_enabled = true

  control_plane_nodepools = [
    { name = "control", type = "cax11", location = "fsn1", count = 1 }
  ]
  worker_nodepools = [
    { name = "worker", type = "cax21", location = "fsn1", count = 1 },
    { name = "workerx86", type = "cx22", location = "fsn1", count = 1 }
  ]
}

I am getting following error if I try to apply that:

│ Error: ip range overlaps with existing subnetwork or route (invalid_input, 8c5...): [] │ │ with module.kubernetes.hcloud_network_subnet.worker["workerx86"], │ on .terraform/modules/kubernetes/network.tf line 93, in resource "hcloud_network_subnet" "worker": │ 93: resource "hcloud_network_subnet" "worker" {

Have you applied a different configuration with other node pools before this one, which was unsuccessful and left the subnet behind as a leftover? There's also a chance that a subnet or route was added manually, which overlaps with the workerx86 subnet (10.0.65.128/25).

However, your current configuration is in good shape. I just tested it and everything's running smoothly.
