Disable the default load balancer about terraform-hcloud-kube-hetzner HOT 7 CLOSED

The two loadbalancers serve a different purpose:

• The k3s loadbalancer is the loadbalancer that's used for the control-plane, so you, as an admin can talk to k3s
• The ct-k3s-traefik loadbalancer is the loadbalancer that's used for ingress, so the enduser can visit any website you make available via k3s

You could disable the k3s loadbalancer by setting this in your kube.tf:

  use_control_plane_lb = false

Hi,
sorry for the late response.
First of all, the k3s load balancer is the one from traefik, which i manualy added via the values of the traefik install under the annotations. The ct-k3s-traefik load balancer is getting created by the library with the load_balancer_type. The problem is that the load balancer created by the library does not have any services and is not attached to any servers. And so it doesn't serve any purpose exept it wastes money.
So I don't know why there is a mandatory load balancer created for nothing, because even if i disable the manual load balancer i added, the load balancer created by the library still isn't doing anything. Maybe it isn't working because I currently only have one control plane node but i don't know.

Thank you for your time and help.

Does this answer your question?

Ah, I misunderstood the problem here.

Interesting. Can you see if:

1- The load-balancer ct-k3s-traefik has any labels attached to them?
2- Is your cluster_name by any chance ct-k3s ?

If your loadbalancer has the labels provisioner, engine and cluster attached, and no other labels, you could try changing the names to match

...
traefik_values = <<EOT
...
  annotations:
    "load-balancer.hetzner.cloud/name": "ct-k3s-traefik"

This should make the cluster think it needs to use a loadbalancer with that name, instead of trying to provision one with the k3s name.

It seems that a loadbalancer for ingresses is always made at current, when your ingress is not set to "none".
I think that setting enable_klipper_metal_lb = "true" should also disable that loadbalancer. YMMV, I'm an nginx user myself 🤣

@InfernoCraft Your problem comes from editing the traefik helm value manually, try using the same name for the lb as the one you see created.

@InfernoCraft Your github access token may have leaked, in the above kube.tf, I deleted it, but if is was really the original one, better regenerated it.

Closing for now, as this is just a config issue.
