hcloud-controller-manager deletes foreign Loadbalancer services and targets

[ol-iver]

Dear maintainers,

apparently deletes services and target from LoadBalancer which are created manually (or by other functions) during reconciliation. That's a bit unfortunate because you cannot use the Loadbalancer for anything else than Kubernetes services.

I would expect that controller-manager labels services and targets under its control and performs change/delete operations on those objects only.

I'm running docker.io/hetznercloud/hcloud-cloud-controller-manager:v1.9.1 image.

This is an excerpt of controller-manager logs. The services using ports 80, 443 and 853 are created by a service of type LoadBalancer with these annotations

  annotations:
    load-balancer.hetzner.cloud/disable-private-ingress: "true"
    load-balancer.hetzner.cloud/name: xyz-lb

The service using port 6443 is created by terraform.
