qveensi yesterday @qveensi have you tried the ccm from Syself? https://github.com/syself/hetzner-cloud-controller-manager

I picked up their solution, but I still did not find how to add iron nodes to the cluster, ccm still looks for nodes in hcloud, not robots, and there are no instructions on how to add nodes.

i used chart syself/ccm-hetzner with all the necessary keys in secret, including the login/password for robots.

logs from ccm:

W0907 09:24:46.685193       1 topologycache.go:199] Can't get CPU or zone information for k8s-node-2 node

and after append bare-metal nodes in my cluster, cluster-autoscaler not working yes:

E0907 10:19:22.011063       1 static_autoscaler.go:354] Failed to get node infos for groups: failed to check if server  exists error: failed to get servers for node k8s-node-2 error: server not found

maybe i can somehow set it to ignore bare-metal nodes?

I setup cluster over kubeadm with official docs: https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/

Here are the general caph docs: https://github.com/syself/cluster-api-provider-hetzner/tree/main/docs

You need to create a HetznerBareMetalHost via yaml, so that you define which bare metal machines will be integrated into your cluster.

Docs: https://github.com/syself/cluster-api-provider-hetzner/blob/main/docs/reference/hetzner-bare-metal-host.md
