Hetzner Server Types

We are hosting our complete setup on Hetzner infrastructure. The setup makes use of the following types of Objects:

via Hetzner Console - Cloud Server (for light workloads like bastion, control-plane, etcd, etc.) - Load Balancers - Networks

via Hetzner Robot - Bare Metal Servers (for heavy workloads, propably mostly for workers)

Order a new server

via Hetzner Console

Furthermore we would reccommend the following settings:

  • Server location: Falkenstein
  • OS Image: Ubuntu 24.04 currently
  • Type: Hetzner has two main lines of servers. Which are CPX for AMD64 and CAX for ARM64. The Bastion host and the k3s nodes for the Local-Rancher Cluster are running on ARM64. Everything else should usually run on AMD64 and therefore the CPX Servers should be used.
  • Networking: The Bastion-Host has public IPs. Everything else should only use the existing private network.
  • SSH-Keys: You may add a SSH key. Does not make a difference later, since we will disable root-login.
  • Volumes: Currently not used
  • Firewalls: Currently not used
  • Backups: Configure according to your preferences
  • Placement Groups: Use the placement group for the currenly used cluster.
  • Labels: Currently not used
  • Cloud Config: see Cloud Init
  • Name: Please check the currently used naming conventions before setting a new server name.
