Show HN: 10x Kubernetes Cluster on Hetzner Cloud

3 jceb81 0 6/27/2025, 8:23:08 AM github.com ↗

I created this terraform/tofu module that provisions a k8s/k3s cluster on Hetzner's cloud. If you compare the price to popular hyperscalers you get 10x the value for your buck.

Quick overview of the most important features: - hosts are managed in node pools, like you'd do on AKS, etc - the cluster configuration has been hardened according to k3s hardening guide (https://docs.k3s.io/security/hardening-guide) - the cluster is private by default and can not be accessed from the internet - you decide what to expose - nodes are auto-installing security updates - Kubernetes updates are managed from within the cluster via upgrade plans - an Ansible inventory is generated so commands can be easily invoked on all systems / selected node pools simultaneously - just the bare minimum of charts (hcloud-ccm, hcloud-csi, cilium and system-upgrade-controller) is installed so you can select what is deployed as ingress controller, gitops solution, etc - extensive documentation is provided to configure, maintain and troubleshoot the cluster

Would love to hear your feedback. A number of organizations are already using the module in production.
