hetzner-k3s is a CLI tool written in Crystal that creates production-ready Kubernetes (k3s) clusters on Hetzner Cloud from a single YAML config file. It provisions masters, workers, networking, firewalls, and essential components like the CSI driver and cluster autoscaler in minutes without Terraform or a management cluster.

Use cases

• create a production kubernetes cluster on hetzner cloud
• spin up an ha k3s cluster in minutes
• provision kubernetes without terraform
• set up a cluster autoscaler on hetzner
• deploy a large kubernetes cluster with many worker nodes
• manage k3s cluster config as a yaml file
• reduce kubernetes hosting costs compared to managed k8s

When to choose

• you use Hetzner Cloud and want fast, repeatable k3s cluster provisioning
• you want a simple single-binary tool with one YAML config instead of Terraform/Ansible
• you need HA masters, autoscaling, and CSI/cloud controller installed out of the box
• you want credentials to stay local with no third-party service involved

When to avoid

• you run on AWS, GCP, Azure, or other cloud providers
• you need a managed control plane with SLAs and vendor support
• you already have a Terraform-based infrastructure workflow you must integrate with
• you need Kubernetes distributions with features beyond what k3s provides
