hcloud-k8s

My Kubernetes cluster on Hetzner Cloud. Uses hcloud-k8s/kubernetes/hcloud terraform module which runs Talos Linux (no SSH, API-only, immutable OS).

What's in here

• 1 control plane + 2 workers (cx23, Helsinki)
• Cilium CNI with WireGuard encryption
• cert-manager for TLS
• Traefik ingress
• State stored in Hetzner Object Storage (S3)

Setup

cp terraform.tfvars.example terraform.tfvars
# fill in your hcloud token

cp backend.conf.example backend.conf
# fill in s3 access_key and secret_key

terraform init -backend-config=backend.conf
terraform apply

Kubeconfig gets written to ./kubeconfig after apply.

Scaling to HA

Change control plane count from 1 to 3 in main.tf and re-apply. Talos handles etcd member joining automatically.
