Issue: Implement Persistent Storage Provisioning with Hetzner CSI Driver

Objective
Enable dynamic provisioning of Hetzner Cloud Volumes for Kubernetes workloads through CSI driver integration.

Acceptance Criteria

• PVCs automatically create Hetzner Cloud Volumes
• Volumes attach to worker nodes
• StorageClass hcloud-volumes available cluster-wide
• Docs site persists data through pod restarts
• Automatic volume cleanup on PVC deletion

Technical Requirements

1. CSI Driver Components

   • Controller Deployment with Hetzner API access
   • Node DaemonSet with hostPath mounts
   • Proper RBAC permissions

2. Storage Configuration

   apiVersion: storage.k8s.io/v1
   kind: StorageClass
   metadata:
     name: hcloud-volumes
   provisioner: csi.hetzner.cloud
   reclaimPolicy: Delete
   volumeBindingMode: WaitForFirstConsumer
   parameters:
     type: hdd

3. Security

   • Encrypted API token in Kubernetes Secret
   • Privileged containers only where absolutely required

Dependencies

• Hetzner Cloud API token with write permissions
• Kubernetes 1.25+ cluster
• CSI driver v2.11.0+ manifests

Testing Plan

1. Deploy test PVC
2. Verify volume creation in Hetzner Cloud Console
3. Deploy test pod mounting PVC
4. Validate data persistence across pod restarts

Progress has been made, hetzner volume controller and node running. Still not fully tested. Merging changes so far.

Status:

pod/hcloud-csi-controller-66c969bc8-g4tl9   5/5     Running   0             11m
pod/hcloud-csi-node-v4qxq                   3/3     Running   0             11m
