Fully Automated Talos Cluster on Hetzner Cloud

This script completely automates the creation and destruction of a production-ready, secure Kubernetes cluster using Talos on Hetzner Cloud.

It is fully idempotent, meaning it can be run multiple times without causing errors. If resources already exist, it will adopt them; if they don't, it will create them. The script handles everything from provisioning servers and networking to configuring the Kubernetes control plane with all necessary patches for a cloud environment.

To Do

• Add the best, most universally accepted control panel(s) (kube-prometheus-stack? ArgoCD? others? -> research)
• Add k8s MCP server, deploy LibreChat and connect the two.

Features

• Fully Automated: From zero to a running Kubernetes cluster with a single command.
• Idempotent: Safe to re-run. The script intelligently creates or adopts existing infrastructure.
• Production-Ready:
  • High-Availability Ready: Uses a floating IP for a stable control plane endpoint.
  • Secure by Default: Deploys Talos with a minimal attack surface and an encrypted network backend (KubeSpan via WireGuard).
  • Correctly Patched: Automatically applies the necessary patches for NAT reflection (hairpinning) and public API access.
• Easy Cleanup: A simple --wipe command de-provisions all created cloud resources.

Prerequisites

Before you begin, make sure you have the following tools installed on your local machine:

1. Hetzner Cloud CLI: hcloud
   • You must have a context created and active: hcloud context create my-project
2. Kubernetes CLI: kubectl
3. Talos CLI: talosctl
4. Helper Tools: jq, dig, and nc (netcat)

Configuration

All user-configurable variables are located at the top of the setup-talos-hcloud.sh script. You must edit these before running the script for the first time.

# --- ⚙️ Cluster Configuration (CHANGE THESE VALUES) ---# A unique name for your cluster. Used for naming and labeling all resources.readonly CLUSTER_NAME="divizend-ai-prod"# The DNS name you will point to the cluster's Floating IP.readonly CLUSTER_ENDPOINT_DNS="k8s-api.divizend.ai"# Hetzner Cloud settingsreadonly HCLOUD_LOCATION="fsn1"# Falkensteinreadonly HCLOUD_CP_TYPE="cpx21"# Control Plane server typereadonly HCLOUD_WORKER_TYPE="cpx21"# Worker server typereadonly HCLOUD_WORKER_COUNT=2 # Number of worker nodesreadonly HCLOUD_TALOS_ISO="122630"# Specific Talos ISO ID

Usage

Make the script executable first:

chmod +x setup-talos-hcloud.sh

To Create the Cluster

Simply run the script. It will guide you through the process.

./setup-talos-hcloud.sh

The script will provision all resources and, upon completion, generate two important files in your current directory:

• divizend-ai-prod.kubeconfig: Your kubeconfig file for accessing the cluster with kubectl.
• clusterconfig_divizend-ai-prod/: A directory containing the sensitive Talos PKI infrastructure. Keep this directory safe!

To Destroy the Cluster

To completely remove all cloud infrastructure created by this script, use the --wipe flag.

./setup-talos-hcloud.sh --wipe

This command will find all resources associated with your CLUSTER_NAME label and permanently delete them.
