Hetzner VPS Provisioning

Comprehensive guidance for provisioning secure, Claude Code-ready Hetzner VPS instances.

Overview

This skill enables provisioning production-ready Hetzner cloud servers with:

  • Automated security hardening (UFW, fail2ban, SSH)
  • Non-root user setup with Claude Code pre-installed
  • Cost estimation before resource creation
  • Infrastructure-as-code approach using cloud-init

Available Scripts

All scripts located at ${CLAUDE_PLUGIN_ROOT}/scripts/:

Script Purpose
provision.sh Create and configure a secure VPS
cost-estimate.sh Estimate monthly costs
status.sh Check server status
destroy.sh Safely delete a server

Core Workflow

1. Prerequisites Verification

Before any provisioning, verify:

bash
# Check hcloud CLI
which hcloud

# Test authentication
hcloud server list

# Find SSH key
ls -la ~/.ssh/id_ed25519.pub ~/.ssh/id_rsa.pub 2>/dev/null

If prerequisites fail, guide user through setup.

2. Cost Estimation (ALWAYS First)

Never provision without showing costs:

bash
bash "${CLAUDE_PLUGIN_ROOT}/scripts/cost-estimate.sh" "cx22"

Require explicit user confirmation before proceeding.

3. Server Provisioning

After cost confirmation:

bash
bash "${CLAUDE_PLUGIN_ROOT}/scripts/provision.sh" "server-name" "cx22" "nbg1"

4. Status Check

bash
bash "${CLAUDE_PLUGIN_ROOT}/scripts/status.sh" "server-name"

5. Server Destruction

Requires explicit confirmation:

bash
CONFIRM_DESTROY=yes bash "${CLAUDE_PLUGIN_ROOT}/scripts/destroy.sh" "server-name"

Server Type Selection

Recommend based on use case:

Use Case Type Specs Cost
Development/Testing cx22 2 vCPU, 4GB ~4.49 EUR
Budget-friendly cax11 2 ARM, 4GB ~3.79 EUR
Small production cx32 4 vCPU, 8GB ~8.98 EUR
Medium production cx42 8 vCPU, 16GB ~17.96 EUR

Location Selection

Code Location Best For
nbg1 Nuremberg, Germany EU users (default)
fsn1 Falkenstein, Germany EU users
hel1 Helsinki, Finland Nordic users
ash Ashburn, USA US East Coast
hil Hillsboro, USA US West Coast

Security Implementation

UFW Firewall

bash
# Default rules applied:
ufw default deny incoming
ufw default allow outgoing
ufw allow 22/tcp
ufw --force enable

Users can add web server ports later:

bash
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp

fail2ban Configuration

  • SSH jail enabled
  • Max retries: 5
  • Ban time: 1 hour
  • Find time: 10 minutes

SSH Hardening

  • PermitRootLogin: no
  • PasswordAuthentication: no
  • PubkeyAuthentication: yes
  • MaxAuthTries: 3

Error Handling

Error Cause Solution
hcloud not found CLI not installed Install via Homebrew or GitHub
unauthorized Invalid API token Create new token in Hetzner Console
name_already_used Server exists Choose different name or delete existing
SSH key not found No public key Generate with ssh-keygen

Important Notes

  1. Cost Transparency: Always show costs before provisioning
  2. Confirmation Required: Never auto-confirm destructive operations
  3. Security First: All servers get hardened by default
  4. Wait for Cloud-init: Server ready ~2 minutes after creation
