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:

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

Require explicit user confirmation before proceeding.

3. Server Provisioning

After cost confirmation:

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

4. Status Check

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

5. Server Destruction

Requires explicit confirmation:

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

# 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:

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
