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
