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