name: hetzner-provisioner description: Provisions infrastructure on Hetzner Cloud with Terraform/Pulumi. Generates IaC code for CX11/CX21/CX31 instances, managed Postgres, SSL configuration, Docker deployment. Activates for deploy on Hetzner, Hetzner Cloud, budget deployment, cheap hosting, $10/month hosting.

Hetzner Cloud Provisioner

Automated infrastructure provisioning for Hetzner Cloud - the budget-friendly alternative to Vercel and AWS.

Purpose

Generate and deploy infrastructure-as-code (Terraform/Pulumi) for Hetzner Cloud, enabling $10-15/month SaaS deployments instead of $50-100/month on other platforms.

When to Use

Activates when user mentions:

• "deploy on Hetzner"
• "Hetzner Cloud"
• "budget deployment"
• "cheap hosting"
• "deploy for $10/month"
• "cost-effective infrastructure"

What It Does

1. Analyzes requirements:

   • Application type (NextJS, Node.js, Python, etc.)
   • Database needs (Postgres, MySQL, Redis)
   • Expected traffic/users
   • Budget constraints

2. Generates Infrastructure-as-Code:

   • Terraform configuration for Hetzner Cloud
   • Alternative: Pulumi for TypeScript-native IaC
   • Server instances (CX11, CX21, CX31)
   • Managed databases (Postgres, MySQL)
   • Object storage (if needed)
   • Networking (firewall rules, floating IPs)

3. Configures Production Setup:

   • Docker containerization
   • SSL certificates (Let's Encrypt)
   • DNS configuration (Cloudflare or Hetzner DNS)
   • GitHub Actions CI/CD pipeline
   • Monitoring (Uptime Kuma, self-hosted)
   • Automated backups

4. Outputs Deployment Guide:

   • Step-by-step deployment instructions
   • Cost breakdown
   • Monitoring URLs
   • Troubleshooting guide

⚠️ CRITICAL: Secrets Required (MANDATORY CHECK)

BEFORE generating Terraform/Pulumi code, CHECK for Hetzner API token.

Step 1: Check If Token Exists

# Check .env file
if [ -f .env ] && grep -q "HETZNER_API_TOKEN" .env; then
  echo "✅ Hetzner API token found"
else
  # Token NOT found - STOP and prompt user
fi

Step 2: If Token Missing, STOP and Show This Message

🔐 **Hetzner API Token Required**

I need your Hetzner API token to provision infrastructure.

**How to get it**:
1. Go to: https://console.hetzner.cloud/
2. Click on your project (or create one)
3. Navigate to: Security → API Tokens
4. Click "Generate API Token"
5. Give it a name (e.g., "specweave-deployment")
6. Permissions: **Read & Write**
7. Click "Generate"
8. **Copy the token immediately** (you can't see it again!)

**Where I'll save it**:
- File: `.env` (gitignored, secure)
- Format: `HETZNER_API_TOKEN=your-token-here`

**Security**:
✅ .env is in .gitignore (never committed to git)
✅ Token is 64 characters, alphanumeric
✅ Stored locally only (not in source code)

Please paste your Hetzner API token:

Step 3: Validate Token Format

# Hetzner tokens are 64 alphanumeric characters
if [[ ! "$HETZNER_API_TOKEN" =~ ^[a-zA-Z0-9]{64}$ ]]; then
  echo "⚠️  Warning: Token format unexpected"
  echo "Expected: 64 alphanumeric characters"
  echo "Got: ${#HETZNER_API_TOKEN} characters"
  echo ""
  echo "This might not be a valid Hetzner API token."
  echo "Continue anyway? (yes/no)"
fi

Step 4: Save Token Securely

# Save to .env
echo "HETZNER_API_TOKEN=$HETZNER_API_TOKEN" >> .env

# Ensure .env is gitignored
if ! grep -q "^\.env$" .gitignore; then
  echo ".env" >> .gitignore
fi

# Create .env.example for team
cat > .env.example << 'EOF'
# Hetzner Cloud API Token
# Get from: https://console.hetzner.cloud/ → Security → API Tokens
HETZNER_API_TOKEN=your-hetzner-token-here
EOF

echo "✅ Token saved to .env (gitignored)"
echo "✅ Created .env.example for team (commit this)"

Step 5: Use Token in Terraform

# terraform/variables.tf
variable "hetzner_token" {
  description = "Hetzner Cloud API Token"
  type        = string
  sensitive   = true
}

# terraform/provider.tf
provider "hcloud" {
  token = var.hetzner_token
}

# Run Terraform
# export TF_VAR_hetzner_token=$HETZNER_API_TOKEN
# terraform apply

Example Usage

User: "Deploy my NextJS app on Hetzner with Postgres, as cheaply as possible"

hetzner-provisioner:

I'll provision your NextJS app on Hetzner Cloud for ~$12/month.

Infrastructure:
- CX11 instance (2 vCPU, 2GB RAM): $5.83/month
- Managed Postgres (2GB): $5.00/month
- 20GB storage: $0.50/month
- SSL (Let's Encrypt): Free
- Total: ~$11.33/month

Creating Terraform configuration...

✅ Generated files:
- terraform/main.tf
- terraform/variables.tf
- terraform/outputs.tf
- .github/workflows/deploy.yml

Next steps:
1. Set HETZNER_API_TOKEN in GitHub secrets
2. Push to GitHub
3. GitHub Actions will deploy automatically

Deployment URL: https://your-app.yourdomain.com (after DNS configured)

Configuration

Supports multiple instance types:

• CX11 (1 vCPU, 2GB RAM): $5.83/month - Small apps, 100-1000 users
• CX21 (2 vCPU, 4GB RAM): $6.90/month - Medium apps, 1000-10000 users
• CX31 (2 vCPU, 8GB RAM): $14.28/month - Larger apps, 10000+ users

Database options:

• Managed Postgres (2GB): $5/month
• Managed MySQL (2GB): $5/month
• Self-hosted (included in instance cost)

Test Cases

See test-cases/ for validation scenarios:

1. test-1-basic-provision.yaml - Basic CX11 instance
2. test-2-postgres-provision.yaml - Add managed Postgres
3. test-3-ssl-config.yaml - SSL and DNS configuration

Cost Comparison

Platform	Small App	Medium App	Large App
Hetzner	$12/mo	$15/mo	$25/mo
Vercel	$60/mo	$120/mo	$240/mo
AWS	$25/mo	$80/mo	$200/mo
Railway	$20/mo	$50/mo	$100/mo

Savings: 50-80% vs alternatives

Technical Details

Terraform Provider: hetznercloud/hcloud API: Hetzner Cloud API v1 Regions: Nuremberg, Falkenstein, Helsinki (Germany/Finland) Deployment: Docker + GitHub Actions Monitoring: Uptime Kuma (self-hosted, free)

Integration

Works with:

• cost-optimizer - Recommends Hetzner when budget-conscious
• devops-agent - Strategic infrastructure planning
• nextjs-agent - NextJS-specific deployment
• Any backend framework (Node.js, Python, Go, etc.)

Limitations

• EU-only data centers (GDPR-friendly)
• Requires Hetzner Cloud account
• Manual DNS configuration needed
• Not suitable for multi-region deployments (use AWS/GCP for that)

Future Enhancements

• Kubernetes support (k3s on Hetzner)
• Load balancer configuration
• Multi-region deployment
• Disaster recovery setup
