Cloudflare Tunnels

Cloudflare Tunnels provide secure, encrypted connections to your homelab services from anywhere in the world without opening ports on your firewall or exposing your home IP address.

Cloudflare Tunnels eliminate the need for port forwarding, dynamic DNS, or VPN setups while providing enterprise-grade security and performance.

Quick Start Guides

High Availability Setup

Configure Cloudflare Tunnels with ingress rules and HA deployment

What are Cloudflare Tunnels?

Cloudflare Tunnels create secure, outbound-only connections from your infrastructure to Cloudflare's edge network. This approach offers several advantages:

Key Benefits

No Port Forwarding: Services remain behind your firewall
Hide Origin IP: Your home IP address stays private
Built-in DDoS Protection: Cloudflare's network protects your services
SSL/TLS Termination: Automatic HTTPS with Cloudflare certificates
Global Performance: Cloudflare's CDN accelerates your services
Access Control: Granular authentication and authorization policies

How It Works

[Your Services] ←→ [cloudflared] ←→ [Cloudflare Edge] ←→ [Internet Users]

cloudflared daemon runs on your server
Creates secure tunnel to Cloudflare's edge network
Cloudflare routes traffic to your services through the tunnel
Users access your services via Cloudflare's global network

Kubernetes

Deploy as Kubernetes pods with Helm charts

Package Managers

Install via apt, yum, brew, or chocolatey

Configuration Examples

Basic Web Service

tunnel: my-tunnel-id
credentials-file: /path/to/credentials.json

ingress:
  - hostname: app.example.com
    service: http://localhost:8080
  - service: http_status:404

Docker Services

ingress:
  - hostname: web.example.com
    service: http://web-container:80
  - hostname: api.example.com
    service: http://api-container:3000
  - service: http_status:404

Multiple Services

ingress:
  - hostname: nextcloud.example.com
    service: http://localhost:8080
  - hostname: plex.example.com
    service: http://localhost:32400
  - hostname: grafana.example.com
    service: http://localhost:3000
  - service: http_status:404

Management and Monitoring

Cloudflare Dashboard

Tunnel status and health
Traffic analytics and metrics
Access logs and audit trails
Configuration management

Command Line Tools

# List all tunnels
cloudflared tunnel list

# Check tunnel status
cloudflared tunnel info my-tunnel

# View tunnel logs
cloudflared tunnel logs my-tunnel

# Test tunnel connectivity
cloudflared tunnel test my-tunnel

Health Checks

Built-in health monitoring
Custom health check endpoints
Automatic failover on failures
Integration with monitoring systems

Best Practices

Security

Use unique tunnel credentials for each environment
Implement proper access policies
Regular credential rotation
Monitor access logs

Performance

Deploy tunnels close to your services
Use appropriate service URLs (avoid localhost when possible)
Configure proper timeout values
Monitor tunnel latency

Reliability

Set up multiple tunnel instances for HA
Use health checks for automatic failover
Monitor tunnel connectivity
Have backup access methods

Troubleshooting

Common Issues

Connection failures: Check firewall and network connectivity
DNS resolution: Verify Cloudflare DNS settings
Service unreachable: Confirm service URLs and ports
Authentication errors: Validate tunnel credentials

Debugging Tools

# Enable debug logging
cloudflared tunnel --loglevel debug run my-tunnel

# Test specific hostname
curl -H "Host: app.example.com" http://localhost:8080

# Check tunnel connectivity
cloudflared tunnel test my-tunnel
