# Backend with Cloudflare Tunnel
|
|
|
|
This setup runs the Monaco backend service and establishes a Cloudflare tunnel, exposing the service to the internet securely via api.ishikabhoyar.tech.
|
|
|
|
## Prerequisites
|
|
|
|
- Docker and Docker Compose installed
|
|
- The Cloudflare tunnel certificate (cert.pem) in the same directory as the Dockerfile.tunnel
|
|
|
|
## Files
|
|
|
|
- `Dockerfile.tunnel`: Dockerfile that builds the backend and sets up Cloudflare tunnel
|
|
- `cert.pem`: Cloudflare tunnel certificate
|
|
- `config.json`: Cloudflare tunnel configuration that routes traffic to api.ishikabhoyar.tech
|
|
- `docker-compose.tunnel.yml`: Docker Compose configuration for easy deployment
|
|
|
|
## How to Run
|
|
|
|
```bash
|
|
# Build and start the container
|
|
docker-compose -f docker-compose.tunnel.yml up -d
|
|
|
|
# Check logs
|
|
docker-compose -f docker-compose.tunnel.yml logs -f
|
|
```
|
|
|
|
## How it Works
|
|
|
|
1. The Dockerfile builds the Go backend application
|
|
2. It installs the Cloudflare tunnel client (cloudflared)
|
|
3. On container start:
|
|
- The backend server starts on port 8080
|
|
- The Cloudflare tunnel connects to Cloudflare's edge network using the config.json
|
|
- External traffic to api.ishikabhoyar.tech is routed through the tunnel to the backend
|
|
- The cloudflared runs entirely within the container, isolated from any host cloudflared instance
|
|
|
|
## Environment Variables
|
|
|
|
You can customize the behavior by modifying the environment variables in the docker-compose.tunnel.yml file:
|
|
|
|
- `PORT`: The port the backend server listens on (default: 8080)
|
|
- `CONCURRENT_EXECUTIONS`: Number of concurrent code executions (default: 5)
|
|
- `QUEUE_CAPACITY`: Maximum queue capacity for code executions (default: 100)
|
|
- `DEFAULT_TIMEOUT`: Default timeout for code execution in seconds (default: 30)
|
|
- `SANDBOX_NETWORK_DISABLED`: Whether to disable network in sandbox containers (default: true)
|
|
- `SANDBOX_PIDS_LIMIT`: Process ID limit for sandbox containers (default: 50)
