 # Monaco Code Execution Engine
-Monaco is a secure, containerized code execution engine that allows you to run code in multiple programming languages through a simple REST API.
+
+Monaco is a secure, containerized code execution engine that allows you to run code in multiple programming languages through a simple REST API and WebSocket connections for real-time terminal interaction. Gitea

 ## Features
- Multi-language support: Run code in Python, Java, C, and C++
- Secure execution: All code runs in isolated Docker containers
- Resource limits: Memory, CPU, and file descriptor limits to prevent abuse
- Concurrent processing: Efficient job queue for handling multiple requests
- Simple REST API: Easy to integrate with any frontend
+
+- **Multi-language support**: Run code in Python, Java, C, and C++
+- **Secure execution**: All code runs in isolated Docker containers
+- **Resource limits**: Memory, CPU, and file descriptor limits to prevent abuse
+- **Concurrent processing**: Efficient job queue for handling multiple requests
+- **Simple REST API**: Easy to integrate with any frontend
+- **Interactive terminal**: Real-time code execution with input/output via WebSockets
+- **VS Code-like interface**: Modern editor with syntax highlighting and file management

 ## Architecture
+
 Monaco consists of several components:

- HTTP Handlers (handler/handler.go): Processes API requests
- Execution Service (service/execution.go): Manages code execution in containers
- Job Queue (queue/queue.go): Handles concurrent execution of code submissions
- Submission Model (model/submission.go): Defines the data structure for code submissions
+### Backend Components
+
+- **HTTP Handlers** (`handler/handler.go`): Processes API requests and WebSocket connections
+- **Execution Service** (`service/execution.go`): Manages code execution in containers
+- **Job Queue** (`queue/queue.go`): Handles concurrent execution of code submissions
+- **Submission Model** (`model/submission.go`): Defines the data structure for code submissions
+
+### Frontend Components
+
+- **Editor Area** (`EditorArea.jsx`): Main code editor with Monaco editor integration
+- **Terminal Panel** (`Panel.jsx`): Interactive terminal for code execution and input
+- **Sidebar** (`Sidebar.jsx`): File explorer and project structure navigation
+- **Status Bar** (`StatusBar.jsx`): Information display and quick actions
+
+### Communication Flow
+
+1. Frontend submits code to backend via REST API
+2. Backend assigns a unique ID and queues the execution
+3. Frontend connects to WebSocket endpoint with the execution ID
+4. Backend sends real-time execution output through WebSocket
+5. Frontend can send user input back through WebSocket
+6. Results are stored and retrievable via REST endpoints

 ## Requirements
- Go 1.22.3 or higher
- Docker
- Network connectivity for container image pulling
+
+- **Backend**:
+  - Go 1.22.3 or higher
+  - Docker
+  - Network connectivity for container image pulling
+- **Frontend**:
+  - Node.js and npm/yarn
+  - Modern web browser
+
+## Installation
+
+### Backend Setup
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/arnab-afk/monaco.git
+   cd monaco/backend
+
+2.Install Go dependencies:
+
+```bash
+    go mod download
+```
+
+3.Build the application:
+```bash
+go build -o monaco
+```
+
+4.Run the service
+```bash
+    ./monaco
+```
+
+The backend service will start on port 8080 by default.
+
+### Frontend Setup
+1. Navigate to the Frontend directory:
+```bash
+cd Frontend
+```
+
+2. Install dependencies:
+```bash
+npm install
+```
+
+3. Set up environment variables: Create a ```.env``` or ```.env.local.``` file with:
+```bash
+VITE_API_URL=http://localhost:8080
+```
+
+4. Start the development server:
+```bash
+npm run dev
+```
+
+The frontend will be available at http://localhost:5173 by default.
+
+### API Reference
+
+### REST Endpoints
+```POST /submit```
+
+Submits code for execution
+```json
+{
+  "language": "python",
+  "code": "print('Hello, World!')",
+  "input": ""
+}
+```
+
+Response:
+```json
+{
+  "id": "6423259c-ee14-c5aa-1c90-d5e989f92aa1"
+}
+```
+
+```GET /status?id={submissionId}```
+
+Checks the status of submission:
+```json
+{
+  "id": "6423259c-ee14-c5aa-1c90-d5e989f92aa1", 
+  "status": "completed",
+  "queuedAt": "2025-03-25T14:30:00Z",
+  "startedAt": "2025-03-25T14:30:01Z",
+  "completedAt": "2025-03-25T14:30:02Z",
+  "executionTime": 1000
+}
+```
+
+```GET /result?id={submissionId}```
+
+Gets the execution result of a submission.
+
+Response:
+```json
+{
+  "id": "6423259c-ee14-c5aa-1c90-d5e989f92aa1",
+  "status": "completed",
+  "language": "python",
+  "output": "Hello, World!",
+  "queuedAt": "2025-03-25T14:30:00Z",
+  "startedAt": "2025-03-25T14:30:01Z",
+  "completedAt": "2025-03-25T14:30:02Z",
+  "executionTime": 1000,
+  "executionTimeFormatted": "1.0s",
+  "totalTime": 2000,
+  "totalTimeFormatted": "2.0s"
+}
+```
+
+```GET /queue-stats```
+Gets the statistics about the job queue.
+
+Response:
+```json
+{
+  "queue_stats": {
+    "queue_length": 5,
+    "max_workers": 3,
+    "running_jobs": 3
+  },
+  "submissions": 42
+}
+```
+
+### WebSocket Endpoints
+```ws://localhost:8080/ws/terminal?id={submissionId}```
+
+Establishes a real-time connection for terminal interaction.
+
+- The server sends execution output as plain text messages.
+- The client can send input as plain text messages (with newline).
+- Connection automatically closes when execution completes or fails.
+
+### Terminal Input Handling
+The system supports interactive programs requiring user input:
+
+1. The frontend detects possible input prompts by looking for patterns
+2. When detected, it focuses the terminal and allows user input
+3. User input is captured in the terminal component's inputBuffer
+4. When the user presses Enter, the input is:
+    - Sent to the backend via WebSocket.
+    - Displayed in the terminal.
+    - Buffer is cleared for next input.
+5. The input is processed by the running program in real-time.
+
+
+Troubleshooting tips:
+
+- Ensure WebSocket connection is established before sending input
+- Check for WebSocket errors in console
+- Verify input reaches the backend by checking server logs
+- Ensure newline characters are properly appended to input.
+
+### Language Support
+### Python
+- **Version**: Python 3.9
+- **Input Handling**: Direct stdin piping
+- **Limitations**: No file I/O, no package imports outside standard library
+- **Resource Limits**: 100MB memory, 10% CPU
+### Java
+- **Version**: Java 11 (Eclipse Temurin)
+- **Class Detection**: Extracts class name from code using regex.
+- **Memory Settings**: 64MB min heap, 256MB max heap
+- **Resource Limits**: 400MB memory, 50% CPU
+C
+- **Version**: Latest GCC
+- **Compilation Flags**: Default GCC settings
+- **Resource Limits**: 100MB memory, 10% CPU
+
+### C++
+- **Version**: Latest G++
+- **Standard**: C++17
+- **Resource Limits**: 100MB memory, 10% CPU
+
+### Security Considerations
+All code execution happens within isolated Docker containers with:
+
+- No network access (```--network=none```)
+- Limited CPU and memory resources
+- Limited file system access
+- No persistent storage
+- Execution time limits (10-15 seconds)
+
+### Debugging
+Check backend logs for execution details
+Use browser developer tools to debug WebSocket connections
+Terminal panel shows WebSocket connection status and errors
+Check Docker logs for container-related issues.
+
+### Contributing
+Contributions are welcome! Please feel free to submit a Pull Request :).

-## Introduction
-
-Monaco is a secure, containerized code execution backend service designed to run user-submitted code in multiple programming languages. It features a job queue system to manage execution resources, containerized execution environments for security, and a RESTful API for submission and monitoring.
-
-**Key Features:**
- Multi-language support (Python, Java, C, C++)
- Secure containerized execution using Docker
- Resource limiting to prevent abuse
- Job queuing for managing concurrent executions
- Detailed execution statistics and monitoring
- Support for user input via stdin
- CORS support for browser-based clients
-
-## Architecture
-
-### Component Overview
-
-Monaco follows a layered architecture with the following key components:
-
-1. **HTTP Handlers** (handler package) - Processes incoming HTTP requests
-2. **Execution Service** (service package) - Manages code execution in containers
-3. **Job Queue** (queue package) - Controls concurrent execution
-4. **Data Models** (model package) - Defines data structures
-
-### Request Flow
-
-1. Client submits code via `/submit` endpoint
-2. Request is validated and assigned a unique ID
-3. Submission is added to the job queue
-4. Worker picks job from queue when available
-5. Code is executed in appropriate Docker container
-6. Results are stored and available via `/result` endpoint
-
-### Dependency Diagram
-

-  "submissions": 42
-}
-```
-
-## Code Execution
-
-### Execution Process
-
-1. **Language Detection**: The system identifies the programming language of the submission.
-2. **Environment Setup**: A temporary directory is created for compiled languages.
-3. **Container Setup**: Docker containers are configured with resource limits.
-4. **Compilation**: For compiled languages (Java, C, C++), code is compiled first.
-5. **Execution**: The program is executed with the provided input.
-6. **Resource Monitoring**: Memory and CPU usage are limited during execution.
-7. **Result Collection**: Output and errors are captured and stored.
-
-### Language-Specific Processing
-
-#### Python
- Directly executes Python code using the `-c` flag
- Uses `python:3.9` Docker image
- Resource limits: 100MB memory, 10% CPU
-
-#### Java
- Detects class name using regex pattern matching
- Compiles with `javac` and runs with optimized JVM settings
- Uses `eclipse-temurin:11-jdk-alpine` Docker image
- Resource limits: 400MB memory, 50% CPU
- JVM flags: `-XX:+TieredCompilation`, `-XX:TieredStopAtLevel=1`, `-Xverify:none`
-
-#### C/C++
- Saves code to a file in a temporary directory
- Compiles with `gcc`/`g++` and runs the executable
- Uses `gcc:latest` Docker image
- Resource limits: 100MB memory, 10% CPU
-
-### Timeout Handling
-
-All executions have a timeout limit:
- Python: 10 seconds
- Java: 15 seconds
- C/C++: 10 seconds
-
-If execution exceeds this limit, the process is killed and an error is returned.
-
-## Job Queue System
-
-### Worker Pool
-
-Monaco uses a worker pool to manage concurrent code executions:
-
- Default pool size: 20 workers (configurable)
- Maximum queue capacity: 100 jobs
- FIFO (First-In-First-Out) processing order
-
-### Job Lifecycle
-
-1. **Creation**: Job created when code is submitted
-2. **Queuing**: Job added to queue with `queued` status
-3. **Execution**: Worker picks job from queue and changes status to `running`
-4. **Completion**: Job finishes with either `completed` or `failed` status
-
-### Performance Metrics
-
-The queue tracks and reports:
- Current queue length
- Number of running jobs
- Maximum worker count
- Total number of submissions
-
-## Language Support
-
-### Python
- **Version**: Python 3.9
- **Input Handling**: Direct stdin piping
- **Limitations**: No file I/O, no package imports outside standard library
-
-### Java
- **Version**: Java 11 (Eclipse Temurin)
- **Class Detection**: Extracts class name from code using regex
- **Memory Settings**: 64MB min heap, 256MB max heap
- **Best Practices**: Use `public class` with the main method
-
-### C
- **Version**: Latest GCC
- **Compilation Flags**: Default GCC settings
- **Execution**: Compiled binary
-
-### C++
- **Version**: Latest G++
- **Standard**: C++17
- **Execution**: Compiled binary
-
-## Security Considerations
-
-### Containerization
-
-All code execution happens within isolated Docker containers with:
- No network access (`--network=none`)
- Limited CPU and memory resources
- Limited file system access
- No persistent storage
-
-### Resource Limiting
-
- **Memory Limits**: 100-400MB depending on language
- **CPU Limits**: 10-50% of CPU depending on language
- **File Descriptors**: Limited to 64 for Python
- **Execution Time**: Enforced timeouts (10-15 seconds)
-
-### Known Limitations
-
- Container escape vulnerabilities
- Docker daemon security depends on host configuration
- Resource limits can be circumvented with certain techniques
-
-## Configuration
-
-The service can be configured through environment variables:
-
- `PORT`: HTTP port (default: 8080)
- `MAX_WORKERS`: Maximum concurrent executions (default: 3)
- `QUEUE_SIZE`: Maximum queue size (default: 100)
- `DEFAULT_LANGUAGE`: Default language if none specified (default: "python")
-
-## Testing
-
-### Unit Tests
-
-Run unit tests with:
-```bash
-go test ./...
-```
-
-# Monaco Backend Test Plan
-
-## Overview
-This test plan outlines the testing approach for the Monaco code execution backend service.
-
-## Test Environment
- Development: Local workstations with Docker and Go
- Testing: Dedicated test server with Docker
- Production-like: Staging environment with similar resources to production
-
-## Test Types
-
-### Unit Tests
- **Purpose**: Verify individual components work as expected
- **Components to Test**:
-  - Handler package
-  - Queue package
-  - Execution service
-  - Models
- **Tools**: Go testing framework
-
-### Integration Tests
- **Purpose**: Verify components work together correctly
- **Focus Areas**:
-  - API endpoints
-  - End-to-end code execution flow
-  - Error handling
- **Tools**: Go testing framework, HTTP test utilities
-
-### Load Tests
- **Purpose**: Verify system performance under load
- **Scenarios**:
-  - Concurrent submissions
-  - Mixed language workloads
-  - Queue saturation
- **Metrics**:
-  - Request throughput
-  - Response times
-  - Success rates
-  - Resource utilization
- **Tools**: Custom Python test scripts
-
-## Test Data
- Simple programs in each language
- Programs with input requirements
- Programs with compile errors
- Programs with runtime errors
- Programs with timeouts
-
-## Test Execution
-1. Run unit tests on every code change
-2. Run integration tests before merging to main branch
-3. Run load tests weekly and before major releases
-
-## Success Criteria
- All unit tests pass
- Integration tests complete successfully
- Load tests show acceptable performance metrics:
-  - 95% of requests complete successfully
-  - 95th percentile response time < 5 seconds
-  - System can handle 20 concurrent users
-
-## Reporting
- Test results stored in CI/CD pipeline
- Performance metrics graphed over time
- Issues logged in GitHub issues
-
-### Load Testing
-
-A Python script (`test.py`) is included for load testing:
-```bash
-python test.py
-```
-
-This script sends 500 requests concurrently and reports performance metrics.
-
-### Manual Testing with Curl
-
-#### Python Example
-```bash
-curl -X POST http://localhost:8080/submit \
-  -H "Content-Type: application/json" \
-  -d '{
-    "language": "python",
-    "code": "print(\"Hello, World!\")\nfor i in range(5):\n    print(f\"Number: {i}\")",
-    "input": ""
-  }'
-```
-
-#### Java Example
-```bash
-curl -X POST http://localhost:8080/submit \
-  -H "Content-Type: application/json" \
-  -d '{
-    "language": "java",
-    "code": "public class Solution {\n    public static void main(String[] args) {\n        System.out.println(\"Hello, World!\");\n        for (int i = 0; i < 5; i++) {\n            System.out.println(\"Number: \" + i);\n        }\n    }\n}",
-    "input": ""
-  }'
-```
-
-## Performance Tuning
-
-### Optimizing Worker Count
-
-The optimal worker count depends on:
- CPU cores available
- Memory available
- Docker container startup time
-
-For most single-server deployments, 3-5 workers is optimal.
-
-### Memory Considerations
-
-Each language has different memory requirements:
- Python: ~50-100MB per instance
- Java: ~200-400MB per instance
- C/C++: ~50-100MB per instance
-
-Calculate total memory needs as: `(Python instances × 100MB) + (Java instances × 400MB) + (C/C++ instances × 100MB)`
-
-### Disk Space Management
-
-Temporary files are cleaned up after execution, but with high request volumes, ensure adequate disk space for concurrent operations (approximately 1-5MB per request for compiled languages).
-
-## Troubleshooting
-
-### Common Issues
-
-#### Docker Connection Errors
-```
-Error: Cannot connect to the Docker daemon
-```
-**Solution**: Ensure Docker daemon is running with `systemctl start docker` or `docker --version`
-
-#### Permissions Issues
-```
-Error: Permission denied while trying to connect to the Docker daemon socket
-```
-**Solution**: Add user to docker group: `sudo usermod -aG docker $USER`
-
-#### Container Resource Limits
-```
-Error: Container killed due to memory limit
-```
-**Solution**: Increase memory limits in execution service or optimize submitted code
-
-#### File Not Found Errors
-```
-Error: Failed to write Java file
-```
-**Solution**: Check temporary directory permissions and disk space
-
-### Logs
-
-The service provides structured logs with prefixes for easier filtering:
- `[HTTP]` - API requests
- `[QUEUE]` - Queue operations
- `[WORKER-n]` - Worker activities
- `[EXEC-id]` - Execution details
- `[PYTHON/JAVA/C/CPP-id]` - Language-specific logs
- `[TIMEOUT-id]` - Timeout events
- `[RESULT-id]` - Execution results

+# Monaco Code Execution Backend
+
+A modern, secure, and efficient code execution backend inspired by online code editors like Programiz. This backend is written in Go and uses Docker containers for secure code execution.
+
+## Features
+
+- **Multi-language Support**: Execute code in Python, Java, C, C++, JavaScript, and Go
+- **Real-time Output**: Stream code execution output via WebSockets
+- **Interactive Input**: Send input to running programs via WebSockets
+- **Secure Execution**: All code runs in isolated Docker containers
+- **Resource Limits**: Memory, CPU, and execution time limits
+- **Scalable Architecture**: Concurrent execution with configurable worker pools
+
+## Requirements
+
+- Go 1.19+
+- Docker
+- Git (for development)
+
+## Getting Started
+
+### Running Locally
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/your-username/monaco.git
+   cd monaco/new-backend
+   ```
+
+2. Install dependencies:
+   ```bash
+   go mod download
+   ```
+
+3. Build and run:
+   ```bash
+   go run main.go
+   ```
+
+The server will start on `http://localhost:8080` by default.
+
+### Using Docker
+
+Build and run using Docker:
+
+```bash
+docker build -t monaco-backend .
+docker run -p 8080:8080 -v /var/run/docker.sock:/var/run/docker.sock monaco-backend
+```
+
+Note: Mounting the Docker socket is necessary for container-in-container execution.
+
+## API Endpoints
+
+- `POST /api/submit`: Submit code for execution
+- `GET /api/status/{id}`: Get execution status
+- `GET /api/result/{id}`: Get complete execution result
+- `GET /api/languages`: List supported languages
+- `GET /api/health`: Health check endpoint
+- `WS /api/ws/terminal/{id}`: WebSocket for real-time output
+
+## WebSocket Communication
+
+The `/api/ws/terminal/{id}` endpoint supports these message types:
+
+- `output`: Code execution output
+- `input`: User input to the program
+- `input_prompt`: Input prompt detected
+- `status`: Execution status updates
+- `error`: Error messages
+
+## Configuration
+
+Configuration is handled through environment variables:
+
+- `PORT`: Server port (default: 8080)
+- `CONCURRENT_EXECUTIONS`: Number of concurrent executions (default: 5)
+- `QUEUE_CAPACITY`: Execution queue capacity (default: 100)
+- `DEFAULT_TIMEOUT`: Default execution timeout in seconds (default: 30)
+
+See `config/config.go` for more configuration options.
+

+# Monaco Backend - Tunnel Only Setup
+
+This setup runs **only the Cloudflare tunnel** in Docker, while the backend runs **outside Docker on port 9090**.
+
+## Prerequisites
+
+1. Backend must be running on port 9090 on your local machine
+2. Required files in this directory:
+   - `cert.pem` - Cloudflare tunnel certificate
+   - `credentials.json` - Cloudflare tunnel credentials
+   - `config.tunnel-only.json` - Tunnel configuration (points to port 9090)
+
+## Setup
+
+### 1. Start your backend on port 9090
+
+Run your Go backend locally:
+```bash
+# Option 1: Run directly
+PORT=9090 go run main.go
+
+# Option 2: Build and run
+go build -o main
+PORT=9090 ./main
+```
+
+### 2. Start the tunnel
+
+In this directory, run:
+```bash
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+Or run in detached mode:
+```bash
+docker-compose -f docker-compose.tunnel-only.yml up --build -d
+```
+
+### 3. Check logs
+
+```bash
+docker-compose -f docker-compose.tunnel-only.yml logs -f
+```
+
+## How It Works
+
+1. The tunnel container runs only `cloudflared`
+2. It connects to Cloudflare's edge network
+3. Traffic from `api.ishikabhoyar.tech` is routed through the tunnel
+4. The tunnel forwards requests to `host.docker.internal:9090` (your local backend)
+5. Your backend on port 9090 handles the requests and sends responses back
+
+## Configuration
+
+The tunnel is configured in `config.tunnel-only.json`:
+```json
+{
+  "tunnel": "5d2682ef-0b5b-47e5-b0fa-ad48968ce016",
+  "credentials-file": "/etc/cloudflared/credentials.json",
+  "ingress": [
+    {
+      "hostname": "api.ishikabhoyar.tech",
+      "service": "http://host.docker.internal:9090"
+    },
+    {
+      "service": "http_status:404"
+    }
+  ],
+  "protocol": "http2",
+  "loglevel": "info"
+}
+```
+
+## Troubleshooting
+
+### Tunnel can't reach backend
+- Make sure your backend is running on port 9090
+- Test locally: `curl http://localhost:9090`
+- Check firewall settings
+
+### Tunnel connection issues
+- Verify `credentials.json` and `cert.pem` are valid
+- Check tunnel status in Cloudflare dashboard
+- Review logs: `docker-compose -f docker-compose.tunnel-only.yml logs -f`
+
+### DNS not resolving
+- DNS routing should be set up during first build
+- Verify in Cloudflare dashboard under Zero Trust > Networks > Tunnels
+
+## Stop the tunnel
+
+```bash
+docker-compose -f docker-compose.tunnel-only.yml down
+```
+
+## Architecture
+
+```
+Internet
+   ↓
+Cloudflare Edge (api.ishikabhoyar.tech)
+   ↓
+Cloudflare Tunnel (in Docker)
+   ↓
+host.docker.internal:9090
+   ↓
+Your Backend (running locally)
+```
+
+## Notes
+
+- The tunnel only forwards traffic; it doesn't run the backend
+- Backend must be started before or after the tunnel (order doesn't matter)
+- If backend restarts, tunnel will automatically reconnect
+- Port 9090 is not exposed to the internet, only accessible via the tunnel

+# 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)

+# Tunnel Connection Options - Troubleshooting Guide
+
+## The Problem
+When the tunnel runs in Docker and tries to reach your backend on the host, there are different ways to address the host machine. The method that works depends on your Docker setup.
+
+## Solution 1: Direct Bridge IP (config.tunnel-only.json) ✅ WORKING
+
+**Files:** 
+- `Dockerfile.tunnel-only`
+- `docker-compose.tunnel-only.yml`
+- `config.tunnel-only.json` (updated to use `172.18.0.1:9090`)
+
+**How it works:**
+- Uses the Docker bridge network IP directly
+- You verified this works: `curl 172.18.0.1:9090` ✅
+
+**Usage:**
+```bash
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+**Config:**
+```json
+"service": "http://172.18.0.1:9090"
+```
+
+## Solution 2: Host Network Mode (NEW - Recommended for Linux)
+
+**Files:**
+- `Dockerfile.tunnel-only-v2`
+- `docker-compose.tunnel-only-v2.yml`
+- `config.tunnel-only-v2.json` (uses `localhost:9090`)
+
+**How it works:**
+- Container runs in host network mode
+- Can access `localhost:9090` directly as if running on host
+
+**Usage:**
+```bash
+docker-compose -f docker-compose.tunnel-only-v2.yml up --build
+```
+
+**Config:**
+```json
+"service": "http://localhost:9090"
+```
+
+**Note:** Host network mode works best on Linux. May have limitations on Windows/Mac.
+
+## Quick Test Guide
+
+### 1. Rebuild and restart with updated config (Solution 1)
+```bash
+# Stop current tunnel
+docker-compose -f docker-compose.tunnel-only.yml down
+
+# Rebuild with updated config (now uses 172.18.0.1)
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+### 2. Or try host network mode (Solution 2)
+```bash
+docker-compose -f docker-compose.tunnel-only-v2.yml up --build
+```
+
+## Expected Success Output
+```
+INF Registered tunnel connection connIndex=0 connection=xxx event=0 ip=xxx location=bom protocol=http2
+INF Registered tunnel connection connIndex=1 connection=xxx event=0 ip=xxx location=bom protocol=http2
+INF Registered tunnel connection connIndex=2 connection=xxx event=0 ip=xxx location=bom protocol=http2
+INF Registered tunnel connection connIndex=3 connection=xxx event=0 ip=xxx location=bom protocol=http2
+```
+
+**No "Unable to reach the origin service" errors!**
+
+## Test the Connection
+
+### From outside Docker (your current working test):
+```bash
+curl 172.18.0.1:9090
+# Should return: Monaco Code Execution Server v1.0.0
+```
+
+### From the tunnel (once running):
+```bash
+# Test via the public URL
+curl https://api.ishikabhoyar.tech
+```
+
+## Troubleshooting
+
+### If Solution 1 still doesn't work:
+1. Check if Docker bridge IP changed:
+   ```bash
+   docker network inspect bridge | grep Gateway
+   ```
+2. Update `config.tunnel-only.json` with the correct IP
+
+### If Solution 2 doesn't work:
+- Host network mode may not be fully supported on your OS
+- Fall back to Solution 1 with correct bridge IP
+
+### Check tunnel logs:
+```bash
+docker-compose -f docker-compose.tunnel-only.yml logs -f
+```
+
+### Verify backend is accessible from Docker:
+```bash
+docker run --rm alpine/curl:latest curl http://172.18.0.1:9090
+```
+
+## Summary
+
+**Current Status:** ✅ Config updated to use `172.18.0.1:9090`
+
+**Next Step:** Rebuild and restart the tunnel:
+```bash
+docker-compose -f docker-compose.tunnel-only.yml down
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+The tunnel should now successfully connect to your backend! 🎉

+# Quick Start - Tunnel Only Mode
+
+## What This Does
+- Runs **only** the Cloudflare tunnel in Docker
+- Your backend runs **outside Docker** on port 9090
+- Tunnel forwards traffic from `api.ishikabhoyar.tech` to your local backend
+
+## Quick Start
+
+### Step 1: Start your backend on port 9090
+```bash
+PORT=9090 go run main.go
+```
+
+### Step 2: Start the tunnel
+
+**Windows (PowerShell):**
+```powershell
+.\start-tunnel-only.ps1
+```
+
+**Linux/Mac:**
+```bash
+chmod +x start-tunnel-only.sh
+./start-tunnel-only.sh
+```
+
+**Or manually:**
+```bash
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+## Files Created
+
+1. **Dockerfile.tunnel-only** - Lightweight Docker image with only cloudflared
+2. **docker-compose.tunnel-only.yml** - Docker Compose config for tunnel only
+3. **config.tunnel-only.json** - Cloudflare tunnel config pointing to port 9090
+4. **start-tunnel-only.ps1** - PowerShell helper script
+5. **start-tunnel-only.sh** - Bash helper script
+6. **README.tunnel-only.md** - Detailed documentation
+
+## Test It
+
+1. Start backend: `PORT=9090 go run main.go`
+2. Start tunnel: `docker-compose -f docker-compose.tunnel-only.yml up --build`
+3. Test: `curl https://api.ishikabhoyar.tech`
+
+## Stop
+
+```bash
+docker-compose -f docker-compose.tunnel-only.yml down
+```
+
+## Troubleshooting
+
+**Backend not reachable?**
+- Check backend is running: `curl http://localhost:9090`
+- Check tunnel logs: `docker-compose -f docker-compose.tunnel-only.yml logs -f`
+
+**Tunnel not connecting?**
+- Verify credentials.json and cert.pem are valid
+- Check Cloudflare dashboard
+
+## Original Files (Unchanged)
+
+The original tunnel setup files are still available:
+- `Dockerfile.tunnel` - Backend + Tunnel in one container
+- `docker-compose.tunnel.yml` - Original compose file
+- These files still point to port 8080
