## 📦 Quick Start



### Prerequisites

- Docker and Docker Compose installed

- Git (for cloning the repository)



### Installation



1. **Clone the repository**:

   ```bash

   git clone 

   cd DockMaster

   ```



2. **Start the application**:

   ```bash

   ./docker-start.sh

   ```



3. **Access the application**:

   - Frontend: http://localhost:4000

   - Backend API: http://localhost:9090



4. **Login with default credentials**:

   - Username: `admin`

   - Password: `admin123`

   - **⚠️ Change the password immediately after first login!**



## ⚙️ Configuration



### Environment Variables



The application supports flexible configuration through environment variables in the `.env` file:



```bash

# Backend Configuration

BACKEND_PORT=9090

JWT_SECRET=your-super-secret-jwt-key-change-this-in-production

ADMIN_USERNAME=admin

ADMIN_PASSWORD=admin123

LOG_LEVEL=info



# Frontend Configuration  

FRONTEND_PORT=4000

REACT_APP_API_URL=http://localhost:9090



# Database Configuration

DB_PATH=./data/dockmaster.db



# CORS Configuration

FRONTEND_URL=http://localhost:4000

```



### Changing Ports

To run on different ports, simply edit the `.env` file:

```bash

BACKEND_PORT=8080

FRONTEND_PORT=3000

REACT_APP_API_URL=http://localhost:8080

FRONTEND_URL=http://localhost:3000

```



Then restart the application:

```bash

./docker-stop.sh

./docker-start.sh

```



## 🔧 Management Commands



### Docker Compose Commands

```bash

# Start the application

./docker-start.sh



# Stop the application

./docker-stop.sh



# Test all functionality

./test_complete.sh



# View logs

docker logs dockmaster-backend

docker logs dockmaster-frontend



# Manual Docker Compose commands

docker-compose up -d          # Start services

docker-compose down           # Stop services

docker-compose logs -f        # Follow logs

docker-compose restart        # Restart services

```

## 🚨 Troubleshooting



### Common Issues



1. **Port Already in Use**:

   ```bash

   # Kill processes on ports

   lsof -ti:9090 | xargs kill -9

   lsof -ti:4000 | xargs kill -9

   ```



2. **Docker Socket Permission**:

   ```bash

   # Add user to docker group

   sudo usermod -aG docker $USER

   # Restart session

   ```



3. **Database Issues**:

   ```bash

   # Remove database file to reset

   rm -f data/dockmaster.db

   ```



4. **Build Issues**:

   ```bash

   # Clean Docker build cache

   docker system prune -a

   ```



### Logs and Debugging

```bash

# View backend logs

docker logs dockmaster-backend -f



# View frontend logs

docker logs dockmaster-frontend -f



# Check container status

docker ps -a
