📦 One-Command Setup

Clone the repository
git clone https://github.com/yourusername/ai-learning-platform.git
cd ai-learning-platform

docker-compose up --build -d
docker-compose exec backend python seed_data.py

That's it! The setup script will:

Create environment files
Build Docker containers
Initialize the database
Seed sample data
Start all services

🌐 Access Your Application

After setup completes, open your browser:

Frontend: http://localhost:3000
Backend API: http://localhost:8000
API Documentation: http://localhost:8000/docs

🔑 Default Login Accounts

Role	Username	Password	Capabilities
Admin	`admin`	`admin123`	Full platform access, user management
User	`testuser`	`test123`	Create prompts, view learning history

⚠️ Security Note: Change these passwords immediately in production!

🔧 Manual Docker Setup

If the automated setup doesn't work, run manually:

Step 1: Environment Configuration

# Copy environment templates
cp backend/.env.example backend/.env
cp frontend/.env.example frontend/.env

# Edit backend/.env (optional - works with defaults)
nano backend/.env

Step 2: Build and Start Services

# Build and start all containers
docker-compose up --build -d

# Check if services are running
docker-compose ps

Step 3: Initialize Database

# Create database tables
docker-compose exec backend python init_db.py

# Seed categories and users
docker-compose exec backend python seed_data.py

🐳 Docker Services

The application runs in 3 containers:

⚙️ Configuration Options

Environment Variables

Backend Configuration (backend/.env):

# Database (auto-configured for Docker)
DATABASE_URL=postgresql://postgres:password@db:5432/learning_platform

# OpenAI API (optional)
OPENAI_API_KEY=your-openai-api-key-here

# JWT Security
SECRET_KEY=your-very-secure-secret-key-min-32-chars

# API Settings
API_HOST=0.0.0.0
API_PORT=8000
DEBUG=true

Frontend Configuration (frontend/.env):

# Backend API connection (auto-configured for Docker)
REACT_APP_API_URL=http://localhost:8000

OpenAI Integration (Optional)

To enable real AI responses:

Get an API key from OpenAI Platform

Edit backend/.env:

OPENAI_API_KEY=sk-your-actual-api-key-here

Restart backend:
```
docker-compose restart backend
```

Without OpenAI: The app works perfectly with intelligent mock responses!

🔍 Health Checks & Monitoring

Service Health

# Check all services
docker-compose ps

# Backend health endpoint
curl http://localhost:8000/health

# Frontend availability
curl http://localhost:3000

Logs & Debugging

# Follow all logs
docker-compose logs -f

# Backend application logs
docker-compose logs -f backend

# Database connection logs
docker-compose logs -f db

# Frontend build/runtime logs
docker-compose logs -f frontend

🛠️ Development with Docker

Hot Reload Development

Both frontend and backend support hot reload in Docker:

# Start in development mode (default)
docker-compose up -d

# Backend changes auto-reload (FastAPI --reload)
# Frontend changes auto-reload (React dev server)

Making Code Changes

Edit files locally
Changes automatically sync to containers via volumes
Services automatically restart/reload
Refresh browser to see changes

Adding Dependencies

Backend (Python):

# Add to requirements.txt
echo "new-package==1.0.0" >> backend/requirements.txt

# Rebuild backend container
docker-compose build backend
docker-compose restart backend

Frontend (Node.js):

# Add package via container
docker-compose exec frontend npm install new-package

# Or rebuild container
docker-compose build frontend
docker-compose restart frontend

🚀 Production Deployment

Production Docker Setup

# Use production compose file
docker-compose -f docker-compose.prod.yml up --build -d

# Or override environment
ENVIRONMENT=production docker-compose up -d

Environment Security

# Generate secure JWT secret
openssl rand -hex 32

# Use strong database passwords
DATABASE_URL=postgresql://user:strongpassword@db:5432/dbname

🐛 Troubleshooting

Port Conflicts

# Check what's using ports 3000, 8000, 5432
sudo lsof -i :3000
sudo lsof -i :8000
sudo lsof -i :5432

# Stop conflicting services or change ports in docker-compose.yml

Container Issues

# Remove all containers and rebuild
docker-compose down -v
docker-compose up --build -d

# Check container resource usage
docker stats

# View detailed container info
docker-compose logs --details backend

Database Problems

# Reset database completely
docker-compose down -v  # This removes the volume!
docker-compose up -d
docker-compose exec backend python init_db.py
docker-compose exec backend python seed_data.py

Common Solutions

# Permission issues on Linux
sudo chown -R $USER:$USER .

# Clear Docker cache
docker system prune -a

# Restart Docker daemon (Linux)
sudo systemctl restart docker

AI Generation Fails

# Check OpenAI API key
echo $OPENAI_API_KEY

# Check backend logs
docker-compose logs backend
