🐳 Docker One-Click Deployment Guide

This guide will help you quickly deploy the NOFX AI Trading Competition System using Docker.

📋 Prerequisites

Before you begin, ensure your system has:

• Docker: Version 20.10 or higher
• Docker Compose: Version 2.0 or higher

Installing Docker

macOS / Windows

Download and install Docker Desktop

Linux (Ubuntu/Debian)

# Install Docker
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

# Install Docker Compose
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

# Add current user to docker group
sudo usermod -aG docker $USER
newgrp docker

# Verify installation
docker --version
docker-compose --version

🚀 Quick Start (3 Steps)

Step 1: Prepare Configuration File

# Copy configuration template
cp config.json.example config.json

# Edit configuration file with your API keys
nano config.json  # or use any other editor

Required fields:

{
  "traders": [
    {
      "id": "my_trader",
      "name": "My AI Trader",
      "ai_model": "deepseek",
      "binance_api_key": "YOUR_BINANCE_API_KEY",       // ← Your Binance API Key
      "binance_secret_key": "YOUR_BINANCE_SECRET_KEY", // ← Your Binance Secret Key
      "deepseek_key": "YOUR_DEEPSEEK_API_KEY",         // ← Your DeepSeek API Key
      "initial_balance": 1000.0,
      "scan_interval_minutes": 3
    }
  ],
  "use_default_coins": true,
  "api_server_port": 8080
}

Step 2: One-Click Start

# Build and start all services (first run)
docker-compose up -d --build

# Subsequent starts (without rebuilding)
docker-compose up -d

Startup options:

• --build: Build Docker images (use on first run or after code updates)
• -d: Run in detached mode (background)

Step 3: Access the System

Once deployed, open your browser and visit:

• Web Interface: http://localhost:3000
• API Health Check: http://localhost:8080/health

📊 Service Management

View Running Status

# View all container status
docker-compose ps

# View service health status
docker-compose ps --format json | jq

View Logs

# View all service logs
docker-compose logs -f

# View backend logs only
docker-compose logs -f backend

# View frontend logs only
docker-compose logs -f frontend

# View last 100 lines
docker-compose logs --tail=100

Stop Services

# Stop all services (keep data)
docker-compose stop

# Stop and remove containers (keep data)
docker-compose down

# Stop and remove containers and volumes (clear all data)
docker-compose down -v

Restart Services

# Restart all services
docker-compose restart

# Restart backend only
docker-compose restart backend

# Restart frontend only
docker-compose restart frontend

Update Services

# Pull latest code
git pull

# Rebuild and restart
docker-compose up -d --build

🔧 Advanced Configuration

Change Ports

Edit docker-compose.yml to modify port mappings:

services:
  backend:
    ports:
      - "8080:8080"  # Change to "your_port:8080"

  frontend:
    ports:
      - "3000:80"    # Change to "your_port:80"

Resource Limits

Add resource limits in docker-compose.yml:

services:
  backend:
    deploy:
      resources:
        limits:
          cpus: '2'
          memory: 2G
        reservations:
          cpus: '1'
          memory: 1G

Environment Variables

Create .env file to manage environment variables:

# .env
TZ=Asia/Shanghai
BACKEND_PORT=8080
FRONTEND_PORT=3000

Then use in docker-compose.yml:

services:
  backend:
    ports:
      - "${BACKEND_PORT}:8080"

📁 Data Persistence

The system automatically persists data to local directories:

• ./decision_logs/: AI decision logs
• ./coin_pool_cache/: Coin pool cache
• ./config.json: Configuration file (mounted)

Data locations:

# View data directories
ls -la decision_logs/
ls -la coin_pool_cache/

# Backup data
tar -czf backup_$(date +%Y%m%d).tar.gz decision_logs/ coin_pool_cache/ config.json

# Restore data
tar -xzf backup_20241029.tar.gz

🐛 Troubleshooting

Container Won't Start

# View detailed error messages
docker-compose logs backend
docker-compose logs frontend

# Check container status
docker-compose ps -a

# Rebuild (clear cache)
docker-compose build --no-cache

Port Already in Use

# Find process using the port
lsof -i :8080  # backend port
lsof -i :3000  # frontend port

# Kill the process
kill -9 <PID>

Configuration File Not Found

# Ensure config.json exists
ls -la config.json

# If not exists, copy template
cp config.json.example config.json

Health Check Failing

# Check health status
docker inspect nofx-backend | jq '.[0].State.Health'
docker inspect nofx-frontend | jq '.[0].State.Health'

# Manually test health endpoints
curl http://localhost:8080/health
curl http://localhost:3000/health

Frontend Can't Connect to Backend

# Check network connectivity
docker-compose exec frontend ping backend

# Check if backend service is running
docker-compose exec frontend wget -O- http://backend:8080/health

Clean Docker Resources

# Clean unused images
docker image prune -a

# Clean unused volumes
docker volume prune

# Clean all unused resources (use with caution)
docker system prune -a --volumes

🔐 Security Recommendations

1. Don't commit config.json to Git

   # Ensure config.json is in .gitignore
   echo "config.json" >> .gitignore
   

2. Use environment variables for sensitive data

   # docker-compose.yml
   services:
     backend:
       environment:
         - BINANCE_API_KEY=${BINANCE_API_KEY}
         - BINANCE_SECRET_KEY=${BINANCE_SECRET_KEY}
   

3. Restrict API access

   # Only allow local access
   services:
     backend:
       ports:
         - "127.0.0.1:8080:8080"
   

4. Regularly update images

   docker-compose pull
   docker-compose up -d
   

🌐 Production Deployment

Using Nginx Reverse Proxy

# /etc/nginx/sites-available/nofx
server {
    listen 80;
    server_name your-domain.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }

    location /api/ {
        proxy_pass http://localhost:8080/api/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Configure HTTPS (Let's Encrypt)

# Install Certbot
sudo apt-get install certbot python3-certbot-nginx

# Get SSL certificate
sudo certbot --nginx -d your-domain.com

# Auto-renewal
sudo certbot renew --dry-run

Using Docker Swarm (Cluster Deployment)

# Initialize Swarm
docker swarm init

# Deploy stack
docker stack deploy -c docker-compose.yml nofx

# View service status
docker stack services nofx

# Scale services
docker service scale nofx_backend=3

📈 Monitoring & Logging

Log Management

# Configure log rotation (already configured in docker-compose.yml)
logging:
  driver: "json-file"
  options:
    max-size: "10m"
    max-file: "3"

# View log statistics
docker-compose logs --timestamps | wc -l

Monitoring Tool Integration

Integrate Prometheus + Grafana for monitoring:

# docker-compose.yml (add monitoring services)
services:
  prometheus:
    image: prom/prometheus
    ports:
      - "9090:9090"
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml

  grafana:
    image: grafana/grafana
    ports:
      - "3001:3000"
