🐳 Docker Deployment

Docker Compose Services

services:
  blockchain:     # Ganache local blockchain
  backend:        # Node.js Express API
  nginx:          # Web server & reverse proxy

Docker Commands

# Start all services
docker-compose up -d

# View logs
docker-compose logs -f

# View specific service logs
docker-compose logs -f backend

# Check service status
docker-compose ps

# Restart service
docker-compose restart backend

# Stop all services
docker-compose down

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

# Remove all containers and volumes
docker-compose down -v

Docker Health Checks

# Check backend health
curl http://localhost:3000/health

curl https://localhost

# Check blockchain
curl -X POST http://localhost:9545 \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"net_version","params":[],"id":1}'

Production Deployment

# 1. Update .env for production
NODE_ENV=production
BLOCKCHAIN_PROVIDER=https://mainnet.infura.io/v3/YOUR_PROJECT_ID

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

# 3. Enable real SSL certificates
# Replace self-signed certs in ssl/ with Let's Encrypt

# 4. Configure domain
# Update nginx.conf with your domain

# 5. Enable firewall
ufw allow 80/tcp
ufw allow 443/tcp
ufw enable

🔧 Troubleshooting

Common Issues

1. "Cannot connect to blockchain"

# Check Ganache is running
docker-compose ps blockchain

# Restart blockchain
docker-compose restart blockchain

# Check network ID matches
# In truffle-config.js: networkId should match Ganache

2. "Contract not deployed"

# Deploy contracts
truffle migrate --network development --reset

# Update CONTRACT_ADDRESS in .env
# Get address from migration output

3. "MetaMask connection failed"

# 1. Add Ganache network to MetaMask:
Network Name: Ganache Local
RPC URL: http://localhost:9545
Chain ID: 5777
Currency: ETH

# 2. Import account from Ganache
# Use private key from Ganache output

# 3. Reset MetaMask account

4. "Document view shows 500 error"

# This means IPFS hash is mock (not real)
# Solution 1: Use mock detection (already implemented)
# Solution 2: Configure real IPFS
#   - Sign up at pinata.cloud
#   - Add API keys to .env
#   - Restart backend

5. "Authority login denied"

# Add your address as authority
node add-my-authority.js

# Or manually
node add-new-authority.js
# Enter your MetaMask address

6. "IPFS hash truncated"

# Fixed in latest version
# Hash length should be 46 characters
# Test: node tests/test-ipfs-hash-fix.js

7. "Backend won't start"

# Check logs
docker-compose logs backend

# Common fixes:
# - Port 3000 already in use
# - Missing .env file
# - Invalid CONTRACT_ADDRESS
# - Blockchain not accessible

# Restart with clean slate
docker-compose down -v
docker-compose up -d --build

8. "SSL certificate error"

# Accept self-signed certificate in browser
# Chrome: Click "Advanced" → "Proceed to localhost (unsafe)"
# Firefox: Click "Advanced" → "Accept the Risk and Continue"

# Or generate new certificates
openssl req -x509 -newkey rsa:4096 -keyout ssl/private.key \
  -out ssl/certificate.crt -days 365 -nodes

Debug Mode

# Enable debug logging
export DEBUG=*

# Start backend with debug
npm run dev

# Or in Docker
docker-compose logs -f backend

Health Check URLs

# Backend health
curl http://localhost:3000/health

# Blockchain connection
curl -X POST http://localhost:9545 \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

# Frontend
curl -k https://localhost
