Prerequisites

Required Software

• Python 3.11+
• PostgreSQL 15+

Local Development

1. Setup Virtual Environment

python -m venv venv
source venv/bin/activate  # Windows: venv\Scripts\activate
pip install -r requirements.txt

2. Configure Environment

cp .env.example .env
# Edit .env with your settings

3. Start Dependencies

# PostgreSQL
docker run -d -p 5432:5432 \
  -e POSTGRES_USER=blackroad \
  -e POSTGRES_PASSWORD=password \
  -e POSTGRES_DB=blackroad_db \
  postgres:15-alpine

# Redis
docker run -d -p 6379:6379 redis:7-alpine

4. Run Application

python run.py
# Or using uvicorn directly:
uvicorn app.main:app --reload --host 0.0.0.0 --port 8000

Access the API:

• API: http://localhost:8000
• Docs: http://localhost:8000/api/docs

Docker Deployment

Development

# Start all services
docker-compose up -d

# View logs
docker-compose logs -f backend

# Stop services
docker-compose down

Production Build

# Build production image
docker build -t blackroad-backend:production .

# Run with production settings
docker run -d \
  -p 8000:8000 \
  --env-file .env.production \
  --name blackroad-backend \
  blackroad-backend:production

Production Deployment

Security Checklist

• Generate strong SECRET_KEY: openssl rand -hex 32
• Set DEBUG=False
• Configure HTTPS/SSL
• Use strong database passwords
• Enable CORS only for trusted origins
• Set up firewall rules
• Enable rate limiting
• Configure logging

1. DigitalOcean Deployment

Using App Platform

# Create app.yaml
doctl apps create --spec .do/app.yaml

# Or use the web interface:
# 1. Connect GitHub repository
# 2. Configure environment variables
# 3. Deploy

Using Droplet

# Create droplet
doctl compute droplet create blackroad-backend \
  --image ubuntu-22-04-x64 \
  --size s-2vcpu-4gb \
  --region nyc1

# SSH into droplet
ssh root@your-droplet-ip

# Install dependencies
apt update && apt install -y docker.io docker-compose git

# Clone repository
git clone https://github.com/your-org/BlackRoad-Operating-System.git
cd BlackRoad-Operating-System/backend

# Configure environment
cp .env.example .env
nano .env  # Edit settings

# Deploy
docker-compose -f docker-compose.prod.yml up -d

2. AWS Deployment

Using ECS (Elastic Container Service)

# Build and push to ECR
aws ecr create-repository --repository-name blackroad-backend
docker tag blackroad-backend:latest \
  123456789012.dkr.ecr.us-east-1.amazonaws.com/blackroad-backend:latest
docker push 123456789012.dkr.ecr.us-east-1.amazonaws.com/blackroad-backend:latest

# Create ECS task definition and service
aws ecs create-cluster --cluster-name blackroad-cluster
# ... (see AWS ECS documentation for full setup)

Using EC2

# Launch EC2 instance (t3.medium recommended)
# SSH into instance
ssh -i your-key.pem ubuntu@ec2-instance-ip

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

# Deploy application
# ... (similar to DigitalOcean Droplet steps)

3. Google Cloud Platform

Using Cloud Run

# Build and push to Container Registry
gcloud builds submit --tag gcr.io/your-project/blackroad-backend

# Deploy to Cloud Run
gcloud run deploy blackroad-backend \
  --image gcr.io/your-project/blackroad-backend \
  --platform managed \
  --region us-central1 \
  --set-env-vars DATABASE_URL=... \
  --allow-unauthenticated

4. Heroku

# Login to Heroku
heroku login

# Create app
heroku create blackroad-backend

# Add PostgreSQL
heroku addons:create heroku-postgresql:hobby-dev

# Add Redis
heroku addons:create heroku-redis:hobby-dev

# Set environment variables
heroku config:set SECRET_KEY=your-secret-key
heroku config:set ENVIRONMENT=production

# Deploy
git push heroku main

# Scale
heroku ps:scale web=1

Database Migrations

Using Alembic

# Initialize Alembic (already done)
alembic init alembic

# Create migration
alembic revision --autogenerate -m "Add new table"

# Apply migrations
alembic upgrade head

# Rollback
alembic downgrade -1

Monitoring

Health Checks

# API health
curl http://your-domain.com/health

# Expected response:
# {"status": "healthy", "timestamp": 1234567890}

Logging

# Configure logging in production
import logging

logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
    handlers=[
        logging.FileHandler('/var/log/blackroad/app.log'),
        logging.StreamHandler()
    ]
)

Monitoring Tools

• Prometheus: Metrics collection
• Grafana: Metrics visualization
• Sentry: Error tracking
• New Relic: APM
• Datadog: Full-stack monitoring

Performance Optimization

Database

# Add indexes to frequently queried columns
# In your models:
class User(Base):
    __tablename__ = "users"

    id = Column(Integer, primary_key=True, index=True)
    username = Column(String(50), unique=True, index=True)
    email = Column(String(255), unique=True, index=True)

Caching

# Implement Redis caching
from app.redis_client import get_redis

async def get_cached_data(key: str):
    redis = await get_redis()
    cached = await redis.get(key)
    if cached:
        return json.loads(cached)
    return None

Rate Limiting

# Add to main.py
from slowapi import Limiter, _rate_limit_exceeded_handler
from slowapi.util import get_remote_address

limiter = Limiter(key_func=get_remote_address)
app.state.limiter = limiter
app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)

Backup and Recovery

Database Backups

# Automated PostgreSQL backups
# Add to crontab:
0 2 * * * pg_dump -U blackroad blackroad_db > /backups/db_$(date +\%Y\%m\%d).sql

# Restore from backup
psql -U blackroad blackroad_db < /backups/db_20231215.sql

File Storage Backups

# Sync to S3
aws s3 sync /var/lib/blackroad/files s3://blackroad-backups/files

Troubleshooting

Common Issues

Database Connection Issues

# Check PostgreSQL is running
docker ps | grep postgres

# Check connection
psql -U blackroad -h localhost -d blackroad_db

Redis Connection Issues

# Check Redis is running
docker ps | grep redis

# Test connection
redis-cli ping

High Memory Usage

# Check container stats
docker stats

# Adjust worker processes
uvicorn app.main:app --workers 2 --limit-concurrency 100

Debugging

# View logs
docker-compose logs -f backend

# Enter container
docker exec -it blackroad_backend bash

# Check database
docker exec -it blackroad_postgres psql -U blackroad -d blackroad_db
