FauxDB Docker Setup

Complete guide to deploying FauxDB MongoDB-compatible database using Docker and Docker Compose

Prerequisites

Docker Requirements

  • Docker 20.10+ installed
  • Docker Compose 2.0+
  • 2GB+ RAM available
  • 5GB+ disk space
  • Ports 27018, 5432, 9090 available

System Requirements

  • Linux, macOS, or Windows with WSL2
  • Multi-core CPU recommended
  • SSD storage for better performance
  • Network access for MongoDB clients

Quick Start

1. Clone and Setup

# Clone the repository
git clone https://github.com/fauxdb/fauxdb.git
cd fauxdb
# Copy environment configuration
cp docker/config/docker.env.example .env
# Edit configuration (optional)
nano .env

2. Start FauxDB

# Quick setup and start
make setup
docker-compose up -d
# Check service status
docker-compose ps
# View logs
docker-compose logs -f fauxdb

3. Test MongoDB Connection

# Connect with mongosh
mongosh mongodb://localhost:27018
# Test basic operations
use testdb
db.runCommand({ping: 1})
db.test.insertOne({message: "Hello FauxDB!"})
db.test.find()

Development Environment

Hot Reload Development

# Start development environment
make dev
# View development logs
make dev-logs
# Open shell in container
make dev-shell
# Stop development environment
make dev-stop

Production Environment

# Start production environment
make prod
# Start with monitoring stack
make monitor
# View production logs
make prod-logs

Testing & Validation

Run Test Suite

# Run tests with Docker
make test
# Test with mongosh client
make test-mongosh
# Run performance tests
make perf-test

Database Operations

# Open PostgreSQL shell
make db-shell
# Backup database
make db-backup
# Restore database
make db-restore

Monitoring Setup

Prometheus Metrics

# Access metrics endpoint
curl http://localhost:9090/metrics
# Key metrics:
# - fauxdb_operations_total
# - fauxdb_operation_duration_seconds
# - fauxdb_connections_active
# - fauxdb_transactions_total

Health Checks

# Basic health check
curl http://localhost:9090/health
# Detailed status
curl http://localhost:9090/status
# Database connectivity
curl http://localhost:9090/db/health

Production Considerations

Security

  • • Use strong passwords and secrets
  • • Enable SSL/TLS for all communications
  • • Use Docker secrets for sensitive data
  • • Implement network segmentation
  • • Regular security updates
  • • Enable authentication and authorization

Performance

  • • Use SSD storage for data volumes
  • • Allocate sufficient CPU and memory
  • • Configure PostgreSQL parameters
  • • Monitor resource usage
  • • Use connection pooling
  • • Implement caching strategies

High Availability

  • • Deploy across multiple hosts
  • • Use Docker Swarm or Kubernetes
  • • Implement health checks
  • • Configure restart policies
  • • Set up automated backups
  • • Monitor service health

Backup & Recovery

  • • Automated daily backups
  • • Point-in-time recovery
  • • Cross-region replication
  • • Test restore procedures
  • • Backup verification
  • • Disaster recovery plan

Troubleshooting

Common Issues

Container won't start

# Check logs
docker-compose logs fauxdb
# Check port conflicts
netstat -tulpn | grep :27018

Database connection failed

# Check PostgreSQL status
docker-compose exec postgres psql -U postgres -c "SELECT version();"
# Check connection string
docker-compose exec fauxdb env | grep DATABASE_URL

MongoDB client can't connect

# Test connection
mongosh mongodb://localhost:27018 --eval "db.runCommand({ping: 1})"
# Check FauxDB status
curl http://localhost:9090/health
