# Foxhunt Docker Infrastructure

## Overview
Simplified Docker setup for the Foxhunt monolithic HFT trading system. Only databases and monitoring run in Docker - the main application runs on the host for maximum performance.

## Services

### Core Infrastructure (Docker)
- **PostgreSQL**: Main database for trades, orders, positions
- **Redis**: Cache and pub/sub for real-time data
- **InfluxDB**: Time-series database for market data
- **Prometheus**: Metrics collection and monitoring

### Application (Host)
The Foxhunt monolithic application runs directly on the host machine for:
- Sub-50μs latency requirements
- Direct hardware access (RDTSC timing, SIMD)
- GPU acceleration for ML models
- Zero container overhead

## Quick Start

1. **Setup environment**:
```bash
cp .env.example .env
# Edit .env with your passwords
```

2. **Start infrastructure**:
```bash
docker-compose up -d
```

3. **Run the application**:
```bash
# From project root
cargo run --release
```

## Connection URLs

When running on the same host:
- PostgreSQL: `localhost:5432`
- Redis: `localhost:6379`
- InfluxDB: `http://localhost:8086`
- Prometheus: `http://localhost:9090`

## Architecture Changes

**Before (Microservices)**:
- 6 service containers (trading-engine, risk-management, etc.)
- Consul for service discovery
- Jaeger for distributed tracing
- Complex orchestration

**After (Monolithic)**:
- Single high-performance application on host
- Only databases in Docker
- Direct connections, no service mesh
- 80% reduction in Docker complexity
