Application Services Testing Results

1. Trading Service ✅ SUCCESS

Image: foxhunt-trading-service:latest (119MB) Container: Started successfully Status: Fully operational

Startup Sequence

✅ ConfigManager initialized
✅ Database connection pool established
✅ Repository layer initialized
✅ Default configurations loaded
✅ Kill switch system initialized
✅ Emergency response monitoring started
✅ Unix socket kill switch active (/tmp/foxhunt/kill_switch.sock)
✅ Model cache initialized (<50μs inference capability)
✅ Configuration hot-reload monitoring started
✅ Authentication interceptor initialized (Tonic 0.14)
✅ Compliance service initialized (SOX, MiFID II audit trails)
✅ Rate limiter initialized (per-user, per-IP, global limits)
✅ gRPC server started with TLS and authentication

Service Endpoints

• gRPC: 0.0.0.0:50051 (listening)
• Health: http://0.0.0.0:8080 (active)
• Metrics: 0.0.0.0:9092 (configured)

Resource Usage

• Memory: 16.95 MiB (excellent - well under 500MB target)
• CPU: 0.00% (idle)
• Threads: 33

Configuration Requirements Met

• ✅ DATABASE_URL: Configured
• ✅ REDIS_URL: Configured
• ✅ VAULT_ADDR: Configured
• ✅ VAULT_TOKEN: Configured
• ✅ JWT_SECRET: Configured (64+ char requirement met)
• ⚠️ KILL_SWITCH_MASTER_TOKEN: Not set (fallback active - INSECURE for production)

Warnings (Non-Critical)

1. JWT secret loaded from environment variable (should use JWT_SECRET_FILE for production)
2. Kill switch master token not set (using insecure fallback)
3. Configuration monitoring stopped (expected behavior)

2. Backtesting Service ❌ FAILED

Image: foxhunt-backtesting-service:latest (120MB) Container: Started but exited with code 1 Status: Configuration error

Error Analysis

Error: Failed to create repositories
Caused by: Configuration error in field 'api_key': Benzinga API key is required

Root Cause

Missing required API key for Benzinga market data provider. Service requires BENZINGA_API_KEY environment variable.

Startup Progress Before Failure

✅ Configuration loaded from environment
✅ Backtesting configuration loaded
✅ Storage manager initialized with HFT optimizations
✅ ObjectStore S3 backend initialized (bucket: foxhunt-models, region: us-east-1)
✅ Model cache initialized with S3 storage
✅ Databento historical provider initialized
✅ Databento WebSocket client initialized
❌ Repository creation failed (missing Benzinga API key)

Required Fixes

1. Add BENZINGA_API_KEY environment variable
2. Potentially make Benzinga optional or provide mock/fallback provider

3. ML Training Service ❌ FAILED

Image: foxhunt-ml-training-service:latest (2.24GB) Container: Started but exited with code 2 Status: Command-line interface error

Error Analysis

Service expects a subcommand but none was provided. The entry point needs to be configured to run serve command by default.

CLI Output

ML Training Service for Foxhunt HFT Trading System

Usage: ml_training_service <COMMAND>

Commands:
  serve     Start the ML training service
  health    Health check
  database  Database operations
  config    Configuration validation
  help      Print this message or the help of the given subcommand(s)

Required Fixes

1. Update Dockerfile CMD to: ["ml_training_service", "serve"]
2. Or update docker-compose to add command override
3. Test GPU access after fixing command issue

4. API Gateway ❌ NOT TESTED

Image: foxhunt-api-gateway:latest (119MB) Container: Not started Status: Skipped (depends on all backend services)

Dependency Chain

API Gateway requires all backend services (Trading, Backtesting, ML Training) to be healthy before starting. Since Backtesting and ML Training failed, API Gateway was not tested.

Expected Startup Behavior

Based on docker-compose.yml, API Gateway:

1. Connects to Trading Service (http://trading_service:50051)
2. Connects to Backtesting Service (http://backtesting_service:50052)
3. Connects to ML Training Service (http://ml_training_service:50053)
4. Panics if any backend service connection fails

GPU Support Validation ⚠️ INCOMPLETE

Issue Identified

Docker images do not include NVIDIA runtime libraries (nvidia-smi not found in container PATH).

Test Attempted

docker exec foxhunt-trading-test nvidia-smi
# Result: executable file not found in $PATH

Required Fixes

1. Dockerfile Updates

Add NVIDIA CUDA runtime to production images:

FROM nvidia/cuda:12.2.0-runtime-ubuntu22.04 as runtime
# Install CUDA libraries for GPU inference

2. Docker Compose Configuration

Already configured correctly:

runtime: nvidia
environment:
  - NVIDIA_VISIBLE_DEVICES=all
  - NVIDIA_DRIVER_CAPABILITIES=compute,utility

3. Validation Commands

After fixing Dockerfiles, test with:

docker run --gpus all foxhunt-ml-training-service:latest nvidia-smi

Network and Port Configuration

Infrastructure Ports (Healthy)

• PostgreSQL: 5432 ✅
• Redis: 6379 ✅
• Vault: 8200 ✅
• InfluxDB: 8086 ✅
• Prometheus: 9090 ✅
• Grafana: 3000 ✅

Application Ports (Tested)

• Trading Service gRPC: 50052 → 50051 (internal) ✅
• Trading Service Metrics: 9092 ✅
• Backtesting Service gRPC: 50053 → 50052 (internal) ⚠️ Not tested (config error)
• ML Training Service gRPC: 50054 → 50053 (internal) ⚠️ Not tested (command error)
• API Gateway gRPC: 50051 → 50050 (internal) ⚠️ Not tested (dependency)

Port Conflicts Identified

  • Workaround: Mapped backtesting metrics to 9193 during testing

---

Configuration Discovery

Required Environment Variables (All Services)

Common Configuration

DATABASE_URL=postgresql://foxhunt:foxhunt_dev_password@postgres:5432/foxhunt
REDIS_URL=redis://redis:6379
VAULT_ADDR=http://vault:8200
VAULT_TOKEN=foxhunt-dev-root
RUST_LOG=info

Authentication (Trading, API Gateway)

JWT_SECRET=<64+ character base64 string>
# Generate with: openssl rand -base64 64
# Validation: Must contain uppercase, lowercase, numbers, symbols

API Keys (Backtesting)

BENZINGA_API_KEY=<required - currently missing>

Optional Security (Production)

KILL_SWITCH_MASTER_TOKEN=<recommended for production>
JWT_SECRET_FILE=/path/to/secret  # Alternative to JWT_SECRET env var

---

Dockerfile Issues Discovered

1. Path Resolution Error

Issue: docker-compose build attempts to copy crates/config but directory is config

Evidence:

Step 16/35 : COPY crates/config ./crates/config
COPY failed: file not found in build context or excluded by .dockerignore

Impact: Cannot rebuild images via docker-compose (workaround: use pre-built images)

Fix Required: Update all Dockerfiles

# Current (broken)
COPY crates/config ./crates/config

# Should be
COPY config ./config

2. ML Training Service Entry Point

Issue: Container expects subcommand but Dockerfile doesn't provide default

Fix Required:

# Add to ml_training_service/Dockerfile
CMD ["ml_training_service", "serve"]

3. Missing NVIDIA Runtime

Issue: GPU-enabled services don't include NVIDIA CUDA runtime

Fix Required:

# Change base image for GPU services
FROM nvidia/cuda:12.2.0-runtime-ubuntu22.04 as runtime

---

Resource Usage Analysis

Trading Service (Only Service Running)

• Memory: 16.95 MiB / 31.07 GiB (0.05% usage)
• CPU: 0.00% (idle)
• Network: 12.6 kB sent / 10.5 kB received
• Disk: 3.94 MB written / 0 read
• Threads: 33

Assessment

✅ EXCELLENT - Memory usage well under 500 MB target (only 17 MB) ✅ PASSED - No critical errors in logs ✅ PASSED - Clean startup sequence ✅ PASSED - All required subsystems initialized

---

Critical Blockers for Full Deployment

Priority 1 (BLOCKING)

1. Backtesting Service: Missing Benzinga API key
2. ML Training Service: Missing default serve command
3. Dockerfile Paths: crates/config → config correction

Priority 2 (PRODUCTION)

4. GPU Support: Add NVIDIA runtime to Dockerfiles
5. Security Tokens: KILL_SWITCH_MASTER_TOKEN configuration
6. JWT Secrets: Move to file-based secrets (JWT_SECRET_FILE)

Priority 3 (OPTIMIZATION)

7. Port Conflicts: Resolve Alertmanager port 9093 conflict
8. Health Probes: Install grpc_health_probe in containers
9. Metrics: Validate Prometheus scraping configuration

---

Recommendations for Production Deployment

1. Environment Configuration

Create environment-specific configuration files:

# .env.production
BENZINGA_API_KEY=<from_vault>
JWT_SECRET_FILE=/run/secrets/jwt_secret
KILL_SWITCH_MASTER_TOKEN_FILE=/run/secrets/kill_switch_token

2. Docker Compose Overrides

# docker-compose.prod.yml
services:
  ml_training_service:
    command: ["ml_training_service", "serve"]
    runtime: nvidia
    env_file:
      - .env.production

3. Health Check Integration

healthcheck:
  test: ["CMD", "/usr/local/bin/grpc_health_probe", "-addr=localhost:50051"]
  interval: 10s
  timeout: 5s
  start_period: 30s
  retries: 3

4. Security Hardening

• Use Docker secrets for sensitive data
• Enable mTLS for inter-service communication
• Implement network policies for service isolation
• Add resource limits (CPU, memory)
