Quick Start (Docker)

1. Start All Services

cd ~/mohawk-inference-engine
docker compose up -d

# Verify containers running
docker ps

Expected Output:

CONTAINER ID   IMAGE                        STATUS           PORTS
xxxxxxxxxx     mohawk-gui                  Up (healthy)     0.0.0.0:8003->8003/tcp
xxxxxxxxxx     mohawk-worker               Up (healthy)     0.0.0.0:8004->8003/tcp

2. Check Health

# GUI health
curl http://localhost:8003/health

# Worker health
curl http://localhost:8004/health

# Expected response:

3. List Available Models

curl http://localhost:8003/api/models

# Response:
# {
#   "models": [
#     {"name": "Llama-3-8B-Instruct-Q4_K_M", "size_gb": 7.2, ...},
#     {"name": "Mistral-7B-v0.3-Q5_K_M", "size_gb": 6.1, ...},

Troubleshooting

Containers Won't Start

# Check Docker daemon
docker ps

# View startup logs
docker compose logs

# Rebuild
docker compose down -v
docker compose up -d --build

Health Check Failing

# Test health endpoint directly
curl http://localhost:8003/health

# Check container logs
docker logs mohawk-gui

# Test network
docker network ls
docker network inspect mohawk-network

Port Conflict

# Check port usage
docker ps
lsof -i :8003  # macOS/Linux
netstat -ano | findstr :8003  # Windows

# Use different ports
docker run -p 9003:8003 ...

Out of Memory

# Check disk space
docker system df

# Prune
docker system prune -a

# Increase Docker memory
# Edit Docker Desktop settings

Next Steps

Load Real Models: Replace simulated responses with actual LLM
Add Database: Persist sessions/jobs (Redis, PostgreSQL)
Build GUI: Launch python mohawk_gui/main.py for desktop app
Scale Workers: Add more worker instances
Deploy: Move to Kubernetes or cloud (AWS, GCP, Azure)
Monitor: Set up metrics collection (Prometheus, Grafana)

Support

Docs: See LINUX_BUILD.md for platform-specific setup
Tests: Run test_user_functions.py for validation
Report: Check TEST_REPORT.md for detailed test results
Issues: Check Docker logs: docker compose logs -f
