Deployment Steps

1. Push to Repository 

git add .
git commit -m "Fix HF Space deployment: dependencies, port config, error handling"
git push origin main

2. HuggingFace Space Configuration

Space Settings:

  • SDK: Docker
  • Port: 7860 (auto-configured)
  • Entry Point: Defined in Dockerfile CMD
  • Memory: 2GB recommended (512MB minimum)

Optional Environment Variables:

# Core (usually not needed - auto-configured)
PORT=7860
HOST=0.0.0.0
PYTHONUNBUFFERED=1

# Optional API Keys (graceful degradation if missing)
HF_TOKEN=your_hf_token_here
BINANCE_API_KEY=optional
COINGECKO_API_KEY=optional

3. Monitor Deployment

Watch HF Space logs for:

✅ "Starting HuggingFace Unified Server..."
✅ "PORT: 7860"
✅ "Static dir exists: True"
✅ "All 28 routers loaded"
✅ "Application startup complete"
✅ "Uvicorn running on http://0.0.0.0:7860"

Post-Deployment Tests

Test 1: Health Check 

curl https://[space-name].hf.space/api/health
# Expected: {"status":"healthy","timestamp":"...","service":"unified_query_service","version":"1.0.0"}

Test 2: Dashboard Access 

curl -I https://[space-name].hf.space/
# Expected: HTTP 200 or 307 (redirect to dashboard)

Test 3: Static Files 

curl -I https://[space-name].hf.space/static/pages/dashboard/index.html
# Expected: HTTP 200, Content-Type: text/html

Test 4: API Docs 

curl https://[space-name].hf.space/docs
# Expected: HTML page with Swagger UI

Test 5: Market Data 

curl https://[space-name].hf.space/api/market
# Expected: JSON with market data

Expected Performance

Startup Time

  • Cold Start: 15-30 seconds
  • Warm Start: 5-10 seconds

Memory Usage

  • Initial: 300-400MB
  • Peak: 500-700MB
  • With Heavy Load: 800MB-1GB

Response Times

  • Health Check: < 50ms
  • Static Files: < 100ms
  • API Endpoints: 100-500ms
  • External API Calls: 500-2000ms

Troubleshooting Guide

Issue: "Port already in use"

Solution: HF Space manages ports automatically. No action needed.

Issue: "Module not found" errors

Solution: Check requirements.txt is complete and correctly formatted.

pip install -r requirements.txt
python3 -c "from hf_unified_server import app"

Issue: "Background worker failed"

Solution: Non-critical. Server continues without it. Check logs for details.

Issue: "Static files not loading"

Solution: Verify static/ directory exists and is included in Docker image.

ls -la static/pages/dashboard/index.html

Issue: High memory usage

Solution:

  1. Check if torch is installed (optional, remove to save 2GB)
  2. Reduce concurrent connections
  3. Increase HF Space memory allocation

Rollback Procedure

If deployment fails:

Option 1: Revert to Previous Commit 

git revert HEAD
git push origin main

Option 2: Use Minimal App

Change Dockerfile CMD to:

CMD ["python", "-m", "uvicorn", "app:app", "--host", "0.0.0.0", "--port", "7860"]

Option 3: Emergency Fix

Create minimal emergency_app.py:

from fastapi import FastAPI
app = FastAPI()

@app.get("/")
def root():
    return {"status": "emergency_mode"}

@app.get("/api/health")
def health():
    return {"status": "healthy", "mode": "emergency"}

Success Criteria

Must Have (Critical)

  • Server starts without errors
  • Port 7860 binding successful
  • Health endpoint responds
  • Static files accessible
  • At least 20/28 routers loaded

Should Have (Important)

  • All 28 routers loaded
  • Background worker running
  • Resources monitor active
  • API documentation accessible

Nice to Have (Optional)

  • AI model inference (fallback to HF API)
  • Real-time monitoring dashboard
  • WebSocket endpoints

Monitoring & Maintenance

Health Checks

Set up periodic checks:

*/5 * * * * curl https://[space-name].hf.space/api/health

Log Monitoring

Watch for:

  • ⚠️ Warnings about disabled services (acceptable)
  • ❌ Errors in router loading (investigate)
  • 🔴 Memory alerts (upgrade Space tier if needed)

Performance Monitoring

Track:

  • Response times (/api/status)
  • Error rates (check HF Space logs)
  • Memory usage (HF Space dashboard)

Documentation Links

  • API Docs: https://[space-name].hf.space/docs
  • Dashboard: https://[space-name].hf.space/
  • Health Check: https://[space-name].hf.space/api/health
  • System Monitor: https://[space-name].hf.space/system-monitor

Support & Debugging

Enable Debug Logging

Set environment variable:

DEBUG=true

View Startup Diagnostics

Check HF Space logs for:

📊 STARTUP DIAGNOSTICS:
   PORT: 7860
   HOST: 0.0.0.0
   Static dir exists: True
   ...

Common Warning Messages (Safe to Ignore) 

⚠️  Torch not available. Direct model loading will be disabled.
⚠️  Transformers library not available.
⚠️  Resources monitor disabled: [reason]
⚠️  Background worker disabled: [reason]

These warnings indicate optional features are disabled but core functionality works.
