Deployment Workflow

Manual Deployment

# Trigger via Gitea UI
1. Go to Actions tab
2. Click "Deploy" workflow
3. Click "Run workflow"
4. Deployment will execute

Automatic Deployment

• Trigger: Push to main branch
• Flow:
  1. CI pipeline runs (tests, build validation)
  2. If CI passes: Deploy pipeline triggers
  3. App publishes to production
  4. Database migrations run
  5. Service restarts
  6. Health check verifies deployment

---

Verification

Post-Deployment Checklist

# 1. Check service status
sudo systemctl status kartsell

# 2. Check logs
sudo journalctl -u kartsell -f

# 3. Health check
curl https://kartsell.taxbaik.com/health

# 4. Check API
curl https://kartsell.taxbaik.com/api/status

# 5. Verify database
psql -h <db-host> -U kartsell -d kartsell -c "SELECT version();"

Rollback Procedure

# If deployment fails, rollback to previous version
cd /app/kartsell

# Keep previous release
cp -r . ../kartsell.backup-$(date +%s)

# Restore from git tag
git checkout <previous-tag>
dotnet publish -c Release -o publish

Gate 5: Shadow Run Monitoring

During deployment, Gate 5 validation runs automatically:

• 252+ trading days of historical backtesting
• Out-of-sample testing (OOS)
• Probability of backtest overfitting (PBO)
• Sharpe ratio validation

Status: Monitor via SSH tunnel to database.

Support & Troubleshooting

Common Issues

Issue	Solution
Connection refused	Check service status: sudo systemctl status kartsell
Database connection error	Verify SSH tunnel: ssh -L 5432:db:5432 user@host
Deployment timeout	Increase timeout in deploy.yml, check server disk space
API returns 503	Service may be restarting, wait 30 seconds

Getting Help
