## Troubleshooting

### Common Issues

**Issue**: Pod fails to start
```bash
# Check pod status
kubectl describe pod POD_NAME -n tracertm

# Check logs
kubectl logs POD_NAME -n tracertm
```

**Issue**: Database connection errors
```bash
# Test connection
kubectl exec -it POD_NAME -n tracertm -- \
  psql -h postgres -U tracertm -d tracertm

# Check credentials
kubectl get secret tracertm-secrets -n tracertm -o yaml
```

**Issue**: High memory usage
```bash
# Check resource usage
kubectl top pods -n tracertm

# Adjust limits
kubectl set resources deployment/tracertm-backend \
  --limits=memory=2Gi -n tracertm
```
