+- `./db_data`: PostgreSQL database data
+
+#### 5.5 Docker Troubleshooting
+
+**Common issues and solutions**:
+
+1. **Port conflicts**
+```bash
+# Check port usage
+netstat -tulpn | grep :5000
+# Or modify port mapping in docker-compose.yml
+```
+
+2. **Insufficient memory**
+```bash
+# Increase Docker memory limits
+# Adjust resource allocation in Docker Desktop
+```
+
+3. **Permission issues**
+```bash
+# Ensure scripts have execute permissions
+chmod +x scripts/*.sh
+
+# Ensure data directory permissions are correct
+sudo chown -R $USER:$USER ./
+```
+
+4. **Build failures**
+```bash
+# Clear Docker cache and rebuild
+docker system prune -a
+docker-compose build --no-cache
+```
+
+5. **Service won't start**
+```bash
+# Check logs to troubleshoot
+docker-compose logs bettafish
+
+# Check environment variable configuration
+docker-compose config
+```
