- Removed the iat.yaml configuration file to simplify the container setup and reduce complexity.
- Adjusted the exposed port to 80, aligning with standard HTTP practices for the scraper application.
- Updated the CI configuration in .drone.yml to reflect these changes, ensuring a streamlined build process.
