Contributed to the astronomer/airflow repository by enhancing the DockerOperator to support auto_remove='force' during task termination, addressing the issue of orphaned containers when jobs are killed. This work involved extending the operator’s on_kill logic, integrating robust error handling for Docker API interactions, and developing comprehensive unit and integration tests to ensure reliability. Leveraging Python and Docker, the developer focused on improving resource hygiene and the stability of Docker-based Airflow workflows. The changes resulted in safer task termination and reduced resource leakage, demonstrating a methodical approach to back end development, API integration, and automated testing within a production workflow.
