Contributed to the astronomer/astronomer-cosmos repository by implementing ProfileConfig support in the DbtDockerBaseOperator, enabling TaskGroup usage with Docker operators for more modular and scalable Airflow DAGs. This work involved extending the operator to accept profile configurations, which allows for improved resource utilization and flexibility in orchestrating Docker-based tasks. The developer also expanded and integrated Docker-related tests within the CI pipeline, specifically updating tests in tests/test_converter.py to validate the new functionality and guard against regressions. The project leveraged Python, Docker, and CI/CD practices, demonstrating a focused approach to enhancing operator capabilities and ensuring robust automated testing.
