Worked on stabilizing Docker-out-of-Docker (DooD) builds for the sonic-net/sonic-buildimage repository by correcting the startup logic and removing host daemon management from within the container. Refactored the Makefile’s docker-start target to use explicit if/else statements, ensuring correct handling for both DooD with native dockerd and standard build scenarios. This approach reduced build failures related to DooD, improved the reliability of containerized build pipelines, and accelerated CI feedback. Leveraged skills in containerization, DevOps, and Docker to validate behavior across configurations, focusing on robust startup checks and maintaining clear separation between container and host responsibilities during builds.
