Worked on security hardening and build reliability for the Fabric repository by enhancing its Dockerfile. Focused on containerization and DevOps practices, the work involved pinning Alpine 3.21 and Go 1.25.9 versions to ensure consistent, reproducible builds. Introduced a multi-stage Docker build that installs the Go toolchain only in the builder stage, minimizing the final image’s attack surface. The final container was configured to run as a non-root user, improving compliance and safety. Applied CVE fixes, updated setuptools, and adjusted the yt-dlp path to further strengthen security and reliability, all implemented using Dockerfile and related container technologies.
