Worked on the rancher/cilium repository to deliver CI multi-architecture build support by updating the hubble-relay Dockerfile. Addressed the challenge of enabling arm64 builds on amd64 hosts by switching the build process to use the cilium-builder image, embedding all necessary tooling directly within the builder. This approach improved cross-architecture CI reliability and accelerated feedback for arm64 workloads. The work demonstrated proficiency in Docker, CI/CD pipelines, and Dockerfile optimization, focusing on maintainable build strategies. No major bugs were fixed during this period, with efforts concentrated on enhancing the CI process and supporting multi-arch development workflows for the project.
