Developed a foundational kernel-based containerization framework for the DragonOS-Community/DragonOS repository, focusing on system-level isolation and scalability. The work introduced PID, Mount, and User namespaces alongside a cgroups framework, enabling secure and reproducible container workloads. OverlayFS support was added to provide layered, non-destructive filesystems, while new kernel modules and filesystem types expanded containerization capabilities. The implementation, primarily in C and Makefile, emphasized maintainability and extensibility. Comprehensive documentation detailed the architecture, usage, and security considerations, ensuring clarity for future development. This cohesive feature established a robust base for containerized environments within DragonOS, addressing both isolation and operational reproducibility requirements.
October 2024: Delivered foundational kernel-based containerization framework with Namespaces and cgroups, including PID, Mount, and User namespaces, plus OverlayFS support for a layered filesystem. Implemented core kernel modules and new filesystem types, complemented by extensive documentation updates. This work lays the groundwork for isolated, scalable container workloads and enhances security and reproducibility for DragonOS deployments.
