Worked on the Loongson-Cloud-Community/docker-library repository to deliver cross-OS, multi-version OpenJDK support, enabling consistent deployments across AnolisOS, Debian, and OpenEuler. Developed and versioned Dockerfiles and Makefiles to automate the building and management of OpenJDK images for versions 8, 11, 17, 21, and 23. Standardized installation and verification workflows ensured reliable JDK availability in all images, supporting robust CI/CD pipelines. The approach focused on build automation and containerization using Docker, with clear documentation and reproducible processes. This work provided a foundation for scalable, multi-platform Java environments, addressing the need for uniformity in enterprise deployment scenarios.
