Worked on the jhipster/generator-jhipster repository to modernize its infrastructure by upgrading the Docker base image from Java 17 to Java 21. Focused on containerization and DevOps practices, the work aimed to improve compatibility and prepare the project for upcoming Java 21 adoption. The technical approach involved updating Dockerfile configurations to ensure seamless integration with the new Java runtime while maintaining stability for downstream projects. Collaboration was emphasized through co-authorship of a critical infrastructure change, enhancing traceability and teamwork. The effort centered on maintainability and alignment with repository goals, enabling future support for Java 21 across the generator’s ecosystem.
