Worked on enhancing container security for the geosolutions-it/MapStore2 repository by implementing a feature that ensures containers run as non-root users. This involved updating the main Dockerfile to create and utilize a dedicated non-root user and group, as well as modifying the PostgreSQL Dockerfile to operate under the default 'postgres' user. The approach aligned with security best practices, reducing the risk associated with potential container compromises. The work leveraged DevOps methodologies and focused on Docker and security principles, with all changes delivered through a single feature update and no bug fixes during the period, demonstrating targeted and effective engineering.
