Worked on stabilizing service accessibility in the pucrs-constrsw-2025-2/base repository by addressing a critical issue with Docker Compose port configuration. Focused on correcting the syntax for referencing environment variables within the docker-compose.yml file, ensuring that both internal and external API ports were properly exposed for deployment scenarios. Utilized Docker and YAML to implement and validate the fix, confirming that API endpoints remained reachable after the update. Contained the change within a single commit to minimize risk and simplify potential rollback. No new features were introduced during this period, with efforts concentrated on resolving this specific deployment bug.
