During October 2025, Eduardo Wolf developed and delivered Docker Compose integration for the Rooms service in the pucrs-constrsw-2025-2/base repository. He built the service from a local Dockerfile, configuring environment variables such as the database URL, setting up network and port mappings, and implementing automatic restart and health checks to ensure reliable startup. Using Docker, Docker Compose, and YAML, Eduardo enabled repeatable local development and testing by allowing the Rooms service to be spun up in isolation. This work focused on feature delivery and environment stabilization, resulting in faster onboarding and more dependable deployments without major bug fixes.
