During the month, contributed a Docker Compose integration for the Rooms service within the pucrs-constrsw-2025-2/base repository. This work involved authoring a YAML-based configuration that builds the service from a local Dockerfile, sets up environment variables such as the database URL, and manages networking, port mappings, and automatic restarts. A health check was included to ensure reliable service startup. The approach focused on enabling repeatable local development and streamlined onboarding by allowing the Rooms service to be spun up in isolation. Skills demonstrated included DevOps practices, container orchestration with Docker Compose, and environment management using Docker and YAML.
