October 2025 monthly summary focused on delivering a Dockerized deployment pathway for the Lessons Service in the pucrs-constrsw-2025-2/base repo. Key work centered on implementing deployment infrastructure to enable reliable, docker-based runs of the new service with PostgreSQL backing. Key outcomes include: - Enables end-to-end deployment of the Lessons Service via Docker Compose, with DATABASE_URL configured to point to PostgreSQL. This creates repeatable environments across development, staging, and production pipelines. - Concrete commit establishing the deployment surface and environment wiring: 2bcef182cc1bdd29fad6bec203c5579ac68218e6 (feat: adding compose and .env configs). - Lays groundwork for subsequent service features and CI/CD improvements by adding reusable deployment configurations to the base repository. Major bugs fixed: None reported this month. Overall impact and accomplishments: Accelerates time-to-deploy for the Lessons Service, reduces environment drift, and improves reliability of local/dev/stage deployments. Demonstrates end-to-end deployment readiness and practical application of containerized services in a PostgreSQL-backed architecture. Technologies/skills demonstrated: Docker, Docker Compose, PostgreSQL integration, environment variable management, containerized service deployment, repo configuration and deployment wiring in Git-backed project base.
