In October 2025, João Meier developed Docker Compose support for the Classes microservice within the pucrs-constrsw-2025-2/base repository. He defined a new service in docker-compose.yml, specifying build context, image, environment variables, network, ports, and a health check to ensure reliable deployment and monitoring. By integrating the Classes API into the existing multi-service setup, João streamlined deployment automation and improved environment consistency across development and production. His work leveraged Docker, Docker Compose, and YAML to enable seamless building, running, and observability of the microservice, addressing operational reliability and accelerating integration timelines for the broader microservices architecture.
