During April 2025, this developer enhanced the PrairieLearn/PrairieLearn repository by implementing Docker Compose inter-container networking to streamline workspace container communication. The solution involved adding a host.docker.internal mapping (172.17.0.1) to the extra_hosts section in the Docker Compose configuration, aligning development and production environments for more reliable integration and testing. By leveraging DevOps practices and working extensively with Docker and YAML, the developer reduced orchestration friction and improved deployment workflows. No major bugs were addressed during this period, with the primary focus on delivering a single feature that improved network configuration consistency across different stages of the development lifecycle.
