Worked on enhancing the DayMarket/infra-docker repository by improving Docker image support for Maven builds, focusing on reliability and reproducibility within CI/CD pipelines. The approach involved updating the Dockerfile to include essential tools such as curl and openssh-client, enabling more robust Maven build processes inside the container. Additionally, a standardized Maven settings.xml was incorporated to ensure consistent configuration across different CI environments, reducing environment drift and making builds more predictable. This work leveraged skills in Docker, build tools, and CI/CD, utilizing Dockerfile and XML to deliver a more stable and maintainable infrastructure for automated build workflows.
