During October 2025, Bert Wesarg developed a feature for the gitlabhq/gitlab-runner repository that enables dynamic Docker service configuration within CI/CD pipelines. By expanding variables in the image.docker.* options, he allowed Docker services to be set up based on job-specific variables, reducing manual configuration and increasing pipeline flexibility. This approach leveraged Go for implementation and incorporated Docker and Kubernetes skills to enhance the reliability of Docker-based runners in GitLab deployments. The work, co-authored with Axel von Bertoldi, demonstrated a focused engineering effort to address dynamic service creation, resulting in a more adaptable and maintainable CI/CD workflow.
