GitLab-Runner is the indispensable execution agent within the GitLab CI/CD pipeline. As a core scheduling component, it retrieves and precisely executes automated jobs defined in `.gitlab-ci.yml` from the GitLab CI/CD coordinator. Renowned for its exceptional flexibility and scalability, GitLab-Runner supports task execution across diverse environments, including virtual machines, Docker containers, and Kubernetes clusters, offering multiple executor options such as shell, Docker, and SSH. It efficiently processes multiple jobs in parallel, ensuring automated code builds, testing, and deployment. This significantly accelerates development cycles and markedly enhances software delivery efficiency and quality, making it a critical foundation for modern, high-performance DevOps pipelines.
