GitLab-Runner

About

GitLab-Runner is an indispensable execution agent in the GitLab Continuous Integration/Continuous Delivery (CI/CD) pipeline. As a core scheduling component, it is responsible for pulling and executing automated jobs defined by `.gitlab-ci.yml` from the GitLab CI/CD orchestrator. GitLab-Runner offers high flexibility and scalability, supporting task execution across various environments including virtual machines, Docker containers, and Kubernetes clusters, and providing multiple executors (e.g., shell, docker, ssh). It can process multiple jobs in parallel, thereby ensuring automated building, testing, and deployment of code, accelerating development cycles, and significantly improving software delivery efficiency and quality. It is a critical enabler for building modern DevOps pipelines.
