Hands-On Auto DevOps with GitLab CI - Creating GitLab CI Configuration

This video tutorial introduces the GitLab CI YAML file, explaining its role in customizing build configurations. It starts with a basic example, demonstrating how to create a simple job that always succeeds. The tutorial covers how GitLab CI creates pipelines and the default stages involved. It explains the importance of exit codes in determining build success and how to handle failures. The video also discusses using Docker images to control the build environment, ensuring consistency across builds. The tutorial concludes with a preview of the next video, which will cover building and testing with Docker.
