Fast and natural continuous integration with GitLab CI

What this post added

This post introduces the core concepts of GitLab CI/CD, including its YAML configuration file, the role of runners in executing build scripts, secrets management for authorization tokens, the concept of pipelines as a sequence of steps from source code to deployment, the container registry for storing Docker images, and environments/review apps for dynamic per-branch deployments. It highlights the advantages of a tightly coupled CI/VCS system, versioned CI configuration, out-of-the-box Docker integration, an artifacts browser, and reduced maintenance overhead for CI servers. It also discusses potential drawbacks such as a 'convention over configuration' model and fewer plugin integrations compared to other CI tools.
