GitLab CI/CD is a continuous integration and delivery tool that is built into GitLab. It provides a fast and automated way to build, test, and deploy your code changes.
Continuous Integration (CI) is the process of automatically building and testing code changes every time someone commits code to a repository. This helps catch issues early on in the development process and ensures that the code base is always in a working state.
Continuous Delivery (CD) is the process of automatically deploying code changes to production after they have been tested and approved. This helps speed up the release process and ensures that new features and bug fixes are delivered to users quickly and reliably.
GitLab CI/CD allows you to define jobs and pipelines in a YAML configuration file. Jobs define the individual steps of the build, test, and deployment process, while pipelines define the order and dependencies between those jobs. GitLab CI/CD also supports parallel and distributed builds, allowing for faster build times.
Overall, GitLab CI/CD is a powerful tool for automating your software development process and improving the quality and reliability of your code releases.
