What Is Yaml File in Git

From version 7.12, GitLab CI uses a YAML file ( . gitlab-ci. yml ) for the project configuration. It is placed in the root of your repository and contains definitions of how your project should be built. The YAML file defines a set of jobs with constraints stating when they should be run.

WHAT IS services in GitLab CI Yml?

The services keyword defines a Docker image that runs during a job linked to the Docker image that the image keyword defines. This allows you to access the service image during build time. The service image can run any application, but the most common use case is to run a database container, for example: MySQL.

How does GitLab CI yml work?

gitlab-ci. yml file to your repository, GitLab detects it and an application called GitLab Runner runs the scripts defined in the jobs. In this example, the build-code-job job in the build stage runs first. It outputs the Ruby version the job is using, then runs rake to build project files.
