GitLab Runners are components used for automating jobs, such as building, testing, and deploying projects. It is important to understand the distinction between different types of runners when setting up your project.
A specific runner is assigned to a single project. It will run jobs only for this project. It can be used for jobs that require specific hardware or software, or for jobs that need to be run on a specific environment.
A shared runner is a runner that is available to all projects on the GitLab server. It can be used for jobs that don’t require specific hardware or software.
A group runner is a specific runner that is assigned to a group of projects. It will run jobs for all the projects in the group. This is useful when you want jobs to be run on a specific environment for all the projects in the group.
When setting up your project, it is important to understand the distinction between different types of runners. Depending on your project’s needs, you can decide to use a specific runner, a shared runner, or a group runner.
