[Gitlab] HOW TO USE SPECIFIC RUNNERS IN GITLAB CI/CD PIPELINE

What are Gitlab Runners?

GitLab Runner is an application that works with GitLab CI/CD to run jobs in a pipeline. They can also run

inside a Docker container or be deployed into a Kubernetes cluster.

Types of Runners:

• Shared Runner: These types of runners are available globally and can automatically be allocated based on their availability.
• Specific Runner: For this, you have to register a runner and you can only use it in a specific project or can also use it in a specific stage of your pipeline. Will discuss this more in detail.
• Group Runner: These runners are shared across projects in the group.

How to register a specific runner?

sudo gitlab-runner register

This command will start the process of registering a runner. Then go to the Gitlab Project -Settings->CI/CD->Runners and copy the URL of specific runners.
