[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.

How to use this specific runner in a pipeline?

Just add the tags field in your pipeline and name the tag which you added during the registration of a runner.

Here is the sample pipeline for your reference.

stage: test

script:

- echo "Testing"

- test -f "build/info.txt"

tags:

- testing

npm:

image: node:latest

stage: npm

[Gitlab] gitlab runner doesn`t work on a specific project

Ref: gitlab runner doesn`t work on a specific project

Error:

Fetching changes with git depth set to 50...
fatal: remote origin already exists.
fatal: git fetch-pack: expected shallow list
ERROR: Job failed: exit status 1

Solution:

Centos 7 ships with git version 1.8.3.1 . This version doesn't support commands like git fetch-pack . To fix this problem, you could update git on your server from the IUS repository. update git on Centos 7 to version 2 from third-party IUS repo

$ git --version
git version 1.8.3.1

sudo yum -y install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm
sudo yum install git
