How to install and register a gitlab runner on Ubuntu OS


Test Environment

Ubuntu 20.04 (
Ubuntu 20.04 (

Here in this article we will how we can install and register a gitlab runner with the gitlab server. We are going to use two Ubuntu servers. In one of the server we already have the gitlab server installation and setup done. We will be using the other server as gitlab runner and register it with the gitlab server.


Step1: Add Gitlab runner repository

As a first step in order to install the gitlab runner we first need to setup the repository from where we can download the gitlab runner package. We can setup the gitlab runner repository as shown below.

gitadmin@gitrunner:~$ curl -L "" | sudo bash
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  6885  100  6885    0     0  20863      0 --:--:-- --:--:-- --:--:-- 20863
Detected operating system as Ubuntu/focal.
Checking for curl...

Checking for gpg...

Running apt-get update... done.
Installing apt-transport-https... done.
Installing /etc/apt/sources.list.d/runner_gitlab-runner.list...done.
Importing packagecloud gpg key... done.
Running apt-get update... done.

The repository is setup! You can now install packages.

Step2: Install Gitlab runner

Once the repository setup is completed we can install the gitlab-runner package as shown below.

gitadmin@gitrunner:~$ sudo apt-get install gitlab-runner

Step3: Get a Gitlab runner registration token

In order to register a server as gitlab runner with the gitlab server, we first need to get the registration token from the gitlab server which we can obtain by going into the Admin setting of the gitlab server and under the Overview – gitlab runner section you can get the registration token as shown in below image.

Token – szsVcAg_hVeGGFegWeyR

Step4: Register Gitlab runner

Registering a runner is the process that binds the runner with one or more GitLab instances. You can register multiple runners on the same host machine, each with a different configuration, by repeating the register command.

Once we have the token we can run the below gitlab-runner register command in interactive mode by providing the required details about the gitlab server and the registration token and other details as asked below.

gitadmin@gitrunner:~$ sudo gitlab-runner register
Runtime platform                                    arch=amd64 os=linux pid=4994 revision=febb2a09 version=15.0.0
Running in system-mode.                            
Enter the GitLab instance URL (for example,
Enter the registration token:
Enter a description for the runner:
Enter tags for the runner (comma-separated):
Enter optional maintenance note for the runner:

Registering runner... succeeded                     runner=szsVcAg_
Enter an executor: parallels, ssh, docker+machine, docker-ssh+machine, custom, docker-ssh, virtualbox, kubernetes, docker, shell:
Enter the default Docker image (for example, ruby:2.7):
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

Now, you can verify in the gitlab server runner section that the runner is registered as shown below.
