Method To Install and configure GitLab runner on centos 7

Introduction:

GitLab Runner is an application that works with GitLab CI/CD to run jobs in a pipeline. GitLab Runner is open-source and written in Go. It can be run as a single binary; no language-specific requirements are needed. GitLab Runner can also run inside a Docker container or be deployed into a Kubernetes cluster.

Installation Procedure:

Step 1 : Check the installed OS version by using the following command

linuxhelp@linuxhelp:~$ cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"

Step 2: Login to your Gitlab account and go inside any project Snap1

Step 3: Navigate the project to find the settings and move to the CI/Cd section

Step 4: Follow the instruction given under the specific runners sections

Step 5 : To install GitLab Runner, Add the official GitLab repository

Step 7 : Now its time to register the runner To register a runner under Linux: Run the following command:

root@linuxhelp:~# sudo gitlab-runner register
Enter the GitLab instance URL (for example, https://gitlab.com/):
http://192.168.6.115/
Enter the registration token:
azCS4D5nSBbLE9zjJ-R3
Enter a description for the runner:
[linuxhelp]: Ci
Enter tags for the runner (comma-separated):
cui pipeline
Registering runner... succeeded                     runner=azCS4D5n
Enter an executor: kubernetes, custom, docker, shell, docker+machine, docker-ssh+machine, docker-ssh, parallels, ssh, virtualbox:
shell
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!.

With this installation and configuration of Gitlab runner on centos 7 comes to end.
