Instructions

This section describes how to install and configure GitLab runner using docker on Fedora server some server.

1. Deploy virtual server in Portal

   (skip this section

   Info
   Skip this step if you already have a server

   )See article for instructions

   .  If you need new server, you can deploy one via TDS portal - Orchestration - Servers#Howtodeploynewserver

   
   

2. Install Docker engine on server ()Step by step (official instructions) – choose one of the following options

   • Option A - using "convenience script" from official instructions – recommended only for development and testing purposes

    Set up the repository

   • Code Block
     language bash

   $:

   • curl -fsSL https://get.docker.com -o get-docker.sh sudo sh get-docker.sh sudo systemctl start docker

     
     

   • Option B - specific approach for each relevant OS - basically setting up repository and installing Docker Engine - all supported OS instructions can be found at https://docs.docker.com/engine/install

     • CentOS - official instructions

       Code Block
       sudo yum install -y yum-utils sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

       
       

     • Fedora - official instructions

       Code Block
       sudo dnf -y install dnf-plugins-core

   $:

   • • sudo dnf config-manager

   • • --add-repo https://download.docker.com/linux/fedora/docker-ce.repo

   Install Docker Engine

   Code Block

   language	bash

   $:

   • • sudo dnf install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

   Convenience script (official instructions) - recommended only for testing and development purposes

   • • -y

       
       

     • Ubuntu - official instructions

       Code Block
       sudo apt-get update sudo apt-get install ca-certificates curl gnupg lsb-release -y sudo mkdir -m 0755 -p /etc/apt/keyrings

   Code Block

   language	bash

   • • curl -fsSL https://

   get

   • • download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o

   get-docker.sh sudo sh get-docker.sh

   • • /etc/apt/keyrings/docker.gpg echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

       
       

3. Add your user to docker group to be able to run docker commands (more about security in article)

   Code Block
   language bash
   sudo usermod -aG docker $USER

   
   

4. Start docker container with latest version of gitlab runner (official instructions)

   Code Block
   language bash
   $: docker run -d --name gitlab-runner --restart always \ -v /srv/gitlab-runner/config:/etc/gitlab-runner \ -v /var/run/docker.sock:/var/run/docker.sock \ gitlab/gitlab-runner:latest

   
   

5. Configure GitLab runner to connect to your repository
   1. In your Go to desired GitLab repository , go to → Settings → CI/CD → Runners
   2. You will need URL and registration token from Go to "Set up a specific runner for a project" section
      • Copy the "URL" and "registration token", you will need it in next steps

   3. Execute following command Call following on the server with running docker container

      Code Block

   4. You will be prompted to fill-in following parameters:
      • URL from step
      4
      • 5.
