How to Install GitLab CI on macOS

GitLab CI is a continuous integration and continuous deployment tool that is integrated with GitLab. In this tutorial, we will guide you on how to install GitLab CI on macOS.

Prerequisites

Before we proceed with the installation, you need to have the following requirements:

• A macOS system that is capable of running Docker.
• Docker Desktop for macOS.
• Basic knowledge of using the terminal.

Installation steps

1. Open your terminal and run the following command to create a new folder:

mkdir gitlab-ci

2. Change the current directory to the newly created folder by running:

cd gitlab-ci

3. Next, we will need to create a new file named docker-compose.yml and add the following content:

version: '3'
services:
  gitlab-runner:
    image: gitlab/gitlab-runner:latest
    container_name: gitlab-runner
    volumes:
      - ./config:/etc/gitlab-runner
      - /var/run/docker.sock:/var/run/docker.sock
    restart: always

4. Next, let's start the containers by running the following command:

docker-compose up -d

This command will start the GitLab Runner container and mount the config folder to the /etc/gitlab-runner directory in the container.

5. Now, let's register a new runner. Run the following command:

docker-compose exec gitlab-runner gitlab-runner register

6. Follow the prompts to configure the runner. You'll need to enter your GitLab instance URL and runner token.

7. Once you've successfully registered your runner, you can start using it in GitLab CI.

Congratulations! You have now successfully installed GitLab CI on macOS.

Conclusion
