Step-by-Step Guide: How to Run GitLab Locally on Your Machine

by ·

Running GitLab on your local machine can be a great way to test, develop, and manage your projects without relying on external servers. This guide will walk you through the process of setting up GitLab locally, from preparing your environment to troubleshooting common issues. By the end of this tutorial, you’ll have a fully functional GitLab instance running on your computer.

Key Takeaways

  • Ensure your system meets the necessary requirements before starting the installation.
  • Follow the step-by-step instructions to install GitLab and GitLab Runner on your local machine.
  • Learn how to configure GitLab for local use, including setting up user accounts and projects.
  • Understand how to run and monitor CI/CD jobs using GitLab Runner locally.
  • Get tips on troubleshooting common issues that may arise during the setup process.

Setting Up Your Environment

Before diving into the installation of GitLab, it’s crucial to set up your environment properly. This ensures a smooth installation process and optimal performance of GitLab on your local machine.

Installing GitLab Locally

Downloading the GitLab Package

First, you need to get the GitLab package. Use a server with internet access to download it. If your setup is completely offline, you might need to use a USB drive to transfer the package. Make sure you have all the dependencies before proceeding.

Run the following command to prepare the repository:

curl --silent "https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.deb.sh" | sudo bash

Next, download the GitLab package and its dependencies:

sudo apt-get install --download-only gitlab-ee

Copy the downloaded files to your offline server using a USB drive or any other method.

Running the Installation Script

Once you have the package on your offline server, navigate to the directory where you copied the files. Install the dependencies first:

sudo dpkg -i <dependency_package>.deb

After installing the dependencies, install the GitLab package:

sudo dpkg -i gitlab-ee_<version>.deb

Make sure your DNS is set up correctly. Change https://gitlab.example.com to your desired URL. The installation will automatically configure and start GitLab at that URL.

Initial Configuration Steps

After the installation, you need to do some initial configuration. Open your browser and go to the URL where GitLab is installed. Log in with the username root and the password stored in /etc/gitlab/initial_root_password.

Set up your communication preferences to receive important updates and security alerts. You can opt-in for newsletters and other notifications.

Pro Tip: If you don’t opt-in to the security newsletter, you won’t receive critical security alerts.

Consider the recommended next steps, like setting up authentication options and sign-up restrictions. This will help you secure your GitLab instance and make it ready for use.

Configuring GitLab for Local Use

Setting Up User Accounts

First things first, you need to set up user accounts. This is where you add team members who will be working on your projects. Head over to the Admin Area and click on ‘Users’. Here, you can add new users by entering their email addresses and setting up their roles. Make sure to set strong passwords and consider enabling two-factor authentication for added security.

Configuring Projects and Repositories

Next, let’s configure your projects and repositories. Navigate to the ‘Projects’ section and click on ‘New Project’. Fill in the project name, description, and visibility level. You can choose to initialize the repository with a README file. Once the project is created, you can start adding files and setting up your repository structure. Use branches to manage different versions of your project and merge requests to review and integrate changes.

Adjusting Security Settings

Security is crucial when running GitLab locally. Go to the ‘Settings’ menu and select ‘Security’. Here, you can configure various security options like setting a minimum password length, enabling two-factor authentication, and restricting sign-ups to specific email domains. You can also set up IP restrictions to limit access to your GitLab instance. Don’t forget to regularly update your GitLab instance to the latest version to ensure you have the latest security patches.

Remember, a well-configured GitLab instance not only improves productivity but also ensures the security of your code and data.

Running GitLab Runner Locally

Installing GitLab Runner

First, you need to install GitLab Runner on your local machine. The installation process varies depending on your operating system. For example, on macOS, you can use the following command to download the binary:

sudo curl --output /usr/local/bin/gitlab-runner "https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-darwin-amd64"

After downloading, make the binary executable:

sudo chmod +x /usr/local/bin/gitlab-runner

Registering the Runner

Once installed, you need to register the runner with your GitLab instance. Open a terminal and run the following command:

sudo gitlab-runner register

Follow the prompts to complete the registration process. You will need to provide your GitLab instance URL, the registration token for your project, and any other required information. After registration, the runner should be available in the project’s Runners section in GitLab.

Running Jobs Locally

With the runner registered, you can now run jobs locally. Define a .gitlab-ci.yml file at the root of your repository. This file outlines the CI/CD jobs you want to run. Here’s a simple example:

stages:
  - build
  - test
  - deploy

build:
  stage: build
  script:
    - echo "Building the project..."
    - make build

test:
  stage: test
  script:
    - echo "Running tests..."
    - make test

deploy:
  stage: deploy
  script:
    - echo "Deploying the project..."
    - make deploy

This example defines three stages: build, test, and deploy. Each stage is a job composed of one or more script commands executed in order. Once your .gitlab-ci.yml file is configured, push it to your repository, and GitLab will automatically run the jobs using your local runner.

Running GitLab Runner locally is a great way to test your CI/CD pipelines without needing a dedicated server. However, keep in mind that using a local runner can have some limitations, such as lack of scalability and availability compared to using a runner on a dedicated machine or in a cloud environment.

Testing Your Setup

Creating a Test Project

First, let’s create a test project to ensure everything is working. Open GitLab and click on the New Project button. Choose a blank project and give it a name like ‘TestProject’. Once created, clone the repository to your local machine using the provided URL.

Writing a Simple CI/CD Pipeline

Next, we need to write a simple CI/CD pipeline. Create a file named .gitlab-ci.yml in the root of your project. Add the following content:

stages:
  - test

test_job:
  stage: test
  script:
    - echo "Running tests..."
    - echo "Tests passed!"

This pipeline has one stage called test and a job named test_job that simply prints messages.

Running and Monitoring Jobs

Commit and push the .gitlab-ci.yml file to your repository. Go to your GitLab project and navigate to CI/CD > Pipelines. You should see your pipeline running. Click on the pipeline to monitor the job’s progress. If everything is set up correctly, you should see the messages "Running tests…" and "Tests passed!" in the job logs.

Tip: If the pipeline fails, double-check your .gitlab-ci.yml file for any syntax errors or typos.

By following these steps, you can confirm that your GitLab setup is working correctly. Now you’re ready to start building more complex pipelines and automating your workflows.

Troubleshooting Common Issues

Installation Problems

Sometimes, GitLab installation doesn’t go as planned. Check your system requirements first. Make sure you have enough RAM and disk space. If the installation script fails, try running it with sudo. Also, verify your internet connection; a slow or unstable connection can cause issues.

Runner Registration Issues

Having trouble registering your GitLab Runner? Ensure the URL and token are correct. If you see a 403 error, double-check your permissions. Sometimes, restarting the Runner service can fix the problem. If all else fails, re-register the Runner.

Pipeline Failures

Pipelines can fail for many reasons. Check your YAML syntax first. A small typo can break the whole pipeline. Look at the job logs for specific error messages. If a job is stuck, try canceling and re-running it. Also, make sure your Docker images are up-to-date.

Quick Tip: Always keep your GitLab and Runner versions in sync to avoid compatibility issues.
