Let’s talk about the construction and use of gitlab

With the rapid development of software development, our code collaboration and version management during the development process are becoming more and more important. Git is one of the most mainstream and popular version control systems today. GitLab is a very powerful source code management tool based on Git. It has many unique features, such as rich functions and ease of use. This article will introduce you to the construction and use of GitLab.

1. Overview of GitLab

GitLab is an open source code hosting and collaboration platform that can help us better manage code and implement a true DevOps platform. It can run on-premises or in the cloud and provides powerful source code management, CI/CD automation, code review, and vulnerability detection. By using GitLab, teams can easily share and collaborate on code, improving the productivity and code quality of the entire team.

2. How to build GitLab

1. Preparation

Before you start installing GitLab, you need to ensure that Docker and Docker Compose are installed on the operating system. Docker is an open source platform that helps us build, publish and run applications. Docker Compose is a Docker configuration tool that can help us easily define and run multiple Docker containers.

2. Get the GitLab installation package

You can get the latest version of the GitLab installation package from the Docker Store. Please make sure to select the version appropriate for your operating system.

3. Download the installation package

Use Docker Compose to create a Docker container containing GitLab. Run the following command:

mkdir -p /srv/gitlab/config /srv/gitlab/data /srv/gitlab/logs
cd /srv/gitlab/
touch docker-compose.yml

Add the following content in the file docker-compose.yml:

version: '3'
services:
  web:
    image: 'gitlab/gitlab-ce:latest'
    restart: always
    hostname: 'gitlab.example.com'
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'http://gitlab.example.com'
        nginx['listen_port'] = 80
        nginx['listen_https'] = false
        gitlab_rails['gitlab_shell_ssh_port'] = 2224
    ports:
      - '80:80'
      - '443:443'
      - '2224:22'
    volumes:
      - '/srv/gitlab/config:/etc/gitlab'
      - '/srv/gitlab/logs:/var/log/gitlab'
      - '/srv/gitlab/data:/var/opt/gitlab'

Here, you need to change hostname Name it the GitLab hostname you want to use. Also, set external_url as the URL for GitLab (in this example, "http://gitlab.example.com").

4. Start the container

Use the following command to start the container:

docker-compose up -d

5. Access GitLab

GitLab is already Successfully deployed on your server. You can access http://gitlab.example.com through a browser and log in using the default administrator username "root" and password "5iveL!fe".

3. How to use GitLab

In GitLab, you can create a project, add members, manage repositories, and more. The following will briefly introduce some of the main functions of GitLab.

1. Create Project

Click the "New Project" button and you will be taken to the project creation page. On the project creation page, you can enter information such as the project's name, description, and access level. Select the "Create Project" button and GitLab will create a project for you.

2. Add members

Select "Members" in the left menu of the project page. You can add, edit, and remove project members. For each member, you can set their roles and permissions.

3. Manage Repository

At the top of the project page you will see a repository URL. You can use this URL to clone the project to your local computer. You can use the web interface provided by GitLab to manage the contents of your repository, or you can use the Git CLI (command line interface) to make local adjustments. GitLab supports various version control operations, such as submitting code, merge requests, etc.

4. CI/CD Automation

GitLab also provides powerful CI/CD automation capabilities. Select the CI/CD menu above the project page and you can configure a pipeline to set up automated workflows. By setting up these workflows, you can automate building, testing, and deploying applications.

5. Code Review and Vulnerability Detection

With built-in code review tools, you can easily review code submitted by your team members. In addition, GitLab also provides vulnerability detection and security analysis tools that can help you easily detect and resolve potential security issues.

4. Summary

Through this article, you should have a deeper understanding of the construction and use of GitLab. You can use Docker to quickly deploy GitLab and start using it within your team for code collaboration and management. Not only that, you can configure automated CI/CD pipelines in GitLab and use its built-in review tools and vulnerability detection tools to improve the quality and security of your code.
