Let’s talk about the process and precautions for deploying GitLab

With the rapid development of today's engineering management, version control systems are becoming more and more important. Git is a very popular distributed version control tool. GitLab is Git's web management interface. It is a complete DevOps platform that can make team collaboration more convenient and code management more convenient. In this article, we will introduce the process and precautions for deploying GitLab.

1. Install and configure the required software

Before starting to install GitLab, we need to install and configure Docker and Docker-compose. Both software need to be configured accordingly according to different operating systems. After the installation is complete, we need to set the environment variables of Docker and Docker-compose in the system to facilitate subsequent use.

2. Create a GitLab container

After installing the required software and configuring environment variables, we can start creating a GitLab container. Deployment of GitLab containers using Docker-compose is very simple. You only need to create a docker-compose.yml file in the current directory and fill in the following content:

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'
    gitlab_rails['gitlab_shell_ssh_port'] = 22
ports:
  - '80:80'
  - '443:443'
  - '22:22'
volumes:
  - '/srv/gitlab/config:/etc/gitlab'
  - '/srv/gitlab/logs:/var/log/gitlab'
  - '/srv/gitlab/data:/var/opt/gitlab'
network_mode: host

In this docker-compose.yml file, we specify the required Docker image, host name, port, mounting directory and other parameters of the container. Can be customized as needed.

3. Start the GitLab container

Starting the GitLab container is very simple, just run the following command in the current directory:

docker-compose up -d

This command will automatically start the GitLab container and run it in the background.

4. Log in and use GitLab

Once the GitLab container is started successfully, we can access http://gitlab.example.com through the browser. On the first visit, the system will ask us to set up the administrator account and password, as well as some other system configurations. Once setup is complete, you can start using GitLab.

Summary:

In this article, we describe how to use Docker-compose to deploy GitLab and provide a simple docker-compose.yml template. Pay attention to configuring the required software and environment variables, confirm that the container creation parameters are correct, then run the GitLab container and log in to use it. By managing the development work of the team with GitLab, collaboration efficiency will be greatly improved.
