How to use Docker to automatically build GitLab? (Tutorial)

GitLab is a powerful open source version control system that can meet the code management, version control, collaborative development and other needs of software teams. In practical applications, GitLab can provide developers with a collaborative platform, making multi-person collaborative development more efficient.

This article will introduce how to use Docker to automatically build GitLab.

Step one: Install Docker

Download Docker suitable for your operating system from the Docker official website and install it.

Step 2: Pull the GitLab image

Enter the following command in the terminal:

docker pull gitlab/gitlab-ce:latest

Wait for the image pull to complete before proceeding to the next step.

Step 3: Create a GitLab container

Enter the following command to start the container:

docker run --detach \
    --hostname www.gitlab.com \
    --publish 443:443 --publish 80:80 --publish 22:22 \
    --name gitlab \
    --restart always \
    --volume /srv/gitlab/config:/etc/gitlab \
    --volume /srv/gitlab/logs:/var/log/gitlab \
    --volume /srv/gitlab/data:/var/opt/gitlab \
    gitlab/gitlab-ce:latest

The meaning of each parameter in the above command is as follows:

-- hostname: Specify the domain name of GitLab.

--publish: Map the container port to the host port.

--name: Specify the name of the container.

--restart: Set the restart policy of the container.

--volume: Specify the mounted data volume.

gitlab/gitlab-ce:latest: Specify the image name and version number.

In the above command, you need to pay attention to the following points:

1. Do not repeat the container naming with other containers.

2. Use necessary port mapping.

3. The mounted data volume must be created on the host first.

Step 4: Access GitLab

After the container is started, you can enter the IP address or customized domain name in the browser to access GitLab.

When accessing for the first time, you need to set the administrator account and password.

At this point, we have completed the automatic construction of GitLab and can carry out code management, version control and team collaboration.

Summary:

It is very simple to automatically build GitLab using Docker, and it can be easily completed with only a few commands. Using GitLab can improve the efficiency of collaboration between development teams and better ensure code version control and management. It is one of the indispensable tools in the software development process.
