How to install GitLab on Clear Linux Latest

In this tutorial, we will guide you on how to install GitLab on Clear Linux Latest. GitLab is an open-source DevOps platform that enables you to manage, secure, and deploy your code. By the end of this tutorial, you will have a functional GitLab instance running on your Clear Linux system.

Prerequisites

Clear Linux Latest installed on your system.
Administrative access to your Clear Linux system.

Step 1: Install Docker

GitLab can be run on a Clear Linux system using Docker. Therefore, we need to install Docker first.

Open your terminal and execute the following command to update the package database:
```
sudo swupd update
```
Install Docker using the following command:
```
sudo swupd bundle-add containers-basic
```
Verify the installation of Docker using the following command:
```
sudo systemctl status docker
```
A "running" status indicates that Docker is installed and running.

Step 2: Install GitLab

We can install GitLab on our Clear Linux system by running its Docker image. Follow these steps to install GitLab on Clear Linux.

Pull the GitLab Docker image using the following command:
```
sudo docker pull gitlab/gitlab-ce:latest
```
Create a new directory to store GitLab data:
```
sudo mkdir -p /opt/gitlab/data
```

Create the docker-compose.yml file with the following contents:

gitlab:
  image: gitlab/gitlab-ce:latest
  restart: always
  hostname: gitlab.example.com
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      external_url 'http://gitlab.example.com:30080'
  ports:
    - "30080:80"
    - "30022:22"
  volumes:
    - /opt/gitlab/data:/var/opt/gitlab

Replace the hostname and external_url with your own values.

Start the GitLab container using the following command:
```
sudo docker-compose up -d
```
Wait for the GitLab installation to complete. You can check the installation progress and logs using the following command:
```
sudo docker logs -f gitlab
```
The installation process may take several minutes to complete.
Once the installation is complete, you can access GitLab using your web browser by navigating to the URL http://<hostname>:30080. You should see the GitLab login page.

Note: Replace <hostname> with the value you used in the docker-compose.yml file.
