Following on from their previous project which detailed how to install GitLab on the Raspberry Pi 4, Hackster.io member Mikrocontroller Projekte has published a new project providing more details about the usage of GitLab CE on a Raspberry Pi 4 mini PC running 4GB of RAM.
The second part of the tutorial explores more about the usage of GitLab CE on a Raspberry Pi mini PC including generating a SSH key pair for authentication, creating and pushing a project to your GitLab server, cloning a project from your GitLab server and more. “Create Push and Clone your STM32 microcontroller projects with Git on your own private GitLab server running on a Raspberry Pi 4 with 4GB!”
Setting Up GitLab CE on Raspberry Pi 4
The project requires you have a Raspberry Pi 4 model B preloaded with the Raspberry Pi Raspbian operating system. The initial setup involves installing GitLab CE, which is the Community Edition of GitLab, a web-based DevOps lifecycle tool that provides a Git repository manager providing wiki, issue-tracking, and CI/CD pipeline features, using an open-source license. This setup transforms your Raspberry Pi into a powerful tool for managing your code repositories.
To begin, ensure your Raspberry Pi is updated and has the necessary dependencies installed. This includes packages like curl, openssh-server, and ca-certificates. Once these are in place, you can proceed to download and install GitLab CE using the official GitLab repository.
Generating SSH Key Pair for Authentication
One of the critical steps in using GitLab CE is generating an SSH key pair for secure authentication. SSH keys are a more secure and convenient way of logging into a server with SSH than using a password alone. To generate an SSH key pair, you can use the `ssh-keygen` command on your Raspberry Pi. This will create a public and private key pair that you can use to authenticate with your GitLab server.
Once you have your SSH keys, you need to add the public key to your GitLab account. This allows GitLab to recognize your device and grant it access to your repositories. You can do this by navigating to the SSH Keys section in your GitLab profile settings and pasting your public key there.
Creating and Pushing a Project to GitLab
With your SSH keys set up, you can now create a new project on your GitLab server. This can be done through the GitLab web interface by clicking on the “New Project” button. You can choose to create a blank project, import a project from another repository, or use a template.
After creating your project, you can push your code to the GitLab server. This involves initializing a Git repository in your project directory, adding your files, committing the changes, and then pushing them to the remote GitLab repository. The commands for these steps are as follows:
“`bash
git init
git add .
git commit -m “Initial commit”
git remote add origin git@your-gitlab-server:username/projectname.git
git push -u origin master
“`
Cloning a Project from GitLab
Cloning a project from your GitLab server to your local machine is equally straightforward. This is useful when you want to work on your project from a different device or share it with collaborators. To clone a project, you can use the `git clone` command followed by the SSH URL of your repository. For example:
“`bash
git clone git@your-gitlab-server:username/projectname.git
“`
This will create a local copy of your repository on your machine, allowing you to make changes and push them back to the GitLab server.
