SSH for Gitlab in Ubuntu Steps

If you are a programmer, chances are that you use Git for version control. Git is a powerful tool that allows you to manage your codebase and collaborate with other developers. In addition, Gitlab is a popular web-based Git repository manager that provides features such as code reviews, issue tracking, and continuous integration.

To use Gitlab effectively, you should configure SSH on your Ubuntu machine. SSH (Secure Shell) is a secure protocol that lets you access remote systems securely. In this tutorial, we will walk you through the steps to set up SSH for Gitlab on Ubuntu.

Prerequisites

Before you begin, ensure the following:

• You have a Gitlab account with an SSH key.
• You have access to an Ubuntu machine.
• You have sudo privileges on the Ubuntu machine.

Step 1: Install OpenSSH Client

First, install the OpenSSH client on your Ubuntu machine:

sudo apt-get install openssh-client

This will install the OpenSSH client, which is necessary to connect to remote systems over SSH.

Step 2: Generate SSH Key

Next, you need to generate an SSH key on your Ubuntu machine. This key will be used to authenticate with Gitlab. To generate an SSH key, run the following command:

ssh-keygen

This will prompt you to enter a passphrase, which is an additional layer of security. You can leave this blank for now.

Step 3: Add SSH Key to Gitlab

Now, you need to add your SSH key to Gitlab. To do this, copy the contents of the public key file (~/.ssh/id_rsa.pub) to your clipboard:

cat ~/.ssh/id_rsa.pub | xclip -selection clipboard

Next, log in to your Gitlab account and navigate to your profile settings. Click on "SSH Keys" and paste your key into the "Key" field. Give it a name and click "Add Key" to save it.

Step 4: Test SSH Connection

Finally, you can test your SSH connection to Gitlab. To do this, run the following command:

ssh -T git@gitlab.com

This will attempt to connect to Gitlab over SSH and display a welcome message if successful.

Congratulations! You have now configured SSH for Gitlab on Ubuntu. This will allow you to securely manage your codebase and collaborate with other developers.
