How to use git to log in to gitlab and pull branch code

In team collaboration development, version control is an indispensable part. Git is a very popular version control tool that allows team members to collaborate on code development and facilitate code management and maintenance. Gitlab is a Git-based code hosting platform that supports teams for collaborative development in projects.

The code repository in Gitlab consists of the main branch (master) and multiple development branches (branch). During the project development process, it is usually necessary to pull the code of a certain development branch for development and testing. This article will introduce how to use Git to log in to Gitlab and pull the code of the development branch.

Step one: Register a Gitlab account and create a code repository

First you need to register a Gitlab account and create a code repository. After registering on Gitlab's official website, click the "New project" button in the upper right corner and follow the prompts to create a new code repository. After the warehouse is created, you can start to manage the code.

Step 2: Install the Git client

Git is a command line tool and you need to install the Git client locally. In Windows systems, you can download the installation package from the Git official website for installation. In Linux systems, the Git client can be installed through the command line.

Step 3: Generate SSH key

In order to improve security, Gitlab uses the SSH protocol for code interaction and needs to generate an SSH key. Enter the following command in the Git client:

$ ssh-keygen -t rsa -C "your_email@example.com"

where "your_email@example.com" needs to be replaced with your own email address.

Next, just follow the prompts and press Enter. The generated SSH key will be saved in the .ssh folder in the user's home directory.

Step 4: Add the SSH key to the Gitlab account

Add the generated SSH key to the Gitlab account for authentication when interacting with the code. Enter the following command in the Git client:

$ cat ~/.ssh/id_rsa.pub

will output a public key generated by the SSH key. Copy this public key to "Settings"-"SSH Keys" of your Gitlab account and add it.

Step 5: Log in to Gitlab through the Git client

Enter the following command in the Git client:

$ git config --global user.name "your_username"
$ git config --global user.email "your_email@example.com"

where "your_username" needs to be replaced with the username of the Gitlab account. "your_email@example.com" needs to be replaced with your own email address.

Then log in to Gitlab through the following command:

$ git clone git@gitlab.com:your_username/your_project.git

where "your_username" needs to be replaced with the Gitlab account The username, "your_project" needs to be replaced with the name of the code repository created on Gitlab.

Step 6: Pull the development branch code

After cloning the code repository locally, you can pull the code of a development branch through the following command:

$ git checkout -b your_branch origin/your_branch

where "your_branch" needs to be replaced with the corresponding development branch name. If you want to pull the master branch code, you can use the following command:

$ git checkout -b master origin/master

The above are the steps to log in to Gitlab using Git and pull the branch code. In the actual development process, using Git and Gitlab can facilitate team collaboration development and version control management.
