How to determine whether Git and GitLab are connected successfully

When using Git and GitLab, it is very important to connect successfully. Only when the connection is successful can you perform code uploading and downloading, collaborative development, etc. The following will introduce how to determine whether Git and GitLab are successfully connected.

1. GitLab SSH Key configuration

GitLab SSH Key is an important credential for connecting to GitLab. If the SSH Key is not configured correctly, you cannot connect to GitLab.

The steps are as follows:

1. Use the command line terminal and enter the following command: ssh-keygen -t rsa -C "your_email@example.com" to generate the SSH Key.
2. Open the GitLab website, find SSH Keys in the user settings interface.
3. Copy the SSH Key just generated to GitLab's SSH Keys.
4. Open the terminal and enter the command: ssh -T git@your-gitlab-domain.com to test whether you can connect to GitLab successfully.

If the connection is successful, Welcome to GitLab, @username! will be output.

2. Clone the GitLab project

Before connecting to GitLab, you first need to clone the project that requires collaborative development to the local computer.

The steps are as follows:

1. In the GitLab project, find the SSH or HTTP warehouse link.
2. Open the terminal and use the command cd to enter the working directory of the local computer.
3. Use the command git clone plus the GitLab warehouse link to clone the project locally.
4. Enter the command ls in the terminal to list the files and folders in the working directory.

If the project file on GitLab appears, the clone is successful.

3. After commit and push

clone of the GitLab project, you can modify and upload the code. This requires the use of commit and push commands. Before using these two commands, you must ensure that Git and GitLab are properly connected.

The steps are as follows:

1. Enter the command cd in the terminal to enter the project directory.
2. Use the command git add to add the modified code to the staging area.
3. Use the command git commit -m "commit message" to submit the modified code.
4. Use the command git push to push the modified code to the GitLab server.

If the submission and push are successful, you will see a prompt message similar to "remote: Resolving deltas: 100% (1/1), done."

4. GitLab project pull

During team development, you may encounter other developers who have modified the project code and pushed it to GitLab. At this time, you need to use the pull command to pull the code to the local.

The steps are as follows:

1. Enter the command cd in the terminal to enter the project directory.
2. Use the command git pull to pull the code on GitLab.

If the pull is successful, you will see a prompt message similar to "Already up-to-date."

Through the above four steps, you can determine whether Git and GitLab are successfully connected.
