Git workflow: Remote

👀 Overview

In this module, you will learn how to work with a remote repository using GitHub and GitLab (look at the tutorial).

You will clone a remote repository, update your local repository and push changes to the remote.

Additionally, you will learn how to create a Merge Request to propose changes to the original repository.

🎯 Goals

  • Clone an existing repository from the remote.
  • Update the local repository with changes made on the remote repo.
  • Push changes from the local repository to the remote.
  • Create a Merge Request to propose changes to the original repository.

⚒️ Tutorial: Work with the remote repository (GitLab)

1. Create and clone a repository

To clone a repository means to download the files from the remote repository to your computer and to create a connection between them.

To clone a repository:

  1. Open a terminal and go to the directory where you want to clone the files

  2. Copy the Git SSH URL of the repository (REPO_URL)

    Copy the Git URL

  3. Clone the repository using the command git clone in the CLI.

git clone REPO_URL

Note

Git automatically creates a folder with the repository name and downloads the files there.

2. Create and Update dev branch, push it to the remote

Now let’s see how to work with a remote repository using GitHub.

  1. First, we navigate to our 3-git-remote directory using the command cd 3-git-remote.

# Go to the repository 
cd 3-git-remote
2. Then, we need to create a new branch called dev. In this way, you can make changes without affecting the main codebase. And we immediately switch to a new branch with the command git checkout -b dev.

# Create `dev` branch and checkout to it (-b flag)
git checkout -b dev
3. Next, we create a new file called config.yaml using the touch command and add a line to it using echo "repo: project-1-git" >> config.yaml. We confirm the changes using cat config.yaml. This command will print the file’s content.

# Create a config file, make changes, confirm them
touch config.yaml 
echo "repo: project-1-git" >> config.yaml
cat config.yaml
4. Also, we add and commit the changes to the local repository using

# Add and commit changes
git add config.yaml && git commit -m "Add config.yaml"
5. Finally, we push our changes to the remote repository (named origin) in the ‘dev’ branch using the git push origin dev command. 

# Push changes to the remote repository
git push origin dev

3. Create a Merge Request: dev → main

Create a Merge Request via GitHub or GitLab UI to the main branch

🏁 Conclusion

Congratulations on completing this tutorial! 🥳

You have learned how to work with a remote repository. You set up SSH to connect to GitHub / GitLab, cloned a remote repository, updated your local repository, and pushed changes to the remote.

Furthermore, you learned how to create a Merge Request to propose changes to the original repository.
