GIT106 - Remote Repositories Explained

Remote repositories allow you to store your project on external servers and collaborate with others.
Platforms like GitHub, GitLab, and Bitbucket make it easy to back up your projects and share work with teams.

What Is a Remote Repository?

A remote repository is a version of your project hosted on a server.
It enables collaboration, backups, automation, and more.

Common remote platforms:

• GitHub
• GitLab
• Bitbucket

Remote repositories do not replace your local repo.
Instead, your local and remote repositories synchronize via Git commands like push, pull, and fetch.

Adding a Remote Repository

After creating a new repository on a platform like GitHub, link it to your local project:

git remote add origin https://github.com/username/myproject.git

Verify the remote:

git remote -v

Expected output:

origin  https://github.com/username/myproject.git (fetch)
origin  https://github.com/username/myproject.git (push)

Pushing Changes to a Remote Repository

Your first push must specify the upstream branch:

git push -u origin main

Future pushes require only:

git push

This uploads your local commits to the remote server.

Pulling Changes From Remote

To download and merge changes from the remote to your local repository:

git pull

This performs two actions:

1. Fetch remote changes
2. Merge them into your current branch

Fetching Without Merging

Fetch downloads remote changes without modifying your working files:

git fetch

Use this when you want to inspect updates before merging.

Compare fetched updates with your branch:

git diff main origin/main

Changing or Removing a Remote

Update the remote URL:

git remote set-url origin https://gitlab.com/newrepo.git

Remove a remote entirely:

git remote remove origin

Cloning a Remote Repository

Clone copies the entire project history and sets up the origin remote automatically:

git clone https://github.com/username/project.git

This creates:

• A new folder
• A complete history copy
• A configured remote named "origin"

Working With Multiple Remotes

You may add additional remotes for collaboration:

git remote add upstream https://github.com/original-author/project.git

Fetch updates from this remote:

git fetch upstream

Merge changes into your local branch:

git merge upstream/main

Checking Remote Information

List all remotes:

git remote

Show detailed info:

git remote show origin
