Git Push To Multiple Repositories

Git is probably the best tool for version control and successful development team collaboration.

Usually, developers keep the codebase in one place, like GitHub or GitLab, but in some cases it may be necessary to work with the project stored in different locations and keep both in sync.

Today, after setting up two repositories, we will try to push the changes to both of them at the same time with just one command.

Push To Multiple Repositories

I have just created two empty repositories:

• GitLab - https://gitlab.com/vhudyma/original
• GitHub - https://github.com/volodymyrhudyma/copy

Let's say we are developing a project and the client wants it on GitLab, but for some reason we want the exact same copy on GitHub.

From the root folder of your project, add both repositories to the remotes:

git remote add original git@gitlab.com:vhudyma/original.git
git remote add copy git@github.com:volodymyrhudyma/copy.git

The git remote command is one piece of the broader system which is responsible for syncing changes. Records registered through the git remote command are used in conjunction with the git fetch, git push, and git pull commands.

Run the git remote -v command to ensure that both remotes were successfully added:

git remote -v

...

copy    git@github.com:volodymyrhudyma/copy.git (fetch)
copy    git@github.com:volodymyrhudyma/copy.git (push)
original    git@gitlab.com:vhudyma/original.git (fetch)
original    git@gitlab.com:vhudyma/original.git (push)

When listing remotes, we specified the -v flag, which displays the URLs that Git has stored for the short name when reading and writing to this remote.

Now you are able to perform a push to the selected remote by specifying it in the git push command:

git push original master
git push copy master

Now we know how to push changes to each repository separately, but how to push to both at once?

Step 1: Create a new remote named "all", and add GitLab and GitHub URLs to it

git remote add all git@gitlab.com:vhudyma/original.git
git remote set-url all --add --push git@gitlab.com:vhudyma/original.git
git remote set-url all --add --push git@github.com:volodymyrhudyma/copy.git

...

all     git@gitlab.com:vhudyma/original.git (fetch)
all     git@gitlab.com:vhudyma/original.git (push)
all     git@github.com:volodymyrhudyma/copy.git (push)
copy    git@github.com:volodymyrhudyma/copy.git (fetch)
copy    git@github.com:volodymyrhudyma/copy.git (push)
original    git@gitlab.com:vhudyma/original.git (fetch)
original    git@gitlab.com:vhudyma/original.git (push)

Step 2: Push the changes to the "all" remote

git push all master

And the change appears in both repositories.

Summary

In this article, we found out how to easily push code changes to multiple repositories.

This is very helpful if your team needs to maintain multiple copies of the project in different locations.

In summary, all you need to do is the following:

• Add a new remote "all" with multiple push URLs
• Push the changes there
