You can add multiple push urls to a single origin by using git remote origin set-url --add --push <url> . This is helpful if you have a repository hosted on Github and you would like to mirror it to Gitlab on every push.
By default git has a single remote url that is used for both push and pull. In the config you can configure multiple pushurl instead of relying on the url .
Demo
This repository is currently configured just for Github
$ git remote -vv
origin git@github.com:zqureshi/daily (fetch)
origin git@github.com:zqureshi/daily (push)
I can set a pushurl to the same repo
$ git remote set-url --add --push origin git@github.com:zqureshi/daily
$ git remote -vv
origin git@github.com:zqureshi/daily (fetch)
origin git@github.com:zqureshi/daily (push)
Now I can add the Gitlab repo as another pushurl
$ git remote set-url --add --push origin git@gitlab.com:zqureshi/daily.git
$ git remote -vv
origin git@github.com:zqureshi/daily (fetch)
origin git@github.com:zqureshi/daily (push)
origin git@gitlab.com:zqureshi/daily.git (push)
Note: The first step of setting the existing url as a pushurl is necessary because when you set a pushurl it overrides the current url. If I were to simply execute the second Gitlab command then I would be pushing to Gitlab and pulling from Github, which is not what we want.
A git push should now show multiple uploads
