Git: how to tag old commit

Another noob git tip. Tagging with git is easy and I won’t duplicate another explanation here. But suppose you want to tag a commit which you already pushed to another repo. When you push, nothing happens. I had tagged before, so I thought the problem was that I wanted to tag a commit which I already pushed.

But the trick to know here is: push simply does not push tags by default. You have to specify an option. So any tag you would want to share, on your last commit or any other commit, you would have to push explicitly:

git push origin <mytag>

or if you’d want to sync all tags in one go:

git push --tags origin

So, the title of this blog post was actually a trick question 😉
