Git Tagging

Add Tag.

git tag -a v1.0 -m 'version 1.0'

git tag -a v1.0 -m 'version 1.0' c4283bb

Push Tag to remote origin (All TAG)

git push --tag

Push Tag to remote with specific tag.

git push origin tag v1.0

Here is how to delete a tag from a remote Git repository.

If you have a tag named '12345' then you would just do this:

    git tag -d 12345  git push origin :refs/tags/12345  

That will remove '12345' from the remote repository.
