Creating a branch from a tag in Git
This article introduces how we can create a new branch based on a tag in Git. If you are a regular Git user, you must know the purpose of Git tags.
These tags are just pointers to meaningful Git commits. The question is: how do you create a branch based on a Git tag?
Creating a branch from a tag in Git
If we run git log
the command, we can see the commits with tags. Here is our commit history:
Suppose we want to create a new branch based on tag v1.o.5 at the Release v1.0.5 - Bump Codebase Version commit. How would we go about this?
This is pretty simple. We'll use the git branch command as follows:
$ git checkout -b Tag-Branch v1.0.5
This command will create a new branch called Tag-Branch and bring all commits to tag, including the commit at tag. Let's check if this is the case.
We can see that Git has created a new branch. Creating the branch deletes the commit after our tag.
Alternatively, we can choose to reset HEAD to the tag and create a new branch based on head. This is not a clean approach as you will remove commits from your branch.
You can run the following command:
$ git reset --hard <tag>
$ git checkout -b newbranch
In summary , Git allows us to create new local branches based on any tag in the repository. Using git reset --hard
the option is not always the best choice.
git branch -b new-branch <tag>
A cleaner way to create branches based on tags.
