A new GIT branch can be created from a tag through the “git checkout” command with the “-b” option followed by a new branch name and tag name.

$ git checkout -b <new-branch> <tag-name>

Why Create Git Branch from a Tag

GIT tags are created to mark a specific point in git history and then deployed. But sometimes you might want to debug the deployed code and the best way is to create a new GIT branch from that tag.

How to Create Git Branch from a Tag

Let’s say you have deployed tag v2.0 on production and now you have some issues after the deployment.

Now creating a debug branch from the tag v2.0 will be the best way to make sure you have the exact code which is deployed on production.

Now let's go through each step one by one to create a new branch from the correct tag.

1. Get the tag

Make sure you fetch all the tags from your remote repository with the "git fetch" command

$ git fetch --all --tags

2. Confirm the tag

Now confirm that you have fetched the required tag v2.0 from which you want to create the branch.

$ git tag -l
v2.0
v1.0

3. Create a new branch from the tag

After confirming that tag v2.0 fetch properly, we can now run the "git checkout" command to create the new branch from that tag.

$ git checkout -b debug-tag-2-0 v2.0

Now we have a new branch "debug-tag-2-0" ready for debugging on local.

Conclusion

In this tutorial, we learned why we might need to create a new git branch from a tag for debugging and how this can be achieved with the "git checkout" command.

How to Create a Git Branch (WITH EXAMPLE)

Whenever you start developing a new feature you must start with creating a new branch git. This way you separate your feature changes from other branches.

A new branch can be created with the ‘git checkout’ command with the ‘-b’ option and a new branch name as arguments. This will create a new branch from your current branch and also switch the branch to the new branch.

$ git checkout -b <new-branch>

But if you don't want to create a new branch from the current branch then you can also pass the base branch as an argument.

$ git checkout -b <new-branch> <base-branch>

Once the feature is completed, this new branch can be merged back into the other branch.

Example of creating a GIT branch

Let's take an example, you want to create a new feature branch 'feature-2' from the master branch.

1. Checkout master branch (source branch)

First, make sure your current git branch is the master branch. You can check this by running "git branch" or "git branch --show-current" commands

$ git branch
feature-1
* master

If not, then make sure to checkout the master branch.

$ git checkout master

2. Run the "git checkout" command with "-b" and feature the branch name

Now you can run the GIT checkout command to create a new feature branch "feature-2"

$ git checkout -b feature-2
Switched to a new branch 'feature-2'

Once run successfully, the new branch will be created and your current branch will be switched to this new branch.

3. Confirm the new branch

You can verify your new branch by running the ‘git branch’ command.

$ git branch
feature-1
* feature-2
master

Conclusion

In this tutorial, we learned to create a new branch in GIT with the "git checkout" command. This can also be achieved with the "git branch" command.

A GIT branch is not the only source for creating a new feature branch. A New GIT branch can also be created from commit SHA, a tag, or a remote branch.
