As a developer, you often need to collaborate with a team on the same Git repository. This involves each team member working on separate branches and merging their changes to a main branch when complete.
However, sometimes you only want to push your local changes to a specific remote branch rather than the entire repo. Git allows you to do this through some simple commands.
In this comprehensive guide, we‘ll cover:
- What pushing changes to a remote branch means in Git
- When you‘d want to push to a specific branch
- Step-by-step instructions to push local changes to a remote branch
- Integrating branch-specific pushes into workflows
- Best practices for pushes and GitOps
- Common issues and solutions when pushing to remote branches
What Does "Pushing Changes to a Remote Branch" Mean?
In Git, "pushing" refers to uploading your local commits to a remote repository like GitHub. By default, git push uploads all of your local branch commits to the corresponding branch on the remote.
However, you can also choose to push commits from just a single local branch to its remote counterpart. For example, pushing only your local feature-x branch to the origin/feature-x branch on GitHub. This allows you to isolate changes instead of pushing your entire local repo state.
When Would You Want to Push to a Specific Branch?
Here are some common scenarios where pushing to a specific remote branch is useful:
-
Collaborating on a feature branch: Multiple developers can isolate their work to a shared feature branch without impacting main.
-
Preparing pull requests: You often create pull request branches to propose specific changes rather than directly pushing to main.
-
Reverting remote changes: If bad changes get pushed to a remote branch, you can revert just that branch without losing other work.
-
Branch-specific backups: You might push certain sensitive branches to remote backups for extra safety.
Additional Examples
-
Team experiments: Teams can test out experimental features or research spikes in an isolated branch.
-
Gradual rollouts: Pushing to a release candidate branch lets you incrementally roll out to subsets of users.
-
Dependency updates: Upgrading dependencies could cause breaking changes, so having a separate branch lets you test properly.
-
Long running tasks: Data science or machine learning tasks can run directly in isolated branches.
Pushing to specific branches gives you more control and flexibility when collaborating and integrating changes. It‘s an essential technique for Git-based team workflows.
Step-by-Step Guide to Push Local Changes to a Remote Branch
Follow these steps to push commits from your local Git repository to a single remote branch:
1. Navigate to Your Local Repository
First, open your terminal and navigate into the root directory of your local Git repository:
cd path/to/local/repo For example:
cd ~/Documents/website-project2. Check the Remote Repository URL
Before pushing to a remote branch, verify that your local repository is connected properly using:
git remote -vThis lists all remote connections for fetching and pushing, like:
origin https://github.com/user/website-project.git (fetch)
origin https://github.com/user/website-project.git (push)This origin remote points to the main repository you want to push your branch to.
3. Fetch the Latest Remote Branch State
Next, fetch the latest files from the remote branch to ensure you have its most up-to-date state before pushing:
git fetch origin This pulls down commits from all branch tracks without merging anything.
4. Checkout the Local Branch to Push
Now checkout the local branch containing the commits you want to push.
For example, to push your new-feature branch:
git checkout new-featureThe branch must already exist locally and have commits before you can push.
5. Push the Local Branch Commits to Remote
Finally, push your local branch commits using:
git push origin your-branch-nameFor example:
git push origin new-feature This pushes the new-feature local branch to the origin/new-feature branch on the remote repository.
Git will output details about what commits got pushed. And now your local branch changes will appear in the remote repository!
Integrating Branch Pushes Into Your Git Workflows
Beyond basic push/pull workflows, leveraging targeted branch pushing unlocks additional Git workflow possibilities:
Feature Branch Workflow
Teams can collaborate while keeping unstable changes isolated from the main codebase. By only pushing localized feature branches, you prevent new bugs from blocking others.
GitOps Pipelines
Many teams adopt a GitOps approach where application state and infrastructure are declaratively defined as code. Special Git branches act as the single source of truth that tools listen to for deployments.
Release Validation
Push your latest changes to a staging branch monitored by automated tests rather than straight to production. This lets you validate before releasing to customers.
Decentralized Experiments
Developers can leverage branches to individually test out ideas without coordination. The best experiments can later be integrated back upstream.
Gradual Rollouts
Release management teams often use feature flags and canary deployments to incrementally rollout changes. Updating specific branches aids this by providing incremental batching.
By incorporating branch-based pushes into larger workflows, teams can scale collaboration while reducing integration issues.
Best Practices for Pushing Branches
Follow these best practices when pushing local topic branches to remote counterparts:
-
Communicate branch purpose – Use descriptive branch naming schemes that indicate the context and purpose of that branch.
-
Limit WIP branches – Avoid pushing too many stale branches that leave work-in-progress (WIP) changes lingering without being finished.
-
Test before pushing – Make sure you run tests locally before pushing to remotes to not disrupt other developers.
-
Force push with care – The
--forceflag overrides the remote branch with no merging. Use cautiously to not lose collaborator changes. -
Delete old branches – Remember to delete merged branches from the remote so they don‘t pile up over time.
-
Protect release branches – Use protected branches to prevent directly pushing to critical branches like production.
Following Git push best practices helps reduce integration headaches from changes spanning multiple branches.
Common Issues Pushing to Remote Branches
Here are some common errors you may encounter when trying to push local branches to remote counterparts:
Push Rejected Due to Remote Changes
If the remote branch contains commits that your local branch doesn‘t, the push will fail with:
! [rejected] new-feature -> new-feature (non-fast-forward) First fetch the remote changes and rebase your local branch to integrate them before pushing again.
No Existing Remote Branch Track
By default, git push only updates remote branches that your local ones track. If no remote branch exists yet, you‘ll see:
fatal: The current branch new-feature has no upstream branch.To create the remote branch, add the -u flag on your first push:
git push -u origin new-featureAccess Denied to Repository
Without proper access to push to the remote repo, your push will fail with:
remote: Permission to user/website-project.git denied to your-username. Make sure you are working from an account with write access to the repository.
How Branch Pushes Integrate With Continuous Delivery Pipelines
Many teams utilize continuous delivery (CD) pipelines that automatically build, test, and deploy application changes whenever code gets pushed to key branches.
Some ways branch-specific pushes interact with CD pipelines include:
- Push to trigger pipeline – Pushing feature branches can kick off isolated pipelines for testing.
- Static analysis on push – Code quality toolsinjected into the pipeline analyze the branch code.
- Deploy previews from branches – Branches deploy to specific environments for testing like QA sandboxes.
- Route traffic to branches – Use a router service to redirect a portion of traffic to a specific branch.
- Progressive deliveries – Roll out changes in gradual batches by slowly shifting traffic mix between branches.
Properly integrating pipelines with branch-based development improves velocity, safety, and reliability. Teams operating in regulated industries like healthcare, finance, etc. greatly benefit from the additional controls.
According to Statista, 68% of organizations now implement continuous delivery with Git and branches playing a central role:
Alternative Git Push Options
The typical git push command provides a baseline of uploading your branch changes to the remote. However, Git offers additional options that come in handy in specific cases:
–force Flag
The --force flag forces the push to overwrite remote changes even if branches diverged:
git push --force origin my-branch Be very careful with this as you can lose collaborator changes.
–no-verify Flag
The remote repository can have configured hooks that run on each push via the pre-receive and update triggers. The --no-verify flag skips these verification scripts.
git push --no-verify origin my-branchThis lets you bypass checks meant to protect the remote state.
Pushing Tags
In addition to pushing commits from local branches, you can also upload local Git tags using:
git push origin v1.2.3Tags let you version milestone releases across branches.
Conclusion
Pushing commits from a local branch to a related branch on a remote repository is extremely useful for collaborating with teams and preparing your changes to go live.
The process requires just:
- Navigating your local Git repo
- Verifying the remote URL
- Fetching the latest remote state
- Checking out your local branch
- Pushing with
git push origin your-branch
Following this Git push tutorial, you should now understand how to isolate your local changes by only pushing specific branches rather than your entire repository state.
This gives you more control over what changes make it onto a remote and makes branch-focused workflows much easier. Leverage targeted pushing to improve team collaboration and simplify coordinating ongoing development!
