Git – 20 Use Cases with Explanations

20 Use Cases with Explanations

      ◉  Version control for application codebases
           Git helps developers track changes, manage versions, and collaborate efficiently by maintaining a history of modifications.

      ◉  Collaborating with multiple developers using feature branches
           Teams can work on separate branches, isolate features, and merge them into the main branch after review.

      ◉  Implementing GitOps workflows for infrastructure
           Git repositories act as the source of truth for Kubernetes manifests, enabling automated infrastructure deployment.

      ◉  Reverting code to a previous stable commit after failure
           Developers can use git revert or git reset to undo changes and restore previous working states.

      ◉  Managing documentation in versioned markdown files
           Documentation can be updated alongside code, maintaining synchronization between features and their descriptions.

      ◉  Tracking and auditing changes in configuration files
           Git logs show who changed what and when, providing audit trails for compliance and debugging.

      ◉  Code review workflows via pull requests
           Developers submit pull requests for team review before merging, improving code quality and shared knowledge.

      ◉  Hotfix deployments via cherry-picking commits
           Critical bug fixes can be cherry-picked from development branches into production for quick deployment.

      ◉  Integrating Git hooks for automated code linting
           Pre-commit hooks can run linters or tests before changes are committed, ensuring consistency.

      ◉  Tagging production releases
           Tags help identify stable versions of the codebase that correspond to deployments or releases.

      ◉  Performing codebase rollbacks in Kubernetes deployments
           Git history enables rollback to a previous version of Kubernetes manifests or Helm charts.

      ◉  Integrating with Jenkins pipelines for CI triggers
           Pushes or PRs in Git can trigger automated Jenkins CI/CD pipelines using webhooks.

      ◉  Maintaining monorepos with subtree splitting
           Git supports subtree operations to manage components or services in a single repository.

      ◉  Managing Terraform module versions
           Infrastructure modules stored in Git can be versioned and reused with specific commits or tags.

      ◉  Investigating blame history for root cause analysis
    git blame shows which line was last changed by whom, helping trace bugs.

      ◉  Syncing forks with upstream branches
           Forked repositories can pull in updates from upstream sources to stay up to date.

      ◉  Creating release notes from commit messages
           Structured commit messages can be parsed to generate changelogs for releases.

      ◉  Enforcing branch naming conventions with pre-push hooks
           Git hooks enforce naming policies like feature/ or hotfix/ for better repo hygiene.

      ◉  Automating semantic versioning
           Scripts can analyze Git history to increment major, minor, or patch versions.

      ◉  Maintaining commit hygiene using rebase and squash
           Developers clean up commit history before merging using rebase -i to squash or reorder commits.
