Version Control
This outline provides information on version control using Git for the getting-started project on GitHub.
Git Basics
Git is a distributed version control system used to track changes in files over time. It enables collaboration among developers and maintains a history of changes for easy rollback or revision.
- Repository: A central location where all project files and their version history are stored.
- Commit: A snapshot of the repository at a specific point in time.
- Branch: A separate line of development, allowing developers to work on features without affecting the main codebase.
- Merge: Combining changes from one branch into another.
Using Git with the Getting Started Project
This project uses Git to manage its source code, enabling developers to contribute and track changes effectively.
Cloning the Repository:
git clone https://github.com/docker/getting-started.git
Creating a New Branch:
git checkout -b feature/new-feature
This creates a new branch named feature/new-feature and switches to it.
Making Changes:
# Make your changes to the codebase
Committing Changes:
git add .
git commit -m "Add new feature"
This adds all changes to the staging area and commits them with a descriptive message.
Pushing Changes:
git push origin feature/new-feature
This pushes the changes to the remote repository on GitHub.
Merging Changes:
Once your changes are ready, you can merge them into the main branch:
git checkout main
git merge feature/new-feature
Resolving Merge Conflicts:
If there are conflicts during the merge, Git will highlight the conflicting lines. You must manually resolve these conflicts before committing the merge.
Pull Request:
After pushing your changes, you can create a Pull Request on GitHub. This allows other developers to review your code and provide feedback before merging it into the main branch.
Other Useful Git Commands:
git status: Shows the current state of the repository.git diff: Displays the changes made since the last commit.git log: Shows the commit history.git revert <commit_hash>: Reverts a specific commit.git reset --hard <commit_hash>: Resets the current branch to a specific commit.
Collaboration with Others
Git facilitates collaboration by allowing developers to work on different features concurrently and integrate their changes seamlessly.
Pull Requests:
Developers create pull requests on GitHub to propose changes and receive feedback from others.
Reviewing Pull Requests:
Reviewers can comment on code changes, suggest improvements, and approve or reject pull requests.
Merging Pull Requests:
Once a pull request is approved, the changes can be merged into the main branch.
Branching Model:
The getting-started project utilizes a branching model to structure development workflows. Typically, feature branches are created for new features or bug fixes. Once the changes are ready, these branches are merged into the main branch.
