Before getting started, ensure you have:

• Basic Linux or Windows command-line knowledge
• Git installed
• A GitHub account
• Visual Studio Code (recommended)

Clone this repository:

git clone https://github.com/sammad00/git_for_devops.git

Navigate into the project:

cd git_for_devops

Verify Git installation:

git --version

Initialize a repository:

git init

Check repository status:

git status

Add files:

git add .

Commit changes:

git commit -m "Initial commit"

View commit history:

git log --oneline

Create a new branch:

git branch feature

Switch to a branch:

git checkout feature

Or using the modern command:

git switch feature

Merge a branch:

git merge feature

Pull the latest changes:

git pull origin main

Push changes:

git push origin main

Clone a repository:

git clone <repository-url>

main
 │
 ├── dev
 │     │
 │     ├── feature/login
 │     ├── feature/docker
 │     └── feature/api
 │
 └── hotfix

Typical workflow:

1. Create a feature branch from dev.
2. Make and commit your changes.
3. Push the feature branch to GitHub.
4. Open a Pull Request.
5. Merge into dev.
6. Test changes.
7. Merge dev into main for production releases.

• Write clear and descriptive commit messages.
• Commit small, focused changes.
• Pull before pushing to avoid conflicts.
• Use feature branches for new work.
• Keep the main branch stable.
• Review Pull Requests before merging.
• Use .gitignore to exclude unnecessary files.
• Avoid committing secrets, passwords, or API keys.
• Tag stable releases using Git tags.

Git plays a central role in DevOps by enabling:

• Source Code Management (SCM)
• CI/CD Pipelines
• Infrastructure as Code (IaC)
• Team Collaboration
• Automated Deployments
• Version Tracking
• Release Management
• Change Auditing
