Demo Setup Github repo according to DevOps best practice 02

Welcome back! In this lesson, we'll walk through enabling branch protection on GitHub and establish a workflow using feature branches and pull requests.

Enabling Branch Protection

1. In your repository, navigate to Settings > Branches.
2. Click Add branch protection rule.
3. Set Branch name pattern to main.
4. Enable Require a pull request before merging.
5. Uncheck Require approvals if you're working solo.
6. Scroll down and click Create.

Once created, your protected rule appears in the list:

Working with Feature Branches

First, verify your current branch in VS Code:

git branch
* main

Creating a Feature Branch

Switch to a new branch for your task:

git checkout -b feature/task-02
git branch
* feature/task-02
  main

Updating the README

1. Open README.md.
2. Change the heading from #### to # for an H1 title.
3. Preview your changes to confirm the update.

Staging and Committing

Stage and commit the revision:

git add README.md
git status
# On branch feature/task-02
# Changes to be committed:
git commit -m "Update README.md to use H1 heading"

Pushing the Feature Branch

Push your branch to GitHub:

git push origin feature/task-02

You should see a message prompting you to create a pull request:

remote: Create a pull request for 'feature/task-02' on GitHub by visiting:
remote:   https://github.com/learnwithraghu/gcp-devops-project/pull/new/feature/task-02

Creating and Merging a Pull Request

1. Click Compare & pull request in the GitHub banner.
2. On the Open a pull request page:
   • Title: Update README.md to use H1 heading
   • Description: Update the README file to make the first line a heading
3. Review your changes and click Create pull request.

4. Click Merge pull request, then Confirm merge (approvals are not required for solo projects).

After merging, your main branch includes the change. This clear, repeatable process scales with team size and project complexity.
