61_1: Introduction to Git in DevOps

This lab focuses on the foundational Git operations required in DevOps workflows. We will convert a local folder into a Git repository, track changes, and optionally connect it to a remote repository hosted on Oracle Cloud Infrastructure or GitHub.

61_2: Initial Setup - Check Git Version

Before starting, ensure Git is installed on your system.

git --version

61_3: Initialize a Git Repository

Navigate to the desired folder and run the following command:

git init

This converts your current folder into a Git repository. You will now see a hidden .git folder created.

61_4: Check Repository Status

git status

This shows untracked files and the current state of your working directory.

61_5: Add Files to Git

Add all files:

git add .

Add a specific file:

git add filename

61_6: Commit Changes

git commit -m "Initial commit with Terraform script"

This records the snapshot of your project in version history.

61_7: Configure Git Identity

Set up your global username and email (only needed once):

git config --global user.name "Your Name"

git config --global user.email "[email protected]"

61_8: Make a Change to a File

Example:

vi Bastion_server_1.tf

Make edits and save the file.

61_9: Commit the Changes Again

git add Bastion_server_1.tf

git commit -m "Updated Bastion server configuration"

61_10: View Commit Log

git log --graph --oneline --all

This provides a visual history of your commits.

61_11: Creating a Remote Repo (Optional)

If you're using Oracle Cloud or GitHub, create a remote repo and connect your local repo to it:

git remote add origin <remote-repo-url>

git push -u origin master

61_12: Conclusion

You now understand how to:

• Initialize and manage a Git repository locally

• Track and commit changes

• View commit history

• Optionally connect to a remote repo for versioning and collaboration
