Why Git integrates with CI/CD - See It in Action

Why Git Integrates with CI/CD

📖 Scenario: You work in a team that builds software. You use Git to save your code changes. Your team wants to make sure the code is always tested and ready to use. This is done using CI/CD tools that run tests and deploy code automatically.

🎯 Goal: Learn how Git connects with CI/CD by creating a simple Git repository, adding a configuration file to trigger CI/CD, and seeing the result of the integration.

📋 What You'll Learn

Create a Git repository with a README file

Add a CI/CD configuration file named .github/workflows/ci.yml

Write a simple CI job that runs on push

Show the Git commands to push changes and trigger CI/CD

💡 Why This Matters

🌍 Real World

Teams use Git with CI/CD to automatically test and deploy code changes, saving time and reducing errors.

💼 Career

Understanding Git and CI/CD integration is essential for software developers, DevOps engineers, and anyone working in modern software teams.

1

Create a Git repository with a README file

Initialize a Git repository in the current folder using git init. Then create a file named README.md with the exact content # My Project. Finally, add the file to Git using git add README.md.

Git

# Initialize Git repository and add README.md
# Your code here

Need a hint?

Use git init to start a new repository. Use echo to create the README file. Use git add to stage the file.

2

Add a CI/CD configuration file

Create a folder named .github/workflows. Inside it, create a file named ci.yml with the following content exactly:

name: CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: echo "Running tests..."

Git

git init

echo "# My Project" > README.md

git add README.md
# Create .github/workflows/ci.yml with CI job
# Your code here

Need a hint?

Create the folders with mkdir -p. Use echo with escaped quotes to write the YAML file.

3

Commit and push changes to trigger CI/CD

Commit your changes with the message "Add CI workflow" using git commit -m "Add CI workflow". Then push to the remote repository using git push origin main. Assume the remote is already set.

Git

git init

echo "# My Project" > README.md

git add README.md

mkdir -p .github/workflows

echo "name: CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: echo \"Running tests...\"" > .github/workflows/ci.yml
# Commit and push changes
# Your code here

Need a hint?

Use git commit -m to save changes with a message. Use git push origin main to send changes to the remote.

4

Show the output of the CI job running

Print the exact text Running tests... to simulate the CI job output.

Git

git init

echo "# My Project" > README.md

git add README.md

mkdir -p .github/workflows

echo "name: CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: echo \"Running tests...\"" > .github/workflows/ci.yml

git add .github/workflows/ci.yml

git commit -m "Add CI workflow"

git push origin main

# Print the CI job output
# Your code here

Need a hint?

Use echo "Running tests..." to show the CI job output.
