Automated DevOps Productivity and Reliability Measurement using GitHub Actions

This project automates the collection, visualization, and security validation of DevOps productivity metrics (DORA) using GitHub Actions and Python.

🚀 Features

• Automated CI/CD pipeline (Build → Test → Security Scan → Deploy)
• Automatic logging of deployments to metrics.csv
• DORA metrics calculation via Python
• Graph visualization of Deployment Frequency
• Real-time project badges (status indicators)

⚙️ Pipeline Overview

1. Build – Simulated build step
2. Test – Verifies basic functionality
3. Security Scan – Checks for vulnerabilities before deployment
4. Deploy – Copies and logs deployment
5. Metrics Update – Appends data to metrics.csv

📊 Python Analysis Scripts

• calculate_metrics.py → Calculates DORA metrics
• visualize_metrics.py → Generates charts for deployment frequency

🧰 Setup in VS Code (Windows)

1. Clone your GitHub repo.
2. Extract these files into the repo folder.
3. Open in VS Code → run the following once:

   git init
   git add .
   git commit -m "init: project scaffold"
   git branch -M main
   git remote add origin https://github.com/<your-username>/devops-metrics-demo.git
   git push -u origin main

4. Enable GitHub Actions → check the Actions tab.

🧪 Generate Data

To simulate multiple runs:

echo "<p>Version update</p>" >> index.html
git add index.html
git commit -m "feat: update version"
git push

To simulate a failed deploy:

git commit -m "test: simulate [fail]" --allow-empty
git push

📈 Visualize Results

Run:

python calculate_metrics.py
python visualize_metrics.py

Then include deployment_frequency_chart.png in your report.

🛡️ Security Integration

Each run now includes a Security Scan (Simulated) stage to validate code before deployment — aligning the project with DevSecOps principles.
