🚀 DevOps Journey – Week 10 (Mastering Jenkins CI/CD)

#jenkins #devops #clouddeployment

🔹 Recap

This week was all about Jenkins. I built multiple pipelines and deployed my Node.js app to AWS EC2 using Jenkins. Now, when I update my GitHub repo and click Build Now, Jenkins automatically updates my app on EC2.

✅ Achievements

Set up Jenkins on my server

Configured Jenkins pipeline for Node.js app

Connected GitHub → Jenkins → EC2 deployment

Used PM2 to manage and restart the Node.js app

Automated CI/CD successfully 🎉
