Hello Abdallah, Welcome to you at DevOps Industry.

The goal of this project is to practice DevOps end-to-end using:

• Java + Maven (Application)
• Docker (Containerization)
• GitHub (Source Control)
• Jenkins (CI/CD Automation)
• DockerHub (Image Registry)
• KIND Kubernetes Cluster (Deployment)
• UAT + Production Environments

📊 CI/CD Pipeline Flow

1. Developer pushes code to GitHub
2. Jenkins is triggered → builds + tests + creates Docker image
3. Docker image pushed to DockerHub
4. Jenkins deploys to KIND Cluster
   • First to UAT
   • Then to Production after approval
