CI/CD Pipeline

Every push to the main branch automatically:

• Checks out the repository
• Authenticates with AWS
• Builds Docker images
• Pushes images to Amazon ECR
• Connects to Amazon EKS
• Updates Kubernetes Deployments
• Waits for rollout completion

---

AWS Services Used

• Amazon EC2
• Amazon EKS
• Amazon ECR
• IAM
• VPC
• Application Load Balancer (ALB)

---

Running Locally
