Final Project: Scalable Web App with Docker & Kubernetes

[GOKUL-P-R]

🎯 Final Project Submission - evn-dop-shipyard26-ship

Objective Completed ✅

Package a simple web application using Docker, deploy it to a Kubernetes cluster, and verify scaling using multiple replicas.

✅ Docker Phase

• Created index.html (Professional portfolio-style web app)
• Created Dockerfile using nginx:alpine
• Built Docker image successfully: scalable-web-app:latest

✅ Kubernetes Phase

• Created KIND cluster: shipyard (v1.27.3)
• Loaded Docker image to KIND cluster
• Created deployment.yaml with 3 replicas
• Added STUDENT_NAME environment variable (GOKUL P R)
• Deployed and verified all pods running (3/3)

✅ Self-Healing Test - PASSED

• Deleted pod: scalable-web-app-7858587768-4d827
• New pod auto-created: scalable-web-app-7858587768-2qd7t
• Recovery time: 3 seconds
• Replica count maintained: 3/3
