Designing Multi-Container Pods in Kubernetes Using Init and Sidecar Containers

Description

This project demonstrates how to design and deploy multi-container pods in Kubernetes using Init and Sidecar containers. It covers shared volume communication, container lifecycle sequencing, and container collaboration within a single pod. The goal is to replicate real-world DevOps use cases and reinforce practical skills needed for CKA/CKAD certification and production-grade Kubernetes environments.

Tools & Technologies

• Kubernetes (Minikube)
• Init & Sidecar Containers
• Nginx, BusyBox
• YAML, kubectl
• Shared Volumes (emptyDir)

Project Walk-through

1. Define Multi-Container Pod in YAML


2. Deploy the Pod


3. Verify Init Container


4. Simulate Web Traffic


5. Check Sidecar Logs
