Day 55: Kubernetes Sidecar Containers | 100 Days of DevOps – KodeKloud Engineer

Welcome to Day 55 of the 100 Days of DevOps – KodeKloud Engineer Series! 🚀

In today’s Kubernetes lab, we implement one of the most important patterns in modern cloud-native architecture — the Sidecar Container Pattern.
This hands-on task teaches you how to use a sidecar container to ship logs from an Nginx web server without modifying the application container itself.

📌 Scenario:
Nautilus developers need access to the last 24 hours of Nginx logs for debugging, but log data doesn’t need to be stored on persistent volumes. So, we deploy:

nginx-container → serves the web pages
sidecar-container (Ubuntu) → continuously reads access/error logs
Both containers share an emptyDir volume mounted at /var/log/nginx

This shows how Kubernetes sidecars help with observability, log collection, and separation of concerns—all without touching the main application code.

🔥 In this video, you’ll learn:

✔ What is the Sidecar Container Pattern
✔ Why sidecars are used in logging, security, proxies, and service mesh
✔ How to share volumes using emptyDir
✔ How to create multi-container Pods in Kubernetes
✔ How to continuously stream logs from one container to another
✔ How to mount shared volumes at the same path
✔ How Nginx writes logs and how the sidecar reads them

This is a real DevOps skill used in production clusters worldwide (EKS, GKE, AKS, OpenShift).
If you're preparing for DevOps interviews, CKA/CKAD, or looking to become a Kubernetes engineer — this episode is GOLD.🏆
