📚 Welcome to Day 26! 🚀
Today, we begin our journey into Kubernetes storage by focusing on ephemeral storage—data that lives and dies with the pod. Understanding this is essential before we explore persistent volumes in the next session.

📝 What We’ll Cover:
✅ What is Ephemeral Storage in Kubernetes?
✅ emptyDir Volumes – Sharing data between containers in a Pod
✅ downwardAPI – Exposing pod metadata like name, namespace, labels, and resource limits to containers
✅ Use Cases for Ephemeral Volumes
✅ Best Practices and Caveats for Temporary Storage
✅ Real-world Demos to reinforce each concept

💡 By the end of this lecture:
You'll understand how Kubernetes handles temporary storage needs, how containers share data in a pod, and how you can expose useful pod-level information to your applications—setting the stage for persistent storage in Day 27!
