 Day 01 : 💡 Technical Tip of the Day: Kubernetes Made Simple Ever struggled to explain  Pods ,  ReplicaSets , and  Deployments  in Kubernetes? Here's a lightbulb analogy that makes it crystal clear: 🔹  Pod = Single Lightbulb The basic unit of work - one container (or a few tightly coupled ones) running together. 🔹  ReplicaSet = Light Switch Ensures a specific number of bulbs are always on. If one burns out, it automatically replaces it to maintain your desired count. 🔹  Deployment = Smart Home System The intelligent orchestrator that: ✅ Controls the number of bulbs (like ReplicaSet) ✅ Seamlessly upgrades to new, energy-efficient models (rolling updates) ✅ Rolls back to old bulbs if the new ones flicker (rollback capability) Why this matters:  Understanding these core concepts is essential for anyone working with containerized applications. Each layer adds more intelligence and automation to your infrastructure. What's your favorite analo...

 Here is the Day 01 Video on DevOps / SRE Engineer training Day 01 - Homework Create a directory named day1_practice. Inside day1_practice, create two more directories: configs and logs. Use touch to create an empty file named app.conf inside the configs directory. Use ls -lR (the R is for recursive, to see everything inside) on your day1_practice directory to see the structure you've built. Now, practice cleaning up by removing the app.conf file and then the configs and logs directories.
