🚀 Kubernetes ConfigMaps & Secrets | Complete Hands-On Tutorial (Live DevOps Lab) In this live session, we dive deep into ConfigMaps and Secrets in Kubernetes — two essential resources used to manage application configuration and sensitive data in containerized environments. If you're learning Kubernetes, preparing for CKA / CKAD, or working in DevOps, understanding how to properly separate application configuration from container images is critical. In this session we build everything from scratch using kubectl and run real commands in a Kubernetes cluster. 📚 What you will learn in this live session: ✔ What ConfigMaps are and why they are important ✔ What Secrets are and how they differ from ConfigMaps ✔ Creating ConfigMaps using kubectl commands ✔ Creating ConfigMaps using YAML manifests ✔ Injecting ConfigMaps as environment variables ✔ Importing entire ConfigMaps using envFrom ✔ Mounting ConfigMaps as files inside containers ✔ Creating and using Kubernetes Secrets ✔ Base64 encoding in Secrets explained ✔ Real cluster demonstrations using the nehraclasses namespace ✔ Debugging ConfigMaps and Secrets using kubectl 💻 Hands-on Commands Covered kubectl create configmap kubectl describe configmap kubectl apply -f kubectl exec kubectl edit configmap kubectl get pods -n namespace kubectl describe pod 🎯 Who should watch this? • Kubernetes beginners • DevOps engineers • Cloud engineers • CKA / CKAD exam preparation • Anyone working with containerized applications 🧠 Why ConfigMaps & Secrets Matter Modern applications should never hardcode configuration or credentials inside container images. Kubernetes provides ConfigMaps and Secrets to safely inject configuration at runtime. By the end of this session, you will be able to design production-ready Kubernetes applications with proper configuration management. *** 📚 Nehra Classes - Igniting The Minds! 📚 About Us: Nehra Classes is a premier IT training institute dedicated to empowering individuals with the skills and knowledge they need to succeed in today's competitive technology landscape.
