We’ll discuss why namespaces are important, how they isolate workloads, avoid naming conflicts, and help enforce security and resource limits. We’ll also demonstrate working with namespaces using imperative and declarative methods and show how to set a default namespace using Kubernetes context. 🌟 What You’ll Learn: ✅ What Are Kubernetes Namespaces and Why Do We Need Them? ✅ Default Namespaces and Their Purpose in a Cluster. ✅ Working with Namespaces: Creating, Listing, and Deleting. ✅ Cross-Namespace Communication: How Services and Pods Interact Across Namespaces. ✅ Setting a Default Namespace to Avoid Repetitive Namespace Flags. 💡 By the End of This Lecture: You'll have a strong understanding of namespaces, how to organize workloads effectively, and how to use namespaces for better security, isolation, and resource management in Kubernetes. 🔗 Stay Connected: 👉 LinkedIn: https://linkedin.com/in/varun-joshi-2b516752 👉 GitHub: https://github.com/CloudWithVarJosh 💬 Questions?
