Get Started with KUBERNETES(Including HELM): Basic to Intermediate

Welcome to Week 10 of my ‘Learn in Public’ journey! 🚀

This week, I’m excited to explore Kubernetes, one of the most powerful tools for managing containerized applications across multiple hosts. Kubernetes automates deployment, scaling, and managing containerized applications, making it a crucial part of the DevOps toolkit.

In this blog, I’ll give you an overview of the key concepts and steps you need to get started with Kubernetes. Whether you’re new to Kubernetes or want to deepen your understanding, this guide will walk you through the fundamentals and intermediate topics to help you manage containers at scale.
