📚 Welcome to Day 43!
In this lecture, we dive deep into Helm — the most widely used package manager for Kubernetes. While Kustomize focuses on patching YAMLs, Helm helps you template, version, install, upgrade, and rollback entire applications with ease.
Through 3 hands-on demos, we’ll explore how Helm charts can help you manage real-world Kubernetes deployments across multiple environments (dev, stage, and prod), with minimal duplication and maximum control.
📝 What We’ll Cover:
✅ Why Helm is needed in modern Kubernetes environments
✅ Helm vs. Kustomize: key differences and when to use what
✅ Core components: Chart, Repository, Release
✅ Helm templating basics using Go templates
✅ Helm CLI walkthrough: lint, install, upgrade, rollback
✅ Demo 1: Build your own Helm chart from scratch
✅ Demo 2: Perform app upgrades and rollbacks using Helm
✅ Demo 3: Deploy to dev, stage, and prod using values files
✅ Best practices around release naming, values.yaml, and multi-env deployment
✅ How Chart.yaml is used in production setups
💡 By the end of this lecture:
You’ll understand how Helm charts can simplify multi-environment Kubernetes deployments, and how to safely manage the entire app lifecycle — from install to rollback — using a single chart and a few simple commands.
