Helm Tutorial

16 Chapters Beginner to Advanced Estimated Time: 18–22 hours

What is This Tutorial?

If you’ve ever deployed an application to Kubernetes, you know the pain — a Deployment YAML, a Service YAML, a ConfigMap, an Ingress, maybe a PersistentVolumeClaim. For a single app, that’s 5+ files. Now multiply that by 10 microservices across 3 environments.

That’s where Helm comes in.

Helm is the package manager for Kubernetes. Just like apt manages packages on Ubuntu or brew on macOS, Helm manages applications on Kubernetes. It bundles all your YAML files into a single chart, adds templating so you can customize values per environment, and tracks releases so you can upgrade, rollback, and manage your deployments with simple commands.

This tutorial takes you from zero Helm knowledge to confidently creating, managing, and deploying Helm charts in production.
