Master the Kubernetes package manager. Learn charts, templating, values, releases, hooks, and real-world deployment patterns — from first install to production CI/CD.
Start Learning →🔰 Basics
Understand what Helm is, why it exists, and the core concepts: charts, releases, and repositories.
What is Helm
Why Helm exists, Helm vs raw YAML, the package manager analogy.
Helm Architecture

Charts
Chart structure, Chart.yaml, templates/, values.yaml, and helpers.
Installing & Managing Releases
helm install, upgrade, rollback, uninstall, and release history.

Template Functions
Built-in functions, pipelines, conditionals, loops, and named templates.

Chart dependencies, subcharts, global values, and condition flags.
🚀 Advanced
Build production-grade charts, leverage lifecycle hooks, and integrate Helm into CI/CD pipelines.
Creating Custom Charts
Scaffold, structure, best practices, linting, packaging, and publishing.
Hooks & Tests
Pre/post install hooks, upgrade hooks, test hooks, and hook weights.
Helm in CI/CD
Helmfile, GitOps, ArgoCD, GitHub Actions, and environment promotion.
🧪 Hands-on Labs
Practice real deployments, break things on purpose, debug failures, and prepare for interviews.
Deploy with Helm
End-to-end: install a chart, customize values, upgrade, and rollback.
Break & Fix
Intentionally break Helm deployments and learn to diagnose them.
Debugging Scenarios
Failed installs, wrong values, template render errors, upgrade failures.
