Learn Helm: Improve productivity, reduce complexity, and speed up cloud-native adoption with Helm for Kubernetes

Kubernetes makes it possible to run complex applications across a cluster—but keeping their configuration, releases, and lifecycle in order takes more than a collection of resource files. Learn Helm shows how Helm helps bring those moving parts together, beginning with Kubernetes fundamentals and progressing toward creating and managing charts of your own.

Andrew Block and Austin Dewey take a practical, step-by-step approach. Readers first prepare a Kubernetes and Helm environment, then work through a WordPress deployment before moving into chart structure, templates, dependencies, and lifecycle hooks. The result is a grounded introduction to Helm for people who want to understand both how to use charts and how to build them.

Start with Kubernetes, then make sense of Helm

The opening section explains Kubernetes resources and application deployment, including the challenges of keeping local configuration aligned with what is running in a cluster. That context helps clarify the role Helm plays: managing applications as releases and making configuration easier to reuse and update.

Follow a deployment from setup to rollback

Readers prepare a local environment using tools including Minikube and kubectl, configure Helm, and install a WordPress chart. The example explores chart discovery, values files, installation, inspection, upgrades, and rollback—giving Helm commands a concrete purpose rather than presenting them in isolation.

Explore how Helm charts are put together

The chart-development section covers YAML, Go templates, chart definitions, dependencies, and values. It also examines hooks and chart documentation. Together, these topics show how charts can be structured to make Kubernetes applications configurable and easier to package and manage.

For Kubernetes developers and administrators

This book is aimed at developers and administrators interested in using Helm to automate application deployment on Kubernetes. Previous Helm experience is not required; a basic understanding of Kubernetes application development is useful.

If you are ready to move from manually handling Kubernetes resources toward repeatable chart-based deployments, Learn Helm offers a practical route from first installation to chart authoring.
