Course Overview

This course deals with Helm, the Kubernetes Package Manager. Helm simplifies the deployment and management of applications on Kubernetes by packaging them into charts — collections of pre-configured Kubernetes resources.

Students will learn to install and use Helm, work with public and private chart repositories, install and manage releases, create and customise charts, write templates with values and pipelines, and extend Helm with plugins.
