Learn Helm

Overview of this book

Containerization is currently known to be one of the best ways to implement DevOps. While Docker introduced containers and changed the DevOps era, Google developed an extensive container orchestration system, Kubernetes, which is now considered the frontrunner in container orchestration. With the help of this book, you’ll explore the efficiency of managing applications running on Kubernetes using Helm. Starting with a short introduction to Helm and how it can benefit the entire container environment, you’ll then delve into the architectural aspects, in addition to learning about Helm charts and its use cases. You’ll understand how to write Helm charts in order to automate application deployment on Kubernetes. Focused on providing enterprise-ready patterns relating to Helm and automation, the book covers best practices for application development, delivery, and lifecycle management with Helm. By the end of this Kubernetes book, you will have learned how to leverage Helm to develop an enterprise pattern for application delivery.

Preparing a local Kubernetes environment with Minikube

Helm won't be able to deploy applications without access to a Kubernetes cluster. For this reason, let's discuss one option that users can follow to run their own cluster on their machine—Minikube.

Minikube is a community-driven tool that allows users to easily deploy a small, single-node Kubernetes cluster to their local machine. A cluster created with Minikube is created inside a virtual machine (VM), so it can be created and later discarded in a way that is isolated from the host operating system that the VM is running on. Minikube presents an excellent way to experiment with Kubernetes and it can also be used to learn how to use Helm alongside the examples provided throughout this book.

In the next few sections, we'll cover how Minikube can be installed and configured so that you have a Kubernetes cluster available while learning how to use Helm. For more comprehensive instructions, please refer...
