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.

Setting up your environment

In this chapter, we will create and run a series of tests for the Guestbook chart created in the previous chapter. Run the following steps to set up your minikube environment, where we will test the Guestbook chart:

  1. Start minikube by running the minikube start command:
    minikube start
  2. Then, create a new namespace called chapter6:
    kubectl create namespace chapter6

With your minikube environment ready, let's begin by discussing how Helm charts can be tested. We will begin the discussion by outlining the methods you can use to verify your Helm templates.
