Overview of this book

Containerization is one of the best ways to implement DevOps, and learning how to execute it effectively is an essential part of a developer’s skillset. Kubernetes is the current industry standard for container orchestration. This book will help you discover the efficiency of managing applications running on Kubernetes with Helm. Starting with a brief introduction to Helm and its impact on users working with containers and Kubernetes, you’ll delve into the primitives of Helm charts and their architecture and use cases. From there, you’ll understand how to write Helm charts in order to automate application deployment on Kubernetes and work your way toward more advanced strategies. These enterprise-ready patterns are focused on concepts beyond the basics so that you can use Helm optimally, looking at topics related to automation, application development, delivery, lifecycle management, and security. By the end of this book, you’ll have learned how to leverage Helm to build, deploy, and manage applications on Kubernetes.

Technical requirements

This chapter requires the following tools:

  • minikube
  • kubectl
  • Helm
  • Git

We will use minikube to explore several examples throughout this chapter, so feel free to start your minikube environment by running the following command:

$ minikube start

Once minikube has started, create a new namespace for this chapter, like so:

$ kubectl create namespace chapter6

If you have not already cloned the example Git repository in previous chapters, do so by running the following command:

$ git clone https://github.com/PacktPublishing/Managing-Kubernetes-Resources-using-Helm.git

Now that your environment is set up, let’s explore this chapter’s first topic—Helm templating.
