Managing Kubernetes Resources Using Helm - Second Edition

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.

Installing Argo CD

Argo CD can be installed in Kubernetes by using a set of manifest files or by installing a Helm chart. Of course, we will choose to install Argo CD using the community-provided Helm chart.

The repository URL for the Argo CD Helm chart is https://argoproj.github.io/argo-helm (which can be found in Artifact Hub, a process described in Chapter 3, Installing Your First App with Helm).

Let’s add this repository using the Helm CLI:

$ helm repo add argo https://argoproj.github.io/argo-helm

Once the repository has been added, you can install it. We have provided a values file you can use for the installation in the Packt repository at https://github.com/PacktPublishing/Managing-Kubernetes-Resources-using-Helm/blob/main/chapter10/argo-values/values.yaml. The provided values file disables Dex (an OpenID Connect provider), along with Argo’s notification system, since we will not be using these components in this chapter.
