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.

Understanding CI/CD and GitOps

So far, we have addressed manually invoking the Helm CLI to install and manage Helm charts. While this is acceptable when getting started with Helm, as you look to manage a chart in a production-like environment, there are questions that you need to consider, including the following:

  • How can I be sure that the best practices for Helm chart deployments are enforced?
  • What are the implications for collaborators participating in the deployment process?

You may be familiar with the best practices and processes around deploying Helm charts; however, any new collaborators or team members may not have the same level of knowledge or expertise. Not to mention, you may become limited in the level of support that you can provide to others as your responsibilities among the number of applications you manage increases. Through the use of automation and repeatable processes, we can address these challenges.
