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.

Understanding CI/CD and GitOps

So far, we have addressed many of the key concepts that are inherent to Helm development—building, testing, and deploying. However, our exploration has been limited to manual configurations and invocations of the Helm CLI. While this is okay when getting started with Helm, as you look to move a chart into a production-like environment, there are several questions that you need to consider, including the following:

  • How can I be sure that the best practices for chart development and deployment are enforced?
  • What are the implications of collaborators participating in the development and deployment processes?

These points are applicable to any software project, not just to Helm chart development. While we have covered a lot of best practices so far, when taking on new collaborators, they may not have the same understanding of these topics or the discipline to perform these crucial steps. Through the use of automation and repeatable...
