Book Description

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 industry standard. With the help of this book, you'll explore the efficiency of managing applications running on Kubernetes using 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 its overall 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 towards more advanced strategies. These enterprise-ready patterns are focused on concepts beyond the basics so that you can use Helm optimally, including 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.

What you will learn

• Understand how to deploy applications on Kubernetes with ease
• Package dynamic applications for deployment on Kubernetes
