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.

Chapter 7: Automating Helm Processes Using CI/CD and GitOps

Here are some answers to the questions presented in this chapter:

  1. CI is an automated software development process that can be repeated when a software change occurs. CD is a set of defined steps written to progress software through a release process (commonly referred to as a pipeline).
  2. While CI/CD describes the software development and release process, GitOps describes the act of storing configuration in Git. An example of this is storing a values file in Git, which can be applied to deploy an application to Kubernetes.
  3. A CI pipeline for creating and releasing Helm charts can lint, install, and test the Helm charts. The Chart testing tool can help perform these steps more easily, especially when maintaining a chart monorepo. The pipeline should also package each Helm chart and deploy the charts to the chart repository. For GitHub Pages chart repositories, the index.yaml file must be generated, and the contents...
