The DevOps 2.4 Toolkit

By: Viktor Farcic

Overview of this book

Building on The DevOps 2.3 Toolkit: Kubernetes, Viktor Farcic brings his latest exploration of the Docker technology as he records his journey to continuously deploying applications with Jenkins into a Kubernetes cluster. The DevOps 2.4 Toolkit: Continuously Deploying Applications with Jenkins to a Kubernetes Cluster is the latest book in Viktor Farcic’s series that helps you build a full DevOps Toolkit. This book guides readers through the process of building, testing, and deploying applications through fully automated pipelines. Within this book, Viktor will cover a wide-range of emerging topics, including an exploration of continuous delivery and deployment in Kubernetes using Jenkins. It also shows readers how to perform continuous integration inside these clusters, and discusses the distribution of Kubernetes applications, as well as installing and setting up Jenkins. Work with Viktor and dive into the creation of self-adaptive and self-healing systems within Docker.

Being able to package applications is of no use unless we can distribute them. A Kubernetes application is a combination of one or more container images and YAML files that describe them. If we are to distribute our applications, we need to store both container images and YAML definitions in repositories.

We are already storing our images in Docker Hub ( We could have chosen a different container registry but, since Docker Hub is so convenient, we'll continue using it throughout the book. Even though that might not be the best choice, if we move the discussion about repositories for container images out of the way, we can focus on YAML files or, to be more concrete, Helm Charts.

At this point, you might be thinking that being able to run Charts located on your laptop is an excellent way to go. All you have to do...
