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.

Upgrading Charts

We are about to install the go-demo-3 Chart. You should already be familiar with the commands, so you can consider this as an exercise that aims to solidify what you already learned. There will be one difference when compared to the commands we executed earlier. It'll prove to be a simple, and yet an important one for our continuous deployment processes.

We'll start by inspecting the values.

 1  helm inspect values helm/go-demo-3
