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.

Configuring Jenkins Kubernetes plugin with ServiceAccounts

Now that we got a grip on ServiceAccounts, it should be relatively straightforward to correct the problem we experienced with Jenkins. As a reminder, we could not configure the Kubernetes plugin. We experienced the same forbidden message as when we tried to use kubectl container with the default ServiceAccount. Now that we know that ServiceAccounts provide permissions to processes running inside containers, all we have to do is to define one for Jenkins.

We'll spice it up a bit with a slightly more complicated use-case. We'll try to run Jenkins master in one Namespace and perform builds in another. That way we can have a clear separation between Jenkins and "random" stuff our builds might be doing. Through such separation, we can guarantee that Jenkins will (probably) not be affected if we do something...
