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.

Running builds in different Namespaces

One of the significant disadvantages of the script we used inside my-k8s-job is that it runs in the same Namespace as Jenkins. We should separate builds from Jenkins and thus ensure that they do not affect its stability.

We can create a system where each application has two namespaces; one for testing and the other for production. We can define quotas, limitations, and other things we are used to defining on the Namespace level. As a result, we can guarantee that testing an application will not affect the production release. With Namespaces we can separate one set of applications from another. At the same time, we'll reduce the chance that one team will accidentally mess up with the applications of the other. Our end-goal is to be secure without limiting our teams. By giving them freedom in their own Namespace, we can be secure without...
