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.

Creating Namespaces dedicated to continuous deployment processes

If we are to accomplish a reasonable level of security of our pipelines, we need to run them in dedicated Namespaces. Our cluster already has RBAC enabled, so we'll need a ServiceAccount as well. Since security alone is not enough, we also need to make sure that our pipeline does not affect other applications. We'll accomplish that by creating a LimitRange and a ResourceQuota.

I believe that in most cases we should store everything an application needs in the same repository. That makes maintenance much simpler and enables the team in charge of that application to be in full control, even though that team might not have all the permissions to create the resources in a cluster.

We'll continue using go-demo-3 repository but, since we'll have to change a few things, it is better if you apply the...
