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 nodes for building container images

We already discussed that mounting a Docker socket is a bad idea due to security risks. Running Docker in Docker would require privileged access, and that is almost as unsafe and Docker socket. On top of that, both options have other downsides. Using Docker socket would introduce processes unknown to Kubernetes and could interfere with its scheduling capabilities. Running Docker in Docker could mess up with networking. There are other reasons why both options are not good, so we need to look for an alternative.

Recently, new projects spun up attempting to help with building container images. Good examples are img (, orca-build (, umoci (, buildah (, FTL (
