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.

To continuously deploy or to continuously deliver?

Should we use the continuous deployment (CDP) or the continuous delivery (CD) process? That's a hard question to answer which mainly depends on your internal processes. There are a few questions that might guide us.

  4. Are those teams self-sufficient and do not depend on other teams?
  5. Do you really want to upgrade production with every commit to the master branch?

If you answered with no to at least one of those questions, you cannot do continuous deployment. You should aim for continuous...
