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 production releases

We are ready to create our first production release. We trust our tests, and they proved that it is relatively safe to deploy to production. Since we cannot deploy to air, we need to create a production release first.

We will not rebuild the image. The artifact we produced (our Docker image) and confirmed through our tests, is the one we care for. Rebuilding would not only be a waste, and it could potentially be a different artifact than the one we tested. That must never happen!

Please make sure to replace [...] with your Docker Hub user in one of the commands that follow.

 1  kubectl -n go-demo-3-build \
 2      exec -it cd -c docker -- sh
3 4 export DH_USER=[...] 5 6 docker image tag \
7 $DH_USER/go-demo-3:1.0-beta \

 8  $DH_USER/go-demo-3:1.0
10 docker image push \
11 $DH_USER/go-demo-3:1.0

We went back to the docker container...
