Continuous Delivery with Docker and Jenkins

By: Rafał Leszko

Overview of this book

The combination of Docker and Jenkins improves your Continuous Delivery pipeline using fewer resources. It also helps you scale up your builds, automate tasks and speed up Jenkins performance with the benefits of Docker containerization. This book will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of app development. It will start with setting up a Docker server and configuring Jenkins on it. It will then provide steps to build applications on Docker files and integrate them with Jenkins using continuous delivery processes such as continuous integration, automated acceptance testing, and configuration management. Moving on you will learn how to ensure quick application deployment with Docker containers along with scaling Jenkins using Docker Swarm. Next, you will get to know how to deploy applications using Docker images and testing them with Jenkins. By the end of the book, you will be enhancing the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Advanced Docker Swarm

Docker Swarm offers a lot of interesting features that are useful in the Continuous Delivery process. In this section, we will walk through the most important ones.

Rolling updates

Imagine you deploy a new version of your application. You need to update all replicas in the cluster. One option would be to stop the whole Docker Swarm service and to run a new one from the updated Docker image. Such approach, however, causes downtime between the moment when the service is stopped and the moment when the new one is started. In the Continuous Delivery process, downtime is not acceptable, since the deployment can take place after every source code change, which is simply often. Then, how can we provide zero...
