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.

Acceptance testing with Docker Compose

Docker Compose fits the acceptance testing process perfectly because it enables setting up the entire environment with one command. What's more, after the testing is performed, the environment can also be cleaned up with one command. If we decide to use Docker Compose on production, then the other benefit is that the acceptance test uses exactly the same configuration, tools, and commands as the released application.

To see how to apply Docker Compose for the Jenkins acceptance testing stage, let's continue the calculator project example and add the Redis-based caching to the application. Then, we will see two different approaches to run acceptance testing: the Jenkins-first method and the Docker-first method.
