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.

Custom Jenkins images

So far, we have used the Jenkins images pulled from the internet. We used jenkins for the master container and evarga/jenkins-slave for the slave container. However, we may want to build our own images to satisfy the specific build environment requirements. In this section, we cover how to do it.

Building Jenkins slave

Let's start from the slave image, because it's more often customized. The build execution is performed on the agent, so it's the agent that needs to have the environment adjusted to the project we would like to build. For example, it may require the Python interpreter if our project is written in Python. The same is applied to any library, tool, testing framework, or anything...
