Continuous Delivery with Docker and Jenkins - Second Edition

By: Rafał Leszko

Overview of this book

Continuous Delivery with Docker and Jenkins, Second Edition will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of an 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 Kubernetes. Next, you will get to know how to deploy applications using Docker images and testing them with Jenkins. Towards the end, the book will touch base with missing parts of the CD pipeline, which are the environments and infrastructure, application versioning, and nonfunctional testing. By the end of the book, you will be enhancing the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Introducing pipelines


A pipeline is a sequence of automated operations that usually represents a part of the software delivery and quality assurance process. It can be seen as a chain of scripts that provide the following additional benefits:

  • Operation grouping: Operations are grouped together into stages (also known as gates or quality gates) that introduce a structure into the process and clearly define the rule—if one stage fails, no further stages are executed
  • Visibility: All aspects of the process are visualized, which helps in quick failure analysis and promotes team collaboration
  • Feedback: Team members learn about problems as soon as they occur, so that they can react quickly

Note

The concept of pipelining is similar for most Continuous Integration tools. However, the naming can differ. In this book, we stick to the Jenkins terminology.

The pipeline structure

A Jenkins pipeline consists of two kinds of elements—Stage and Step. The following diagram shows how they are used:
