Continuous Delivery with Docker and Jenkins, 3rd Edition - Third Edition

By: Rafał Leszko

Overview of this book

This updated third edition of Continuous Delivery with Docker and Jenkins will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of app development. You’ll start by setting up a Docker server and configuring Jenkins on it. Next, you’ll discover steps for building applications and microservices on Dockerfiles and integrating them with Jenkins using continuous delivery processes such as continuous integration, automated acceptance testing, configuration management, and Infrastructure as Code. Moving ahead, you'll learn how to ensure quick application deployment with Docker containers, along with scaling Jenkins using Kubernetes. Later, you’ll explore how to deploy applications using Docker images and test them with Jenkins. Toward the concluding chapters, the book will focus on missing parts of the CD pipeline, such as the environments and infrastructure, application versioning, and non-functional testing. By the end of this continuous integration and continuous delivery book, you’ll have gained the skills you need to enhance the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Installing Ansible

Ansible is an open source, agentless automation engine for software provisioning, configuration management, and application deployment. Its first release was in 2012, and its basic version is free for both personal and commercial use. The enterprise version is called Ansible Tower, which provides GUI management and dashboards, the REST API, role-based access control, and some more features.

We will present the installation process and a description of how Ansible can be used separately, as well as in conjunction with Docker.

Ansible server requirements

Ansible uses the SSH protocol for communication and has no special requirements regarding the machine it manages. There is also no central master server, so it's enough to install the Ansible client tool anywhere; we can then use it to manage the whole infrastructure.

Information

The only requirement for the machines being managed is to have the Python tool (and...
