Overview of this book

Docker is an enterprise-grade container platform that allows you to build and deploy your apps. Its portable format lets you run your code right from your desktop workstations to popular cloud computing providers. This comprehensive guide will improve your Docker work?ows and ensure your application's production environment runs smoothly. This book starts with a refresher on setting up and running Docker and details the basic setup for creating a Docker Swarm cluster. You will then learn how to automate this cluster by using the Chef server and cookbooks. After that, you will run the Docker monitoring system with Prometheus and Grafana, and deploy the ELK stack. You will also learn best practices for optimizing Docker images. After deploying containers with the help of Jenkins, you will then move on to a tutorial on using Apache JMeter to analyze your application's performance. You will learn how to use Docker Swarm and NGINX to load-balance your application, and how common debugging tools in Linux can be used to troubleshoot Docker containers. By the end of this book, you will be able to integrate all the optimizations that you have learned and put everything into practice in your applications.

Deploying and configuring Jenkins


Jenkins originally started life as an open source build server, originally called Hudson (the name was changed followinga dispute with Oracle), whose sole purpose was to compile Java applications. Since it was first released in 2004, its role has been greatly expanded and it is now considered to be one of the leading continuous integration and continuous delivery solutions available and not just a build server for Java applications.

Before we can deploy our test application, we need to deploy and configure Jenkins. The following are the steps you need to take to get a full Jenkins server deployed and configured.

Deploying the Jenkins container

Before we launch and configure our Jenkins container in our Docker Swarm cluster, we need to create an image. For this, we will be using the official Jenkins image as a base and then we will add a few of our own customizations:

  1. We will start by preparing a Jenkins configuration file; the file should be named init.groovy...
