Docker High Performance. - Second Edition

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.

Guide to Optimization

The techniques specified in this chapter are not comprehensive; more ways to achieve these objectives will surely be found as more people discover how to use Docker for their applications. More techniques will also arise as Docker itself matures and develops more features. The most important guiding factor for these optimizations is to ask ourselves whether we are really getting the benefits of using Docker. Some good example questions to ask are as follows:

  • Is deploy time improving?
  • Is the development team getting feedback fast enough from the operations team based on what the operations team learned when running our application?
  • Are we able to iterate on new features fast enough to incorporate the new feedback that we discovered from customers using our application?

By keeping in mind our motivation and objective for using Docker, we can come up with our own ways to improve our workflows.
