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.

Preparing Docker Hosts

Docker allows us to deliver applications to our customers faster. It simplifies the workflows needed to get code from development to production by being able to easily create and launch Docker containers. This chapter will be a quick refresher on how to get our environment ready to run Docker-based development and operations workflow by doing the following:

  • Preparing a Docker host
  • Enabling remote access to Docker hosts
  • Building a Docker Swarm cluster

Most of the parts of this chapter are concepts that we are already familiar with and these  are readily available in the Docker documentation website. This chapter shows selected commands and interactions with the Docker host that will be used in the succeeding chapters.
