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.

Summary


Remember that logging in to Docker hosts isn't scalable. Adding instrumentation at the application level, in addition to along with the ones given by our operating system, helps with faster and more efficient diagnosing of the problems that we may encounter in the future. Remember, nobody likes waking up at two in the morning to run tcpdump to debug a Docker container on fire!

In the next chapter, we will wrap up and look again at what it takes to get our Docker-based workloads to production.
