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.

Other container debugging tools


Debugging applications inside Docker containers requires a different approach from normal applications in Linux. However, the actual programs being used are the same because all of the calls from inside the container will eventually go to the Docker host's kernel operating system. By knowing how calls go outside of our containers, we can use any other debugging tools we have to troubleshoot.

In addition to standard Linux tools, there are several container-specific utilities that package the preceding standard utilities to be more friendly for container usage. The following are some of these tools:
