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.

Performing web operations

Keeping a web application running 24/7 on the internet poses challenges in both software development and systems administration. Docker positions itself as the glue that allows both disciplines to come together by creating Docker images that can be built and deployed in a consistent manner.

However, Docker is not a silver bullet for the web. It is still important to know the fundamental concepts in software development and systems administration as web applications become more complex. The complexity naturally arises because these days, with internet technologies in particular, the multitude of web applications is becoming more ubiquitous in people's lives.

Dealing with the complexity of keeping web applications up and running involves mastering the ins and outs of web operations, and like any road to mastery, Theo Schlossnagle boils it down to four basic pursuits: knowledge, tools, experience, and discipline. Knowledge refers to absorbing information about web operations...
