Part 4. Docker in production

At last we’re ready to contemplate running Docker in production. In part 4 we address the key operational considerations when running Docker on live environments. Chapter 9 covers the burgeoning area of orchestration. As soon as you run any number of containers in the same environment, you’ll need to think about how they’re managed in a consistent and reliable way, so we’ll look at some of the most popular tools currently available. Security is the focus of chapter 10. Through practical techniques you’ll get a real understanding of the security challenges Docker brings and how you might want to address them. Backups, logging and resource management are considered in chapter 11, where we show you how these traditional sysadmin tasks can be managed with in a Docker context. Finally, in chapter 12 we look at what to do when things go wrong, covering some common areas where Docker can get into trouble, as well as how to debug containers in production.
