Mastering Docker, Fourth Edition - Fourth Edition

Overview of this book

Docker has been a game changer when it comes to how modern applications are deployed and created. It has now grown into a key driver of innovation beyond system administration, with a significant impact on the world of web development. Mastering Docker shows you how you can ensure that you're keeping up with the innovations it's driving and be sure you're using it to its full potential. This fourth edition not only demonstrates how to use Docker more effectively but also helps you rethink and reimagine what you can achieve with it. You'll start by building, managing, and storing images along with exploring best practices for working with Docker confidently. Once you've got to grips with Docker security, the book covers essential concepts for extending and integrating Docker in new and innovative ways. You'll also learn how to take control of your containers efficiently using Docker Compose, Docker Swarm, and Kubernetes. By the end of this Docker book, you’ll have a broad yet detailed sense of what's possible with Docker and how seamlessly it fits in with a range of other platforms and tools.

Amazon Elastic Kubernetes Service (EKS)

The next Kubernetes service we are going to take a look at is the Amazon Elastic Container Service for Kubernetes, or Amazon EKS for short. This is the most recently launched service of the three services we have covered so far. In fact, you could say that Amazon was very late to the Kubernetes party.

Unfortunately, the command-line tools for Amazon are not as user friendly as the ones we used for Microsoft Azure and Google Cloud. Because of this, we are going to be using a tool called eksctl, which was written by Weave, the same people who created the demo store we have been using. It has been adopted by Amazon as the official command client of EKS, as opposed to the commands built into their own client.

Because of this, we are going to bypass the web-based portal and concentrate on eksctl, which itself makes use of the AWS command-line tools.

Before we install eksctl, we need to install...
