Overview of this book

Docker is the de facto standard for containerizing apps, and with an increasing number of software projects migrating to containers, it is crucial for engineers and DevOps teams to understand how to build, deploy, and secure Docker environments effectively. Docker for Developers will help you understand Docker containers from scratch while taking you through best practices and showing you how to address security concerns. Starting with an introduction to Docker, you’ll learn how to use containers and VirtualBox for development. You’ll explore how containers work and develop projects within them after you’ve explored different ways to deploy and run containers. The book will also show you how to use Docker containers in production in both single-host set-ups and in clusters and deploy them using Jenkins, Kubernetes, and Spinnaker. As you advance, you’ll get to grips with monitoring, securing, and scaling Docker using tools such as Prometheus and Grafana. Later, you’ll be able to deploy Docker containers to a variety of environments, including the cloud-native Amazon Elastic Kubernetes Service (Amazon EKS), before finally delving into Docker security concepts and best practices. By the end of the Docker book, you’ll be able to not only work in a container-driven environment confidently but also use Docker for both new and existing projects.

Spinning up AWS EKS with CloudFormation

Now that we have walked through a local installation of Kubernetes and explored some of the cloud vendor options, we are going to try deploying containers to an AWS-hosted Kubernetes environment. This will be the EKS service we briefly introduced in the previous section of this chapter.

In order to achieve this, we will describe how to create and manage an EKS cluster using AWS CloudFormation, their infrastructure-as-code service. For more information on CloudFormation, be sure to check out the AWS guides and documentation at https://docs.aws.amazon.com/cloudformation/.

Assuming you have previously created an AWS account or followed the instructions under the Technical requirements section of this chapter, load up the AWS cloud console.

To proceed, we need to set up EKS. There are many ways to get a working EKS cluster that require varying amounts of work:

  • Set up everything by hand, step by step through the AWS console. We do...
