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.

Technical requirements

This chapter focuses on the integration of Kubernetes with some AWS services, including CloudWatch, Kinesis, and S3, so you must have a working AWS account with administrator privileges. You will need to have a working Kubernetes cluster in AWS, as set up in a previous chapter with AWS Elastic Kubernetes Service (EKS). You could reuse that cluster or set up a new one for this chapter using either the AWS EKS Quick Start CloudFormation templates or eksctl.

You will also need to have a current version of the AWS CLI, kubectl, and helm 3.x installed on your local workstation, as described in the previous chapter. The helm commands in this chapter use the helm 3.x syntax.  The EKS cluster must have a working ALB Ingress Controller setup.

You could use Spinnaker and Jenkins, as set up in previous chapters, to deploy the applications in this chapter, but it is not required.
