Docker on Amazon Web Services

By: Justin Menga

Overview of this book

Over the last few years, Docker has been the gold standard for building and distributing container applications. Amazon Web Services (AWS) is a leader in public cloud computing, and was the first to offer a managed container platform in the form of the Elastic Container Service (ECS). Docker on Amazon Web Services starts with the basics of containers, Docker, and AWS, before teaching you how to install Docker on your local machine and establish access to your AWS account. You'll then dig deeper into the ECS, a native container management platform provided by AWS that simplifies management and operation of your Docker clusters and applications for no additional cost. Once you have got to grips with the basics, you'll solve key operational challenges, including secrets management and auto-scaling your infrastructure and applications. You'll explore alternative strategies for deploying and running your Docker applications on AWS, including Fargate and ECS Service Discovery, Elastic Beanstalk, Docker Swarm and Elastic Kubernetes Service (EKS). In addition to this, there will be a strong focus on adopting an Infrastructure as Code (IaC) approach using AWS CloudFormation. By the end of this book, you'll not only understand how to run Docker on AWS, but also be able to build real-world, secure, and scalable container platforms in the cloud.

Creating an EKS cluster

Now that you have a solid understanding of Kubernetes and have defined the core resources required to deploy and run the todobackend application locally, it is time to shift our attention to the Elastic Kubernetes Service (EKS).

The core resource supported by EKS is the EKS cluster, which represents a fully managed, highly available cluster of Kubernetes managers that take care of the Kubernetes control plane for you. In this section, we will focus on creating an EKS cluster in AWS, establishing authentication and access to the cluster, and deploying the Kubernetes dashboard.

Creating an EKS cluster consists of the following primary tasks:

  • Install client components: In order to manager your EKS cluster, you need to install various client components, including kubectl (which you have already installed) and the AWS IAM authenticator for Kubernetes tool.
  • Create cluster resources: This establishes the control plane component of Kubernetes, which consists of Kubernetes masters...
