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.

Chapter 4. Introduction to ECS

Elastic Container Service (ECS) is a popular AWS-managed service that provides container orchestration for your applications and integrates with a wide variety of AWS services and tools.

In this chapter, you will learn key concepts of ECS; how ECS is architected, and understand the various components of ECS, which include the Elastic Container Registry (ECR), ECS clusters, ECS container instances, ECS task definitions, ECS tasks, and ECS services. The primary focus of this chapter will be using the AWS console to create your first ECS cluster, define an ECS task definition, and configure an ECS service to deploy your first container application to ECS. You will take a closer look at how ECS clusters are formed from ECS container instances, and inspect an ECS container instance under the hood to understand further how ECS is connected to your infrastructure and how containers are deployed and managed. Finally, you will be introduced to the ECS command-line interface...
