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 a custom CodeBuild container


AWS CodeBuild provides a build service that uses a container build agent to execute your builds.  CodeBuild provides a number of AWS curated images that target specific application languages and/or platforms, such as Python, Java, PHP and many more. CodeBuild does provide an image that is designed for building Docker images; however, this image is somewhat limited, in that it does not include tools like the AWS CLI, GNU make, and Docker Compose, all of which we require for building the todobackend application.

Although you can run pre-build steps that install additional tools in CodeBuild, this approach slows down your builds, as the installation of the additional tools will happen on each and every build. CodeBuild does support using your own custom images, which allows you to pre-package all of the tools required for your application builds.

For our use case, the CodeBuild build environment must include the following:

  • Access to a Docker daemon, given...
