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.

Adding CodeBuild support to your application repository


Whenever you create a CodeBuild project, you must define how CodeBuild should test and build your application source code, and then publish application artifacts and/or Docker images. CodeBuild defines these tasks within a build specification, which provides the build instructions the CodeBuild agent should execute when running a build.

CodeBuild allows you to provide a build specification in several ways:

  • Self-defined: CodeBuild looks for a file that is defined within the source repository of the project.  By default, this is a file called buildspec.yml; however, you can also configure a custom file where your build specification is located.
  • Preconfigured: When you create a CodeBuild project, you can define a build specification as part of your project setup.
  • On demand: If you initiate a CodeBuild build job using the AWS CLI or SDK, you can override the preconfigured or self-defined build specification

In general, I recommend using the...
