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.

Deploying the sample application to Docker Swarm

We are now down to the business end of the chapter, which is to deploy our sample todobackend application to our newly created Docker swarm cluster. As you might expect, there are a few challenges we are going to encounter, which require the following configuration tasks to be performed:

  • Integrating Docker Swarm with the Elastic Container Registry
  • Defining a stack
  • Creating shared storage for hosting static content
  • Creating a collectstatic service
  • Creating persistent storage for storing the todobackend database
  • Secrets management using Docker Swarm
  • Running database migrations

Integrating Docker Swarm with the Elastic Container Registry

The todobackend application is already published in an existing Elastic Container Registry (ECR) repository, and ideally we want to be able to integrate our Docker swarm cluster so that we can pull private images from ECR. As of the time of writing this book, ECR integration is supported in a somewhat limited fashion...
