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 ECS service

We have created an ECS cluster and configured an ECS task definition that includes a single container running Nginx with an appropriate port mapping configuration to expose the Nginx web server to the outside world.

We now need to define an ECS service, which will configure ECS to deploy one or more instances of our ECS task definition to our ECS cluster. ECS services deploy a given ECS task definition to a given ECS cluster, allowing you to configure how many instances (ECS tasks) of the referenced ECS task definition you would like to run, and controlling more advanced features, such as load balancer integration and rolling updates of your application.

To create a new ECS service, complete the following steps:

  1. In the ECS console, select Clusters from the left and click on the test-cluster you created earlier in this chapter:
