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.

Questions


  1. True/false: The default Docker network configuration uses iptables to perform network address translation.
  2. You have an application that forms application-level clusters and uses EC2 metadata to discover the IP addresses of other hosts running your application. When you run your application using ECS, you notice that your applications are using a 172.16.x.x/16 address but your EC2 instances are configured with an 172.31.x.x/16 address. Which Docker network modes could help resolve this problem?
  3. True/false: The host value for NetworkMode in your ECS task definitions enables ECS task networking.
  1. You enable ECS task networking for an ECS task definition, however your application load balancers can no longer reach your application. You check the rules on the security group attached to your ECS container instance and confirm that your load balancers are permitted access to your application. How can you resolve this issue?
