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: Fargate requires you to create an ECS cluster.
  2. When configuring Fargate, what networking modes are supported?
  3. True/false: Fargate separates ECS agent control plane network communications from ECS task data plane network communications.
  4. You deploy a new ECS service using Fargate, which fails, with an error indicating that the ECR image specified in the task definition cannot be pulled. You verify that the image name and tag are correct, and that the IAM role referenced on the TaskRoleArn property of the task definition permits access to the ECR repository. What is the most likely cause of this error?
  5. You are determining the best technology to deploy your container-based applications in AWS. Your organization deploys Splunk to collect logs for all applications, and uses New Relic to collect performance metrics. Is Fargate a suitable technology, based on these requirements?
  6. True/false: ECS service discovery uses Consul to publish service registration information.
  7. Which service...
