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: When you terminate an ECS container instance, the instance will automatically drain running ECS tasks to another instance in the cluster.
  2. What are the types of EC2 Auto Scaling life cycle hooks you can receive?
  3. What type of responses can you send once you have finished processing EC2 Auto Scaling life cycle hooks?
  4. True/false: EC2 Auto Scaling life cycle hooks can publish events to AWS Kinesis.
  5. You create a Lambda function that processes a life cycle hook and drains your ECS container instances.  You have noticed that sometimes this takes around 4 – 5 minutes, but often takes 15 minutes.  What can you do to resolve this issue?
  1. What CloudFormation feature can you configure to enable rolling updates for Auto Scaling groups?
  2. You want to perform rolling updates and ensure that you always have at least the current desired count of instances in service during the update. How would you achieve this?
  3. When using CloudFormation to subscribe a Lambda function to an SNS topic, what type...
