Book Description

Amazon Fargate is new launch type for the Amazon Elastic Container Service (ECS). ECS is an AWS service for Docker container orchestration. Docker is the de facto containerization framework and has revolutionized packaging and deployment of software. The introduction of Fargate has made the ECS platform serverless.

The book takes you through how Amazon Fargate runs ECS services composed of tasks and Docker containers and exposes the containers to the user. Fargate has simplified the ECS platform. We will learn how Fargate creates an Elastic Network Interface (ENI) for each task and how auto scaling can be enabled for ECS tasks.

You will also learn about using an IAM policy to download Docker images and send logs to CloudWatch.

Finally, by the end of this book, you will have learned about how to use ECS CLI to create an ECS cluster and deploy tasks with Docker Compose.

What you will learn

• Running Docker containers with a managed service
  
  


• Use Amazon ECS in Fargate launch mode
  
  


• Configure CloudWatch Logging with Fargate
  
  


• Use an IAM Role with Fargate
  
  


• Understand how ECS CLI is used with Fargate
  
  


• Learn how to use an Application Load Balancer with Fargate

Preface

At AWS re:Invent 2017, a new launch type for containers called Fargate was announced. This book is about Amazon Fargate, the new launch type for the Amazon Elastic Container Service (ECS) for Docker containers.

Docker is the de factostandard containerization framework that has revolutionized packaging and deployment of software. Amazon Fargate has made the ECS platform serverless; no EC2 instances to provision, run, or manage. Amazon Fargate runs ECS services on Docker containers and exposes the service tasks directly to the user. Fargate has much simplified the ECS platform by making it serverless.

Amazon Fargate provides the following benefits:

It's s

upported on AWS ECS, with support to be added on AWS EKS

It's f

ully integrated with the other AWS services, including IAM, CloudWatch Logs, and EC2 Load Balancing

Amazon Fargate is serverless and reduces management of ECS clusters; no EC2 instances to provision, create, or manage

ECS service tasks are directly exposed to user

An Elastic Network Interface is created for each task

There's support for the auto scaling of ECS tasks

An ECS CLI is provided to create ECS clusters and deploy tasks with Docker Compose

Instead of launching ECS clusters on EC2 instances, Amazon Fargate launches clusters on the Fargate platform.

Who this book is for

The primary audience is Docker users and developers. Also, if you occupy any of the following roles, you will find this book useful:

DevOps architect

Docker specialist

DevOps engineer (Docker)

What this book covers

Chapter 1, Getting Started with Amazon ECS and Amazon Fargate, is an introductory chapter in which we discuss the benefits of using the Fargate launch type, how compute resources are distributed and configured with Fargate launch type, the ECS objects in Fargate that are the same as for the EC2 launch type, and the new features in Fargate.

Chapter 2, Networking, introduces the Fargate launch type as used with an ECS cluster. We will create a cluster, including container, task, and service definitions, using a Hello World Docker image. Subsequently, we will invoke the Hello World application using the IPv4 Public IP of the Elastic Network Interface associated with a task. 

Chapter 3, Using CloudWatch Logs, discusses configuring an ECS container for logging. We demonstrated CloudWatch Logs using an ECS service for MySQL database. The only supported log driver for the Fargate launch type is the awslogs driver. 

Chapter 4, Using Auto Scaling, introduces ECS service auto scaling as used with the Fargate launch type. Configuring auto scaling involves setting a range (minimum and maximum) for a number of tasks, within which auto scaling is applied.

Chapter 5, Using IAM, discusses configuring an IAM user for ECS. The root user does not require any permissions configuration and has access to the ECS resources, ECS Console, ECS API, and all the required AWS services. If an IAM user is to be used with ECS, the required IAM policies must be added to the IAM user.

Chapter 6, Using an Application Load Balancer, discusses configuring an ECS service with the Fargate launch type with an application load balancer to balance the HTTP requests for a Hello World service. 

Chapter 7, Using Amazon ECS CLI , discusses using the ECS CLI to create a cluster of the Fargate launch type. Then, we will deploy a Docker Compose file on the cluster to run a task for a WordPress Docker image. 

To get the most out of this book

You should have prior knowledge of Docker, as the Fargate platform is a launch mode for Amazon ECS, a managed service for Docker containers. You should also have some prior knowledge of AWS and ECS. 

If you do not already have one, you will need to create an AWS account at https://aws.amazon.com/resources/create-account/.
