Amazon Fargate Quick Start Guide

By: Deepak Vohra

Overview of this book

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.

Creating an ECS cluster

Having configured the prerequisites, next we shall create an ECS Fargate cluster. Run the following command in PowerShell to create a cluster:

esc-cli up

As the command output indicates, a cluster gets created using the cluster configuration set up earlier. A VPC and two subnets also get created:

PS C:\PowerShell> ecs-cli up
←[36mINFO←[0m[0002] Created cluster ←[36mcluster←[0m=hello-world ←[36mregion←[0m=us-east-1
←[36mINFO←[0m[0003] Waiting for your cluster resources to be created...
←[36mINFO←[0m[0004] Cloudformation stack status ←[36mstackStatus←[0m=CREATE_IN_PROGRESS
←[36mINFO←[0m[0065] Cloudformation stack status ←[36mstackStatus←[0m=CREATE_IN_PROGRESS
 VPC created: vpc-6e021915
 Subnet created: subnet-2c02dd4b
 Subnet created: subnet-f2d50bdc
 Cluster creation succeeded.
 PS C:\PowerShell>

Access the ECS Console in a web browser and the hello-world cluster gets listed, as shown here:
