Amazon Elastic Container Service sample templates - Amazon CloudFormation
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon Elastic Container Service sample templates

Amazon Elastic Container Service (Amazon ECS) is a container management service that makes it easy to run, stop, and manage Docker containers on a cluster of Amazon Elastic Compute Cloud (Amazon EC2) instances.

Create a cluster with the AL2023 Amazon ECS-Optimized-AMI

Define a cluster that uses a capacity provider that launches AL2023 instances on Amazon EC2.

Important

For the latest AMI IDs, see Amazon ECS-optimized AMI in the Amazon Elastic Container Service Developer Guide.
