Calling the ECS optimized AMI public parameter in Parameter Store

The Amazon Elastic Container Service (Amazon ECS) service publishes the name of the latest Amazon ECS optimized Amazon Machine Images (AMIs) as public parameters. Users are encouraged to use this AMI when creating a new Amazon Elastic Compute Cloud (Amazon EC2) cluster for Amazon ECS because the optimized AMIs include bug fixes and feature updates.

Use the following command to view the name of the latest Amazon ECS optimized AMI for Amazon Linux 2. To see commands for other operating systems, see Retrieving Amazon ECS-Optimized AMI metadata in the Amazon Elastic Container Service Developer Guide.

Linux & macOS
aws ssm get-parameters \
    --names /aws/service/ecs/optimized-ami/amazon-linux-2/recommended
Windows
aws ssm get-parameters ^
    --names /aws/service/ecs/optimized-ami/amazon-linux-2/recommended

The command returns information like the following.
