How do i find the ecs optimised ami for a particular region?

[petulia3478]

These are AMI that have software preinstalled like docker and the ecs agent.

This command lists the AMI for the us-east-1 region.

$ aws ssm get-parameters --names /aws/service/ecs/optimized-ami/amazon-linux/recommended --region us-east-1
{
    "InvalidParameters": [], 
    "Parameters": [
        {
            "Version": 3, 
            "Type": "String", 
            "Name": "/aws/service/ecs/optimized-ami/amazon-linux/recommended", 
            "Value": "{\"schema_version\":1,\"image_name\":\"amzn-ami-2017.09.l-amazon-ecs-optimized\",\"image_id\":\"ami-aff65ad2\",\"os\":\"Amazon Linux\",\"ecs_runtime_version\":\"Docker version 17.12.1-ce\",\"ecs_agent_version\":\"1.17.3\"}"
        }
    ]
}

To obtain just the ami id.

$ aws ssm get-parameters --names /aws/service/ecs/optimized-ami/amazon-linux/recommended/image_id --region us-east-1 --query "Parameters[0].Value"

"ami-aff65ad2"
