```for i in ap-northeast-1 ap-northeast-2 ap-south-1 ap-southeast-1 ap-southeast-2 ca-central-1 eu-central-1 eu-west-1 eu-west-2 eu-west-3 sa-east-1 us-east-1 us-east-2 us-west-1 us-west-2 ;do echo -n "\"$i\": "; aws ssm get-parameters --names /aws/service/ecs/optimized-ami/amazon-linux/recommended --region $i |jq '.Parameters[0]'.Value|sed s/[\\]//g |sed s/^\"//|sed s/\"$// |jq '.image_id' ;done```
