➜  ~ aws service-quotas list-aws-default-service-quotas --service-code ecs  --region eu-west-1 --query "Quotas[*].{ServiceName:ServiceName,QuotaName:QuotaName,QuotaCode:QuotaCode,Value:Value}" --output table

I've AWS CLI version

➜  ~ aws --version
aws-cli/1.18.64 Python/3.7.4 Linux/4.14.138-114.102.amzn2.x86_64 botocore/1.16.14

Could you please confirm list-service-quotas is blank...
Any Suggestions here please ?

The reason for this is because there are two types of quotas - default quotas and applied quotas. Default quotas show you the default value for all AWS accounts. Applied quotas show your accounts specific quota, which would be different than the default quota if you've requested and been granted a quota increase.

When you list the service quotas for a specific service, you are viewing your applied quotas. When you list the AWS default services quotas, you are viewing the default quotas. At the current time, Amazon ECS does not support applied quotas which is why that API returns an empty value.

I hope this clears this up. Once Amazon ECS supports applied quotas, we will update the documentation to reflect this.
