This assumes you have already configured the aws command line tool. If not, check out my article on Getting Started with the AWS CLI.

The aws ecs list-clusters command can be used to list your Elastic Container Service (ECS) Clusters.

~]$ aws ecs list-clusters
{
    "clusterArns": [
        "arn:aws:ecs:us-east-1:123456789012:cluster/my-ecs-cluster"
    ]
}

And then the aws ecs list-services command can be used to list the services that have been created in the cluster.

]$ aws ecs list-services --cluster arn:aws:ecs:us-east-1:123456789012:cluster/my-ecs-cluster
{
    "serviceArns": [
        "arn:aws:ecs:us-east-1:123456789012:service/my-ecs-cluster/nginx-service"
    ]
}

And then the aws ecs update-service command can be used to update the desired count of containers for the service down to 0.

aws ecs update-service \
--cluster arn:aws:ecs:us-east-1:123456789012:cluster/my-ecs-cluster \
--service arn:aws:ecs:us-east-1:123456789012:service/my-ecs-cluster/nginx-service \
--desired-count 0

And then the aws ecs delete-service command can be used to delete a service that has been scaled down to zero.

aws ecs delete-service \
--cluster arn:aws:ecs:us-east-1:123456789012:cluster/my-ecs-cluster \
--service arn:aws:ecs:us-east-1:123456789012:service/my-ecs-cluster/nginx-service
