How do i create a ecs cluster using aws cli?

Instead of using the high level ecs-cli commands, you can use the aws cli as well.

$ aws ecs create-cluster --cluster-name AppClus  
{
    "cluster": {
        "status": "ACTIVE", 
        "statistics": [], 
        "clusterName": "AppClus", 
        "registeredContainerInstancesCount": 0, 
        "pendingTasksCount": 0, 
        "runningTasksCount": 0, 
        "activeServicesCount": 0, 
        "clusterArn": "arn:aws:ecs:eu-west-1:123456789012:cluster/AppClus"
    }
}

List the ECS clusters.

$ aws ecs list-clusters                             
{
    "clusterArns": [
        "arn:aws:ecs:eu-west-1:123456789012:cluster/default"
    ]
}

AWS uses the default cluster when just provisioning instances with the ecs agent preinstalled. AWS provide ECS optimised EC2 AMI's for various regions.
