**Example 1: To create a new cluster**

The following ``create-cluster`` example creates a cluster named ``MyCluster`` and enables CloudWatch Container Insights with enhanced observability. ::

    aws ecs create-cluster \
        --cluster-name MyCluster \
        --settings name=containerInsights,value=enhanced


Output::

    {
        "cluster": {
            "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster",
            "clusterName": "MyCluster",
            "status": "ACTIVE",
            "registeredContainerInstancesCount": 0,
            "pendingTasksCount": 0,
            "runningTasksCount": 0,
            "activeServicesCount": 0,
            "statistics": [],
            "settings": [
                {
                    "name": "containerInsights",
                    "value": "enhanced"
                }
            ],
            "tags": []
        }
    }

**Example 2: To create a new cluster using capacity providers**

The following ``create-cluster`` example creates a cluster and associates two existing capacity providers with it. The ``create-capacity-provider`` command is used to create a capacity provider. Specifying a default capacity provider strategy is optional, but recommended. In this example, we create a cluster named ``MyCluster`` and associate the ``MyCapacityProvider1`` and ``MyCapacityProvider2`` capacity providers with it. A default capacity provider strategy is specified that spreads the tasks evenly across both capacity providers. ::

    aws ecs create-cluster \
        --cluster-name MyCluster \
        --capacity-providers MyCapacityProvider1 MyCapacityProvider2 \
        --default-capacity-provider-strategy capacityProvider=MyCapacityProvider1,weight=1 capacityProvider=MyCapacityProvider2,weight=1 

Output::

**Example 3: To create a new cluster with multiple tags**

The following ``create-cluster`` example creates a cluster with multiple tags.  For more information about adding tags using shorthand syntax, see `Using Shorthand Syntax with the AWS Command Line Interface <https://docs.aws.amazon.com/cli/latest/userguide/cli-usage-shorthand.html>`__ in the *AWS CLI User Guide*. ::

    aws ecs create-cluster \
        --cluster-name MyCluster \
        --tags key=key1,value=value1 key=key2,value=value2 

Output::

   {
       "cluster": {
           "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster",
