**Example 1: To describe a cluster** The following ``describe-clusters`` example retrieves details about the specified cluster. :: aws ecs describe-clusters \ --cluster default Output:: { "clusters": [ { "status": "ACTIVE", "clusterName": "default", "registeredContainerInstancesCount": 0, "pendingTasksCount": 0, "runningTasksCount": 0, "activeServicesCount": 1, "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/default" } ], "failures": [] } For more information, see `Amazon ECS Clusters <https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ECS_clusters.html>`__ in the *Amazon ECS Developer Guide*. **Example 2: To describe a cluster with the attachment option** The following ``describe-clusters`` example specifies the ATTACHMENTS option. It retrieves details about the specified cluster and a list of resources attached to the cluster in the form of attachments. When using a capacity provider with a cluster, the resources, either AutoScaling plans or scaling policies, will be represented as asp or as_policy ATTACHMENTS. :: aws ecs describe-clusters \ --include ATTACHMENTS \ --clusters sampleCluster Output:: { "clusters": [ { "clusterArn": "arn:aws:ecs:af-south-1:123456789222:cluster/sampleCluster", "clusterName": "sampleCluster", "status": "ACTIVE", "registeredContainerInstancesCount": 0, "runningTasksCount": 0, "pendingTasksCount": 0, "activeServicesCount": 0, "statistics": [], "tags": [], "settings": [], "capacityProviders": [ "sampleCapacityProvider" ], "defaultCapacityProviderStrategy": [], "attachments": [ { "id": "a1b2c3d4-5678-901b-cdef-EXAMPLE22222", "type": "as_policy", "status": "CREATED", "details": [ { "name": "capacityProviderName", "value": "sampleCapacityProvider" }, { "name": "scalingPolicyName", "value": "ECSManagedAutoScalingPolicy-3048e262-fe39-4eaf-826d-6f975d303188" } ] } ], "attachmentsStatus": "UPDATE_COMPLETE" } ], "failures": [] } For more information, see `Amazon ECS Clusters <https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ECS_clusters.html>`__ in the *Amazon ECS Developer Guide*.
