**To get detailed information about one or more Amazon DocumentDB clusters.** The following ``describe-db-clusters`` example displays details for the Amazon DocumentDB cluster ``sample-cluster``. By omitting the ``--db-cluster-identifier`` parameter you can get information of up to 100 clusters. :: aws docdb describe-db-clusters --db-cluster-identifier sample-cluster Output:: { "DBClusters": [ { "DBClusterParameterGroup": "default.docdb3.6", "Endpoint": "sample-cluster.cluster-corcjozrlsfc.us-west-2.docdb.amazonaws.com", "PreferredBackupWindow": "00:00-00:30", "DBClusterIdentifier": "sample-cluster", "ClusterCreateTime": "2019-03-15T20:29:58.836Z", "LatestRestorableTime": "2019-03-18T20:28:03.239Z", "MasterUsername": "master-user", "DBClusterMembers": [ { "PromotionTier": 1, "DBClusterParameterGroupStatus": "in-sync", "IsClusterWriter": false, "DBInstanceIdentifier": "sample-cluster" }, { "PromotionTier": 1, "DBClusterParameterGroupStatus": "in-sync", "IsClusterWriter": true, "DBInstanceIdentifier": "sample-cluster2" } ], "PreferredMaintenanceWindow": "sat:04:30-sat:05:00", "VpcSecurityGroups": [ { "VpcSecurityGroupId": "sg-77186e0d", "Status": "active" } ], "Engine": "docdb", "ReaderEndpoint": "sample-cluster.cluster-ro-corcjozrlsfc.us-west-2.docdb.amazonaws.com", "DBSubnetGroup": "default", "MultiAZ": true, "AvailabilityZones": [ "us-west-2a", "us-west-2c", "us-west-2b" ], "EarliestRestorableTime": "2019-03-15T20:30:47.020Z", "DbClusterResourceId": "cluster-UP4EF2PVDDFVHHDJQTYDAIGHLE", "DBClusterArn": "arn:aws:rds:us-west-2:123456789012:cluster:sample-cluster", "BackupRetentionPeriod": 3, "HostedZoneId": "ZNKXH85TT8WVW", "StorageEncrypted": false, "EnabledCloudwatchLogsExports": [ "audit" ], "AssociatedRoles": [], "EngineVersion": "3.6.0", "Port": 27017, "Status": "available" } ] } For more information, see `Describing Amazon DocumentDB Clusters <https://docs.aws.amazon.com/documentdb/latest/developerguide/db-cluster-view-details.html>`__ in the *Amazon DocumentDB Developer Guide*.
