**To promote a DB cluster read replica**

The following ``promote-read-replica-db-cluster`` example promotes the specified read replica to become a standalone DB cluster. ::

    aws rds promote-read-replica-db-cluster \
        --db-cluster-identifier mydbcluster-1

Output::

    {
        "DBCluster": {
            "AllocatedStorage": 1,
            "AvailabilityZones": [
                "us-east-1a",
                "us-east-1b",
                "us-east-1c"
            ],
            "BackupRetentionPeriod": 1,
            "DatabaseName": "",
            "DBClusterIdentifier": "mydbcluster-1",
            ...some output truncated...
        }
    }
