根据我的研究，我发现使用 CLI 创建一个 Aurora 集群的唯一方法是从现有快照创建一个内部有实例的实例：

1) 从现有集群创建快照

2) 从快照启动集群

3) 将实例添加到集群中

因此，我使用最新的 AWS CLI 版本运行的命令如下（以及输出）：

aws rds create-db-cluster-snapshot \
  --db-cluster-snapshot-identifier analytics-replica-db \
  --db-cluster-identifier prodcluster

哪个输出

{
    "DBClusterSnapshot": {
        "Engine": "aurora",
        "SnapshotCreateTime": "2017-07-24T15:08:12.836Z",
        "VpcId": "vpc-ID",
        "DBClusterIdentifier": "cluster_name",
        "DBClusterSnapshotArn": "arn:aws:rds:eu-west-1:aws_account:cluster-snapshot:analytics-replica-db",
        "MasterUsername": "db_username",
        "LicenseModel": "aurora",
        "Status": "creating",
        "PercentProgress": 0,
        "DBClusterSnapshotIdentifier": "analytics-replica-db",
        "IAMDatabaseAuthenticationEnabled": false,
        "ClusterCreateTime": "2016-04-14T11:10:02.413Z",
        "StorageEncrypted": false,
        "AllocatedStorage": 1,
        "EngineVersion": "5.6.10a",
        "SnapshotType": "manual",
        "AvailabilityZones": [
            "eu-west-1a",
            "eu-west-1b",
            "eu-west-1c"
        ],
        "Port": 0
    }
}

之后，我使用以下命令创建集群：

aws rds restore-db-cluster-from-snapshot \
  --db-cluster-identifier analytics-replica-cluster \ …
