问题描述
我正在尝试通过引用第一个群集的恢复时间点创建一个新群集和另一个群集。 对于第一个tfvar块-它将创建一个新的aurora MySQL集群aurora-cluster-mySQL-serverless 在第二个tfvar块中,它应该从源aurora-cluster-mySQL-serverless创建一个新的集群aurora-cluster-mysql-serverless。但无法找到或无法访问获取异常";源群集:auora-cluster-mysql-serverless";,即使它已创建群集。下面是我的结构。

推荐答案
您可以在一个模块中创建一个集群,然后在另一个模块中恢复时间点,而不是这样做。你可以通过这种方式达到你想要的效果。
