Amazon web services 地形破坏命令显示计划不正确

我现在还不熟悉地形和学习。我已经使用terraform代码创建了一个aws实例，它在我的测试环境中工作。我用terraform destroy消灭了同一个实例，它成功了。现在，当我尝试创建新实例时，terraform plan显示了要添加的2个资源，而不是1个。下面是我的计划输出

C:\terraform>terraform plan

Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

您的地形图显示它将添加两个资源：一个aws_实例和一个aws_密钥对。aws_密钥对允许您

这是因为当您运行terraform plan时，terraform会查看当前目录中的所有.tf文件，并尝试创建它找到的所有资源。您可以通过从当前目录中删除aws_key_pair.tf来修复此问题，这使得terraform plan只能找到要创建的aws_实例

有关更多详细信息，请参阅文档：

默认情况下，计划不需要标志，并在当前目录中查找要刷新的配置和状态文件

请编辑您的问题并分享您的地形图输出。谢谢嗨，我现在刚接触地形和学习。我已经使用terraform代码创建了一个aws实例，它在我的测试环境中工作。我用terraform destroy清除了同一个实例，并且成功了。现在，当我尝试创建新实例时，terraform计划显示要添加2个资源，而不是1个。下面是我的计划输出。计划：2添加，0更改，0销毁。我通过在aws_instance.tf文件的末尾添加key_name=xy对来修复它，并从terraform目录中删除了aws_key_pair.tf文件，现在它工作得很好。请帮助我了解aws密钥对角色，。
