Terraform Destroy Command 显示不正确的计划

Question

我是 Terraform 的新手，现在正在学习。 我使用有效的 terraform 代码创建了一个 aws 实例（我有测试环境）。 我使用“ 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:

Plan: 2 to add, 0 to change, 0 to destroy.

您的 Terraform 计划显示它将添加 2 个资源：一个aws_instance和一个aws_key_pair 。 aws_key_pair允许您控制对 EC2 实例的登录访问。

这是因为当您运行terraform plan ，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来解决此问题，这使得terraform plan只能找到要创建的aws_instance 。

有关更多详细信息，请参阅terraform 计划文档：

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。
