Terraform Destroy Command 顯示不正確的計划

Question

我是 Terraform 的新手，現在正在學習。 我使用有效的 terraform 代碼創建了一個 aws 實例（我有測試環境）。 我使用“ terraform destroy ”消滅了同一個實例，它成功了。 現在，當我嘗試創建新實例時，“ terraform plan ”顯示要添加的 2 個資源而不是 1 個。下面是我的計划輸出。

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 計划顯示它將添加 2 個資源：一個aws_instance和一個aws_key_pair 。 aws_key_pair允許您控制對 EC2 實例的登錄訪問。

這是因為當您運行terraform plan ，Terraform 會查看當前目錄中的所有.tf文件並嘗試創建它找到的所有資源。 您可以通過從當前目錄中刪除aws_key_pair.tf來解決此問題，這使得terraform plan只能找到要創建的aws_instance 。

默認情況下，計划不需要標志並在當前目錄中查找要刷新的配置和狀態文件。
