处理已经存在的【terraform】tfstate的情况

总结

以下是如何处理在terraform import时遇到已存在的对象时被指责的备忘录：

错误

Error: Resource already managed by Terraform

Terraform is already managing a remote object for
module.network.aws_security_group.XXX. To import to this
address you must first remove the existing object from the state.

处理方法

进行备份

删除目标后，问题发生之前就进行备份，以免出现恐怖情况。

$ terraform state pull > tfstate.bk

参照 state 的清单或参照通过 ① 创建的备份文件。

$ terraform state list

只需一种方式：确认目标的内容。

$ terraform state show module.XXX.XXX

删除state中所记录的目标。

$ terraform state rm module.XXX.XXX

执行import

$ terraform import module.XXX.XXX
module.network.aws_security_group.XXX: Importing from ID "sg-XXX"...
module.network.aws_security_group.XXX: Import prepared!
  Prepared aws_security_group for import
module.network.aws_security_group.XXX: Refreshing state... [id=sg-XXX]

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.
