在 Terraform（而不是 S3）中重命名 s3 存储桶会导致创建然后销毁？

Question

我想稍微重构我的 Terraform 脚本。

前：

resource "aws_s3_bucket" "abc" {
  bucket = "my-bucket"
  acl    = "private"
  region = "${var.aws_region}"

  tags = {
    Name = "My bucket"
  }

  versioning {
    enabled = true
    mfa_delete = false
  }
}

后：

resource "aws_s3_bucket" "def" {
  bucket = "my-bucket"
  acl    = "private"
  region = "${var.aws_region}"

  tags = {
    Name = "My bucket"
  }

  versioning {
    enabled = true
    mfa_delete = false
  }
}

如您所见，只有Terraform 中的名称发生了变化 ( abc-> def)。

但是，这会导致在terraform plan.

我希望 Terraform 将存储桶识别为相同的（它们具有相同的属性，包括bucket）。

问题：

• 为什么是这样？
• 有没有办法在不破坏基础设施的情况下重构 Terraform 脚本？

You can use terraform state mv, to reflect this change in the state.

In you case, this would be

terraform state mv aws_s3_bucket.abc aws_s3_bucket.def

From my own experience, this works well and I recommend doing it instead of working with bad names.

Terraform does not recognize such changes, no :-)
