无法使用“Terraform init -reconfigure`”将S3后端中的Terraform远程状态转换为本地状态
无法使用“Terraform init -reconfigure`”将S3后端中的Terraform远程状态转换为本地状态
提问于 2021-06-28 08:24:02
我正在使用Terraformv1.0.0，并使用AWS S3和AWS DynamoDB创建了一个远程后端，如Terraform中所解释的&由Yevgeniy运行：
- 我为S3桶和DynamoDB表编写了代码，并通过
terraform apply创建了资源。 - 我在代码中添加了
terraform { backend "S3" {} } - 我创建了一个包含所有相关参数的
backend.hcl文件 - 我通过调用S3将本地状态移动到
terraform init -backend-config=backend.hcl
现在，我希望将远程状态转换回本地状态，以便安全地删除远程后端。Brikman解释说，要做到这一点，必须删除backend配置并调用terraform init。当我尝试这个的时候，我看到了这个：
$ terraform init
Initializing modules...
Initializing the backend...
╷
│ Error: Backend configuration changed
│
│ A change in the backend configuration has been detected, which may require migrating existing state.
│
│ If you wish to attempt automatic migration of the state, use "terraform init -migrate-state".
│ If you wish to store the current configuration with no changes to the state, use "terraform init -reconfigure".
╵我认为正确的方法是使用-reconfigure，乍一看，这似乎是可行的：
$ terraform init -reconfigure
Initializing modules...
Initializing the backend...
Initializing provider plugins...
- Reusing previous version of hashicorp/random from the dependency lock file
- Reusing previous version of hashicorp/aws from the dependency lock file
- Using previously-installed hashicorp/aws v3.47.0
- Using previously-installed hashicorp/random v3.1.0
Terraform has been successfully initialized!但是，执行terraform plan显示初始化没有成功：
$ terraform plan
╷
│ Error: Backend initialization required, please run "terraform init"
│
│ Reason: Unsetting the previously set backend "s3"
│
│ The "backend" is the interface that Terraform uses to store state,
│ perform operations, etc. If this message is showing up, it means that the
│ Terraform configuration you're using is using a custom configuration for
│ the Terraform backend.
│
│ Changes to backend configurations require reinitialization. This allows
│ Terraform to set up the new configuration, copy existing state, etc. Please run
│ "terraform init" with either the "-reconfigure" or "-migrate-state" flags to
│ use the current configuration.
│
│ If the change reason above is incorrect, please verify your configuration
│ hasn't changed and try again. At this point, no changes to your existing
│ configuration or state have been made.
╵取消后端的唯一方法似乎是通过terraform init -migrate-state
$ terraform init -migrate-state
Initializing modules...
Initializing the backend...
Terraform has detected you're unconfiguring your previously set "s3" backend.
Do you want to copy existing state to the new backend?
Pre-existing state was found while migrating the previous "s3" backend to the
newly configured "local" backend. No existing state was found in the newly
configured "local" backend. Do you want to copy this state to the new "local"
backend? Enter "yes" to copy and "no" to start with an empty state.
Enter a value: yes
Successfully unset the backend "s3". Terraform will now operate locally.尽管Terraform明确告诉我，通过terraform init -reconfigure转换状态是不可能的吗？如果是这样的话，terraform init -reconfigure到底是做什么的？

下面的工作为我解决了这个问题。
添加下面并运行terraform init
terraform {后端“本地”{}
