使用 tidbcloud_serverless_export 资源
本文档介绍如何使用 tidbcloud_serverless_export 资源管理 TiDB Cloud Starter 或 TiDB Cloud Essential 集群的数据导出任务。
tidbcloud_serverless_export 资源的功能包括:
- 为 TiDB Cloud Starter 或 TiDB Cloud Essential 集群创建数据导出任务。
- 导入 TiDB Cloud Starter 或 TiDB Cloud Essential 集群的数据导出任务。
- 删除 TiDB Cloud Starter 或 TiDB Cloud Essential 集群的数据导出任务。
前置条件
为 TiDB Cloud Starter 或 TiDB Cloud Essential 集群创建数据导出任务
你可以使用 tidbcloud_serverless_export 资源为 TiDB Cloud Starter 或 TiDB Cloud Essential 集群创建数据导出任务。
为导出任务创建一个目录并进入该目录。
为数据导出任务创建一个
export.tf文件。以下是
export.tf文件的示例:terraform { required_providers { tidbcloud = { source = "tidbcloud/tidbcloud" } } } provider "tidbcloud" { public_key = "your_public_key" private_key = "your_private_key" } resource "tidbcloud_serverless_export" "example" { cluster_id = 10476959660988000000 }使用
resource块定义 TiDB Cloud 的资源,包括资源类型、资源名称和资源详情。- 要使用 serverless 导出资源,将资源类型设置为
tidbcloud_serverless_export。 - 资源名称可以根据需要自定义,例如
example。 - 资源详情可以根据 serverless 导出规范信息进行配置。
- 获取 serverless 导出规范信息,请参见 tidbcloud_serverless_export (Resource)。
- 要使用 serverless 导出资源,将资源类型设置为
运行
terraform apply命令。应用资源时,不建议使用terraform apply --auto-approve。$ terraform apply Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols: + create Terraform will perform the following actions: # tidbcloud_serverless_export.example will be created + resource "tidbcloud_serverless_export" "example" { + cluster_id = "10476959660988000000" + complete_time = (known after apply) + create_time = (known after apply) + created_by = (known after apply) + display_name = (known after apply) + expire_time = (known after apply) + export_id = (known after apply) + export_options = (known after apply) + reason = (known after apply) + snapshot_time = (known after apply) + state = (known after apply) + target = (known after apply) + update_time = (known after apply) } Plan: 1 to add, 0 to change, 0 to destroy. Do you want to perform these actions? Terraform will perform the actions described above. Only 'yes' will be accepted to approve. Enter a value:在上述结果中,Terraform 为你生成了一个执行计划,描述了 Terraform 将要执行的操作:
- 你可以检查配置与当前状态之间的差异。
- 你还可以看到本次
apply的结果。它将新增一个资源,不会有资源被更改或销毁。 known after apply表示你将在apply后获得对应的值。
如果你的计划没有问题,输入
yes继续:Do you want to perform these actions? Terraform will perform the actions described above. Only 'yes' will be accepted to approve. Enter a value: yes tidbcloud_serverless_export.example: Creating... tidbcloud_serverless_export.example: Creation complete after 1s Apply complete! Resources: 1 added, 0 changed, 0 destroyed.在本示例中,
tidbcloud_serverless_export.example资源将创建一个导出任务,用于导出整个集群的数据。该资源是异步的。你可以使用
terraform refresh获取其最新状态。使用
terraform show或terraform state show tidbcloud_serverless_export.${resource-name}命令检查资源的状态。前者会显示所有资源和数据源的状态。$ terraform state show tidbcloud_serverless_export.example # tidbcloud_serverless_export.example: resource "tidbcloud_serverless_export" "example" { cluster_id = "10476959660988000000" create_time = "2025-06-16T08:54:10Z" created_by = "apikey-S2000000" display_name = "SNAPSHOT_2025-06-16T08:54:10Z" export_id = "exp-ezsli6ugtzg2nkmzaitt000000" export_options = { compression = "GZIP" file_type = "CSV" } snapshot_time = "2025-06-16T08:54:10Z" state = "RUNNING" target = { type = "LOCAL" } }
导入 TiDB Cloud Starter 或 TiDB Cloud Essential 集群的数据导出任务
如果某个 TiDB Cloud Starter 或 TiDB Cloud Essential 集群的数据导出任务未被 Terraform 管理,你可以通过导入将其纳入 Terraform 管理。
为新的
tidbcloud_serverless_export资源添加一个 import 块。在你的
.tf文件中添加如下 import 块,将example替换为你期望的资源名称,将${id}替换为cluster_id,export_id的格式:import { to = tidbcloud_serverless_export.example id = "${id}" }生成新的配置文件。
根据 import 块为新的 serverless export 资源生成新的配置文件:
terraform plan -generate-config-out=generated.tf上述命令中不要指定已存在的
.tf文件名,否则 Terraform 会返回错误。审查并应用生成的配置。
审查生成的配置文件,确保其符合你的需求。你也可以选择将该文件内容移动到你喜欢的位置。
然后,运行
terraform apply导入你的基础设施。应用后,示例输出如下:tidbcloud_serverless_export.example: Importing... tidbcloud_serverless_export.example: Import complete Apply complete! Resources: 1 imported, 0 added, 0 changed, 0 destroyed.
现在你可以使用 Terraform 管理已导入的导出任务。
删除 TiDB Cloud Starter 或 TiDB Cloud Essential 集群的数据导出任务
要删除 TiDB Cloud Starter 或 TiDB Cloud Essential 集群的数据导出任务,你可以删除 tidbcloud_serverless_export 资源的配置,然后使用 terraform apply 命令销毁该资源:
$ terraform apply
tidbcloud_serverless_export.example: Refreshing state...
Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
- destroy
Terraform will perform the following actions:
# tidbcloud_serverless_export.example will be destroyed
# (because tidbcloud_serverless_export.example is not in configuration)
- resource "tidbcloud_serverless_export" "example" {
- cluster_id = "10476959660988000000" -> null
- create_time = "2025-06-16T08:54:10Z" -> null
- created_by = "apikey-S2000000" -> null
- display_name = "SNAPSHOT_2025-06-16T08:54:10Z" -> null
- export_id = "exp-ezsli6ugtzg2nkmzaitt000000" -> null
- export_options = {
- compression = "GZIP" -> null
- file_type = "CSV" -> null
} -> null
- snapshot_time = "2025-06-16T08:54:10Z" -> null
- state = "RUNNING" -> null
- target = {
- type = "LOCAL" -> null
} -> null
}
Plan: 0 to add, 0 to change, 1 to destroy.
Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.
Enter a value: yes
tidbcloud_serverless_export.example: Destroying...
tidbcloud_serverless_export.example: Destruction complete after 2s
Apply complete! Resources: 0 added, 0 changed, 1 destroyed.
现在,如果你运行 terraform show 命令,将不会显示任何被管理的资源,因为该资源已被清除:
$ terraform show
