使用 tidbcloud_dedicated_vpc_peering 资源

本文档介绍如何使用 tidbcloud_dedicated_vpc_peering 资源管理 TiDB Cloud 专属 VPC 对等连接。

tidbcloud_dedicated_vpc_peering 资源的功能包括:

  • 创建 TiDB Cloud 专属 VPC 对等连接。
  • 导入 TiDB Cloud 专属 VPC 对等连接。
  • 删除 TiDB Cloud 专属 VPC 对等连接。

前置条件

创建 TiDB Cloud 专属 VPC 对等连接

你可以使用 tidbcloud_dedicated_vpc_peering 资源来创建 TiDB Cloud 专属 VPC 对等连接。

以下示例展示了如何创建一个 TiDB Cloud 专属 VPC 对等连接。

  1. 为 TiDB Cloud 专属 VPC 对等连接创建一个目录并进入该目录。

  2. 创建一个 vpc_peering.tf 文件:

    terraform { required_providers { tidbcloud = { source = "tidbcloud/tidbcloud" } } } provider "tidbcloud" { public_key = "your_public_key" private_key = "your_private_key" } resource "tidbcloud_dedicated_vpc_peering" "example" { tidb_cloud_region_id = "your_tidb_cloud_region_id" customer_region_id = "your_customer_region_id" customer_account_id = "your_customer_account_id" customer_vpc_id = "your_customer_vpc_id" customer_vpc_cidr = "your_customer_vpc_cidr" }

    使用 resource 块来定义 TiDB Cloud 的资源,包括资源类型、资源名称和资源详情。

  3. 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_dedicated_vpc_peering.example will be created + resource "tidbcloud_dedicated_vpc_peering" "example" { + aws_vpc_peering_connection_id = (known after apply) + customer_account_id = "986330900000" + customer_region_id = "aws-us-west-2" + customer_vpc_cidr = "172.16.32.0/21" + customer_vpc_id = "vpc-0c0c7d59702000000" + labels = (known after apply) + project_id = (known after apply) + state = (known after apply) + tidb_cloud_account_id = (known after apply) + tidb_cloud_cloud_provider = (known after apply) + tidb_cloud_region_id = "aws-us-west-2" + tidb_cloud_vpc_cidr = (known after apply) + tidb_cloud_vpc_id = (known after apply) + vpc_peering_id = (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 之后获得对应的值。
  4. 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_dedicated_vpc_peering.example: Creating... tidbcloud_dedicated_vpc_peering.example: Still creating... [10s elapsed]

    资源的状态会保持为 Creating,直到你在云服务商控制台中批准 VPC 对等连接。批准后,你可以参考 批准并配置 VPC Peering,状态会变为 Active

  5. 使用 terraform showterraform state show tidbcloud_dedicated_vpc_peering.${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_dedicated_vpc_peering.example # tidbcloud_dedicated_vpc_peering.example: resource "tidbcloud_dedicated_vpc_peering" "example" { aws_vpc_peering_connection_id = "pcx-0b2e5211d48000000" customer_account_id = "986330900000" customer_region_id = "aws-us-west-2" customer_vpc_cidr = "172.16.32.0/21" customer_vpc_id = "vpc-0c0c7d59702000000" labels = { "tidb.cloud/project" = "1372813089187000000" } project_id = "13728130891870000000" state = "ACTIVE" tidb_cloud_account_id = "380838400000" tidb_cloud_cloud_provider = "aws" tidb_cloud_region_id = "aws-us-west-2" tidb_cloud_vpc_cidr = "10.250.0.0/16" tidb_cloud_vpc_id = "vpc-0b9fa4b78ef000000" vpc_peering_id = "aws-1934187953894000000" }

导入 TiDB Cloud 专属 VPC 对等连接

对于未被 Terraform 管理的 TiDB Cloud 专属 VPC 对等连接,你可以通过导入的方式让 Terraform 管理它。

例如,你可以导入一个不是通过 Terraform 创建的 VPC 对等连接。

  1. 为新的 tidbcloud_dedicated_vpc_peering 资源添加一个 import 块。

    在你的 .tf 文件中添加如下 import 块,将 example 替换为你想要的资源名称,将 ${id} 替换为 cluster_id,vpc_peering_id 的格式:

    import { to = tidbcloud_dedicated_vpc_peering.example id = "${id}" }
  2. 生成新的配置文件。

    根据 import 块为新的 tidbcloud_dedicated_vpc_peering 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。

    然后,当前目录下会生成 generated.tf 文件,包含了被导入资源的配置信息。

  3. 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_dedicated_vpc_peering.example: Importing... [id=aws-1934187953894000000,example] tidbcloud_dedicated_vpc_peering.example: Import complete [id=aws-19341879538940000000,example] 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 TiDB Cloud 专属 VPC 对等连接。

删除 TiDB Cloud 专属 VPC 对等连接

要删除 TiDB Cloud 专属 VPC 对等连接,你可以删除 tidbcloud_dedicated_vpc_peering 资源的配置,然后使用 terraform apply 命令销毁该资源:

$ terraform apply tidbcloud_dedicated_vpc_peering.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_dedicated_vpc_peering.example will be destroyed # (because tidbcloud_dedicated_vpc_peering.example is not in configuration) - resource "tidbcloud_dedicated_vpc_peering" "example" { - aws_vpc_peering_connection_id = "pcx-0b2e5211d48000000" -> null - customer_account_id = "986330900000" -> null - customer_region_id = "aws-us-west-2" -> null - customer_vpc_cidr = "172.16.32.0/21" -> null - customer_vpc_id = "vpc-0c0c7d59702000000" -> null - labels = { - "tidb.cloud/project" = "1372813089187000000" } -> null - project_id = "1372813089187000000" -> null - state = "ACTIVE" -> null - tidb_cloud_account_id = "380838000000" -> null - tidb_cloud_cloud_provider = "aws" -> null - tidb_cloud_region_id = "aws-us-west-2" -> null - tidb_cloud_vpc_cidr = "10.250.0.0/16" -> null - tidb_cloud_vpc_id = "vpc-0b9fa4b78ef000000" -> null - vpc_peering_id = "aws-1934187953894000000" -> 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_dedicated_vpc_peering.example: Destroying... tidbcloud_dedicated_vpc_peering.example: Destruction complete after 1s Apply complete! Resources: 0 added, 0 changed, 1 destroyed.

此时,如果你运行 terraform show 命令,将不会有任何输出,因为该资源已被清除:

$ terraform show
