尝试在 Azure 云提供商上创建私有 link 时出现问题

Question

我正在尝试开发在 Azure 上创建虚拟机并使用私有 link 将其连接到 Azure Postgresql 实例的 terraform 脚本。我总是收到此错误：

Error: creating Private Endpoint "n4gx6y-endpoint" (Resource Group "PGSQLResourceGroup"): 
network.PrivateEndpointsClient#CreateOrUpdate: 
Failure sending request: StatusCode=400 -- Original Error: 
Code="IncorrectPrivateLinkServiceConnectionGroupId" 
Message="Call to Microsoft.DBforPostgreSQL/servers failed. 
Error message: Private Link Service Connection Group Id is 
incorrect for Azure Database for PostgreSQL" Details=[]

  on main.tf line 68, in resource "azurerm_private_endpoint" "example":
  68: resource "azurerm_private_endpoint" "example" {

这是脚本：

这里是 github 存储库，其中包含相同的脚本，一个用于 Postgres，一个用于 Mariadb。该错误仅出现在 Postgres 中。

Answer 1

问题实际上与脚本的这一部分有关：

  private_service_connection {
    name                           = "${random_string.random.result}-privateserviceconnection"
    private_connection_resource_id = azurerm_postgresql_server.example.id
    subresource_names              = ["postgresServer"] # <-- HERE!
    is_manual_connection           = false
  }

事实证明，每个受支持的私有 link Azure 托管服务都有硬编码的子资源名称。对于 MariaDB 实例，它是 mariadbServer 对于 Postgres，它是 postgresqlServer。我错误地放在那里 postgresServer 认为它只是任意值。

Answer 2

private_service_connection {
  name                           = "${random_string.random.result}- 
  privateserviceconnection"
  private_connection_resource_id = azurerm_postgresql_server.example.id
  subresource_names              = ["postgresqlServer"] # <-- HERE!
  is_manual_connection           = false

}
