使用私有存储帐户创建 SQL 服务器漏洞评估资源失败

Question

我有一个 SQL 服务器资源，我尝试使用 Terraform 为其创建一个 azurerm_mssql_server_vulnerability_assessment。为此，我使用了一个私人存储帐户（没有 public 访问/私人端点）。我的代码如下：

resource "azurerm_mssql_server_security_alert_policy" "mssql_security_alert_policy" {
  resource_group_name = var.resource_group_name
  server_name         = azurerm_mssql_server.this.name
  state               = "Enabled"
}

resource "azurerm_mssql_server_vulnerability_assessment" "mssql_vulnerability_assessment" {
  server_security_alert_policy_id = azurerm_mssql_server_security_alert_policy.mssql_security_alert_policy.id
  storage_container_path          = "${azurerm_storage_account.sql_defender_storage_account.primary_blob_endpoint}${azurerm_storage_container.sql_defender_storage_account_container.name}/"
  storage_account_access_key      = azurerm_storage_account.sql_defender_storage_account.primary_access_key

  recurring_scans {
    enabled = true
  }
}

# Allow the database to act as a contributor to the storage account for vulnerability assessments
resource "azurerm_role_assignment" "sql_blob_container_contributor" {
  principal_id = azurerm_mssql_server.this.identity[0].principal_id
  role_definition_name = "Storage Blob Data Contributor"
  scope        = azurerm_storage_account.sql_defender_storage_account.id
}

对于存储帐户：

resource "azurerm_storage_account" "sql_defender_storage_account" {
  name                     = "sqldefender${var.stage}"
  account_replication_type = "LRS"
  account_tier             = "Standard"
  location                 = var.location
  resource_group_name      = var.resource_group_name

  network_rules {
    default_action = var.deny_public_access ? "Deny" : "Allow"
    bypass = [
      "AzureServices", "Logging", "Metrics"
    ]

    private_link_access {
      endpoint_resource_id = azurerm_mssql_server.this.id
    }
    
  }

  tags = module.label_mssql_server.tags
}

resource "azurerm_private_endpoint" "mssql_server_defender_storage_account" {
  location            = var.location
  name                = "pe-to-${var.private_endpoint_name}-${azurerm_storage_account.sql_defender_storage_account.name}-blob"
  resource_group_name = var.resource_group_name
  subnet_id           = var.private_endpoints_subnet_id
  tags                = module.label_mssql_server.tags

  private_service_connection {
    is_manual_connection           = false
    //noinspection HILUnresolvedReference
    name                           = "private-serviceconnection"
    private_connection_resource_id = azurerm_storage_account.sql_defender_storage_account.id
    subresource_names              = [
      "blob"
    ]
  }
}

# Create a DNS record for the private storage account
resource "azurerm_private_dns_a_record" "sql_defender_storage_account" {
  provider = azurerm.common

  name    = azurerm_storage_account.sql_defender_storage_account.name
  records = azurerm_private_endpoint.mssql_server_defender_storage_account.custom_dns_configs.0.ip_addresses

  resource_group_name = var.common_resource_group_name
  ttl                 = 300
  zone_name           = var.blob_storage_dns_zone
  tags                = module.label_mssql_server.tags
}

# Create the storage account name
resource "azurerm_storage_container" "sql_defender_storage_account_container" {
  name                  = "sqldefendercontainer"
  storage_account_name  = azurerm_storage_account.sql_defender_storage_account.name
  container_access_type = "private"
  depends_on = [ azurerm_private_dns_a_record.sql_defender_storage_account ]
}

然而，在尝试应用创建的计划时，出现以下错误：

Error: updataing mssql server vulnerability assessment: sql.ServerVulnerabilityAssessmentsClient#CreateOrUpdate: Failure responding to request: StatusCode=504 --

Original Error: autorest/azure: Service returned an error.

Status=504 Code="GatewayTimeout" Message="The gateway did not receive a response from 'Microsoft.Sql' within the specified time period."

我不太确定为什么会这样。我怀疑这可能与专用端点有关，但我不是 100% 确定。任何人都可以在这里阐明一些信息吗？

正如我在评论中提到的，我们需要为 SQL 服务器使用托管身份，然后为从 terraform 创建的存储提供相同的身份 Storage Blob Data Contributor。

我在现有 SQL 服务器上启用了系统管理身份，然后从 terraform 代码提供了存储 Blob 数据贡献者。

然后我使用下面的代码来满足您的要求：

provider "azurerm" {
  features{}
}

#SystemMangedIdentity For the SQL Server
data "azuread_service_principal" "sqlsystemidentity" {
   display_name = "ansuman-sql"
}

  name = "myresourcegroup"
}
data "azurerm_virtual_network" "vnet" {
  name = "ansuman-vnet"
  resource_group_name = data.azurerm_resource_group.rg.name
}
data "azurerm_subnet" "subnet" {
  name = "storage"
  virtual_network_name = data.azurerm_virtual_network.vnet.name
  resource_group_name = data.azurerm_resource_group.rg.name
}

data "azurerm_mssql_server" "server" {
  name = "ansuman-sql"
  resource_group_name = data.azurerm_resource_group.rg.name
}

resource "azurerm_storage_account" "sql_defender_storage_account" {
  name                     = "sqldefenderansuman123"
  account_replication_type = "LRS"
  account_tier             = "Standard"
  location                 = data.azurerm_resource_group.rg.location
  resource_group_name      = data.azurerm_resource_group.rg.name
  network_rules {
    default_action = "Deny"
    ip_rules = ["myclientip"]
    bypass = [
      "AzureServices", "Logging", "Metrics"
    ]
  }
}

resource "azurerm_role_assignment" "sqltoblobcontributor" {
  scope                = azurerm_storage_account.sql_defender_storage_account.id
  role_definition_name = "Storage Blob Data Contributor"
  principal_id         = data.azuread_service_principal.sqlsystemidentity.object_id
}

resource "azurerm_private_endpoint" "mssql_server_defender_storage_account" {

    //noinspection HILUnresolvedReference
    name                           = "private-serviceconnection"
    private_connection_resource_id = azurerm_storage_account.sql_defender_storage_account.id
    subresource_names              = [
      "blob"
    ]
  }
}

# private DNS
resource "azurerm_private_dns_zone" "example" {
  name                = "privatelink.blob.core.windows.net"
  resource_group_name = data.azurerm_resource_group.rg.name
  depends_on = [
    azurerm_private_endpoint.mssql_server_defender_storage_account
  ]
}

#private DNS Link
resource "azurerm_private_dns_zone_virtual_network_link" "example" {
  name                  = "${azurerm_storage_account.sql_defender_storage_account.name}-dnslink"
  resource_group_name   = data.azurerm_resource_group.rg.name
  private_dns_zone_name = azurerm_private_dns_zone.example.name
  virtual_network_id    = data.azurerm_virtual_network.vnet.id
  registration_enabled = false
}

# Create the storage account name
resource "azurerm_storage_container" "sql_defender_storage_account_container" {
  name                  = "sqldefendercontainer"
  storage_account_name  = azurerm_storage_account.sql_defender_storage_account.name
  container_access_type = "private"
  depends_on = [ azurerm_private_dns_zone_virtual_network_link.example]
}

resource "azurerm_mssql_server_security_alert_policy" "mssql_security_alert_policy" {
  resource_group_name = data.azurerm_resource_group.rg.name
  server_name         = data.azurerm_mssql_server.server.name
  state               = "Enabled"
}

resource "azurerm_mssql_server_vulnerability_assessment" "mssql_vulnerability_assessment" {
  server_security_alert_policy_id = azurerm_mssql_server_security_alert_policy.mssql_security_alert_policy.id
  storage_container_path          = "${azurerm_storage_account.sql_defender_storage_account.primary_blob_endpoint}${azurerm_storage_container.sql_defender_storage_account_container.name}/"
}

注：

我从漏洞评估块中删除了存储访问密钥参数，因为它是可选的，在使用身份时不是必需的。

输出：
