我想在私有 DNS 区域中为我的内部 API 管理实例创建 DNS A 记录azure-api.net以及 API 管理部署：

var privateDnsZoneName = 'azure-api.net'
resource privateDnsZone 'Microsoft.Network/privateDnsZones@2020-06-01' = {
  name: privateDnsZoneName
  location: 'Global'
}

resource privateDnsZoneEntry 'Microsoft.Network/privateDnsZones/A@2020-06-01' = {
  name: apim.name
  parent: privateDnsZone
  properties: {
    aRecords: [for addr in apim.properties.privateIPAddresses: {
      ipv4Address: addr
    }]
    ttl: 3600
  }
}

但是，在部署时会导致此错误：

Line |
  57 |  New-AzResourceGroupDeployment -ResourceGroupName $ResourceGroupName `
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | 17:12:13 - Error: Code=InvalidTemplate; Message=Deployment template validation failed: 'The template resource
     | '[format('{0}/{1}', variables('privateDnsZoneName'), parameters('apimName'))]' at line '221' and column '9' is not
     | valid: The template function 'reference' is not expected at this location. Please see
     | https://aka.ms/arm-template-expressions for usage details.. Please see https://aka.ms/arm-template-expressions for
     | usage details.'.

这个地方似乎reference()不支持该功能（在ARM中）：

{
  "type": "Microsoft.Network/privateDnsZones/A",
  "apiVersion": "2020-06-01",
  "name": "[format('{0}/{1}', variables('privateDnsZoneName'), parameters('apimName'))]",
  "properties": {
    "copy": [
      {
        "name": "aRecords",
        "count": "[length(reference(resourceId('Microsoft.ApiManagement/service', parameters('apimName'))).privateIPAddresses)]",
        "input": {
          "ipv4Address": "[reference(resourceId('Microsoft.ApiManagement/service', parameters('apimName'))).privateIPAddresses[copyIndex('aRecords')]]"
        }
      }
    ],
    "ttl": 3600
  },
  "dependsOn": [
    "[resourceId('Microsoft.ApiManagement/service', parameters('apimName'))]",
    "[resourceId('Microsoft.Network/privateDnsZones', variables('privateDnsZoneName'))]"
  ]
}

尝试在两者之间使用变量会导致相同的错误 - 因为实际上生成了相同的 ARM JSON。

var privateDnsZoneName = 'azure-api.net'
resource privateDnsZone 'Microsoft.Network/privateDnsZones@2020-06-01' = {
  name: privateDnsZoneName
  location: 'Global'
}

var apimPrivateIPAddresses = apim.properties.privateIPAddresses

resource privateDnsZoneEntry 'Microsoft.Network/privateDnsZones/A@2020-06-01' = {
  name: apim.name
  parent: privateDnsZone
  properties: {
    aRecords: [for addr in apimPrivateIPAddresses: {
      ipv4Address: addr
    }]
    ttl: 3600
  }
}

我发现除了将私有 DNS 区域 + 记录创建拆分为二头肌模块并摆脱该reference()功能之外别无他法：

param privateDnsZoneName string = 'azure-api.net'
param privateDnsARecordName string
param privateDnsARecordAddresses array

resource privateDnsZone 'Microsoft.Network/privateDnsZones@2020-06-01' = {
  name: privateDnsZoneName
  location: 'Global'
}

resource privateDnsZoneEntry 'Microsoft.Network/privateDnsZones/A@2020-06-01' = {
  name: privateDnsARecordName
  parent: privateDnsZone
  properties: {
    aRecords: [for addr in privateDnsARecordAddresses: {
      ipv4Address: addr
    }]
    ttl: 3600
  }
}

并将privateIPAddresses数组传递给模块。

module privateDnsEntry './private-dns.bicep' = {
  name: 'apim-private-dns'
  params: {
    privateDnsZoneName: 'azure-api.net'
    privateDnsARecordName: apim.name
    privateDnsARecordAddresses: apim.properties.privateIPAddresses
  }
}
